1About Scripting in LiveCycle Designer
As part of the form design process, a form developer can use calculations and scripts to provide a richer
user experience. You can add calculations and scripts to most form fields and objects. For example, the
following JavaScript script multiplies the values of two numeric fields together and displays the result in a
third numeric field:
NumericField3.rawValue = NumericField1.rawValue * NumericField2.rawValue;
At a more advanced level, you can create your own functions tailored towards your own custom form
processing needs.
LiveCycle Designer supports two scripting languages, each geared towards the needs of a particular type
of form developer. FormCalc is a straightforward, easy-to-use calculation language that is modelled on
common spreadsheet functionality. It includes a variety of built-in functions designed to reduce the
amount of time you need to spend developing your form design. JavaScript, a powerful scripting
language, provides you with a great deal of flexibility when creating your scripts and allows you to
leverage any existing knowledge of the language.
Remember that scripting on a form is entirely optional. You can choose to take advantage of scripting to
provide a richer user experience, but many of the most powerful features available during form creation
are available in LiveCycle Designer without the use of scripts. However, through scripting, you can
manipulate and control almost all aspects of your form design.
How scripting works
LiveCycle Designer scripting uses an event-based model that allows you to alter various aspects of objects
on a form at run time. As a form designer, you add scripts to objects based on when you want the script to
execute. For example, you might place the following script on the click event of a button object so that
at run time, when a user clicks the button, a message box appears with a message:
xfa.host.messageBox("This is a message for a form filler.", "User Feedback", 3);
Scripts associated with a particular event execute whenever that event occurs. Some events can occur
multiple times within the same form filling session. For example, the following script adds one to the
current value of a numeric field:
NumericField1.rawValue = NumericField1.rawValue + 1;
If you add this script to the calculate event for NumericField1, when you open the form for the first
time, NumericField1 displays the value 2. This indicates that the calculate event occurred twice in
the sequence of events that occurred when the form was opened.

2Configuring LiveCycle Designer Workspace for
Scripting
About the Script Editor
The Script Editor within LiveCycle Designer is where you create, modify, and view the calculations and
scripts of a particular form.
The Script Editor itself has both a single-line view and a multiline view, which you can easily switch
between, depending on your current needs. Single-line view is designed to maximize the amount of space
dedicated to the Layout Editor and other palettes, whereas multiline view is designed to maximize the
amount of space for writing script.
Show Lists all form design events that support user-defined scripting. Any events that do not apply to a
particular object appear dimmed. Events that contain a calculation or script display an asterisk (*) beside
the name of the event.
Show Events for Child Objects Displays the event you have currently selected in the Show list for
the current object and all of its child objects. If you select the uppermost object in the Hierarchy palette,
this option displays the event you have currently selected in the Show list for all objects on your form.
Functions Displays a list of available built-in FormCalc or JavaScript functions, depending on the
scripting language you currently have selected in the Language list.
To place a function onto your script editing field, select a function from the list and press Enter.
Enter Script Source Changes Saves your script to your form design. Click this button after you have
finished writing your script. If you do not save your script in this manner, it may not execute correctly or
may be lost.
Cancel Script Source Changes Undoes any changes you made to a particular calculation or script.
This button applies only to the current editing session and does not act as a multiple undo feature.

Language Specifies the scripting language you want to use for the current calculation or script. Two
options are available:
●FormCalc is a native Adobe calculation language typically used for shorter scripts, such as simple
calculations.
●JavaScript is a robust and flexible scripting language suitable for more complex scripts.
Run At Specifies where the calculation or script will execute. Three options are available:
●Client Calculations and scripts execute while the client application (for example, Acrobat,
Adobe Reader, or a web browser) processes the form.
●Server ●Calculations and scripts execute while the server application (for example, LiveCycle Forms)
processes the form.
●Client and server ●Calculations and scripts execute while the server application (for example,
LiveCycle Forms) processes the form, except in cases where the HTML client application supports
client-side scripting. For example, a script that accesses a database to prefill data on a form.
To show the Script Editor
❖Select Window > Script Editor.
Note: You can use the Expand button to quickly dock or undock the Script Editor when it is displayed in
the LiveCycle Designer workspace.
To change from single-line to multiline view
❖Drag the Script Editor palette bar until the palette is the required size.
Note: Multiline view adds the All Events and Events with Scripts options to the Show list. The All Events
option displays all of the events for a particular form design object, even if the events do not
contain any calculations or scripts. The Events with Scripts option displays only those events of a
particular object that contain calculations or scripts.
To set the default scripting language
1. Select File > Form Properties.
2. Click the Defaults tab.
3. Select your default scripting language from the Default Language list.
Note: This procedure sets the value of the default scripting language only for the current instance of the
form.
To avoid changing the default scripting language each time you create a form, you must modify the
corresponding form template file that is used to create a new form design.
➤To change the default scripting language for a form template
1. Create a new form design.
2. Select File > Form Properties.

6. Save the new form design as a TDS file and overwrite the corresponding form template. For example,
save the file as Letter.tds and overwrite the Letter.tds file located in Templates\Blank folder.
To display Arabic, Hebrew, Thai, and Vietnamese characters
To display Arabic, Hebrew, Thai, and Vietnamese characters in the Script Editor or XML Source tab, you
must change the font settings that LiveCycle Designer uses in these tabs. Otherwise, LiveCycle Designer
displays rectangles where the language-specific characters should be.
Note: LiveCycle Forms 7.1 does not support form designs that contain Arabic, Hebrew, Thai, and
Vietnamese fonts.
1. Select Tools > Options and select Workspace from the list on the left.
2. Select one of the following options:
●FormCalc Syntax Formatting to set the font in the Script Editor when you use FormCalc

3. In the Font box, select a font that supports your language. For example, Adobe Arabic supports Arabic,
Adobe Hebrew supports Hebrew, Adobe Thai supports Thai, and Myriad Pro and Minion Pro support
Vietnamese. You can locate the font you need for your language on the Internet if it is not already on
your system.
4. Click OK.
5. Click OK to close the Options dialog box.
Using the workspace to debug calculations and scripts
The LiveCycle Designer workspace provides a number of ways to assist you with debugging your
calculations and scripts.
The following table provides the location and purpose of some helpful debugging information located on
various LiveCycle Designer palettes and tabs.
Workspace location Purpose
Warning tab in the Report
palette
The Warning tab is the first place form developers should check when
they encounter scripting errors or other unexpected form behavior.
The Warning tab acts as a log of issues reported by LiveCycle Designer
and updates when you preview your form design using the Preview
PDF tab.
Note: For run-time error checking in JavaScript, you should activate
the JavaScript Console. For more information, see “To enable the
JavaScript Debugger for LiveCycle Designer” on page 68.
Bindings tab in the Report
palette
If you include fields on your form design that are bound to a data
source, the Binding tab can assist you by displaying lists of fields based
on how you defined their data binding. For example, you can list only
fields with Global Data Binding or only those with no data binding
defined. This feature is especially useful on forms that have a large
number of data bound fields.
Hierarchy palette You can use the Hierarchy palette to determine the location of a form
object for a reference syntax. The Hierarchy palette is a graphical
representation of the structure of a form. It displays the contents of the
Master Pages and Design View tabs.
The Hierarchy palette also displays referenced objects under the
Referenced Objects node. A referenced object is an object that is added
to a form only when it is required. Overflow leader and trailer subforms
are examples of referenced objects. Whenever data flows across
multiple pages or content areas, the overflow leader and trailer
subforms are inserted into the form in the appropriate places.

LiveCycle Designer Scripting Basics Using the workspace to debug calculations and scripts 15
You may also find it useful to change the default options for the Script Editor to make it easier to debug
your calculations and scripts. These options are in the Workspace panel of the Options dialog box, which is
available by selecting Tools > Options and then selecting Workspace from the list on the left. For example,
you can choose to display line numbers in the Script Editor or change the formatting of FormCalc or
JavaScript syntax.
Binding tab in the Object
palette
Every LiveCycle Designer object that can be bound to a data source
includes a Binding tab in the Object palette. If you bind an object on
your form design to a particular data node from your data connection,
the Default Binding (Open, Save, Submit) list displays a valid FormCalc
reference syntax for accessing that data node. You can use the
FormCalc reference syntax in other calculations or scripts for testing
purposes.
XML Source tab The XML Source tab contains the form design’s XML code. The XML
source code defines all aspects of the form. You can use the XML
Source tab to view the XML Form Object Model structure of a form
design and to understand the relationships between objects and
properties. In the XML source, the XML element names are equivalent
to the object names in the XML Form Object Model, and attributes are
equivalent to properties.
When you select an object in the Hierarchy palette and then click the
XML Source tab, the first line of the corresponding element is
highlighted. The object name in LiveCycle Designer, as listed in the
Hierarchy palette, becomes the value of the name attribute in the XML
source.
You can set options in the Tools > Options dialog box for viewing the
source in the XML Source tab, such as showing or hiding line numbers
and setting the syntax coloring.
Caution: It is recommended that you do not edit the XML source code
directly.

3Creating Calculations and Scripts
About creating calculations and scripts
LiveCycle Designer provides a wide range of calculation and scripting features that you can use to perform
a variety of tasks. For example, the following script changes the color of a text field border and the font size
of the text field value:
TextField1.border.edge.color.value = "255,0,0";
TextField1.font.typeface = "Courier New";
More complex forms can take advantage of scripting to perform data source connectivity and data
manipulation at run time. For examples of common scripting tasks, see “Examples of Common Scripting
Tasks” on page 91.
Creating calculations and scripts in LiveCycle Designer involves following a general process each time you
attach a calculation or script to an object. Although not all aspects of the process are required each time
you create a calculation or script, following the process helps to eliminate potential errors and unexpected
results.
In general, each time you create a calculation or script, you perform the following tasks:
●Select the object to which you want to attach a calculation or script. Although you can create
calculations and scripts that manipulate almost any object on your form design, not all form design
objects support form events. For a list of standard objects included in the Library palette in LiveCycle
Designer that support scripting, see “Objects that support calculations and scripts” on page 10.
●Select the form event to which you want to assign the calculation or script. The calculation or script
associated with an event executes each time the form event triggers. For example, calculations or
scripts attached to the click event of a button trigger each time the form filler clicks the button while
filling the form.
●Choose the scripting language you want to use. Depending on the form you create, you may decide to
use only FormCalc, only JavaScript, or a mixture of both languages. You can only use one scripting
language on a particular instance of a form object event.
●Choose where the calculation or script runs, either on the client application, such as Acrobat or
Adobe Reader, or on the server using LiveCycle Forms.
●Write your calculation or script in the script editing field of the Script Editor.
●Test the calculation or script either by using the Preview PDF tab or in your test environment.
Naming conventions for form design objects and variables
When creating calculations or scripts to enhance your form, you should be aware of the form design object
and variable names on your form. In general, your form should avoid using the names of XML Form Object
Model properties, methods, and objects for form design objects and variables. Using XML Form Object
Model property, method, or object names can result in calculations and scripts not executing properly.
For example, if you create a new text field named x within a subform object named Subform1, you access
the text field object using the following syntax:
Subform1.x.[expression]
Adobe LiveCycle Designer Creating Calculations and Scripts
LiveCycle Designer Scripting Basics Choosing a scripting language 17
However, subform objects already have an XML Form Object Model property named x that represents the
horizontal position of the subform on the form design.
To avoid naming conflicts, you need to choose field naming conventions that differ from the XML Form
Object Model naming conventions. For example, you can use any of the following field names for the text
field in the example above:
●horizontalValue
●x_value
●xLetter
●hValue
For more information and a list of the XML Form Object Model property, method, and object names, see
the Adobe XML Form Object Model Reference at www.adobe.com/devnet/livecycle/designing_forms.html.
Choosing a scripting language
LiveCycle Designer supports scripting with both FormCalc and JavaScript. Each scripting language
presents its advantages that you should be aware of before you write any scripts on your form.
FormCalc is a calculation language that includes a wide range of built-in functions to simplify the most
common form functionality. For example, you can use FormCalc financial functions to evaluate the size of
a loan payment based on the principle amount, interest rate, and number of payment periods.
JavaScript is a more powerful and diverse scripting language, intended to give you more flexibility and
leverage your existing scripting knowledge. For example, you can reuse your existing JavaScript functions
in LiveCycle Designer to reduce the amount of new scripting you need to create.
Note: LiveCycle Designer supports JavaScript version 1.6 or earlier.
The following table highlights some of the key differences between FormCalc and JavaScript.

Adobe LiveCycle Designer Creating Calculations and Scripts
LiveCycle Designer Scripting Basics To create a calculation or script 18
To create a calculation or script
1. Select an object on your form design that supports events. For example, add a button to a new, blank
form.
2. In the Script Editor, from the Show list, select one of the events that apply to the object. The event you
choose specifies when the script will execute. If you are writing a calculation or script that affects an
object that does not support events, you must add your calculation or script to a form design object
that does support form events. For example, using the new button object, select the click event in
the Show list.
3. In the Language list, select your scripting language. For example, for the new button object, select
JavaScript.
4. In the Run At list, select where you want the script to execute. For example, for the new button object,
select Client.
You can choose to run calculations or scripts on your client-based application (for example Acrobat or a
web browser) or on your server-based process (for example, LiveCycle Forms). When set to Client,
processing of calculations and scripts initiates after the form renders. When set to Server, processing of
calculations and scripts initiates during the form rendering process. Previewing your form by using the
Preview PDF tab simulates opening the form in Acrobat; therefore, scripts set to run at Client or Client and
Server execute.
Note: Selecting Client And Server from the Run At list causes a script to execute in either the client
application or the server application, depending on which application is used to process the form.
5. In the Script Source field, insert your FormCalc calculation or JavaScript script. You can take advantage
of the statement completion functionality of LiveCycle Designer to help you create reference syntaxes
for your calculation or script. For example, add the following JavaScript script to the new button object:
xfa.host.messageBox("Hello World!", "Creating a new script", 3);
6. Click Enter Script Source Changes to add the script to your form.
7. After you complete your form design, test and debug your calculations and scripts before putting them
into production. For example, for the new button object, preview the PDF of the form using the
Preview PDF tab. Click the button object to display message box specified in step 5.
For more information about the LiveCycle Designer objects that support scripting, see “Objects that
support calculations and scripts” on page 10.
To find text or other items
You can quickly search for every occurrence of a specific word or phrase when you are in the XML Source
tab or in the Script Editor.
1. In the XML Source tab or the Script Editor, select Edit > Find or right-click for the context menu.
2. In the Find What box, enter the text that you want to search for.
3. Select any other options that you want.
4. Click Find Next.

To cancel a search in progress, press Esc or select the Cancel button.
Caution: Although it is possible to edit XML source code directly in the XML Source tab, it is
recommended that you do not make any changes unless you are familiar with the Adobe XML
Forms Architecture. For more information about the XML Forms Architecture, see
www.adobe.com/devnet/livecycle/.
To replace text or other items
You can automatically replace text. For example, you can replace Corp. with Corporation.
1. In the Script Editor, select Edit > Replace.
2. In the Find What box, enter the text that you want to search for.
3. In the Replace With box, enter the replacement text.
4. Select any other options that you want.
5. Click Find Next, Replace, or Replace All.
6. To cancel a search in progress, press Esc or select the Cancel button.
To replace text that appears in scripts attached to multiple objects on your form, select the root subform of
your form (by default: form1) and select Show Events for Child Objects and then perform the
procedure above.
Caution: Although it is possible to edit XML source code directly in the XML Source tab, it is
recommended that you do not make any changes unless you are familiar with the Adobe XML
Forms Architecture. For more information about the XML Forms Architecture, see
www.adobe.com/devnet/livecycle/.
To use statement completion to create calculations and scripts
The statement completion functionality within the Script Editor lets you build your calculations and scripts
interactively.
When writing a calculation or script, each time you enter a period (.) immediately following a form object
or property name, the statement completion functionality displays a list of available methods and
properties. If the statement completion list does not appear, verify that you have typed the object or
property name correctly and that the object is within the scope of the object where you are creating your
script. For more information about referencing objects in calculations and scripts, see “Referencing
Objects in Calculations and Scripts” on page 56.
Adobe LiveCycle Designer Creating Calculations and Scripts
LiveCycle Designer Scripting Basics To insert object reference syntax automatically 20
1. Type the name of a form design object, property, or a valid FormCalc shortcut, followed by a period.
2. Select the method or property you want to apply for the form design object and continue writing the
script. To close the statement completion list without selecting a function, press the Esc key.
The list of available XML Form Object Model properties changes depending on the form design object or
property that appears before the period.
Note: The statement completion list appears only when accessing objects, properties, and methods in the
XML Form Object Model. It does not appear when working with standard JavaScript objects or
methods.
To insert object reference syntax automatically
As an alternative to using the statement completion list to create object reference syntax, you can use the
insert object reference syntax feature to automatically add reference syntax to your calculation or script.
This feature inputs an abbreviated reference syntax for the object you select from the canvas into the
Script Source field of the Script Editor. This reduces the time required to create calculations and scripts and
ensures that the reference syntax is accurate.
1. Ensure that the Script Source field of the Script Editor has the focus and the cursor is positioned where
you want to insert the object reference.
2. On your form, Ctrl+click the object you want to reference. The cursor changes to to assist you when
selecting an object.
Determining when to run your calculation or script
When creating calculations and scripts, you must associate each entry with a specific form event. Each
form event represents a change in the form’s state that initiates at a specific time. The change in form state
can occur during form rendering on the server by LiveCycle Forms, or on the client by Acrobat or
Adobe Reader while a user is filling a form. When a change in the state of the form occurs, any calculations
or scripts associated with the event are processed automatically.
The event you use when creating a calculation or script will, to some extent, determine what you must
include in your calculation or script. For example, the amount and type of information available on a form
may be different depending on the event timing you choose; therefore, a calculation or script that
Adobe LiveCycle Designer Creating Calculations and Scripts
LiveCycle Designer Scripting Basics To view scripting events and scripts 21
retrieves a value from a field may have different results if run before instead of after a form filler performs
certain actions. For more information about events, see “Events” on page 24.
Depending on the type of form you are creating, some events may never occur. For example, if you are
creating a form that has a fixed layout and no interactive objects, then interactive events associated with
form filler actions may never occur and, as a result, any scripts associated with those events will not run.
Although LiveCycle Designer includes support for a wide variety of form events, it is possible to
accomplish a wide variety of common calculation and scripting tasks by using only a few events that occur
at major changes in a form’s state, such as the following events:
●docReady ●Initiates immediately after the form opens in Acrobat or Adobe Reader® and immediately
before the form filler can begin interacting with form objects. This event is the last event to occur
before control of the form is given to the form filler.
●enter ●Initiates when the form filler changes the focus to a particular field, button, or subform.
●exit ●Initiates when the form filler changes the focus from a particular field, button, or subform, to
another object.
●change ●Initiates when a form filler makes a change to a field value. This event is most commonly
used with drop-down lists or list boxes to execute a script when a form filler makes a change to the
current value.
●click ●Initiates when a form filler clicks a field or button. This event is most commonly used with
buttons to execute a script when a form filler clicks the button.
To view scripting events and scripts
The Script Editor, provides several ways to view scripting events for objects in your form, depending on the
type of object or objects you select, and the quantity of events you want to display.
Before you begin, you must perform the following actions:
●If the Script Editor is not displayed on the screen, select Window > Script Editor.
●If the Script Editor is not large enough to display more than one line of script at a time, drag its lower
line down to increase its size.
➤To view a scripting event for a single object in the Script Editor
1. Select an object in your form.
2. In the Show list, select a valid scripting event.
➤To view a scripting event for a container object and its children in the Script Editor
1. If it is not already in multiline mode, expand the Script Editor to display multiple lines of script and
ensure that the Show Events for Child Objects option is selected.
2. Select a container object, such as a subform.
3. In the Show list, select a valid scripting event.
The events appear in the script editing field of the Script Editor, separated by the reference syntax for each
event. Note that certain events only apply to specific types of objects. When you select a script event, the
script editing field of the Script Editor only displays valid instances of the event. For example, if you select a
subform that contains a drop-down list and select the preOpen event, the Script editor displays a single

LiveCycle Designer Scripting Basics To view scripting events and scripts 22
entry representing the drop-down list. This is because the preOpen event only applies to drop-down lists.
Alternatively, selecting the enter event displays two entries, one for the drop-down list and one for the
subform.
Note: The Show list denotes events that contain scripts using a trailing asterisk (*) after the name of the
event. If an event contains a script, when you select the event from the Show list, the source appears
in the script editing field of the Script Editor.

Adobe LiveCycle Designer Creating Calculations and Scripts
LiveCycle Designer Scripting Basics Determining where to run your calculation or script 23
Determining where to run your calculation or script
For each calculation and script created in LiveCycle Designer, you must specify the location where you
want the calculation or script to run.
Unless you are using server-based processing such as LiveCycle Forms, you should ensure that all of your
calculations and scripts are set to run on the client application (for example, on Acrobat or a web browser).
Note: FormCalc calculations and scripts do not work on forms rendered as HTML and are ignored during
form filling.
If you are using server-based processing, you can choose between running calculations on the client
application, or running them on the server. By choosing to have calculations and scripts run on the server,
you are choosing to run the scripts at a specific point during the form-rendering process.
If you choose Client And Server from the Run At list, your calculation or script is available to both client and
server-based applications. This option is useful, for example, if you do not know whether your users will
have client or server applications when they attempt to use your form. It is also useful if you want certain
form objects to behave one way to a client application and another to a server-based application.
Testing and debugging calculations and scripts
After you have created your calculation or script and tested your form, you may discover scripting errors or
other unexpected field values as a result of scripting errors.
LiveCycle Designer includes three primary methods for testing and debugging your calculations and
scripts:
●Using the LiveCycle Designer workspace palettes. For more information, see “Using the workspace to
debug calculations and scripts” on page 14.
●For JavaScript only, using the JavaScript Debugger to assist you in testing your scripts. For more
information on using the debugger, see “To enable the JavaScript Debugger for LiveCycle Designer” on
page 68.
●Using the host model and event model properties and methods to troubleshoot your form.
The host model and event model provide functionality that lets you interact with either the host
application or the various form events. These models are useful for returning information that can assist
you in debugging calculation and scripts.
For example, the following script returns a message at run time indicating the name of the event on which
the script is placed. This indicates that a particular event has fired:
xfa.host.messageBox(xfa.event.name) // FormCalc
xfa.host.messageBox(xfa.event.name); // JavaScript
Another example of using the host model and event model methods is to obtain the value of a field on an
interactive form before a user manually changed it. This is useful for observing how the objects on your
form design respond to user-entered data:
xfa.host.messageBox(xfa.event.prevText) // FormCalc
xfa.host.messageBox(xfa.event.prevText); // JavaScript
24
4Events
About events
Every calculation or script you attach to a form object is associated with a specific event. An event is
defined as a particular occurrence or action that can change the state of a form and, when the change of
state occurs, automatically invoke a calculation or script associated with the event. Events occur at various
times, from the beginning of the form rendering process when merging data with a form design, all the
way through to a form filler interacting with objects on a form in a client application. By applying
calculations and scripts to specific events, you can control every aspect of how you present form objects,
as well as form data, and how the objects and data respond to form filler interaction.
A single change of state or form filler action may trigger multiple events. For example, tabbing from the
current field to the next field triggers both the exit event for the current field and the enter event for
the next field. If the current and next fields are in different subforms, a total of four events are triggered;
namely, exit events for the current field and subform, and enter events for the next field and subform.
In general, each of the different categories of form events follow a predictable ordering.
Types of events
Form events fall into one of the following categories:
Process events This type of event initiates automatically as the result of an internal process or action
related to objects on a form. For example, if a form filler clicks a button that adds a new page to the form,
the initialize, calculate, validate, and layout:ready process events initiate automatically for
the new page.
Interactive events This type of event initiates as a direct result of form filler actions. For example, if a form
filler moves the pointer over a field on a form, the mouseEnter event initiates in response to the action.
Application events This type of event initiates as a result of the actions that either a client application or
a server application performs. For example, you can create a calculation or script to perform a task
immediately after the form is saved by using the postPrint event.
Process events
Process events initiate automatically as the result of an internal process or action related to a form or
objects on a form. These events initiate immediately following significant form changes; for example, after
a form design is merged with data or after the form pagination process finishes. Process events also initiate
immediately after interactive events initiate. For example, immediately after any interactive event initiates,
the calculate event initiates followed by the validate event.
The following list contains the process events, which are available from the Show list in the Script Editor:
●calculate
●form:ready
●indexChange
Adobe LiveCycle Designer Events
LiveCycle Designer Scripting Basics Interactive events 25
●initialize
●layout:ready
●validate
Process events can initiate many times as a result of dependencies; that is, actions associated with a single
event that ultimately initiates one or more additional events. Using an example of a form filler clicking a
button to reveal a previously hidden portion of the form, after the form filler clicks the button, not only
does a series of interactive and processing events initiate for the button itself, but a number of process
events for the new subform initiates as well.
The following image represents the general flow of events leading up to a PDF form opening in Acrobat or
Adobe Reader.
After the form opens in Acrobat or Adobe Reader, these process events may still initiate as the result of
changes made to the form. For example, the calculate, validate, and layout:ready events for an
object initiate immediately after some interactive events occur; therefore, calculations and scripts
attached to the processing events will run multiple times.
Interactive events
Interactive events initiate as a direct result of form filler actions, which makes these events useful for a
variety of calculation and scripting tasks. For example, you can add a script to the mouseEnter event for a
text field that changes the border color of the field to blue and a script to the mouseExit event that
changes the border color back to the original color. This action creates a highlighting effect when form
fillers move the pointer over the field to visually assist them while filling the form. Interactive events are
also useful for changing form data in response to a form filler selection. For example, you can add a script
to the change event for a drop-down list that updates the data values in multiple fields in response to the
value the form filler selects in the drop-down list.
Adobe LiveCycle Designer Events

The following image displays the general flow of events for form fillers who use the mouse to select an
object and change its value.
Note: This image provides a general flow of events; however, certain form filler actions and form objects
can cause alternate event ordering. For example, if a form filler selects a value from a drop-down list,
the mouseExit event occur after the click event but before the change or full events.
Similarly, if a form filler selects a field, holds down the mouse, and then exits the field while still
holding down the mouse button, the mouseUp event occurs out of the order described in this
image.
Adobe LiveCycle Designer Events
LiveCycle Designer Scripting Basics Application events 27
The following image displays the general flow of events for form fillers who use the keyboard to select an
object and change its value.
Application events
Application events initiate as a result of the actions that either a client application or a server application
performs, either in response to a form filler action or as a result of an automated process. For example, if a
form filler saves the form in Acrobat or Adobe Reader, the preSave event initiates immediately before the
save operation, followed by the calculate, validate, and layout:ready events, in order, for all
objects on the form. The same event sequence initiates if the form contains a script that programmatically
saves the form.
The following list contains the processing events, which are available from the Show list in the Script
Editor:
●docClose
●docReady
●postPrint
●postSave
●prePrint
●preSave
●preSubmit
Application events do not exist as part of a general flow of events. They are single events corresponding to
actions that the client or server application performs.
Adobe LiveCycle Designer Events
LiveCycle Designer Scripting Basics List of events 28
List of events
calculate event
Description
Initiates in the following situations:
●When your form design and data merge into your finished form.
●When a change occurs to any value that the calculation is dependent on, such as the value of a
particular field, unless the form filler has manually overridden the calculated value. As a result, the
object will display the return value of the event. The properties for manually overridden fields are
located in the Value tab of the Object palette.
●When a field loses focus; for example, when a form filler clicks or uses the Tab key to exit a field.
When using the calculate event to perform calculations or scripts, consider the following potential
issues:
●Calculations and scripts on the calculate event must not make any changes to the structure of the
form, except for the form field and data values.
●Content inserted by the calculate event must conform to the associated validations for the object;
otherwise, validation errors will occur.
●Calculations and scripts must not include an infinite loop because it causes the form to update the
value continuously. For example, a script that increments the value of a field as part of a looping
expression, such as a while or for loop, could create an infinite loop.
●The last expression evaluated in the calculate event is used to populate the value of the current
form object. For example, if the script on the calculate event first sets the value of the current field
to 500 and then sets the value of another field to 1000, both fields will display the value 1000 at run
time. As a result, you need to limit the scripting that you add to the calculate event to those that
deal specifically with setting the value of the current field.
Type
Processing event
Support
Example
Use the calculate event for updating numeric values in fields because this event initiates immediately
after most other events. For example, on a purchase order form, you can use the calculate event for a
field to determine the percentage of sales tax due based on the cost of the order. The calculation will
initiate every time a change is made to the values in the form fields, ensuring that the value displayed for
the sales tax is always correct.
However, because the calculate event can initiate many times, you must ensure that the calculation or
script you add to the event will not cause data values to increment unnecessarily. For example, if your sales

tax calculation adds the value of the sales tax to the total cost each time the calculate event initiates,
the resulting total cost value on your form may be too large.
For a detailed example of using the calculate event, see “Calculating the field sums” on page 103.
change event
Description
Initiates when a form filler changes the content of a field by performing one of these actions:
●Types a keystroke providing the field has keyboard focus
●Pastes data into the field
●Makes a selection from a list box or drop-down list
●Selects or deselects a check box
●Changes the setting of a group of radio buttons
This event does not initiate in response to changes in the object values as a result of calculations or scripts,
or by the merging of the form design with data.
Type
Interactive event
Support
Example
Use this event for any calculations or scripts that must initiate in response to a form filler changing the
value of a field. For example, you can use the change event for a drop-down list to highlight specific rows
in a table. Using this technique, each time the form filler selects a value in the drop-down list, the
corresponding row of the table appears highlighted.
For a detailed example of using the change event, see “Getting the current or previous value of a
drop-down list” on page 100.
click event
Description
Initiates when a mouse click occurs within the region. When a click event initiates for a text or numeric
field, calculations or scripts execute immediately. However, the value of the field does not change in
response to calculations and scripts until the field loses focus.

Note: You cannot place a calculation or script on the click event of a submit button because the
calculation or script will override the submission action. Instead, place any calculations and scripts
on the preSubmit event for a submit button.
For more information about form submission actions, see the LiveCycle Designer Help.
Type
Interactive event
Support
Example
Use this event for performing an action as a direct response to a form filler clicking a button or selecting a
radio button or check box on a form. For example, you can use the click event for a check box to hide
and show a field on the form.
For a detailed example of using the click event, see “Changing the visual properties of an object on the
client” on page 97.
docClose event
Description
Initiates at the very end of processing a form, only if all form validations complete with no errors.
Type
Application event
Support
Example
This event initiates too late to modify a saved form and is intended to provide the ability to generate an
exit status or completion message. For example, you can use the docClose event to display a message to
a form filler indicating that the form is completed.

docReady event
Description
Initiates immediately after the form opens in Acrobat or Adobe Reader.
Type
Application event
Support
Example
This event is the first one that initiates after the form opens in Acrobat or Adobe Reader. Any calculation or
scripting tasks that require the full form, or that should only run once when the form filler first opens the
form, should use this event. For example, you can use the docReady event to check the version of Acrobat
or Adobe Reader and return a message to the form filler if the form filler must upgrade the application
before filling the form.
enter event
Description
Initiates when a field or subform gains keyboard focus, whether caused by a form filler action (tabbing into
a field or clicking in it) or by a script programmatically setting the focus.
Type
Interactive event
Support
Example
You can use this event to provide help text or other messages to a form filler while entering the current
field or subform. For example, if a field requires a value in a specific format, or if filling a field requires
special instructions, you can use this event to provide a message to the form filler indicating the special
needs.

Note: This event is received only by the subform instances that are controlled by the instance manager;
the event is ignored for subform sets.
Type
Processing event
Support
Example
You can use this event to set properties based on the instance value of a particular object. For example,
you can use this event to coordinate the shading of alternate rows in a table.

initialize event
Description
Initiates for all objects after the form design is merged with data.
Type
Processing event
Support
Example
You can use this event to perform actions when an object is first created, either as the result of a form filler
action or during the form creation process. For example, you can use this event to control settings for new
instances of a subform object that a form filler adds to the form by using a button.
layout:ready event
Description
Initiates after the form design and data are merged, the form exists, and the form’s layout is applied. At this
time, the finished form has not been rendered; therefore, a calculation or script set to run on this event
could modify the layout before the forms is rendered. This event also occurs after the form is rendered if a
calculation or script changes the data or causes a change to the form in Acrobat or Adobe Reader.
Type
Processing event
Support
Example
You can use this event to perform tasks immediately after the form layout is established. For example, you
can use this event to determine the number of pages the form contains.

mouseDown event
Description
Initiates when a form filler presses the mouse button at the same time that the pointer is within a field.
Note: When a mouseDown event initiates for a text or numeric field, calculations or scripts run
immediately. However, the value of the field does not change in response to calculations and scripts
until the field loses focus. When a mouseDown event initiates for a document signature field, the
event initiates before the signature process begins.
Type
Interactive event
Support
Example
You can use this event to perform an action as a direct response to a form filler clicking a button, or
selecting a radio button or check box on a form. For example, you can use the mouseDown event for a
check box to hide and show a field on the form. This event is conceptually similar to the click event and
has a similar purpose.
mouseEnter event
Description
Initiates when the form filler moves the pointer into the area of the field, without necessarily pressing the
mouse button. This event is not initiated when the pointer moves into the field for a different reason; for
example, because an overlapping window closes.
Type
Interactive event
Support
Example
You can use this event to provide visual feedback to a form filler in conjunction with the mouseExit
event. For example, you can use this event to change the border or background color of an object to help
visually indicate to form fillers that they are working in a specific field.
For a detailed example of using the mouseEnter event, see “Highlighting fields in response to form filler
interaction” on page 104.

mouseExit event
Description
Initiates when a form filler moves the pointer out of the field, even if the form filler is pressing the mouse
button. It is not initiated when the pointer moves out of the field for a different reason; for example,
because an overlapping window opens.
Type
Interactive event
Support
Example
You can use this event to provide visual feedback to a form filler in conjunction with the mouseEnter
event. For example, you can use this event to return the border or background color of an object to its
original value to help visually indicate to form fillers that they are no longer working in a specific field.
For a detailed example of using the mouseExit event, see “Highlighting fields in response to form filler
interaction” on page 104.
mouseUp event
Description
Initiates when a form filler releases the mouse button at the same time that the pointer is within a field.
Note: When a mouseUp event occurs for a text or numeric field, calculations or scripts run immediately.
However, the value of the field does not change in response to calculations and scripts until the
field loses focus.

postPrint event
Description
Initiates immediately after the rendered form is sent to the printer, spooler, or output destination.
Type
Application event
Support
Example
You can use this event to display information messages to the form filler after the form is printed. For
example, you can create a script on the postPrint event to remind form fillers what steps they need to
take to submit the form by hand.
postSave event
Description
Initiates immediately after a form filler saves a form in PDF or XDP format. This event does not initiate
when you export a subset of the form (for example, only form data) to XDP.
Type
Application event
Support
Example
You can use this event to display information messages to the form filler after the form data is saved. For
example, you can create a script on the postSave event to remind form fillers how much time remains for
them to successfully complete and submit the form.
preOpen event
Description
Initiates when a form filler performs an action that causes the drop-down list to appear, such as clicking
the arrow icon on the drop-down list or by tabbing into the drop-down list and using the down arrow. This
event initiates before the contents of the drop-down list are displayed.

event to load a fixed number of records from a data source into a drop-down list. This improves the
performance of the form for the form filler at run time.
prePrint event
Description
Initiates immediately before the process of rendering a form for printing begins. You cannot cancel
printing using this event.
Caution: Avoid using this event to hide or show form objects. For example, if a form filler has already
digitally signed the form, using this event to hide all button objects prior to printing will impact
the state of the signature.

Example
You can use this event to change form data immediately before the data is saved. For example, you can
create a script on the preSave event to scan the data and display a reminder message to the form filler if
certain required fields remain empty.
preSubmit event
Description
Initiates when a form submits data to the host through the HTTP protocol. At this point, the data is
organized into a data set but has not been sent to the host. Calculations and scripts associated with this
event can examine and alter the data prior to the form submission. If the calculation or script is set to run
on the server, the form sends the data to the server indicating that it should run the calculation or script
before performing any additional processing.
Note: This event does not distinguish between submissions initiated by instances of clicking buttons or to
different URLs. Any script that needs to make these distinctions must include code to determine
which button was clicked. In general, the preSubmit event is conceptually similar to the preSave
event and serves a similar purpose.
Type
Application event
Support
Example
You can use this event to change form data immediately before the data is submitted. For example, you
can create a script on the preSubmit event to scan the amount of data and display a message to the form
filler estimating how long the data submission may take.

validate event
Description
Initiates when the form design and data merge to create your form and when a field loses focus; for
example, when a form filler clicks or uses the Tab key to exit a field. This event initiates again each time the
value of a field changes. Calculations and scripts placed on the validate event provide a method to
perform validations that are more specific than those available through the Value tab of the Object
palette.
Calculations and scripts on the validate event are required to return true or false (expressed in a
format appropriate to the scripting language) corresponding to a validation that succeeds or fails, and
must not affect the overall form structure of form values. In addition, calculations and scripts should not
attempt to provide feedback to a form filler because that form filler may not be using the form in a client
application such as Acrobat.
Note: Because validations are performed against the content of the form, they cannot be used to verify
presentation formatting caused by field patterns.
Type
Processing event
Support
Example
You can use this event to verify object values, particularly in situations where object data must conform to
specific rules. For example, you can create a script on the validate event to verify that a total cost field
on a purchase order form does not have a negative value.
For a detailed example of using the validate event, see “Setting a field as required at run time” on
page 102.

Using FormCalc
About using FormCalc
FormCalc is a simple yet powerful calculation language modeled on common spreadsheet software. Its
purpose is to facilitate fast and efficient form design without requiring a knowledge of traditional scripting
techniques or languages. With the use of a few of the built-in functions, users new to FormCalc can expect
to quickly create forms that save end users from performing time-consuming calculations, validations, and
other verifications. In this manner you can create a basic set of rules for the form design that allows the
resulting form to react according to the data it comes into contact with.
Within LiveCycle Designer, FormCalc is the default scripting language in all scripting locations with
JavaScript as the alternative. For information on setting your default scripting language, see “About the
Script Editor” on page 11.
Caution: If you are developing forms for use with a server-based process (for example, using
LiveCycle Forms), with the intent of rendering your forms in HTML, you should develop your
calculations and scripts in JavaScript. FormCalc calculations are not valid in HTML browsers, and
are removed prior to the form being rendered in HTML.
FormCalc treats each new line in the Script Editor as a new expression to evaluate.
Using built-in functions
The built-in functions that make up FormCalc cover a wide range of areas, including mathematics, dates
and times, strings, finance, logic, and the web. These areas represent the types of functionality that
typically occur in forms, and the purpose of the functions is to provide quick and easy manipulation of
form data in a useful way.
At the most basic level, a calculation can consist of only a single FormCalc function. However, a single
FormCalc function can make use of other FormCalc functions as parameters.
Upper(s1 [, k1 ] ) Converts all lowercase
characters within a string
to uppercase.
String.toUpperCase()
Uuid(n1)Returns a Universally
Unique Identifier (UUID)
string to use as an
identification method.
None
Within(s1, s2, s3)Returns true (1) if the test
value is within a given
range, and false (0) if it is
not.
String.search(s1)
WordNum(n1 [, n2 [, k1 ] ] ) Returns the English text
equivalent of a given
number.
None

Adobe LiveCycle Designer Scripting Languages
LiveCycle Designer Scripting Basics Using FormCalc 48
To attach a FormCalc function to an object
You can add a FormCalc function to any form design object that allows calculations and scripts, with the
exception of the script object.
1. Make sure that you have the multiline version of the Script Editor showing on the LiveCycle Designer
workspace.
2. Select a field on your form.
3. In the Show list, select the calculate event.
4. Click Functions or F10 to display a list of FormCalc functions.
5. Select the desired function and press Enter.
6. Replace the default function syntax notation with your own set of values.
7. Click Enter Script Source Changes to add the FormCalc calculation to your form.
Built-in function syntax
Each FormCalc function uses a specific syntax notation that you must follow in order for the function to
execute correctly. The table below describes, very generally, the pieces of syntax notation.
For more information and examples of valid syntax notation values, see the appropriate FormCalc
functions in the LiveCycle Designer Help.
Syntax Notation Replacement Values
dA valid date string (for example, 03/15/1996)
fA valid date format string (for example, MM/DD/YYYY)
kA valid locale identifier (for example, fr_FR)
nA valid numeric value. Note that the range of valid values varies from
function to function.
sA valid unit of measurement (for example, “in” for inches).
vA valid reference syntax.
n1, n2, n3 All values are required.
[ [ n [, k ] ] ] No values are required, but you can choose to specify just n, or both n and k.
n1 [, n2 ... ] n1 is required, but you can choose to specify an unlimited number of
additional values.
d [, f [, k ] ] d is required, but you can choose to also specify f or both f and k.

LiveCycle Designer Scripting Basics Using FormCalc 49
Creating basic calculations
About basic calculations
Simple expressions are the most basic instances of scripting. These expressions do not involve using
FormCalc built-in functions and are never more than a single line in size. You must add simple expressions
to the calculate event of a particular field or object in order for the value of the expression to output onto
your form.
Examples of basic calculations
These are all examples of simple expressions:
2
"abc"
2 - 3 * 10 / 2 + 7
Each simple expression evaluates to a single value by following a traditional order of operations, even if
that order is not always obvious from the expression syntax. For example, the following sets of expressions
produce equivalent results:
As implied in the previous table, all FormCalc operators carry a certain precedence when they appear
within expressions. The following table illustrates this operator hierarchy.
Expression Equivalent to Result
"abc" "abc" abc
2 - 3 * 10 / 2 + 7 2 - (3 * 10 / 2) + 7 -6
(10 + 2) * (5 + 4) (10 + 2) * (5 + 4) 108
0 and 1 or 2 > 1 (0 and 1) or (2 >1) 1 (true)
2 < 3 not 1 == 1 (2 < 3) not (1 == 1) 0 (false)
Precedence Operator

Lowest | , or
Adobe LiveCycle Designer Scripting Languages
LiveCycle Designer Scripting Basics Using FormCalc 50
All of the previous examples are valid, simple expressions that you can add to a form field or object that
will accept calculations and scripts. For example, if you create a new form in LiveCycle Designer with a
single numeric field, add the following calculation to the calculate event in the Script Editor.
Then, when you click the Preview tab to view the completed form, the value of the simple expression
appears in the text field.
If the value does not appear in the preview, ensure that your simple expression appears in the calculate
event of the form design object. You need to also ensure that you installed LiveCycle Designer and Acrobat
correctly.

LiveCycle Designer Scripting Basics Using JavaScript 51
Using JavaScript
About using JavaScript
To allow form designers more flexibility and scripting power, LiveCycle Designer supports the use of
JavaScript version 1.6 or earlier in all situations that support scripting.
Form developers familiar with JavaScript will be able to take their existing expertise and apply it directly to
LiveCycle Designer. LiveCycle Designer provides a number of properties and methods that enhance
JavaScript to allow you to access field and object values. These properties and methods combine with the
LiveCycle Designer reference syntax to provide you with easy manipulation of form values and data.
Note: The Script Editor does not provide syntax error checking for scripts created using JavaScript. In
addition, statement completion options do not appear for standard JavaScript objects or methods.
Creating scripts using JavaScript
Creating scripts in LiveCycle Designer using JavaScript is very similar to creating JavaScript in other
applications. You can take advantage of previous knowledge of JavaScript concepts, reuse JavaScript
functions using the LiveCycle Designer script object, and take advantage of JavaScript language
functionality.
However, it is important to note that while previous JavaScript knowledge is transferable, to effectively use
JavaScript on your form design you must understand how to construct LiveCycle Designer reference
syntax. Specifically, you must be able to correctly use the XML Form Object Model reference syntax to
access objects on your form design.
The following table outlines the key concepts for developing scripts in JavaScript for LiveCycle Designer,
as well as where to find more information on each concept within the LiveCycle Designer Help.
In addition to the resources available in the LiveCycle Designer Help, the LiveCycle Developer Center
contains extensive scripting resources and documentation. The developer center is located at
www.adobe.com/devnet/livecycle/.

LiveCycle Designer Scripting Basics Using JavaScript 52
To attach a JavaScript script to an object
You can add a JavaScript script to any form design object that allows calculations and scripts, including the
script object.
1. Make sure that you have the multiline version of the Script Editor showing on the LiveCycle Designer
workspace.
2. Select a field on your form. For example, add a new text field to your form design.
3. In the Show list, select a valid event. For example, using the new text field, select the docReady event.
4. In the Run At list, select where you want the script to execute. For example, for the new text field, select
Client.
5. Click Functions or F10 to display a list of JavaScript functions, select the desired function, and press
Enter. Replace the default function syntax notation with your own set of values. Alternatively, you can
create your own script manually in the Script Source field of the Script Editor. For example, in the new
text field, add the following JavaScript to the Script Source field:
this.border.fill.color.value = "255,0,0";
6. Click Enter Script Source Changes to add the JavaScript script to your form.
7. Test the script by previewing the form using the Preview PDF tab. For example, for the new button
object, when the form is displayed in the Preview PDF tab, the text field should appear red.

6Variables
About variables
You can define form variables in LiveCycle Designer to store specific information in a central, accessible
location. A variable typically acts as a placeholder for text that you might have to change in the future. For
example, a variable can store the text of a message box title. When the text needs to change, all you have
to do is open the affected form or template and update the text once through the variable definition.
LiveCycle Designer automatically propagates the new text across all instances of the inserted variable.
Keep in mind that form variables are defined outside of the Script Editor, and are accessible by scripts on
all objects on a form, as opposed to scripting variables that you create in a specific FormCalc or JavaScript
script.
You can create, view, and delete variables without using scripting. However, you must use scripting to
access the values stored by variables and manipulate them, or to apply the values to objects on your form.
Note: Form variable values reset each time you open a form.
Before you create a variable, decide the name of the variable and the text that it will contain. Variable
definitions are saved with the form or template.
Naming variables
At run time, naming conflicts occur when the names of variables are identical to those used as XML Form
Object Model properties, methods, or form design field names. These conflicts can cause scripts to return
unexpected values; therefore, it is important to give each variable a unique name. Here a couple of
examples:
●Use the variable name fieldWidth and fieldHeight instead of x and y.
●Use the form design object name clientName instead of name.
Note: Variable names are case-sensitive and should not contain spaces.
To define a text variable
1. Select File > Form Properties.
2. In the Variables tab, click New (Insert) .
3. In the Variables list, type a unique name for the variable and press Enter. Variable names are
case-sensitive and should not contain spaces.
4. Click once in the box to the right and type the text you want to associate with the variable.

The variable appears in the Hierarchy palette at the form level.
To view a text variable definition
1. Select File > Form Properties.
2. Click the Variables tab and select the variable from the Variables list. The associated text is displayed in
the box to the right.
To delete a text variable
1. Select File > Form Properties.
2. In the Variables tab, select the variable and click Delete (Delete) .
Using variables in calculations and scripts
After you have created form variables, you only need to reference the variable name in your calculations
and scripts in order to obtain the value of the variable.
Caution: When naming variables, you should avoid using names that are identical to the names of any
XML Form Object Model properties, methods, or object names. For information about XML Form
Object Model properties, methods, and objects, see the Adobe XML Form Object Model Reference
at www.adobe.com/devnet/livecycle/designing_forms.html.
For example, create the following form variable definitions.
New form variable
Variable name Value
firstName Tony
lastName Blue
age 32
Adobe LiveCycle Designer Variables
LiveCycle Designer Scripting Basics Using variables in calculations and scripts 55
In FormCalc, you can access the variable values in the same manner that you access field and object values.
In this example, the values are assigned to three separate fields:
TextField1 = firstName
TextField2 = lastName
NumericField1 = age
You can also use variables in FormCalc functions in the same way, as shown in this example:
Concat( "Dear ", firstName, lastName )
In JavaScript, you reference variable values by using the .value property instead of the .rawValue
property that is used for field and object values, as shown in this example:
TextField1.rawValue = firstName.value;

7Referencing Objects in Calculations and Scripts
About referencing objects in calculations and scripts
Although both FormCalc calculations and JavaScript scripts have rules for structuring code, both rely on
the same reference syntax when accessing form object properties and values. The XML Form Object Model
provides a structured way to access object properties and values through a compound naming
convention with each object, property, and method separated by dot (.) characters.
In general, each reference syntax has a similar structure divided into the following sections:
●The names of the parent objects in the form hierarchy that is used to navigate to a specific field or
object. You can use the Hierarchy palette and Data View palette to determine the location of an object
relative to other objects in the form and in any associated data.
●The name of the object you want to reference.
●The the name of the property or method you want to access. This section may also include XML Form
Object Model objects that precede the property or method in the structure but that do not appear as
objects in the Hierarchy palette.
For example, the following illustration shows the reference syntax for accessing the value of a text field on
a form design that uses the default object-naming conventions:
Note: By default, the subform object that represents the first page of a new form is unnamed. In the
reference syntax above, the unnamed subform is represented by #subform.
The reference syntax notation structure varies slightly, depending on the specific situation. For example, a
fully qualified reference syntax works in any situation; however, in some cases, you can use a shortened
reference syntax or a reference syntax shortcut to reduce the size of the syntax.
Referencing object properties and values
The reference syntax you use to access or modify object properties and values takes one of the following
forms:
Fully qualified Reference syntax includes the full object hierarchy, beginning with the xfa root node.
The fully qualified syntax accurately accesses the property or value of an object regardless of where the
calculation or script that contains the reference syntax is located.
xfa.form.form1.#subform.TextField1.rawValue
Property or
method name
Form hierarchy
objects
Object name
Adobe LiveCycle Designer Referencing Objects in Calculations and Scripts
LiveCycle Designer Scripting Basics Referencing object properties and values 57
Abbreviated The reference syntax is shortened either because of the relative positioning of the
calculation or script that contains the reference syntax and the object syntax references, or because
shortcuts are used. In general, although an abbreviated reference syntax is faster to create, the
disadvantage is that it works only as long as the objects remain in the same positions relative to each
other.
For example, this illustration shows the hierarchy of a sample purchase order form.
This illustration shows a fully qualified reference syntax, for both FormCalc and JavaScript, to access the
value of the txtCondition field. This reference syntax could be used as part of a calculation or script on
any object on the form.
xfa.form.form1.purchaseOrder.total.txtCondition.rawValue
Root Node
Model
Property or
method name
Form design
root node
Page object
Object name
Subform name
Adobe LiveCycle Designer Referencing Objects in Calculations and Scripts
LiveCycle Designer Scripting Basics Referencing unnamed and repeated objects 58
Note: Even though the reference syntax is common to both FormCalc and JavaScript, you must observe
the conventions for each scripting language. For example, the reference syntax in the example
above works as is for FormCalc; however, you would need to include a trailing semicolon (;)
character for JavaScript.
If two objects exist in the same container, such as a subform, they are referred to as sharing the same
context. Where objects exist in the same context, you can use an abbreviated reference syntax that
includes only the name of the object followed by the property or method you want to access. For example,
using the example from above, the following abbreviated reference syntax accesses the value of the
txtCondition field from any of the fields in the total subform:
txtCondition.rawValue
If two objects exist in different containers, they do not share the same context. In this case, you can use an
abbreviated reference syntax; however, the syntax must begin with the name of the highest level
container object that the two objects do not have in common. For example, using the hierarchy above, the
following abbreviated reference syntax accesses the value of the address field from the txtCondition
field:
header.address.rawValue
Due to the way the XML Form Object Model is structured, some object properties and methods exist on
child objects of the objects on the form. These child objects exist only as part of the XML Form Object
Model and do not appear in the Hierarchy and Data View palettes. To access these properties and
methods, you must include the child objects in the reference syntax. For example, the following reference
syntax sets the tool tip text for the txtCondition field:
txtCondition.assist.toolTip.value = "Conditions of purchase." // FormCalc
txtCondition.assist.toolTip.value = "Conditions of purchase."; // JavaScript
For more information about the XML Form Object model objects and their structure, see the Adobe XML
Form Object Model Reference at www.adobe.com/devnet/livecycle/designing_forms.html.
Referencing unnamed and repeated objects
LiveCycle Designer supports the capability to create both unnamed objects and multiple objects with the
same name. You can still create calculations and scripts to access and modify properties and values of
unnamed objects by using the number sign (#) notation and object occurrence values using the square
bracket ([ ]) notation. FormCalc correctly interprets the number sign (#) and square bracket ([ ])
characters; however, JavaScript does not. To access the value of a text field in a situation where the
number sign (#) or square brackets ([ ]) occur, using JavaScript, you must use the resolveNode method
in conjunction with either a fully qualified reference syntax or an abbreviated reference syntax.
Adobe LiveCycle Designer Referencing Objects in Calculations and Scripts
LiveCycle Designer Scripting Basics Referencing unnamed and repeated objects 59
For example, when you create a new blank form, by default, the name of the subform that represents the
page of the form is an unnamed subform with an occurrence value of 0. The following illustration shows
the form hierarchy on a new form with default object naming.
The untitled subform that represents the first page of the form has an occurrence number of 0. In this
situation, both of the following reference syntaxes access the value of the text field in the form hierarchy
above on a new form that uses default naming conditions:
xfa.form.form1.#subform.TextField1.rawValue
xfa.form.form1.#subform[0].TextField1.rawValue
Note: By default, if you do not specify an occurrence value for an object, the reference syntax accesses the
first occurrence of that object.
FormCalc recognizes the fully qualified reference syntax above and interprets it directly. To access the
same value by using JavaScript, you must use one of these forms of the resolveNode scripting method:
xfa.resolveNode("xfa.form.form1.#subform.TextField1").rawValue;
xfa.resolveNode("xfa.form.form1.#subform[0].TextField1").rawValue;
If you add a new page to your form, by default, the name of the subform that represents the new page is
unnamed; however, the occurrence value for the new subform is set to 1. You can specify the new
unnamed subform by using a similar reference syntax as above:
xfa.form.form1.#subform[1].TextField1.rawValue // FormCalc
xfa.resolveNode("xfa.form.form1.#subform[1].TextField1").rawValue; // JavaScript
Note: The statement completion options available in the Script Editor include unnamed objects at the
beginning of the list. Objects that have multiple occurrence values appear only once in the list,
representing the first occurrence of the object. If you want to access an occurrence value other that
the first occurrence, you must manually add the occurrence value to the reference syntax.
You can use the resolveNode method to reference objects within other reference syntax statements.
This can help to reduce the amount of scripting you need to reference a particular object, property, or
method. For example, you could simplify the reference syntax that points to a text field on the second
page of your form to the following statement:
xfa.form.form1.resolveNode("#subform[1].TextField1").rawValue; // JavaScript
Adobe LiveCycle Designer Referencing Objects in Calculations and Scripts
LiveCycle Designer Scripting Basics Referencing the current object 60
Referencing the current object
If you want to change properties or values of the current object using calculations or scripts attached to
the object itself, both FormCalc and JavaScript use unique shortcuts to reduce the size of the reference
syntax. FormCalc uses the number sign ($) character to denote the current object, and JavaScript uses the
keyword this.
For example, the following reference syntax returns the value of the current object:
$ // FormCalc
this.rawValue // JavaScript
Similarly, you can use the dollar sign ($) shortcut and the keyword this to replace the name of the current
object when accessing object properties in calculations and scripts. For example, the following reference
syntax changes the tool tip text associated with the current object:
$.assist.toolTip.value = "This is some tool tip text." // FormCalc
this.assist.toolTip.value = "This is some tool tip text."; // JavaScript
FormCalc reference syntax shortcuts
To make accessing object properties and values easier, FormCalc includes shortcuts to reduce the effort
required to create references. The following table outlines the reference syntax shortcuts for FormCalc.
Notation Description
$Refers to the current field or object, as shown in this example:
$ = "Tony Blue"
The above example sets the value of the current field or object to Tony Blue.
$data Represents the root of the data model xfa.datasets.data. For example,
$data.purchaseOrder.total
is equivalent to
xfa.datasets.data.purchaseOrder.total
$event Represents the current form object event. For example,
$event.name
is equivalent to
xfa.event.name
$form Represents the root of the form model xfa.form. For example,
$form.purchaseOrder.tax
is equivalent to stating
xfa.form.purchaseOrder.tax
$host Represents the host object. For example,
$host.messageBox("Hello world")
is equivalent to
xfa.host.messageBox("Hello world")
Adobe LiveCycle Designer Referencing Objects in Calculations and Scripts
LiveCycle Designer Scripting Basics FormCalc reference syntax shortcuts 61
$layout Represents the root of the layout model xfa.layout. For example,
$layout.ready
is equivalent to stating
xfa.layout.ready
$record Represents the current record of a collection of data, such as from an XML file. For
example,
$record.header.txtOrderedByCity
references the txtOrderedByCity node within the header node of the current
XML data.
$template Represents the root of the template model xfa.template. For example,
$template.purchaseOrder.item
is equivalent to
xfa.template.purchaseOrder.item
! Represents the root of the data model xfa.datasets. For example,
!data
is equivalent to
xfa.datasets.data
*Selects all form objects within a given container, such as a subform, regardless of
name, or selects all objects that have a similar name.
For example, the following expression selects all objects named item on a form:
xfa.form.form1.item[*]
Note: You can use the ‘*’ (asterisk) syntax with JavaScript if it used with the
resolveNode method. For more information about the resolveNode
method, see the LiveCycle Designer Help or the Adobe XML Form Object Model
Reference.
Notation Description
Adobe LiveCycle Designer Referencing Objects in Calculations and Scripts
LiveCycle Designer Scripting Basics FormCalc reference syntax shortcuts 62
.. You can use two dots at any point in your reference syntax to search for objects that
are a part of any subcontainer of the current container object, such as a subform. For
example, the expression Subform_Page..Subform2 means locate the node
Subform_Page (as usual) and find a descendant of Subform_Page called
Subform2.
Using the example tree above,
Subform_Page..TextField2
is equivalent to
Subform_Page.Subform1[0].Subform3.TextField2[0]
because TextField2[0] is in the first Subform1 node that FormCalc encounters
on its search. As a second example,
Subform_Page..Subform3[*]
returns all four instances of the TextField2 object.
Note: You can use the ‘..’ (double period) syntax with JavaScript if it used with the
resolveNode method. For more information about the resolveNode
method, see the LiveCycle Designer Help or the Adobe XML Form Object Model
Reference.
#The number sign (#) notation is used to denote one of the following items in a
reference syntax:
●An unnamed object. For example, the following reference syntax accesses an
unnamed subform:
xfa.form.form1.#subform
●Specify a property in a reference syntax if a property and an object have the same
name. For example, the following reference syntax accesses the name property of
a subform if the subform also contains a field named name:
xfa.form.form1.#subform.#name
Note: You can use the ‘#’ (number sign) syntax with JavaScript if it used with the
resolveNode method. For more information about the resolveNode
method, see the LiveCycle Designer Help or the Adobe XML Form Object Model
Reference.
Notation Description
Adobe LiveCycle Designer Referencing Objects in Calculations and Scripts
LiveCycle Designer Scripting Basics FormCalc reference syntax shortcuts 63
[ ] The square bracket ([ ]) notation denotes the occurrence value of an object. To
construct an occurrence value reference, place square brackets ([ ]) after an object
name, and enclose within the brackets one of the following values:
●[ n ], where n is an absolute occurrence index number beginning at 0. An
occurrence number that is out of range does not return a value. For example,
xfa.form.form1.#subform.Quantity[3]
refers to the fourth occurrence of the Quantity object.
●[ +/- n ], where n indicates an occurrence relative to the occurrence of the
object making the reference. Positive values yield higher occurrence numbers,
and negative values yield lower occurrence numbers. For example,
xfa.form.form1.#subform.Quantity[+2]
This reference yields the occurrence of Quantity whose occurrence number is
two more than the occurrence number of the container making the reference. For
example, if this reference was attached to the Quantity[2]object , the
reference would be the same as
xfa.template.Quantity[4]
If the computed index number is out of range, the reference returns an error.
The most common use of this syntax is for locating the previous or next
occurrence of a particular object. For example, every occurrence of the
Quantity object (except the first) might use Quantity[-1] to get the value of
the previous Quantity object.
●[*] indicates multiple occurrences of an object. The first named object is found,
and objects of the same name that are siblings to the first are returned. Note that
using this notation returns a collection of objects. For example,
xfa.form.form1.#subform.Quantity[*]
This expression refers to all objects with a name of Quantity that are siblings to
the first occurrence of Quantity found by the reference.
Note: In language-specific forms for Arabic, Hebrew, Thai, and Vietnamese, the
reference syntax is always on the right (even for right-to-left languages).
LiveCycle Forms 7.1 does not support form designs that contain Arabic,
Hebrew, Thai, and Vietnamese fonts.

Using the tree for reference, these expressions return the following objects:
●Subform_Page.Subform1[*] returns both Subform1 objects.
●Subform_Page.Subform1.Subform3.TextField2[*] returns the two
TextField2 objects. Subform_Page.Subform1 resolves to the first
Subform1 object on the left, and TextField2[*] evaluates relative to the
Subform3 object.
●Subform_Page.Subform1[*].TextField1 returns both of the
TextField1 instances. Subform_Page.Subform1[*] resolves to both
Subform1 objects, and TextField1 evaluates relative to the Subform1
objects.
●Subform_Page.Subform1[*].Subform3.TextField2[1] returns the
second and fourth TextField2 objects from the left.
Subform_Page.Subform1[*] resolves to both Subform1 objects, and
TextField2[1] evaluates relative to the Subform3 objects.
●Subform_Page.Subform1[*].Subform3[*] returns both instances of the
Subform3 object.
●Subform_Page.* returns both Subform1 objects and the Subform2 object.
●Subform_Page.Subform2.* returns the two instances of the
NumericField2 object.
Note: You can use the ‘[ ]’ (square bracket) syntax with JavaScript if it used with the
resolveNode method. For more information on the resolveNode method,

8Creating and Reusing JavaScript Functions
About the script object
The script object is an object you can use to store JavaScript functions and values separately from any
particular form object. Typically, you use the script object to create custom functions and methods that
you want to use as part of JavaScript scripts in many locations on your form. This technique reduces the
overall amount of scripting required to perform repetitive actions.
The script object only supports script written in JavaScript; however, there are no restrictions on the
location where the scripts are executed, provided that the scripting language for the event that invokes
the script object is set to JavaScript. Both Acrobat and LiveCycle Forms process scripting from a script
object in the same manner, but both are also distinct. Only scripts set to run on the client can make use of
script objects set to run on the client, and vice versa.
To create a script object
There are two parts to creating a script object. The first part involves adding the object to the form design,
and the second part is writing the script you want to store in the script object.
1. Create a new form or open an existing form.
2. In the Hierarchy palette, right-click either a form-level object or a subform-level object and select Insert
Script Object.
3. (Optional) Right-click the script object and select Rename Object.
To add script to a script object
After you have a script object on your form, you can add scripts using the Script Editor.
1. Select the script object in the Hierarchy palette.
Form level object
Form level
script object
Subform level object
Subform level
script object
Adobe LiveCycle Designer Creating and Reusing JavaScript Functions
LiveCycle Designer Scripting Basics To reference JavaScript functions stored in a script object 66
The Script Editor is displayed with both a Script Object value in the Show list and a JavaScript value in the
Language list. You cannot change either of these values.
2. Enter your script in the Script Source field.
3. When finished, click Enter Script Source Changes to add the script to your form.
Example
For example, create a script object called feedback that contains the following function:
function emptyCheck(oField) {
if ((oField.rawValue == null) || (oField.rawValue == "")) {
xfa.host.messageBox("You must input a value for this field.", "Error
Message", 3);
}
}
To reference JavaScript functions stored in a script object
After you add scripts to a script object, you can reference the script object from any event that supports
JavaScript scripts.
1. Select an object on your form and select an event from the Show list.
2. Create a reference to the script object and any functions within the script object. The following generic
syntax assumes that the object where you are referencing the script object is at the same level as the
script object in the form hierarchy or that the script object exists at the highest level of the form
hierarchy.
script_object.function_name(parameter1, ...);
3. Apply the new script to the form object and test it by previewing the form using the Preview PDF tab.
Similar to referencing other objects on a form, you must provide a valid syntax when referencing the script
object that includes where it exists within the form hierarchy. For more information about referencing
objects in scripting, see “Referencing object properties and values” on page 56.
Example
For example, using the script object example from “To add script to a script object” on page 65, place the
following JavaScript script on the exit event for a text field. Test the form using the Preview PDF tab.
feedback.emptyCheck(this);

9Debugging Calculations and Scripts
About debugging calculations and scripts
LiveCycle Designer includes a number of features and strategies for debugging your calculations and
scripts, depending on the scripting language you choose.
For both FormCalc and JavaScript, you can take advantage of certain LiveCycle Designer capabilities to
debug and verify your scripts.
●Using the Warnings tab in the Report palette, you can view any errors or messages generated by
LiveCycle Designer. This tab acts as a log of actions reported by LiveCycle Designer and updates when
you preview a form design by using the Preview PDF tab. For more information about using the
Warnings tab and the LiveCycle Designer workspace to debug your scripts, see “Using the workspace
to debug calculations and scripts” on page 14.
●Using the XML Form Object Model messageBox method to output information from an interactive
form into a dialog box at run time.
●For certain types of debugging, you may want to output information, such as field values or messages,
into a text field on your form design. For example, you can append new messages or values to the value
of a text field to create a log that you can refer to when resolving issues.
If you use Acrobat Professional, you can use the JavaScript Debugger from Acrobat to test your form
scripts. The JavaScript Debugger includes the JavaScript Console, which you can use to test portions of
JavaScript code in the Preview PDF tab. The JavaScript Console provides an interactive and convenient
interface for testing portions of JavaScript code and experimenting with object properties and methods.
Because of its interactive nature, the JavaScript Console behaves as an editor that supports the execution
of single lines or blocks of code.
For more information about the JavaScript Console and the JavaScript Debugger, see Developing Acrobat
Applications Using JavaScript at partners.adobe.com/public/developer/acrobat/devcenter.html (English
only).
Providing debugging feedback using the messageBox method
Regardless of the type of form you create, you can take advantage of the XML Form Object Model
messageBox method to display messages or field values at run time. When initiated, the messageBox
method displays a string value in a new client application dialog box. The string value can be a text
message that you create for debugging purposes or the string value of fields or expressions.
For example, consider a scenario with a simple form design that contains a single numeric field
(NumericField1) and a button (Button1). In this case, the following FormCalc calculation and JavaScript
script each output a message displaying some text and the value currently displayed in the numeric field.
By adding either the calculation or the script to the click event of the button object, you can
interactively display the value of the numeric field in a new dialog box by clicking the button.
FormCalc
xfa.host.messageBox(Concat("The value of NumericField1 is: ",
NumericField1), "Debugging", 3)
Adobe LiveCycle Designer Debugging Calculations and Scripts
LiveCycle Designer Scripting Basics To enable the JavaScript Debugger for LiveCycle Designer 68
JavaScript
xfa.host.messageBox("The value of NumericField1 is: " +
NumericField1.rawValue, "Debugging", 3);
Caution: The messageBox method returns an integer value representing the button that the form filler
selects in the message box dialog. If you attach the messageBox method to the calculate
event of a field object, and the messagebox method is the last line of the script, the field
displays the return value of the messageBox method at run time.
In some situations, such as if you want to return a message box during a calculate event, you can take
advantage of the alert method from the JavaScript Object Model from Acrobat. For example, the
following script returns the value of a text field:
var oField = xfa.resolveNode("TextField1").rawValue;
app.alert(oField);
For more information about the alert method and the JavaScript Object Model from Acrobat, see
Developing Acrobat Applications Using JavaScript at
partners.adobe.com/public/developer/acrobat/devcenter.html (English only).
To enable the JavaScript Debugger for LiveCycle Designer
To enable the JavaScript Debugger for LiveCycle Designer and execute code from the JavaScript Console,
you must enable JavaScript and the JavaScript Debugger in Acrobat Professional. You need to enable the
JavaScript Debugger to access the JavaScript Console because the console window is a component in the
JavaScript Debugger interface.
Note: You can enable the JavaScript Debugger in Adobe Reader if you have LiveCycle Reader Extensions
installed. To enable the JavaScript Debugger in Adobe Reader, you need to get the debugger.js file
and then edit the Microsoft Windows Registry. For more information about enabling the JavaScript
Debugger in Adobe Reader, see Developing Acrobat Applications Using JavaScript at
partners.adobe.com/public/developer/acrobat/devcenter.html (English only).

11. In LiveCycle Designer, click the Preview PDF tab.
12. Press Ctrl+J to open the JavaScript Debugger.
To prevent the JavaScript Debugger from disappearing in
LiveCycle Designer
If you have the JavaScript Debugger from Acrobat active and it disappears when you click components in
the LiveCycle Designer interface, you must stop the Acrobat.exe process in the Microsoft Windows Task
Manager. The Acrobat.exe process continues to run after Acrobat is closed so that Acrobat is displayed
faster if it is restarted. Stopping the Acrobat.exe process ends the association between the JavaScript
Debugger and the Acrobat Professional session so that you can use the JavaScript Debugger in
LiveCycle Designer.
1. In the Windows Task Manager, click the Processes tab.
2. In the Image Name column, right-click Acrobat.exe and select End Process.
Executing scripts in the JavaScript Console
Using the JavaScript Console from Acrobat, you can to evaluate single or multiple lines of code.
There are three ways to evaluate JavaScript code while using the interactive JavaScript Console:
●To evaluate a portion of a line of code, highlight the portion in the console window and press either
Enter on the numeric keypad or Ctrl+Enter on the regular keyboard.
●To evaluate a single line of code, make sure the cursor is positioned in the appropriate line in the
console window and press either Enter on the numeric keypad or Ctrl+Enter on the regular keyboard.
●To evaluate multiple lines of code, highlight those lines in the console window and press either Enter
on the numeric keypad or Ctrl+Enter on the regular keyboard.
In all cases, the result of the most recently evaluated JavaScript script is displayed in the console window.
After evaluating each JavaScript script, the console window prints out undefined, which is the return
value of the statement. Notice that the result of a statement is not the same as the value of an expression
within the statement. The return value undefined does not mean that the value of script is undefined; it
means that the return value of the JavaScript statement is undefined.
Click Clear (the trash can icon) at the lower right of the console to delete any contents that appear in the
console window.
Adobe LiveCycle Designer Debugging Calculations and Scripts
LiveCycle Designer Scripting Basics Providing debugging feedback using the JavaScript Console 70
Providing debugging feedback using the JavaScript Console
If you are creating scripts using JavaScript, you can output messages to the JavaScript Console from
Acrobat at run time by using the console.println method included with the JavaScript Object Model
from Acrobat. When initiated, the console.println method displays a string value in the JavaScript
Console. The string value can be a text message that you create for debugging purposes or the string
value of fields or expressions.
For example, consider a scenario with a simple form design that contains a single numeric field
(NumericField1) and a button (Button1). In this case, the following JavaScript script outputs a message
displaying some text and the value currently displayed in the numeric field. By adding either the
calculation or the script to the click event of the button object, you can interactively display the value of
the numeric field in a new dialog box by clicking the button.
console.println("The value is: " + NumericField1.rawValue);
For more information about the console.println method and the JavaScript Object Model from
Acrobat, see Developing Acrobat Applications Using JavaScript at

10 Working with a Host Application
About working with a host application
A host application is the application in which a form exists at any given time. For example, if you are using
LiveCycle Forms to render a form in HTML format, then during the pre-rendering process the host
application is LiveCycle Forms. Once you render a form and view it in a client application such as Acrobat,
Adobe Reader, or an HTML browser, then the client application becomes the host application.
LiveCycle Designer includes a scripting model that provides scripting properties and methods for directly
interfacing with a hosting application. For example, you can use the properties and methods in the host
scripting model to provide PDF page navigation actions in Acrobat or Adobe Reader, or you can use the
importData method to load data into your form.
You can reference the host script model syntax on any valid scripting event for form design objects using

11 Working with the Event Model
About the event model
The event model stores object event properties. These properties are useful if you want to access values
that are otherwise out of the scope of the events listed in the Show list within the Script Editor.
The event model controls the changes in a form that occur before, during, and after actions take place.
These actions include dynamic form events, such as the point when the data and form design are merged
but before pagination is applied, and also interactive form events, such as when a user updates the value
of a field.
Event model properties and methods
Using the event object properties and methods, you can retrieve information and execute actions that
otherwise are not accessible through calculations and scripts. For example, you can retrieve the full value
of a field that otherwise would have part of the data stripped out because it is too long or otherwise
invalid. Retrieving the full value of a field is useful in situations where you have to do extensive error
checking.

12 Moving from Scripting in Acrobat to
LiveCycle Designer
About moving from scripting in Acrobat to LiveCycle Designer
LiveCycle Designer includes extensive scripting capabilities, including support for the most common
JavaScript objects from Acrobat. When you convert an Acrobat form to LiveCycle Designer, most
JavaScript scripts continue to work without requiring changes. However, you will need to manually
convert some JavaScript scripts from Acrobat to maintain the behavior of your Acrobat form.
When converting scripts on your Acrobat form, note that LiveCycle Designer scripting differs from
scripting in Acrobat in several ways:
●LiveCycle Designer workspace In the LiveCycle Designer workspace, you can change object
properties and behaviors on your form without requiring you to create scripts.
●Scripting languages LiveCycle Designer includes support for JavaScript as well as for FormCalc,
which is a simple calculation language. FormCalc includes built-in functions that perform many useful
operations that would otherwise require extensive scripting.
●Referencing objects, properties, and methods LiveCycle Designer forms are highly structured;
therefore, to reference specific objects, properties, or methods, you must include the appropriate
reference syntax in your script. You can use the statement completion options in the Script Editor to assist
you in creating reference syntaxes.
It is possible to continue to use JavaScript objects, properties, and methods from Acrobat in
LiveCycle Designer. However, you should consider JavaScript from Acrobat only for tasks that you cannot
perform using the XML Form Object Model in LiveCycle Designer. For example, you can use JavaScript
from Acrobat to add attachments, bookmarks, and annotations; search or spell check the form; create
reports; or access and manipulate metadata. You cannot use JavaScript from Acrobat to perform actions
such as setting field values, adding new fields to a form, or deleting pages from a form.
Note: You cannot use Acrobat to add JavaScript scripts to a LiveCycle Designer form, including Acrobat
forms that you have converted using LiveCycle Designer. When you view a LiveCycle Designer form
in Acrobat, all JavaScript tools are unavailable.
For more information about converting Acrobat scripting to LiveCycle Designer, see the article Converting
Acrobat JavaScript for Use in LiveCycle Designer Forms in the LiveCycle Developer Center at
www.adobe.com/devnet/livecycle/.
Adobe LiveCycle Designer Moving from Scripting in Acrobat to LiveCycle Designer
LiveCycle Designer Scripting Basics Converting Acrobat forms that contain scripts 77
Converting Acrobat forms that contain scripts
One of the first steps in converting a form from Acrobat to LiveCycle Designer is to determine how much of
the Acrobat scripting is supported by LiveCycle Designer and how much you must convert.
In general, you should convert all Acrobat scripting to an equivalent in LiveCycle Designer.
LiveCycle Designer scripting takes full advantage of the highly structured nature of LiveCycle Designer
forms, as well as useful forms-specific functionality, to make designing and implementing your forms
solution faster and easier.
The Acrobat scripting you should retain include those that deal with the form’s environment and
peripheral operations, such as adding attachments or multimedia, performing searches, or creating
reports and handling document metadata.
For more information about converting Acrobat scripting to LiveCycle Designer, see the article Converting
Acrobat JavaScript for Use in LiveCycle Designer Forms in the LiveCycle Designer Developer Center at
www.adobe.com/devnet/livecycle/.
Using JavaScript objects from Acrobat in LiveCycle Designer
In LiveCycle Designer, you can script against certain JavaScript objects in Acrobat by using the Acrobat
scripting syntax. As a result, you can use the properties and methods of those objects on your form. For
example, to display a message in the JavaScript Console from Acrobat, you can add the following script to
the event of a form design object in LiveCycle Designer:
console.println("This message appears in the JavaScript Console.");
You can also have the form send itself by email by adding the following script to the click event of a
button:
var myDoc = event.target;
myDoc.mailDoc(true);
Note: In LiveCycle Designer, you must ensure that the scripting language for the event is set to JavaScript
so that the script will execute correctly at run time.
You can also use references to the JavaScript objects in Acrobat in your reference syntax. For example, the
following script gets the signed state of a document signature field and takes an action based on the state:
// Proceed if the current field is not signed.
var oState =
event.target.getField("form1[0].#subform[0].SignatureField1[0]")
.signatureValidate(); //Get the field's signed state.
if (oState == 0) {
...
}
Note: This example uses a fully qualified reference syntax to reference the text For more information
about referencing form design objects, see “Referencing object properties and values” on page 56.
When working with JavaScript from Acrobat in LiveCycle Designer, remember these points:
●In LiveCycle Designer, use event.target to access the Doc JavaScript object from Acrobat. In
Acrobat, the this object is used to reference the Doc object; however, in LiveCycle Designer, the this
object refers to the form design object to which the script is attached.
Adobe LiveCycle Designer Moving from Scripting in Acrobat to LiveCycle Designer
LiveCycle Designer Scripting Basics JavaScript objects from Acrobat supported in LiveCycle Designer 78
●The Script Editor has no statement completion for JavaScript objects from Acrobat. You should refer to
the JavaScript for Acrobat API Reference in the Acrobat Family Developer Center at
partners.adobe.com/public/developer/acrobat/devcenter.html.
For more information about converting Acrobat scripting to LiveCycle Designer, see the article Converting
Acrobat JavaScript for Use in LiveCycle Designer Forms in the LiveCycle Developer Center at
www.adobe.com/devnet/livecycle/.
JavaScript objects from Acrobat supported in LiveCycle Designer
The following table lists the availability of the most commonly used Acrobat objects, properties, and
methods in LiveCycle Designer, and provides information on any equivalent functionality in
LiveCycle Designer. Although the table contains the most commonly used Acrobat objects, properties and
methods, some are not listed, such as multimedia objects, because they are rarely used for forms.
In cases where no equivalent LiveCycle Designer functionality is listed, no direct LiveCycle Designer
property or method can reproduce the Acrobat behavior. However, you can still create custom functions or
scripts to replicate the Acrobat capability.

13 Examples of Common Scripting Tasks
This chapter will contain examples of using JavaScript scripts to perform specific tasks or outcomes.
Initially, several samples will be included based on content that is posted to the LiveCycle Designer
Developer Center, with the potential for more samples to be added in subsequent releases of this guide.
The samples that we plan to include for the first version of this guide are:
●Changing the background colors of fields, fillable areas, and subforms
●Hiding and showing objects
●Changing the visual properties of an object on the client
●Getting the current or previous value of a drop-down list
●Adjusting the height of a field at run time
●Setting a field as required at run time
●Calculating the field sums
●Highlighting fields in response to form filler interaction
●Resetting the values of the current subform
●Changing the presence of a form design object
●Using the properties of the instance manager to control subforms
●Using the methods of the instance manager to control subforms
●Using the instance manager to control subforms at run time
About the scripting examples
The scripting examples demonstrate quick and simple techniques that you can apply to your own work.
For more examples and ideas, visit the LiveCycle Developer Center at www.adobe.com/devnet/livecycle.
Changing the background colors of fields, fillable areas, and
subforms
This example demonstrates how to change the background color of subforms, fields, and fillable areas on
a form in response to form filler interaction at run time.
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Changing the background colors of fields, fillable areas, and subforms 92
In this example, clicking a button changes the background color of an associated object.
Note: To manipulate the background color of objects at run time, you must save your form as an Acrobat
Dynamic XML Form file.
To see this scripting example and others, visit the LiveCycle Developer Center at
www.adobe.com/devnet/livecycle.
➤Scripting the subform and text field background colors
You set the subform and the text field background colors by using the fillColor method. For example,
the following line is the script for the subform:
Subform1.fillColor = "17,136,255";
The following lines make up the script for the background color of the text fields:
Subform1.Name.fillColor = "102,179,255";
Subform1.Address.fillColor = "102,179,255";
Subform1.City.fillColor = "102,179,255";
Subform1.State.fillColor = "102,179,255";
Subform1.ZipCode.fillColor = "102,179,255";
Subform1.Country.fillColor = "102,179,255";
➤Scripting the fillable area background color
When setting the background color or the fillable area for each text field, your scripts must access
properties that require a reference syntax expression that includes the number sign (#). Because JavaScript
does not interpret the number sign (#) properly in reference syntax expressions, the script uses the
resolveNode method to resolve the expression.
xfa.resolveNode("Subform1.Name.ui.#textEdit.border.fill.color").value =
"153,204,255";
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Hiding and showing objects 93
xfa.resolveNode("Subform1.Address.ui.#textEdit.border.fill.color").value =
"153,204,255";
xfa.resolveNode("Subform1.City.ui.#textEdit.border.fill.color").value =
"153,204,255";
xfa.resolveNode("Subform1.State.ui.#textEdit.border.fill.color").value =
"153,204,255";
xfa.resolveNode("Subform1.ZipCode.ui.#textEdit.border.fill.color").value =
"153,204,255";
xfa.resolveNode("Subform1.Country.ui.#textEdit.border.fill.color").value =
"153,204,255";
➤Scripting the Clear All button
The script for the Clear All button uses the remerge method to remerge the form design and form data. In
this case, the method effectively restores the fields, fillable areas, and subforms to their original state.
xfa.form.remerge();
Hiding and showing objects
This example demonstrates how to hide buttons when printing a form, as well as how to hide and show
objects by changing the presence values at run time.
In this example, all form objects are showing in the form.
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Hiding and showing objects 94
The form filler can use the drop-down lists in the Presence Values area to show or hide objects. In the
following diagram, the Address field is hidden and the form layout has adjusted accordingly. The Print
Form button is also invisible.
Note: To hide and show objects at run time, you must save your form as an Acrobat Dynamic PDF Form
file.
To see this scripting example and others, visit the LiveCycle Developer Center
www.adobe.com/devnet/livecycle.
➤Scripting the presence values for subforms
The script for the subform presence values uses a switch statement to handle the three presence options
that a form filler can apply to the subform object:

LiveCycle Designer Scripting Basics Hiding and showing objects 95
➤Scripting the presence values for text fields
The script for the text fields presence values requires two variables. The first variable stores the number of
objects contained in Subform1:
var nSubLength = Subform1.nodes.length;
The second variable stores the name of the text field that the form filler selects in the Text Fields
drop-down list:
var sSelectField = fieldList.rawValue;
The following script uses the replace method to remove all of the spaces from the name of the field
stored in the sSelectField variable, which allows the value of the drop-down list to match the name of
the object in the Hierarchy palette:
sSelectField = sSelectField.replace(' ', '');
This script uses a For loop to cycle through all of the objects contained in Subform1:
for (var nCount = 0; nCount < nSubLength; nCount++) {
If the current object in Subform1 is of type field and the current object has the same name as the object
that the form filler selected, the following switch cases are performed:
if ((Subform1.nodes.item(nCount).className == "field") &
(Subform1.nodes.item(nCount).name == sSelectField)) {
The following script uses a switch statement to handle the three presence values that a form filler can
apply to text field objects:
switch(xfa.event.newText) {
case 'Invisible':
Subform1.nodes.item(nCount).presence = "invisible";
break;
case 'Hidden (Exclude from Layout)':
Subform1.nodes.item(nCount).presence = "hidden";
break;
default:
Subform1.nodes.item(nCount).presence = "visible";
break;
}
}
}
➤Scripting the presence values for buttons
The script for the buttons presence values requires two variables. This variable stores the number of
objects contained in Subform1:
var nSubLength = Subform1.nodes.length;
This variable stores the name of the button that the form filler selects in the Buttons drop-down list:
var sSelectButton = buttonList.rawValue;
The following script uses the replace method to remove all of the spaces from the name of the button
stored in the sSelectField variable, which allows the value of the drop-down list to match the name of
the object in the Hierarchy palette:
sSelectButton = sSelecButton.replace(/\s/g, '');
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Hiding and showing objects 96
This script uses a For loop to cycle through all of the objects contained in Subform1:
for (var nCount = 0; nCount < nSubLength; nCount++) {
If the current object in Subform1 is of type field and the current object has the same name as the object
that the form filler selected, perform the following switch cases:
if ((Subform1.nodes.item(nCount).className == "field") &
Subform1.nodes.item(nCount).name == sSelectButton)) {
This script uses a switch statement to handle the five presence values that a form filler can apply to
button objects.
Note: The relevant property indicates whether an object should appear when the form is printed.
switch(xfa.event.newText) {
case 'Invisible':
Subform1.nodes.item(nCount).presence = "invisible";
break;
case 'Hidden (Exclude from Layout)':
Subform1.nodes.item(nCount).presence = "hidden";
break;
case 'Visible (but Don\'t Print)':
Subform1.nodes.item(nCount).presence = "visible";
Subform1.nodes.item(nCount).relevant = "-print";
break;
case 'Invisible (but Print Anyway)':
Subform1.nodes.item(nCount).presence = "invisible";
Subform1.nodes.item(nCount).relevant = "+print";
break;
default:
Subform1.nodes.item(nCount).presence = "visible";
break;
}
}
}
➤Scripting for resetting the drop-down lists
Use the resetData method to reset all of the drop-down lists to their default values:
xfa.host.resetData();
Use the remerge method to remerge the form design and form data. In this case, the method effectively
returns the objects in the Form Objects area to their original states:
xfa.form.remerge();
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Changing the visual properties of an object on the client 97
Changing the visual properties of an object on the client
The example demonstrates how to manipulate the visual properties of an object; in this case, a text field.
For example, selecting the Make the Field Wider check box expands the fillable area of the text field to four
inches.
Note: To alter the visual properties of objects on the client, you must save your form as an Acrobat
Dynamic PDF Form file.
In this example, the check boxes do not have unique object names; therefore, LiveCycle Designer assigns
an instance value to reference the object. The check box script uses an if-else statement to give the
effect of selecting and deselecting.
To see this scripting example and others, visit the LiveCycle Developer Center
www.adobe.com/devnet/livecycle.
➤Scripting for the Move the Field check box
When the check box is selected, the field is moved according to the x and y settings. When the check box is
deselected, the field is returned to its original location.

Getting the current or previous value of a drop-down list
This example demonstrates how to obtain the current value of a drop-down list as well as the different
ways to access the previous value of a drop-down list on a form. In addition to the actual scripts that set
the current and previous values, it is important to note that the scripts are located on the change event
for the drop-down list.
In the following example, when a form filler selects a value from the drop-down list, the selected value
appears in the Current Value field. Then, when the form filler selects another value from the drop-down
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Getting the current or previous value of a drop-down list 101
list, the new value appears in the Current Value List and the previous value appears in the Previous Value 1
field.
Note: Each of the methods for obtaining the previous value of a drop-down list uses a different script. The
Previous Value 1 text field is populated by a direct reference to the rawValue property of the
drop-down list, whereas the Previous Value 2 text field is populated using the prevText property.
For consistent results, it is recommended that you access the previous value by using the
prevText property.
To see this scripting example and others, visit the LiveCycle Developer Center at
www.adobe.com/devnet/livecycle.
➤Scripting for populating the Current Value text field
Populate the value of the Current Value text field by using the newText property:
CurrentValue.rawValue = xfa.event.newText;
➤Scripting for populating the Previous Value 1 text field
Populate the value of the Previous Value 1 text field by referencing the rawValue of the drop-down list:
PreviousValue1.rawValue = DropDownList.rawValue;
➤Scripting for populating the Previous Value 2 text field
Populate the value of the Previous Value 2 text field by using the prevText property:
PreviousValue2.rawValue = xfa.event.prevText;

LiveCycle Designer Scripting Basics Adjusting the height of a field at run time 102
Adjusting the height of a field at run time
The example demonstrates how to expand a field to match the height of the content in another field.
In this example, when the form filler types multiple lines in TextField1 and then clicks the Expand button,
the height of TextField2 increases to match the height of TextField1.
To see this scripting example and others, visit the LiveCycle Developer Center at
www.adobe.com/devnet/livecycle.
➤Scripting for the Expand button
The following script is for the Expand button:
var newHeight = xfa.layout.h(TextField1, "in");
TextField2.h = newHeight + "in";
Setting a field as required at run time
This example demonstrates how to make a field required at run time.
In this example, when the Set as Required button is clicked, if the form filler attempts to submit a form
without typing some text in TextField1, an error message appears.
To see this scripting example and others, visit the LiveCycle Developer Center
www.adobe.com/devnet/livecycle.
➤Scripting for the Set as Required button
The following script is for the Set as Required button:
TextField1.validate.nullTest = "error";
You can also use one of these two scripts:
TextField1.mandatory = "error"
TextField1.mandatoryMessage = "this field is mandatory!"

LiveCycle Designer Scripting Basics Calculating the field sums 103
Calculating the field sums
This example demonstrates how to calculate the sums of fields located at different levels of the form
hierarchy when the form filler opens the form in a client application, such as Acrobat Professional,
Adobe Reader, or HTML client.
To see this scripting example and others, visit the LiveCycle Developer Center at
www.adobe.com/devnet/livecycle.
➤Scripting for calculating the sum of repeating fields in a form
To calculate the sum of repeating fields in a form, you add a calculate event to the Sum field:
var fields = xfa.resolveNodes("NumericField1[*]");
var total = 0;
for (var i=0; i <= fields.length-1; i++) {
total = total + fields.item(i).rawValue;
}
this.rawValue = total;
➤Scripting for calculating the sum of repeating fields
Similarly, to calculate the sum of repeating fields, you add a calculate event to the Sum field:
var fields = xfa.resolveNodes("detail[*].NumericField1");
var total = 0;
for (var i=0; i <= fields.length-1; i++) {
total = total + fields.item(i).rawValue;
}
this.rawValue = total;
➤Scripting to calculate the sum of the fields on the page
To calculate the sum of the fields on the page, you add a calculate event to the Sum field:
var fields = xfa.layout.pageContent(0 , "field", 0);
var total = 0;
for (var i=0; i <= fields.length-1; i++) {
if (fields.item(i).name == "NumericField1") {
total = total + fields.item(i).rawValue;
}

}
this.rawValue = total;
Highlighting fields in response to form filler interaction
This example demonstrates how to highlight the current field that a form filler is working with, highlight
fields that a form filler is required to fill, and use message boxes to provide feedback to the form filler.
In this example, an asterisk (*) appears to the right of the required fields. When a field is selected, the field
border changes to blue. If the form filler clicks the Verify Data button without having filled the required
fields, a message appears and the field changes to red. If all the required fields are filled, a confirmation
message appears when the form filler clicks the Verify Data button.
To see this scripting example and others, visit the LiveCycle Developer Center at
www.adobe.com/devnet/livecycle.
➤Scripting for adding a blue border around a selected field
To add the blue border around the selected field, add the following scripts to each text field:
For example, add an enter event to the Name field:
Name.border.edge.color.value = "0,0,255";
For example, add an exit event to the Name field:
Name.border.edge.color.value = "255,255,255";
For example, add a mouseEnter event to the Name field:
Name.border.edge.color.value = "0,0,255";
For example, add a mouseExit event to the Name field:

Name.border.edge.color.value = "255,255,255";
➤Scripting for the Verify Data button
The following script, which is created for the Verify Data button, performs a series of checks to verify that
the required fields contain data. In this case, each field is individually checked to verify that the value of the
field is non-null or an empty string. If the value of the field is null or an empty string, an alert message
appears indicating that data must be input into the field and the background color of the fillable area is
changed to red.
Use this variable to indicate whether a field does not contain data:
var iVar = 0;
if ((Name.rawValue == null) || (Name.rawValue == "")) {
xfa.host.messageBox("Please enter a value in the Name field.");
This script changes the color of the fillable area of the text field:
xfa.resolveNode("Name.ui.#textEdit.border.edge").stroke = "solid";
xfa.resolveNode("Name.ui.#textEdit.border.fill.color").value =
"255,100,50";
// Set the variable to indicate that this field does not contain data.

Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Changing the presence of a form design object 108
To reset the default values add a click event to the Clear button. You need a dynamic reference syntax
expression because the detail is a repeating subform and must be reflected in the reference syntax
expression. In this situation, it is easier to build the resetData parameters separately.
var f1 = this.parent.somExpression + ".TextField2" + ",";
var f2 = f1 + this.parent.somExpression + ".DropDownList1" + ",";
var f3 = f2 + this.parent.somExpression + ".NumericField1";
// ...and pass the variable as a parameter.
xfa.host.resetData(f3);
Changing the presence of a form design object
LiveCycle Designer provides the following presence settings for the different objects on a form through
various tabs in the Object palette. The Invisible and Hidden (Exclude from Layout) settings are unavailable
for groups, content areas, master pages, page set, and subform set objects.
Note: To change the presence setting of an object by using scripts, you must change the value of two
underlying XML Form Object Model properties: presence and relevant.
The following table lists the presence settings and the corresponding reference syntax.

LiveCycle Designer Scripting Basics Using the properties of the instance manager to control subforms 109
Using the properties of the instance manager to control subforms
This example demonstrates how to use the properties of the instance manager (which is part of the XML
Form Object Model) to retrieve information about subforms at run time.
In the following form, the four buttons provide information about Subform1 by using the instance
manger’s scripting properties. For example, when the form filler clicks the Max button, a message
describing the allowed maximum number of supported Subform1 instances appears.
➤Scripting for the message box to output the value of the count property
The following script uses the messageBox method to output the value of the count property:
xfa.host.messageBox("The current number of Subform1 instances on the
form is:" + properties.Subform1.instanceManager.count, "Instance Manager
Properties",3);
You can also write this script by using the underscore (_) notation to reference the count property of the
instance manager, as shown here:
xfa.host.messageBox("The current number of Subform1 instances on the form
is: " + properties._Subform1.count, "Instance Manager Properties", 3);

The underscore (_) notation is especially important if no subform instances currently exist on the form.
➤Scripting for the message box to output the value of the max property
The following script uses the messageBox method to output the value of the max property:
xfa.host.messageBox("The maximum number of instances allowed for Subform1
is: " + properties.Subform1.instanceManager.max, "Instance Manager
Properties", 3);
You can also write this script by using the underscore (_) notation to reference the max property of the
instance manager, as shown here:
xfa.host.messageBox("The maximum number of instances allowed for Subform1
is: " + properties._Subform1.max, "Instance Manager Properties", 3);
➤Scripting for the message box to output the value of the min property
The following script uses the messageBox method to output the value of the min property:
xfa.host.messageBox("The minimum number of instances allowed for Subform1
is: " + properties.Subform1.instanceManager.min, "Instance Manager
Properties", 3);
You can also write this script by using the underscore (_) notation to reference the min property of the
instance manager, as shown here:
xfa.host.messageBox("The minimum number of instances allowed for Subform1
is: " + properties._Subform1.min, "Instance Manager Properties", 3);
➤Scripting for the message box to output the name of the subform property
The following script uses the messageBox method to output the name of the subform property:
xfa.host.messageBox("The name of the subform using the instance manager name
property is: " + properties.Subform1.instanceManager.name +
".\n\nNote: This value is different than the value returned by the name
property for the Subform1 object." , "Instance Manager Properties", 3);
You can also write this script by using the underscore (_) notation to reference the name property of the
instance manager, as shown here:
xfa.host.messageBox("The name of the subform using the instance manager name
property is: " + properties._Subform1.name +
".\n\nNote: This value is different than the value returned by the name
property for the Subform1 object." , "Instance Manager Properties", 3);
Using the methods of the instance manager to control subforms
This example demonstrates how to use the methods of the instance manager (which is part of the XML
Form Object Model) to perform operations on subform objects at run time. For example, you can add
remove instances of a particular subform, table, or table row.
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Using the methods of the instance manager to control subforms 111
In the following form, the form filler uses the four buttons to use the various instance manager scripting
methods. For example, when the form filler clicks the Add button a new Subform2 instance is added to the
form.
Note: The Move button reorders the first two Subform2 instances, and the Set button displays the
maximum number of Subform2 instances. In both cases, you may need to add or remove subforms,
or make changes to the data in the text fields to see the changes applied to the Subform2 instances.
➤Scripting to determine whether you added the maximum number of subforms to a form
The following script determines whether the supported maximum number of Subform2 instances exist on
the form. If the maximum number exists, the script displays a message. Otherwise, a new Subform2
instance is added to the form.
if (methods.Subform2.instanceManager.count ==
methods.Subform2.instanceManager.max) {
xfa.host.messageBox("You have reached the maximum number of items allowed.",
"Instance Manager Methods", 1);
}
else {
methods.Subform2.instanceManager.addInstance(1);
xfa.form.recalculate(1);
}
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
if (methods._Subform2.count == methods._Subform1.max) {
xfa.host.messageBox("You have reached the maximum number of items
allowed.", "Instance Manager Methods", 1);
}
else {
methods._Subform2.addInstance(1);
xfa.form.recalculate(1);
}
➤Scripting to determine whether there are more subforms to remove on the form
The following script determines whether any Subform2 instances exist on the form. If none exist, the script
displays a message indicating that no instances exist. If instances do exist, the script removes the first
instance from the form.
if (methods.Subform2.instanceManager.count == 0) {
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Using the instance manager to control subforms at run time 112
xfa.host.messageBox("There are no subform instances to remove.",
"Instance Manager Methods", 1);
}
else {
methods.Subform2.instanceManager.removeInstance(0);
xfa.form.recalculate(1);
}
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
if (methods._Subform2.count == 0) {
xfa.host.messageBox("There are no subform instances to remove.",
"Instance Manager Methods", 1);
}
else {
methods._Subform2.removeInstance(0);
xfa.form.recalculate(1);
}
➤Scripting to force four subform instances to appear on the form
The following script forces four Subform2 instances to appear on the form regardless of how many
instances currently exist:
methods.Subform2.instanceManager.setInstances(4);
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
methods._Subform2.setInstances(4);
➤Scripting to force the first and second subforms to switch locations on the form
The following script forces the first and second Subform2 instances to switch locations on the form.
methods.Subform2.instanceManager.moveInstance(0,1);
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here.
methods._Subform2.moveInstance(0,1);
Using the instance manager to control subforms at run time
This example demonstrates how to use properties and methods of the instance manager to retrieve
information about subforms and perform operations on subform objects at run time.
In this example, the form filler uses the buttons to perform various actions using instances of Subform3.
For example, when the form filler clicks the Add Row Below button a new Subform3 instance is added
below the current instance.

LiveCycle Designer Scripting Basics Using the instance manager to control subforms at run time 113
Note: You may need to add or remove subforms, or make changes to the data in the text field, to see the
changes applied to the instances of Subform3.
Tip: If no instances of a particular subform exist on your form, you must use the underscore (_) notation
provided with each example below. For more information about using the underscore (_) notation,
see the LiveCycle Designer Help.
➤Scripting the Add a New Subform button
The following script determines whether the supported maximum number of Subform3 instances exist on
the form. If the maximum number exist, the script displays a message. Otherwise, a new Subform3
instance is added to the form.
if (advanced.Subform3.instanceManager.count ==
advanced.Subform3.instanceManager.max) {
xfa.host.messageBox("You have reached the maximum number of items
allowed.","Combining Instance Manager Concepts", 1);
}
else {
advanced.Subform3.instanceManager.addInstance(1);
xfa.form.recalculate(1);
}
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
if (advanced._Subform3.count == advanced._Subform3.max) {
xfa.host.messageBox("You have reached the maximum number of items
allowed.", "Combining Instance Manager Concepts", 1);
}
else {
advanced._Subform3.addInstance(1);
xfa.form.recalculate(1);
}

➤Scripting the Remove a Subform button
The following script determines whether any Subform3 instances exist on the form. If none exist, the script
displays a message indicating that no instances exist. If instances exist, the script removes the first instance
from the form.
if (advanced.Subform3.instanceManager.count == 0) {
xfa.host.messageBox("There are no subform instances to remove.",
"Combining Instance Manager Concepts", 1);
}
else {
advanced.Subform3.instanceManager.removeInstance(0);
}
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
if (advanced._Subform3.count == 0) {
xfa.host.messageBox("There are no subform instances to remove.",
"Combining Instance Manager Concepts", 1);
}
else {
advanced._Subform3.removeInstance(0);
}
➤Scripting the Add Instance Below button
The following if-else statement prevents the script from proceeding if the form currently contains the
maximum number of Subform3 instances:
if (Subform3.instanceManager.count < Subform3.instanceManager.occur.max) {
//oNewInstance stores an instance of Subform3 created by the addInstance()
method.
var oNewInstance = Subform3.instanceManager.addInstance(1);
//nIndexFrom and nIndexTo store the before and after index values to use with
the moveInstance() method.
var nIndexFrom = oNewInstance.index;
var nIndexTo = Subform3.index + 1;
In this case, when the script references the value for nIndexFrom, the new instance of Subform3 is added
to the form in the position specified in the moveInstance method:
Subform3.instanceManager.moveInstance(nIndexFrom, nIndexTo);
}
else {
xfa.host.messageBox("You have reached the maximum number of items
allowed.", "Combining Instance Manager Concepts", 1);
}
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
if (_Subform3.count < _Subform3.occur.max) {
var oNewInstance = _Subform3.addInstance(1);
var nIndexFrom = oNewInstance.index;
var nIndexTo = Subform3.index + 1;
_Subform3.moveInstance(nIndexFrom, nIndexTo);
}

else {
xfa.host.messageBox("You have reached the maximum number of items allowed.",
"Combining Instance Manager Concepts", 1);
}
➤Scripting the Delete This Instance button
The following if-else statement prevents the script from proceeding if the form currently contains the
minimum number of Subform3 instances.
if (Subform3.instanceManager.count > Subform3.instanceManager.occur.min) {
This script uses the removeInstance method to remove an instance of Subform3.
Note: This script uses the value parent.parent.index to indicate the Subform3 instance to remove.
The parent reference indicates the container of the object using the reference. In this case, using
the reference parent.index would indicate the untitled subform that contains the Add Instance
Below, Delete This Instance, Move Row Up, and Move Row Down buttons.
Subform3.instanceManager.removeInstance(parent.parent.index);
}
else {
xfa.host.messageBox("You have reached the minimum number of items
allowed.", "Combining Instance Manager Concepts", 1);
}
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
if (_Subform3.count > _Subform3.occur.min) {
Subform3.removeInstance(Subform3.index);
}
else {
xfa.host.messageBox("You have reached the minimum number of items allowed.",
"Combining Instance Manager Concepts", 1);
}
➤Scripting the Move Row Up button
The following if-else statement prevents the script from proceeding if the instance of Subform3 appears as
the first instance in the list:
if (Subform3.index != 0) {
//nIndexFrom and nIndexTo store the before and after index values to use with
the moveInstance method.
var nIndexFrom = Subform3.index;
var nIndexTo = Subform3.index - 1;
Subform3.instanceManager.moveInstance(nIndexFrom, nIndexTo);
}
else {
xfa.host.messageBox("The current item cannot be moved because it is the
first instance in the list.", "Combining Instance Manager Concepts", 1);
}
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
if (Subform3.index != 0) {
Adobe LiveCycle Designer Examples of Common Scripting Tasks
LiveCycle Designer Scripting Basics Using the instance manager to control subforms at run time 116
var nIndexFrom = Subform3.index;
var nIndexTo = Subform3.index - 1;
Subform3.moveInstance(nIndexFrom, nIndexTo);
}
else {
xfa.host.messageBox("The current item can't be moved since it already is the
first instance in the list.", "Combining Instance Manager Concepts", 1);
}
➤Scripting the Move Row Down button
This variable stores the index value of the instance of Subform3:
var nIndex = Subform3.index;
The following if-else statement prevents the script from proceeding if the instance of Subform3 appears as
the last instance in the list:
if ((nIndex + 1) < Subform3.instanceManager.count) {
// nIndexFrom and nIndexTo store the before and after index values to use with
the moveInstance() method.
var nIndexFrom = nIndex;
var nIndexTo = nIndex + 1;
Subform3.instanceManager.moveInstance(nIndexFrom, nIndexTo);
}
else {
xfa.host.messageBox("The current item cannot be moved because it is the last
instance in the list.", "Combining Instance Manager Concepts", 1);
}
You can also write this script by using the underscore (_) notation to reference the properties and methods
of the instance manager, as shown here:
var nIndex = Subform3.index;
if ((nIndex + 1) < Subform3.instanceManager.count) {
var nIndexFrom = nIndex;
var nIndexTo = nIndex + 1;
_Subform3.moveInstance(nIndexFrom, nIndexTo);
}
else {
xfa.host.messageBox("The current item can't be moved since it already is the
last instance in the list.", "Combining Instance Manager Concepts", 1);
}
