How to Get Text Instead of Numbers from an Acrobat JavaScript Dialog
Question details
The user needs to retrieve the actual text (like a fruit name) selected in an Acrobat JavaScript dialog popup instead of its numeric export value.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Running a custom Acrobat JavaScript using the execDialog method with a popup list or dropdown menu.
- Observed behavior
- The dialog script returns the numeric export value associated with the item instead of the selected text string.
Ensure you have access to the JavaScript console in your PDF editor and are familiar with the basic structure of the execDialog method.
Parse the Popup Selection for Text Identifiers
Modify your dialog result handling to capture the string text associated with the popup selection instead of defaulting to the numeric export value.
In an execDialog popup, the numeric values typically represent the export values of the various items. A positive value often indicates the item selected by default. To get the text, you must target the popup item identifier rather than the numeric value.
Recognize that calling elements directly (like elements[i]) will return the numeric export value of the selected popup item.
Instead of using the export value, modify your script to retrieve the popup item identifier, which holds the actual text string of the selection.
Use the extracted text string when assigning the result to your target field (e.g., this.getField("Text1").value = selectedText;) rather than passing the numerical index.
Review Example 3 in the official Acrobat documentation for the execDialog method to see the exact syntax for correctly parsing the selected value of a popup field.

You can refer to the official Acrobat JavaScript API Reference. Specifically, Example 3 under the execDialog method documentation demonstrates how to correctly parse the selected value of a popup field.
Does WPS Office support editing interactive PDF forms?
