How to Debug Acrobat PDF Form Scripts for Copying Addresses
Question details
The user needs to troubleshoot a malfunctioning PDF form JavaScript intended to auto-fill shipping fields with billing information when a checkbox or radio button is selected.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating or editing an interactive PDF form with an auto-fill script for addresses.
- Observed behavior
- The JavaScript code fails to execute properly, preventing the billing information from copying over to the shipping fields.
Ensure you have the exact names of both the billing and shipping fields in your PDF form, and prepare to use the built-in JavaScript Console for troubleshooting.
Use the JavaScript Console to Identify Syntax Errors
The built-in JavaScript Console is the primary tool for catching syntax issues and runtime errors in your PDF form scripts.
Often, a script fails silently without alerting the user. By keeping the console open while interacting with the form, you can instantly see exact line numbers and reasons for script failures.
In Adobe Acrobat, press Ctrl+J (on Windows) or Cmd+J (on Mac) to reveal the interactive JavaScript Console window.
With the console open, click the checkbox or radio button on your form that is supposed to trigger the address copy.
Read any red error text generated in the console. Look specifically for 'SyntaxError' or 'ReferenceError' to pinpoint where your code is failing.
Verify Exact Field Names and Code Syntax
Scripts frequently fail due to incorrectly referenced field names, particularly if the code was pasted from a different form or uses spaces incorrectly.
Check Script Placement and Event Triggers
The script must be bound to the correct field and the correct interaction event to execute properly.

Frequently Asked Questions
Why doesn't my copied PDF script work in a new form?
Copied scripts rely on the exact field names from the original form. You must manually update all `getField()` text references in the copied code to match the exact names of the text fields and checkboxes in your new document.
How do I handle PDF field names that contain spaces in JavaScript?
You cannot use dot notation for field names with spaces (e.g., `this.My Field`). Instead, you must use the getField method with a string wrapped in quotes, like this: `this.getField("My Field").value`.
Which event should trigger my address copy script in Adobe Acrobat?
It is generally best practice to attach your JavaScript to the 'Mouse Up' event of the checkbox or radio button. This ensures the script executes immediately and reliably after the user finishes clicking the control.
