How to Copy Text Between Acrobat PDF Fields Using JavaScript
Question details
The user needs to understand whether Acrobat JavaScript supports standard clipboard copy and paste for transferring text and attributes between PDF fields, and how to successfully transfer these values.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Developing or customizing interactive PDF forms that require duplicating or passing user input from one text field to another automatically.
- Observed behavior
- Standard clipboard copy-and-paste methods are unavailable in PDF JavaScript, requiring a scripting alternative to pass values between fields directly.
Ensure you have access to the PDF form editing mode and the JavaScript console in your PDF editor to apply and test the necessary scripts.
Programmatically Pass Values Using PDF JavaScript
Use the getField() JavaScript method to manually assign the value and attributes of a source field directly to a destination field.
Because PDF JavaScript operates within a secure environment, it does not provide access to the operating system's standard clipboard copy-and-paste functions.
To duplicate information across a document, you must use scripting to read the property from the source field and assign it directly to the target field.
Open your PDF document in your advanced PDF editor and enter the Form Preparation or Editing mode.
Check the exact names for both your source and destination text fields (e.g., 'Field A' and 'Field B').
Open the properties of the destination field and navigate to the calculation or custom JavaScript action tab.
Insert the following script to transfer the text content: this.getField("Destination").value = this.getField("Source").value;
To copy other formatting attributes, add separate assignment lines for each property. For example, use this.getField("Destination").textColor = this.getField("Source").textColor; to match the text color.

Frequently Asked Questions
Why can't I use traditional copy and paste commands in Acrobat JavaScript?
PDF JavaScript executes in a secure, sandboxed environment. To protect user privacy and system security, it is restricted from automatically accessing the operating system's clipboard to execute background copy or paste commands.
Does assigning a PDF field's value also transfer its formatting attributes?
No. When you use the '.value' property, you are only transferring the raw text string. To copy formatting attributes like text color, font size, or alignment, you must assign those specific properties individually.
How do I trigger the JavaScript to transfer the text automatically?
You can set the JavaScript code to execute on specific triggers. Common methods include using an 'On Blur' event for the source field (so the transfer happens when the user clicks away) or adding the script as a custom calculation on the destination field.
