Question details
The user needs a way to automatically update the tooltips for duplicated PDF form fields so that each row has a unique accessibility description.

- Device & OS
- not provided
- Scenario
- Duplicating existing form fields to create multiple rows or identical elements within a single PDF document.
- Observed behavior
- Duplicated form fields receive unique field names automatically, but they retain the exact same tooltip as the original field, resulting in identical and incorrect accessibility descriptions across different rows.
Before running any batch scripts to modify your form fields, ensure you have finalized the form layout and saved a backup copy of your PDF document.
Use JavaScript to Automatically Assign Field Names as Tooltips
Execute a short JavaScript snippet within your PDF editor to loop through all form fields and automatically set their tooltip (userName) to match their unique field name.
This method is highly efficient for forms with numerous duplicated fields. It leverages the internal JavaScript engine of advanced PDF editors (like Adobe Acrobat) to overwrite the cloned tooltips with the newly generated unique field names.
In your PDF editing software, navigate to the 'Tools' menu, select 'JavaScript', and open the 'Document JavaScripts' or 'JavaScript Debugger' console.
Copy and paste the following code into the console: for (var i = 0; i < this.numFields; i++) { var f = this.getField(this.getNthFieldName(i)); if (f) f.userName = f.name; }
Run or evaluate the script. The system will instantly iterate through every field in the document and replace its tooltip with its specific field name.
Export and Batch Edit Tooltips Using a Text File
For complex forms requiring customized descriptive tooltips rather than just identical field names, export the form field data, edit it externally, and re-import.

Frequently Asked Questions
Why do duplicated PDF form fields share the exact same tooltip?
When you duplicate a form field, the PDF editor creates an exact clone of the original field's properties. While the software typically auto-increments the internal field name to prevent logic errors, the descriptive tooltip property remains an exact copy until it is manually or programmatically updated.
Are unique tooltips strictly necessary for PDF form fields?
Yes, tooltips serve as the accessible name for screen reading software. If multiple fields share the exact same tooltip, visually impaired users will hear identical descriptions for different inputs, making it difficult to understand what information is required in each specific row.
Can I undo a JavaScript execution if it incorrectly modifies my tooltips?
In most PDF editing software, actions executed via the JavaScript console cannot be undone using the standard 'Undo' shortcut (Ctrl+Z or Cmd+Z). This is why it is crucial to save a separate backup copy of your PDF form before running any batch processing scripts.
