- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating an interactive PDF form where users can visually select Yes or No by clicking to circle their chosen option.
- Observed behavior
- Needs a method to toggle a red circle outline around text characters using radio button field settings and JavaScript.
Ensure you have a professional PDF editor like Adobe Acrobat Pro that supports form field creation and JavaScript execution, as standard PDF readers may not support these interactive scripts.
Using Radio Buttons and JavaScript to Toggle a Red Circle
By configuring transparent radio buttons and adding a Mouse Enter JavaScript action, you can create a toggling red circle effect over your text.
This method involves placing invisible radio buttons directly over your text. We will use a short JavaScript snippet to toggle the border color of these buttons when the user interacts with them.
Open your PDF form in edit mode and create two radio buttons placed exactly over the 'Y' and 'N' characters. Assign them different group names (e.g., Group1 and Group2) so they act independently rather than being mutually exclusive.
Right-click each radio button and select 'Properties'. Under the Appearance tab, set the Line Style to 'Solid' and change the border color to 'No Color' (transparent).
Go to the 'Actions' tab in Properties. Select 'Mouse Enter' as the trigger, choose 'Run a JavaScript' as the action, and click 'Add'. Paste the following code: event.target.borderColor = (color.equal(color.transparent, event.target.borderColor)) ? color.red : color.transparent;
Close the form editing mode and test your document. Hovering or clicking over the letter will now toggle a red circle on and off.

- 3. Format the circle: Draw the circle over the 'Y' or 'N', set the fill color to transparent, and change the outline color to red to clearly mark your choice.
- 4. Save your filled document: Click 'Save' to ensure your visual selections are preserved in the final PDF document.
Frequently Asked Questions
Why doesn't the red circle appear when viewing the PDF in Chrome?
Most web browser PDF viewers, including Chrome and Edge, have restricted or non-existent support for PDF JavaScript. To ensure interactive elements work correctly, open the file in a dedicated PDF application.
Can I make the radio buttons mutually exclusive?
Yes. If you want users to select either Yes or No but not both, assign the exact same group name to both radio buttons during creation. However, the specific JavaScript toggle logic provided works best when they act as independent buttons.
Is it possible to use a different color for the circle?
Absolutely. You can modify the JavaScript code by replacing 'color.red' with another supported color property, such as 'color.blue' or 'color.green', depending on your design preferences.
