Hi,

I have a field on an Adobe Acrobat Pro DC form that I want to show or hide based on the value of another field.

My Conditional Field is Field A.

My Controlling Field is Field B.

I only want to show Field A when Field B = X.

Otherwise, Field A is hidden.

Is there some script I can write in my form to accomplish this?

If so, can someone help me out with the code for the script? And tell me exactly where I should copy/paste this script into the form?

I appreciate the help.

George's script is exactly the right way to implement the show/hide functionality for a text field.

You can find more details (more complete info) on showing and hiding any kind of field here:

The custom validation script for Field B could be:

// Custom Validation script for Field B

getField("Field A").display = event.value === "X" ? display.visible : display.hidden;

where "Field A" should be replaced with the exact field name of that field. Note that the script won't execute until the value of Field B changes, but once it does it will control the visiblity of Field A as expected. Enter the script on the Validate tab of the Field Properties dialog.

Hi,

Thank you for the response. I copied the code as you indicated but it did not hide the field. I uploaded photos of my Field A and Field B. Including the validation script for Field A.

I only want Field A to show if Field B = 1. But Field A shows for any value of Field B.

Can you do me a favor and look over my code and tell me whether I have it correct.

Thanks again for the help.

Below are screen shots of Field A General Tab, Field A Validation Tab, and Field B General Tab.
