Javascript help

Good morning,

I have been assigned a work project that I have no idea how to do 😞  I have created a fillable form using Adobe Pro and was only able to accomplish this through the use of YouTube videos. I am new to Adobe so any help I can get is greatly appreciated.

In my form, I need to format "Field B", to become a required field if "Checkbox A" is checked. . Is there a way to do this?

Thanks!

That's not a formating issue, but here's the solution to your specifi issue.

 

Add this script to the MouesUp "Run a javaScript" action on the checkbox

 

this.getField("Field B").required = (event.value != "Off");

The solution provided by Thom will work, until you reset the form and then the text box will remain required (if it already was). I would do it a bit differently.

Assuming your text field doesn't have a calculated value, use this script as its custom calculation code:

 

event.target.required = this.getField("Checkbox A").valueAsString!="Off";

 

If it does have a calculated value you can use a different (hidden) text field to achieve it, using this code:

 

this.getField("Field B").required = this.getField("Checkbox A").valueAsString!="Off";

 

Using a calculation script instead of a MouseUp one will make sure the field is set as non-required when the form is cleared.

    This worked! Thank you so much!

    Can you please tell me how I would require 1 checkbox to be checked from a list of checkboxes? For example, "What service are you requesting?"
