Make text fields read only based on content selected in a drop down

Question

I have a form on which I want to make some text fields Read-Only if a certain value is selected in the drop down menu of another field. I've tried:

if (this.getField("Combo Box 9").valueAsString = "Reprint") {

this.getField("Text Field 42").readonly = true;

}

Somehow the field becomes read-only by default then.

So the code only changes the field to ReadOnly, not back, but it also contains an error. The code below fixes the issue.

But, since you've been trying different variations of code you may have bad code lying about in the form. Make sure all of the test code is removed. Then use this script in the "Validation" script for the "Combo Box 9" field, which is where this kind of script is supposed to go:

this.getField("Text Field 42").readonly = (event.value == "Reprint") ;

For clarity, I've been trying a few things. I have the following as a custom format in the field I want to be readonly:

if (this.getField("eSample").item = "Reprint") {
this.getField("CoreColor").readonly = true;
}

That made the CoreColor field readonly immediately (regardless of the value in eSample). It seems like my condition isn't being read, but the action is executed anyway.
