Checkbox checked, then two other checkboxes become both unchecked and disabled/read-only

Report · Mar 08, 2018

Hi

In my pdf form I have three checkboxes named: checkbox1, checkbox2 and checkbox3.

I wish the following to happen:

If checkbox1 is checked, then checkbox2 and checkbox3 become unchecked/cleared (if they were previously checked), but at the same time checkbox 2 and checkbox3 also become disabled/read-only (by disabled I mean not checkable, not clickable, just read-only).

I have a javascript that does kind of the opposite (which I earlier got help with on this forum on a similar but different case).

It looks like this: checkbox1 checked then checkbox2 and checkbox 3 become checked and disabled/read-only.

And the script for this looks like this:

on the MouseUp script for "checkbox1".

this.getField("checkbox2").value = event.target.value;

this.getField("checkbox2").readonly = (event.target.value == "Yes");

this.getField("checkbox3").value = event.target.value;

this.getField("checkbox3").readonly = (event.target.value == "Yes");

So as a rookie I have tried to experiment with this script as a base but no solution so far.

Appreciate your help on this

It is important to work through the logic.

When you say that checking 1 causes 2 to become unchecked if it was checked, but doesn't do anything if 2 is already unchecked. The result is that checking 1 always unchecks 2. This is an important simplification when you go to write the code.

So here is a variation that only changes 2 & 3 (to unchecked) when 1 is checked, but leaves them untouched when 1 is unchecked

Notice that the export values for 2 & 3 are not used, since they are only being turned off (unchecked). The code never checks 2 & 3.

var bChecked = (event.target.value == "Yes")

this.getField("checkbox3").readonly = bChecked;

this.getField("checkbox2").readonly = bChecked;

if(bChecked)

{

this.getField("checkbox3").value = "Off";

this.getField("checkbox2").value = "Off";

}
