When checkbox is checked, disable other checkboxes

[dennisg19059968]

Hi,

I've read an earlier discussion about disabel checkboxes but the discussion was to advanced for a rookie like me,

so please, in a very beginner-friendly way, please explain with a javascript how to do the following:

(In Adobe Acrobate DC I'm doing a fillabe form.)

There are three checkboxes named: checkbox1, checkbox2 and checkbox3.

I wish the following to happen:

When checkbox1 is checked:

• then checkbox2 and checkbox3 become disabled (by disabled I mean the checkboxes become not checkable/not clickable)

          and

• also at the same time checkbox2 and checkbox3 become unchecked if they were earlier checked.

Thanks

/Dennis

A custom JavaScript for the "Mouse Up" action:

// set readonly property based on the value of this field compared to "Off";

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

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

Thanks a lot gkaiseril,the script is working well .

Is it possible though to get checkbox2 and checkbox3 unchecked (if they were previously checked) when they become disabled by checking checkbox1?
