Fields inactive until checkbox is checked

[SpimGim]

Looking for a way to keep a set of fields inactive (not fillable, read-only etc) until a single checkbox is checked. I have pretty much an entire page that does not need filled in unless someone would check a box for that option.

Thanks

Use this code as the Mouse Up event of the check-box:

var fields = ["Field1", "Field2", "Field3"];
for (var i in fields) {
    var f = this.getField(fields);
    if (event.target.value=="Off") {
        f.readonly = true;
        f.value = f.defaultValue;
    } else {
        f.readonly = false;
    }
}

Adjust the names of the fields in the first line to match those in your file, of course.

Can't get that script to work. Any suggestions?

I've managed to understand the rest of the code except for one line.

What is 
for (var i in fields)

What does the 'i' refer to?

Actually I just noticed it does work, but it's doing the opposite. Its only making them inactive when the box is UNchecked.

Are you sure you placed it where I indicated?

[SpimGim]

Yes, at least I think so...

Does the export value of the checkbox affect the script? Mine is set to YES

[try67]

Sorry, I misunderstood how you wanted it to work.

Simply change line #4 from:

if (event.target.value=="Off") {

to:

if (event.target.value!="Off") {

This script was working till I added some additional field names to it. I'm getting the below error. Can you tell me what I need to do? I appreciate your help!

You probably missed a comma or something like that. Post the code as text, not as an image.

Sorry. Think I found it. Missed a " mark.

Again, thank you for your assistance. Very helpful
