I have been making some PDF for my clients for them to edit information and after that, they send it to third part but, of course, need to "lock" the PDF after using a reader version. Is it possible?

Can you explain to me how to do it with JS?


Sure. You can use this code:

for (var i=0; i<this.numFields; i++) {
    var f = this.getField(this.getNthFieldName(i));
    if (f==null) continue;
    f.readonly = true;
}

"Is it possible to reverse the read only after the scritp is run?"

Yes.

Replace this line:

f.readonly = true;

 

By:

f.readonly = false;

I know this is post is older yet it helped me do exactly what i needed at first.  Is it possible to reverse the read only after the scritp is run?  I've been unable to figure that out.

Run a similat script that sets readonly to false. Bear in mind there is no such thing as a form that can't be changed, if you are hoping for some kind of security.

You can make the fields read only using JavaScript.

With Digital Certificates you can not only lock field but also add special code to detect any changes since the signing of the form.

Depends on what commands you're using. You can set the fields as read-only in Reader using JS, yes.
