I got a JForm and I got some fields in there. I would like to disable a field, if the value of another field is "0". I know that I can do that by preparing the form while loading, but I want to solve that "live", so if the user clicks around, the readonly should immediately be set or unset.
How can I solve this? I guess I have to do some JQuery - unfortunately I do not have any idea of jQuery and this stuff, so maybe you could help me out?
Thanks in advance :-)
