How to disable the save button in a form is no changes was made.

EDIT:

Never mind... just figured out that a a simple JQuery hack would do (by adding it to my custom.js)

        $(".save").prop("disabled",true);
        $("form").on("change", ":input",
            function(){
                $(".save").prop("disabled",false);
            }
        );

Yup, that's pretty much exactly the code I would have suggested.

There are some corner cases where stuff can get changed without a 'change' event getting fired, but hopefully you won't run into any.

But you should use jQuery() instead of $()
