jQuery detect click on disabled submit button

The best way I've found to do this is to use a "disabled" class to disable the button. You can then catch click events normally in jquery. If $(this).hasClass('disabled'), you do your 'jazzy indication' stuff, along with event.preventDefault(); Once the user has done their thing, you can removeClass('disabled') from the input[type="submit"] 'button'. Easy!

Found this in this question -

Firefox, and perhaps other browsers, disable DOM events on form fields that are disabled. Any event that starts at the disabled form field is completely canceled and does not propagate up the DOM tree. Correct me if I'm wrong, but if you click on the disabled button, the source of the event is the disabled button and the click event is completely wiped out. The browser literally doesn't know the button got clicked, nor does it pass the click event on. It's as if you are clicking on a black hole on the web page.

I'd thought you might be able to 'fake' a click by wrapping the button in a div and firing the logic on the div's click event. But, as indicated above, the events on disabled elements do not seem to be bubbled up the DOM tree.

You could put a div around the submit button and attach a click function to that for when the submit button is disabled:

<div id="sub-div"><input type="submit"><div>

$('sub-div').click(function(event){
    if (attr('submit-button', 'disabled') == 'true')
    {
        alert('Button Disabled')
    }
});

This is just code from the top of my head, so it might not be exactly right. But you get the point.
