I then stumbled upon a stackoverflow question in which someone was having a similar issue.

Enter Visual Event 2. VE2 is an open source bookmarklet that, when loaded, will highlight all of the objects with events on a page and show you what scripts will be called when they are clicked. This thing is absolutely brilliant. I was instantly able to see what script was being called and found it in seconds. Better still, since it’s a bookmarklet, it should work in most modern browsers too!

This thing will permanently live in my developer toolbox. I highly suggest it for developers working on sites that are js intense.

Visual Event 2 Website

(function($){
  $.fn.thickbox = function( options ) {  
	  var settings = $.extend( {
		  'title' : '',
		  'href' : '',
		  'group' : false,
		}, options);
    return this.each(function() {
        if ($(this).hasClass('hasThickbox') == false) {
            var $elem = $(this);
            $elem.click(function () {
                var t = settings.title
                var a = settings.href;
                var g = settings.group;
                tb_show(t, a, g);
                this.blur();
                return false;
            });
            $elem.addClass('hasThickbox');
        }
    });
  };
})( jQuery );

I’ve kept it largely the same as it was in its original form so that others can easily see how it works and so that there aren’t too many modifications to the original logic. The function expects the options: Title, href, and group. All 3 work the same way as they did with the original plugin, and the options for Thickbox are still supplied as a query string through the href option value (see herefor an explanation of the query string options).

There are still many things that I’m not particularly fond of with Thickbox, but if you’re being forced to use it, this will at least provide you with a little bit less of a hassle.
