Which YUI Event Listener?

The Accessibility toolbar for Firefox has a feature for developers that presents a list of the event handler attributes for each element on the page. The problem is that using attributes to set events is nasty and the YUI Event library instead attaches a singleton listener to the window which isn’t shown. This main YUI listener then delegates to YUI Event listeners which are created.

In order to get something like the functionality in the accessibility toolbar for YUI Event library listeners I’ve made a bookmarklet that uses some of the functionality of the YUI Event library. The YUI Event List Bookmarklet will show you a list of all the elements on the page that have listeners attached and what those listeners are. You can also view the functions that will be called when the event fires. It’s perfect for tracking down that elusive listener that’s using event propagation to hook onto stuff.
