How to list all registered events of a DOM node using Javascript?

Question

I can add or remove an event handler for a DOM node. Is it possible to find out all the registered events handlers of a given DOM node? I am referring to straight Javascript meaning no frameworks or toolkits like jquery, dojo, Prototype, GWT, etc. If the answer is no, any reason why? Security issues?

Answer 1

DOM Level 3 specifies eventListenerList - however, I'm not aware of any DOM implementation which supports this - or any other reliable way to list the event listeners. It seems to have been an oversight to this point.
