Nope. Sorry, but the underlying browser stuff doesn''t allow it. If you use the W3C event model (multiple event handlers per event type per element), you can add listeners, and remove them by reference to the function, but there''s no way to iterate over the list of listeners, AFAIK. Prototype''s Event.observe() is essentially a cross-browser wrapper over Mozilla''s addEventListener() and IE''s attachEvent(), which are the implementations of the W3C event model. The best you could do is to hack Event.observe() and stopObserving() to maintain a list of listeners alongside the calls to the browser functions, which would work so long as you never called the browser functions directly.

Thanks, i know this method, but i need to remove all event handlers
for an element (without specifying a handler). Something like this:
YAHOO.util.Event.removeListener("myelementid", "click");
(http://
developer.yahoo.com/yui/event/)
Because i don''t have reference to the event handlers attached to the
element before.
Or is possible to get references to all handlers for an element?

I''m not sure if this is possible with the current version. But my understanding is, that it would be possible with 1.6: *The event name and handler arguments to Event.stopObserving and Element#stopObserving are now optional*, so for a given element, you can now quickly unregister all its handlers, or unregister all handlers for a single event. I have not experience with it though.
