Identifying events with javascript functions registered

[Ranadhir Nag]

We need to record all javascript events fired/registered against any HTML element on a form.
For example,if there is a SELECT element on a form,and there is a javascript function registered against the onchange event of the element,we need to shortlist the 'onchange' event.
How do we do this - is there some way to identify the events against which javascript functions have been registerd for any element - (either through IHTMLDocument interface or attachEvent DOM)
The purpose is to trigger that event programmatically - i.e we would populate the SELECT element and trigger the javascript 'onchange' event(or any other 'javascripted' event for that matter) through FireEvent.

You would manually have to loop through all the elements and manually test if they contain that event handler.

Thanks Eric.
By manual testing do you mean that we would actually have to fire the possible events on each element and check for the result?

Hint: alert(typeof obj.onchange)

alert(typeof(obj.on<any event> gives me 'object'.

In fact type of on any event gives me 'object' - I even tried obj.onjunk!!
