[mochikit] Re: Is there any secret to connect to document.body on IE?

[Kevin Damm]

It looks like more than just IE has a problem with the onchange event.
 According to quirksmode
http://www.quirksmode.org/js/events_compinfo.html#forms
the onchange event is buggy for Safari and Opera as well, not being
implemented for some form elements.  It may be that the event doesn't
propogate to any parent elements or isn't signalled in the first
place.

An alternative event type seems to be "onblur" -- you could check the
result of a change on a form element when the user moves to a
different form element, but this would trigger even if the form
element hasn't changed.

It seems, to get exactly what you want, you'll have to trap all
relevant key and mouse events in the parent node, and use information
about which node caused the event to decide how to handle it.
