removeEventListener when you don't know the object or function name

[Andrew Poulos]

Is there a way to call removeEventListener when you don't know what
events may have been added?

With something like
object.onclick = blah;
I could run through every element in the page, search for onclick and
set it to null.

When people use addEventListener and don't keep a record of the events
they add it to I don't know how to find them.

No. You could try to override the addEventListener function before any
listener is added and use that information, or you could generate a list
of "all" probable event names and use them all, but other than that this
is not possible. Browser-internal APIs might help you, if this is for a
browser extension of some sort.
