javascript - Load events for embedded elements

Question

If I do an online onload event for embedded objects, that seems to work but I can't seem to get the load event working through addEventListener. Is this expected?

Answer 1

Probably, but it may be browser dependent.

windows and images and iframes define their load events with addEventListener and attachEvent, but other load events are browser specific.

A script or link element's onload doesn't attach in IE, for instance.
