Is there a cross-browser standard on-load event for HTML's "object" tag?

I am aware that IE supports the onreadystatechange attribute on the object tag, but this doesn't seem to be a standard way thus all other browsers do not support it.

Update: To clarify, I am not looking for the DOM Load event, I am looking for the load event of the object tag itself(e.g. an object tag embedding a PDF file into a page).

In a way, I am looking for something similar to img's onload event /complete attribute for the object tag.
