I want to create a child window by using window.open(...) and do some manipulation on the new window AFTER it is fully loaded. Is there a way so that the parent window can tell if the child window have finished loading? I have no control on the page loaded in the child window so I cant rely on the child window document setting some flag to true in its onload handler.

Well some browsers support readyState
create a setTimeout that loops until
For other browsers that do not support it, you can loop until you detect an object or JS variable on the page.
