Newbie needs help with child windows

[Richard]

How can I tell when a child window, ie. w = window.open(...), has
completely loaded it's content?

If a child window creates a child of its own, ex. a popup, how can I
tell?

Thanks

Have it tell you that it's loaded, via it's onload event handler.
Ideally, though, you should avoid caring (and even avoid creating
child windows). What is it that you want to do when the window
has opened, that it can't do better itself?

Again, have it tell you that it has done so.

Unfortunately, I've no control over the contents of the child, so
that's not an option. I've got the original window.open handle but
after the child loads it does not appear to be a permisible reference
to the child window (behavior varies with the browser, but I can not
get or set the child status line for example).

Again, have it tell you that it has done so.

Ditto.
