I have a parent/child relationship between two windows. The parent
spawns the child using something like this.
windowHandle = window.open("child.aspx","child");
the problem is that if the child window closes then the windowHandle
object is left in an orphaned state. It does't equate to null and I'm
not sure how to check and see if the window still exists. The child
does notify the parent window through the window.opener object when it
closes but this does not work in EVERY case.
I'm looking for something like "if isnothing(windowHandle)"
thanks
will
