I'm creating a FF extension that needs to detect whether a window was opened via javascript with the window.open() command. I've tried many different ways: window.opener, parent.window.opener, this.opener, etc. and it always returns null.
I was also trying it using the code editor here: http://www.w3schools.com/js/tryit.asp?filename=try_win_focus The only way that it returned a valid opener object was when I changed the line to: myWindow.document.write(myWindow.opener); However, this implies that you have to know the object reference name in order to get the opener, but there is no way that I'm aware of to detect this in a loaded website. Any ideas of how I can reliably detect if a window was opened via javascript? _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
