Ever wondered how to close that damn browser window without getting a warning from the browser ?.
Well, I've gone through that many a times before when trying to close a window(subject) from either the main window or any other window which did not create the subject.
and…and i remember the solution, which i had devised for IE. (not sure about other browsers and I'll leave that for you ).
You have to remember, the window.open method creates a reference to the window.opener ?? (Hint, Hint! )
//removes the previous window.opener reference and
//tricks the browser not to display the annoying warning message.
window.opener = ‘fake’;
