As you know that a window can be closed via method window.close()
But when this method is used, then it warns the user that window is being closed. Now its on the will of the user what he wants. But I have seen some sites where there is a buttton with a label "Close" when clicked, It closes the window very quitely, and doesnt asks the user.
My question is that how this is made possible?
(Please give me some code about it!)
