    The close event is executed when a request has been made to close the window when the user presses the close button.

    If an event handler is placed on the window element, it can be prevented to close (see example below). Note that the close event is only fired when the user presses the close button on the titlebar; (i.e. not File -> Quit). The unload event should be used to capture all attempts to unload the window.
