How to suppress IE9 window.close() confirm message

Question

After applying the window.close function IE9 raises the "The webpage you are viewing is trying to close ..." message. Is there a way to suppress this message without changing the application code, but by changing some IE-specific registry entries instead?

Answer 1

IE doesnt allow to close the window without confirmation if the window was not opened by script
U can try this ...
window.open('', '_self', '');
window.close();
