What i want is, when a user leaves or clicks back button there should be a prompt which asks him if he wants to visit another site. If he clicks yes then the page should be redirected. If clicks no then the browser closes or goes to back whatever the visitor has clicked. (x or back button) But it should not happen when user submits the form or visits internal link. please don't suggest me not to do this, i dont care if its irritating as its for my client so its my humble request to all the js pros to help me asap.
