Im trying to make a website like the button game that goes on and on
So far what i have is the exit pop up message -_-
but i dont know how to make another message after it!
For example :

"Hello, to exit please click on ok"
[ok] [cancel]
*Clicks ok*

"Oh im sorry did i say ok? i ment Cancel!
Click Cancel to exit"
*Clicks Cancel*
This could go on and on-

Also is there a way to insert a link in that exit pop up message?

So far i have this exit pop up message

<script type="text/javascript" language="javascript" >

var internal = 0;
function bunload() {
if (self.parent.frames.length && self.parent.frames.length != 0) self.parent.location = document.location;
neva =alert(" You are about to leave my site! :O);}

  if (internal != 1) {
   window.onbeforeunload = bunload;
   else {
   internal = 0;
	if(links[i].getAttribute('rel') == 'external'){{}}}}
