I got a problem with JavaScript. I want a script that will pop-up on exit whole web-site a message with question and if visitor answers "NO" web page closes and if he answers "YES" he will be redirected to another page. I found a example at http://www.pgrs.net/2008/01/30/popup-when-leaving-website/ but it seems that it doesnt work for me. I couldnt find any solution. Pleae check my code and tell me maybe i'm doing something wrong ? Here`s my source code.
Maybe somebody will see a problem.
<!DOCTYPE html>
<html lang="lt">
<head>
<meta charset="utf-8">
<title>PUA.LT</title>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="description" content="">

<link rel="stylesheet" href="<?php echo base_url("additional/style.css") ?>">
<script src='<?php echo base_url("additional/prototype.js")?>' type='text/javascript' ></script>
</head>
<body>
<script type="text/javascript">
Event.observe(document.body, 'click', function(event) {
if (Event.element(event).tagName == 'A') {
staying_in_site = true;
}
});
window.onunload = popup;
function popup() {
if(staying_in_site) {
return;
}
alert('I see you are leaving the site');
}
</script>
</body>
</html>
Try this:
window.onbeforeunload = popup;
function popup() {
return 'I see you are leaving the site';
}
