a simple .html file test if code in onbeforeunload works.

<!doctype html> <html lang="en"> <head>     <meta charset="utf-8">     <script>         window.onbeforeunload = function () {             alert('are sure');         }     </script> </head> <body>     <div id="container">         <p><strong><a href="http://stackoverflow.com/">go stack overflow</a></strong>. lorem ipsum dolor sit amet, consectetur adipiscing elit. maecenas laoreet imperdiet diam, in sodales velit porta eget.</p>     </div> </body> </html>

if (localstorage.scrollpos != undefined)     $('#container').scrolltop(localstorage.scrollpos);  window.onbeforeunload = function () {     localstorage.setitem("scrollpos", $('#container').scrolltop()); };
