<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript" language="javascript">
var validNavigation = false;
function endSession() {
// Browser or broswer tab is closed
// Do sth here ...
alert("bye");
}
function wireUpEvents() {
/*
* For a list of events that triggers onbeforeunload on IE

*/
window.onbeforeunload = function() {
if (!validNavigation) {
endSession();
}
}
// Attach the event keypress to exclude the F5 refresh
$(document).bind('keypress', function(e) {
if (e.keyCode == 116){
validNavigation = true;
}
});
// Attach the event click for all links in the page
$("a").bind("click", function() {
validNavigation = true;
});
// Attach the event submit for all forms in the page
$("form").bind("submit", function() {
validNavigation = true;
});
// Attach the event click for all inputs in the page
$("input[type=submit]").bind("click", function() {
validNavigation = true;
});
}
// Wire up the events as soon as the DOM tree is ready
$(document).ready(function() {
wireUpEvents();
});
