Do you know what to expect? The warnings will only show up if you have entered data into a textbox and then try to navigate away from the page. If that's not working, check the page source to see if the javascript functions are loading into the head section. This should be somewhere in the head:
<script type="text/javascript">
jQuery("document").ready(function() {
jQuery("form").submit(function(event) {
window.onbeforeunload = null;
});
window.onbeforeunload = function(event) {
var content = false
jQuery("textarea:visible").each( function() {
if(this.value) {
content = true;
return false;
}
});
if (content)
return "You have entered text; are you sure you wish to leave this page?";
}
});
</script>
