Menu
I've broken my problem down to the following simple code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>IE test</title>
<script src="https://code.jquery.com/jquery-1.11.3.js"></script>
<script type="text/javascript" charset="utf-8">
$( document ).ready(function() {
$('.js-click').click(function(e){
window.location.href = 'http://www.google.com/';
});
window.onbeforeunload = function(e){
return 'moving on';
};
});
</script>
</head>
<body>
<a href="#" class="js-click">Google</a>
</body>
</html>
This works as expected in chrome without warning or error, but in IE11 it throws the following error when you choose "Stay on this Page":
File: 10.0.1.126:8080, Line: 10, Column: 11
Any idea why?

Actually the error comes from:
window.location.href = 'http://www.google.com/';
And this is just speculation, but I believe the developers of IE wanted to be able to catch when the user decides not to follow the link. Thus, you can actually try-catch this block and you'll know when the user didn't get redirected (as a result of onbeforeupload).
try {
window.location.href = 'http://www.google.com';
} catch (error) {
alert("Y U NO REDIRECT");
}
If you console.log(error) you'll see that there's no error message, and the error number is -2147467259.
