I was recently putting together an application. My test user did something I wasn't expecting. Rather than using the buttons within the application, he went for the browser buttons. It prompted me to provide a warning for the user that the application wouldn't work so well if he did this. See code below:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Test page</title>
<script src="http://www.google.com/jsapi"></script>
<script>
google.load("jquery", "1");
</script>
</head>
<body>
<a href="index2.php">Go to page 2</a>
<script>
(function()
{
catchBrowser = true;
$('a').click(function()
{
catchBrowser = false;
});
$(window).bind('beforeunload', function()
{
if(catchBrowser == true)
{
return 'Please use only the buttons within the application pages.';
}
else
{
return;
}
});
})();
</script>
</body>
</html>
