Hi all Fairly straightforward project. Some browsers don't support the javascript function onbeforeunload. It's easy to test this by seeing if [login to view URL] is defined. So if I have some code like this: [login to view URL] = function() { // do something } it will only work in browsers which support [login to view URL] I need you to change the above code so it will try the alternatives (e.g. Safari's alternative to onbeforeunload, etc.) if [login to view URL] is undefined. Your code needs to work in all major browsers, i.e. the browsers commonly used on Windows, Mac, Linux, iOS, Android. Any questions, just ask!
