Run onbeforeunload alternative if onbeforeunload not supported

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!
