Kill unload function in JS?

Question

Is there a way to kill the unload function with javascript(jquery)?

I am looking for something like this:

window.onbeforeunload = function(){
    confirm("Close?")
}

or in jquery:

$(window).unload(function() {
    confirm("close?")
});

Now, on window unload I get my confirm alert but it will continue in any case. Clicking cancel it won't stay on my page.

Answer 1

the function has to return false to abort or true to continue, so you cauld simply return the confirm like this:

window.onbeforeunload = function(){
   return confirm("Close?")
}
