I can't trigger the unload event in Chrome

Question

This code runs fine on Firefox, but I can\'t make the unload event work on Chrome anymore. Did Chrome stop supporting the unload event?

This is my c

Answer 1

window.onunload = alert("Are you sure 2?");

This is incorrect. You are setting onunload to the result of alert, you need to set it to a function:

window.onunload = function(){
    alert("Are you sure?");
}

If you want to use jQuery, this will work in all browsers.

$(window).unload(function () {
     alert("Are you sure?");
});

NOTE: It might seem like it's not working in Chrome, but it is. That's because Chrome blocks alerts in the onunload event.
