jQuery beforeunload事件未在任何浏览器中触发

Question

It's not firing when I close the browser. I have researched the issue a lot and found similar kinds of solution, but it is still not working.

$(document).ready(function(){
    $(window).bind("beforeunload", function() { 
        return confirm("Do you really want to close?"); 
    })
});

Answer 1

You can achieve this by using below piece of code.

$(window).on('beforeunload', function(){
  return confirm("Do you really want to close?"); 
});

If you want to perform some other things after user clicks yes, you can write that under

  $(window).on('unload', function(){
 //DoSomething
 });

Answer 2

I normally just use this:

(function($){
    $(window).on("beforeunload", function() { 
        return true;
    })
})(jQuery);
