Javascript onbeforeunload return value

I finally found out what is causing one hell of an issue for me.

I am accessing and modifying the have javascript via vb.net, but i only need help with the javascript.

The document calls 

window.onbeforeunload = function() {return "ANNOYING TEXT" };

So lets so what can i modify the return value to so that it does not return anything.

Return false, null and 0 do not work.

I DO NOT HAVE ACCESS TO THE JAVASCRIPT.

Here is the callee:

$(window).bind('beforeunload' ,function() {
      return 'Warning!\nIf you leave, you will cancel the installation of ' + 'SOME BULLSSHIT';
    });

I know i can not delete the function, i just need it to be disabled. or disable its parent callee.

Solution

  • You can use window.onbeforeunload = null; to unbind using vanilla javascript

    or $(window).unbind('beforeunload'); using jQuery.
