I see two possible problems with your code.

I believe that IE returns null if the mouse is outside the browser's client window when the event fires. Your conditional would therefore evaluate to false.

Also, if you are closing the browser by clicking on the Exit button, then window.event.clientX would be a positive value, as you are to the right of the 0, 0 point.

Solution 2

hi,

Try this lines for that.

JavaScript

  $(document).ready=function(){
    window.onunload=function(){alert("dfgfdg");};
};

I hope it works for you also

All the best
