You are looking for the beforeunload event.

For example:

function someCloseEvent() {
  return "Any string value here forces a dialog box to \n" +
         "appear before closing the window.";
}

window.onbeforeunload = someCloseEvent;

Answer 2

or the onUnload? -> http://www.w3schools.com/jsref/jsref_onunload.asp

Answer 3

You will get unload message during refresh also. Better to check clientx and clientY also in the beforeunload. This is a pseudo code...

<script type="text/javascript">

 var myclose = false;

 function ConfirmClose()
 {
  if (event.clientY < 0)
  {
   event.returnValue = 'Any message you want';

   setTimeout('myclose=false',100);
   myclose=true;
  }
 }

 function HandleOnClose()
 {
  if (myclose==true) alert("Window is closed");
 }
</script> onbeforeunload="ConfirmClose()" onunload="HandleOnClose()"

Answer 4

there isn´t a good form to do that,

try this codes above, and press alt+f4.

On a side note, I would seriously consider whether you want to do this. When I close the window, I'm done with your site, I don't want any more messages from you. Popping up an extra window is going to annoy a lot of people.
