check if a window has closed, inside of a iframe

So i am building a 'like' button but i have a small problem after the user login's in through the little window, the user has to refresh the whole page. I want it to check if the window has closed and then refresh the iframe. So I have this code to open the pop-up and i've been looking at the at this post for help, but it's not helping that much. Check if a popup window is closed

function grubber_highlight()
            {           
                    var popup = window.open("http://www.grubber.co.nz/login/", "newwindow", config="height=600,width=800, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, directories=no, status=no");
                        var windowloc = document.URL;
                        var windowlocation = (windowloc + "&highlight=t");
                        window.location = windowlocation;   
                        if (popup) {
                          popup.onclose = function () { alert("closed"); }
                        }                   
            }

I have this code to check if the window has closed and then alerts me that it has worked

                   if (popup) {
                        popup.onclose = function () { alert("closed"); }
                    }

The little window goes here http://www.grubber.co.nz/login/ if anyone want's to know.

I also want it to be able to work on most browser newer that ie8

edit I googled a but deeper and found onunload it works on the closing but it also fires up when i open the window also...

Question

how to detect when the window is closed and then refresh the iframe

Supposed this is how the popup is opened:

win = window.open(...);

Then, you should repeatedly check if the popup is closed.

var timer, win;
function polling(){
 if (win && win.closed) {
   clearInterval(timer);
   alert('popup window is closed.');
 } 
}
timer = setInterval('polling()',100);

UPDATED: Another technique is discussed here

Ok thanks guy's but i go the answer i wanted with the onunload event

     var popup = window.open("http://www.grubber.co.nz/login/", "newwindow", config="height=600,width=800, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, directories=no, status=no");
var windowloc = document.URL;

var e = 0;  
if (popup) {
     popup.onunload = function () {
        if (e == 1)
        {
         //this will reload the iframe
        alert("closed");
         }
        else
        {
          //this will be when the pop-up gets created
        e++;                                    
        }                         
}
