Question

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…
