Check if a popup window is closed

Here's what I suggest.

in the popup you should have:

<script type="text/javascript">

function reloadOpener() {
  if (top.opener && !top.opener.closed) {
    try {
      opener.location.reload(1); 
    }
    catch(e) {
    }
    window.close();
  }
}
window.onunload=function() {
  reloadOpener();
}
</script>

<form action="..." target="hiddenFrame">
</form>
<iframe style="width:10px; height:10px; display:none" name="hiddenFrame" src="about:blank"></iframe>

then in the server process you can return

<script>
   top.close();
</script>

Old suggestions

There is no variable called popup in the popup window. try

var popup = window.open('...','...');
if (popup) {
  popup.onclose = function () { opener.location.reload(); }
}

or with a test:

popup.onclose = function () { if (opener && !opener.closed) opener.location.reload(); }

PS: onclose is not supported by all browsers

PPS: location.reload takes a boolean, add true if you want to not load from cache as in opener.location.reload(1);

Try this:

window.opener.location.reload(true);

or

Into the popup before closing

window.opener.location.href = window.opener.location.href;
window.close();
