javascript - Check if a popup window is closed

Question

I am opening a popup window with

var popup = window.open('...', '...');

This javascript is defined in a control. This control is then used from a web page. I want to reload the page which opens this popup when the popup is closed.

Basically user is required to input some denominations in the popup window and submit. These denominations are then stored in user sessions. And when user clicks submit I am closing the popup window and at the same time want to refresh the window which opens this popup to refetch the updates which user made in the popup.

I am trying to do

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

I guess I am doing it wrong coz this isn't seems to be working.

For testing the issue I've even tried this but no alert appeared.

if (popup) {
  popup.onclose = function() { 
    alert("1.InsideHandler");
    if (opener && !opener.closed) { 
      alert("2.Executed.");
      opener.location.reload(true); 
    } else { 
      alert("3.NotExecuted.");
    }
  }
}

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);
