Both the parent and child windows can cross-communicate with each other. The
method you're using in your code - window.opener - looks fine.

Hi Rob,
It is possible for separate windows to communicate with each other.  In an
app I am currently working on I fire upa window which contains a map image.
When the user clicks on the map I update x/y coordinates in the window
behind.  This is done using the window.opener attribute, as follows:
 
This snippet is in the pop-up window:

 
<script language="javascript" type="text/javascript">  function
setXYForMap(e) {
 
  var form = document.popupForm;
  var elem = document.getElementById('map');
  var x = 0;
  var y = 0;
  if (document.all) {
   x = (e.x - elem.offsetLeft);
   y = (e.y - elem.offsetTop);
  } else {
   x = (e.pageX - elem.offsetLeft);
   y = (e.pageY - elem.offsetTop);
  }
  // Assign these values to the original page.
  window.opener.document.getElementById('x_coord').value = x;
  window.opener.document.getElementById('y_coord').value = y;  } </script>
 
===========================================
This snippet is in the parent window.  I haven't tried this but the popwin
javascript variable should allow me to manipulate the pop-up window:
 
var popwin; // Popup window.
function closeWindow() {
 if (popwin && popwin.open && !popwin.closed) {
  popwin.close();
 }
}
function openWindow(url, width, height, target, offset) {
 
 var displaywidth = width;
 var displayheight = height;
 var offsetWin = (offset)? offset: 0;
 var x = 200 + offsetWin;
 var y = 150 + offsetWin;
 
 var parms = ('height='+displayheight+',width='+displaywidth
   + ',resizable=yes,status=no,toolbar=no,'
   + 'menubar=no,location=no,scrollbars=yes, '
   + 'screenx=' + x + ', screeny=' + y + ','
   + 'left=' + x + ',top=' + y);
 
 if (target) {
  window.open(url, target, parms);
 }
 else {
  closeWindow();
  popwin=window.open(url, null, parms);
  if (popwin && popwin.open && !popwin.closed) {
   popwin.focus();
  }
 }
}
