In JS I am using :

```
window.open('index.php?module=Contacts&action=UD_lookupemailtemplates&tempmode=userdefined&temp_url='+encodeURIComponent(temp_php_url),'emailtemplate','top=100,left=200,height=400,width=500,resizable=yes,scrollbars=yes,menubar=no,addressbar=no,status=yes')

```

To open a small window which has few links.
Now on the click on any one link an id will be attached to the a url and then I used this :

```
window.document.location.href = url;

```

This is also in JS. what this does is that it changes the contents of the small popup window but I need it to close the popup window and open this url in the main parent window from where the popup was created.  
 Is that possible ?
