Window Part 2

Okay, if you know the name of the window, what is the code to close that window from another window? For example: Mainwindow, 1st windown, 2nd window. Now from the 2nd window, how can I close the Mainwindow? Again, thanks for your help.

if the mainwindow has opened the 2nd window...

opener.close()

if the 1st window opened the 2nd window then opener.opener.close()

and so on...

in order to prevent the "Are you sure..." confirmation box in IE, put this code at the top of the mainpage...

<script type="text/javascript">
<!--
window.opener=self
// -->
</script>

it fools the window into thinking it is was opened by another window and will close without the confirmation.
