Window.opener problem

I have a main window which opens a pop up window.

I was trying to use window.opener to manipulate the parent window and met with some problems. So I did some error checking and put the following code in the popup:

<script>

mywin = window.opener

alert(mywin)

self.close()

</script>

The alert, shows undefined, because of which none of my window.opener implementations worked.

Do i need to define the windows?? Whats going on here?

By the way I'm using JSP, and it has js embedded in it.

Thanks!!

keinloffel,

you're getting &quot;undefined&quot; when opening this page using window.open() from the parent? this error is to be expected if you open the window in any other way.

what browser / OS are you using?

Where is the code that you use to open the popwindow? All of this code seems to be the popwindow itself...

IE 5, Win2k.

My bad, I used <a href=&quot;popoup&quot; target=&quot;new&quot;>
and not window.open().

How can i write that with window.open() ?


Thanks

the example below will allow u to have a better control on the new window. enjoy it :)

<a href=&quot;javascript: cmdOpenWin('
function cmdOpenWin(url)
{
iWidth = 530;
iHeight = 400;
iOffset = parseInt((screen.availHeight - iWidth) * 0.6);
wOpenWin = window.open(url, &quot;wOpenWin&quot;,
&quot;toolbars=no,&quot; +
&quot;location=no,&quot; +
&quot;directories=no,&quot; +
&quot;status=no,&quot; +
&quot;menubar=no,&quot; +
&quot;resizable=no,&quot; +
&quot;scrollbars=yes,&quot; +
&quot;screenX=&quot; + ((screen.availWidth - iWidth) / 2) + &quot;,&quot; +
&quot;screenY=&quot; + iOffset + &quot;,&quot; +
&quot;left=&quot; + ((screen.availWidth - iWidth) / 2) + &quot;,&quot; +
&quot;top=&quot; + iOffset + &quot;,&quot; +
&quot;width=&quot; + iWidth + &quot;,&quot; +
&quot;height=&quot; + iHeight);
wOpenWin.focus();
}
