Same window twice

If I load an onload="popup();" in a body tag, I can get a popup window to show fine when the page loads, but when I refresh the page without closing the popup, it makes a new popup window instead of bringing up the old one again with the url. What can I do to use the same window?

Thanks,

Tony

Use a cookie to check whether the user already came and a window was opened for him.. if so, ignore the commands to open the pop up...

I believe you can just do an if(){ condition to check for a child document, something like

Code: 
if(!document.children['window_name']){
   window.open(etc....);
}

I'm not sure of the exact syntax, but this is the general idea.

I couldn't get that to work,

I'm not good with java script, but it's a lot like perl syntax so I usually do ok, could you help me out a little more.

This is what I have so far.

print qq~
<html>
<head>
<SCRIPT language=&quot;JavaScript&quot;>
<!--
function winscroll(URL, width, height) {
var now = new Date();
if(!window.child.popup){
var remote = window.open(URL, &quot;popup&quot; + now.getTime(), &quot;width=&quot; + width + &quot;,height=&quot; + height + &quot;,toolbar=0,location=0,directories=0,resizable=1,status=0,menubar=0,scrollbars=0&quot;);
}
// if(navigator.appVersion.indexOf(&quot;MSIE 3&quot;) < 0)
// remote.focus();
}
defaultStatus = &quot;&quot;;

// -->
</SCRIPT>
</head>
<meta HTTP-EQUIV=&quot;REFRESH&quot; CONTENT=&quot;20&quot;>
~;
#####
#End Javascript: - perl code
#####
if ($res[4] eq &quot;yes&quot;){
print qq~
<body onload=&quot;winscroll(' 620, 360);&quot;>
</body>
</html>
~;


It's a mix of perl and java, the perl generates the java, and you can see that it refreshes every 20 seconds. That's why if $res[4] my variable in perl , is == to something, it will write the body tag. That's why it pops a new window up every 20 seconds. My popup name is &quot;popup&quot;. Is there anything else you can think of?

Thanks A lot Mate,

Tony

Do you mind showing me the syntax you used? I was trying to check the documentation at developer.netscape.com and at msdn.microsoft.com/ie, but I wasn't getting anything useful.

Sure, I'm sure you already knew about this though

<SCRIPT language=&quot;JavaScript&quot;>
<!--
function winscroll(URL, width, height) {
var win = window.open(URL, &quot;popup&quot;,&quot;height=&quot; + height + &quot;,width=&quot; + width + &quot;,top=0,left=0,scrollbars,resizable&quot;);
win.moveTo(0, 0);
win.focus();
}
// -->
</SCRIPT>


What it does for me is, when a certain even happends with the perl, it will print the body tag with an onload=&quot;popup blabla&quot; so that it tells the user that something just happend. If you walk away from your computer, it will keep using the same window. If you minimize it then it re-opens it. I just randomly look for popup windows and I found that this one did it. I learned that it was all due to the win.focus(); to maximize the window every time it is relaunched and it's minimized. The reason it uses the same window is a mystery to me. Just does. The other one I was useing keeped opening new windows. So when i walked away from my computer it would be locked up when I got back, or just have like a 100 po-ups. he he.

I'd also like to kow how to have a link minimize a window. Like the <a href=&quot;javascript:window.close();&quot;>close window</a> does, but I need it to just minimize it. How can I do that?

Thanks For Digging Around For Me. That was nice of you.

the reason is keeps using the same window is the fact that in your statement:

var win = window.open(URL, &quot;popup&quot;,&quot;options&quot;);
you always use the name &quot;popup&quot;. I have a feeling windows keeps track of the window using this second argument in the open method. trying keeping track of a count variable that you can increment every time you call the function and concat it to the end of the name (popup+i).
