Code:

<html>
<head>
<title>Centered pop-up window</title>

<SCRIPT LANGUAGE="JavaScript" type="text/Javascript">
function popUpCenteredWindow() {
	var iMyWidth;
	var iMyHeight;
	//gets top and left positions based on user's resolution so hint window is centered.
	iMyWidth = (window.screen.width/2) - (122 + 10); //half the screen width minus half the new window width (plus 5 pixel borders).
	iMyHeight = (window.screen.height/2) - (27 + 50); //half the screen height minus half the new window height (plus title and status bars).
	var win2 = window.open("","Window2","status,height=55,width=245,resizable=no,left=" + iMyWidth + ",top=" + iMyHeight + ",screenX=" + iMyWidth + ",screenY=" + iMyHeight + ",scrollbars=no");
	win2.focus();
}
</SCRIPT>
</head>

<body>
<A HREF="javascript:void(0);" onClick="popUpCenteredWindow();">open a new window centered on the screen regardless of user's resolution.
</A>

</body>
</html>

Alright, my question is. I'm new at the pop up windows, and I was wondering just what I needed to do to this thing so that it will open the right page. So do I need to make a new page and just have this code in it or something?

Can someone please explain what all I need to do...
Thanks

You're going to want to put that script on the page you are popping from

Don't forget to add a URL in the href link.

Ok ok, kind of a obvious answer...BUT...I am also wanting to know if there is a script much like this one...that I can change the size of the box. Maybe I should just turn the scrollbar on and hope for the best.

Change the height and width attributes second to last line. But, NOT the iMyHeight and iMyWidth; those variables set the absolute distance from the upper left corner of the screen.

Try this:

Code:

<html>
<head>
  <title>Javascript popup windows</title>
  <script language="javascript">
  <!--

  function openPopUp(WindowURL,WindowName,X,Y){
    T = (window.screen.height/2) - (Y/2);
    L = (window.screen.width/2) - (Y/2);
    newPopUp = window.open(WindowURL,WindowName,'toolbar=no,location=no,directories=no,status=no,resizable=no,copyhistory=no,top='+ T +',left='+ L +',width=' + X +',height=' + Y)
  }

  //-->
  </script>
</head>
<body>

  <a href="#" onClick="openPopUp('http://www.mysite.com','myWindow',300,200)">window 1 size 300x200</a>
  <a href="#" onClick="openPopUp('http://www.mysite.com','myOtherWindow',350,250)">window 2 size 350x250</a>

</body>
</html>

when you call the function openPopUp() you pass it a url name for the new window and the X and Y dimensions of the new window.
