Need to display multiple popups

I’ve been using the following popup script for several years:

<a href=“javascript:;” onClick=“MM_openBrWindow(‘MySite/Aids/Popups/World.php?MySS=<?php echo $MySiteID.$PopParent; ?>’,‘IRSA’,‘scrollbars=yes,resizable=yes,width=175,height=250’)”>PopUp</a>

I just upgraded to a new script that’s less complicated and is supposed to be more user-friendly for people who have JavaScript disabled:

<a href=“MySite/Aids/Popups/World.php?MySS=<?php echo $MySiteID.$PopParent; ?>” rel=“popup standard 150 400 noicon”>PopUp</a>

It works fine except for one problem: I can only open one popup at a time. Does anyone know how I can modify the associated JavaScript file (posted below) so I can open multiple windows?

Or if you know of another script that would accomplish what I need, that would be fine, too. There must be a thousand examples on Google, but I can’t seem to connect with anything that works for me. Thanks.

On Edit: I should add that all my popup links target the same file. The file simply displays different information depending on PHP values passed via the links.

var newWindow = null;

function closeWin(){
	if (newWindow != null){

function popUpWin(url, type, strWidth, strHeight){
	type = type.toLowerCase();
	if (type == "fullscreen"){
		strWidth = screen.availWidth;
		strHeight = screen.availHeight;
	var tools="";
	if (type == "standard") tools = "resizable,toolbar=no,location=no,scrollbars=yes,menubar=no,width="+strWidth+",height="+strHeight+",top=0,left=0";
	if (type == "life") tools = "resizable,toolbar=yes,location=yes,scrollbars=yes,menubar=yes,width="+strWidth+",height="+strHeight+",top=0,left=0";
	if (type == "console" || type == "fullscreen") tools = "resizable,toolbar=no,location=no,scrollbars=no,width="+strWidth+",height="+strHeight+",left=0,top=0";
	newWindow =, 'newWin', tools);

function doPopUp(e)
//set defaults - if nothing in rel attrib, these will be used
var t = "standard";
var w = "780";
var h = "580";
//look for parameters
attribs = this.rel.split(" ");
if (attribs[1]!=null) {t = attribs[1];}
if (attribs[2]!=null) {w = attribs[2];}
if (attribs[3]!=null) {h = attribs[3];}
//call the popup script
//cancel the default link action if pop-up activated
if (window.event) 
	window.event.returnValue = false;
	window.event.cancelBubble = true;
else if (e) 

function findPopUps()
var popups = document.getElementsByTagName("a");
for (i=0;i<popups.length;i++)
	if (popups[i].rel.indexOf("popup")!=-1)
		// attach popup behaviour
		popups[i].onclick = doPopUp;
		// add popup indicator
		if (popups[i].rel.indexOf("noicon")==-1)
			popups[i].style.backgroundImage = "url(pop-up.gif)";
			popups[i].style.backgroundPosition = "0 center";
			popups[i].style.backgroundRepeat = "no-repeat";
			popups[i].style.paddingLeft = "15px";
		// add info to title attribute to alert fact that it's a pop-up window
		popups[i].title = popups[i].title + " [Opens in pop-up window]";

addEvent(window, 'load', findPopUps, false);

Update: I just discovered that I could open multiple popups with my original script because every link had a unique ID (e.g. IRSA in the example above). So I guess my idea of just linking to one popup file with dynamic content isn’t going to work.

Instead, I need to figure out how to modify the new JS code that a new window pops up every time a link with a unique ID is clicked. Does anyone know how to do that? And how would I add the ID to the link?
