How can I rotate offers with this javascript popunder?

[mpbiz]

I am using the follow javascript popunder code. It works perfectly but I want to make it rotate between 2 different offers.

Here it is:

<!--start popunder-->
<script>
var puShown = false;
var PopWidth = 1370;
var PopHeight = 800;
var PopFocus = 0;
var _Top = null;

function GetWindowHeight() {
var myHeight = 0;
if( typeof( _Top.window.innerHeight ) == 'number' ) {
myHeight = _Top.window.innerHeight;
} else if( _Top.document.documentElement && _Top.document.documentElement.clientHeight ) {
myHeight = _Top.document.documentElement.clientHeight;
} else if( _Top.document.body && _Top.document.body.clientHeight ) {
myHeight = _Top.document.body.clientHeight;
}
return myHeight;
}

function GetWindowWidth() {
var myWidth = 0;
if( typeof( _Top.window.innerWidth ) == 'number' ) {
myWidth = _Top.window.innerWidth;
} else if( _Top.document.documentElement && _Top.document.documentElement.clientWidth ) {
myWidth = _Top.document.documentElement.clientWidth;
} else if( _Top.document.body && _Top.document.body.clientWidth ) {
myWidth = _Top.document.body.clientWidth;
}
return myWidth;
}

function GetWindowTop() {
return (_Top.window.screenTop != undefined) ? _Top.window.screenTop : _Top.window.screenY;
}

function GetWindowLeft() {
return (_Top.window.screenLeft != undefined) ? _Top.window.screenLeft : _Top.window.screenX;
}

function doOpen(url)
{
var popURL = "about:blank"
var popID = "ad_" + Math.floor(89999999*Math.random()+10000000);
var pxLeft = 0;
var pxTop = 0;
pxLeft = (GetWindowLeft() + (GetWindowWidth() / 2) - (PopWidth / 2));
pxTop = (GetWindowTop() + (GetWindowHeight() / 2) - (PopHeight / 2));

if ( puShown == true )
{
return true;
}

var PopWin=_Top.window.open(popURL,popID,'toolbar=0,scrollbars=1,location=1,statusbar=1,menubar=0,resizable=1,top=' + pxTop + ',left=' + pxLeft + ',width=' + PopWidth + ',height=' + PopHeight);

if (PopWin)
{
puShown = true;

if (PopFocus == 0)
{
PopWin.blur();

if (navigator.userAgent.toLowerCase().indexOf("applewebkit") > -1)
{
_Top.window.blur();
_Top.window.focus();
}
}

PopWin.Init = function(e) {

with (e) {

Params = e.Params;
Main = function(){

if (typeof window.mozPaintCount != "undefined") {
var x = window.open("about:blank");
x.close();

}

var popURL = Params.PopURL;

try { opener.window.focus(); }
catch (err) { }

window.location = popURL;
}

Main();
}
};

PopWin.Params = {
PopURL: url
}

PopWin.Init(PopWin);
}

return PopWin;
}

function setCookie(name, value, time)
{
var expires = new Date();

expires.setTime( expires.getTime() + time );

document.cookie = name + '=' + value + '; path=/;' + '; expires=' + expires.toGMTString() ;
}

function getCookie(name) {
var cookies = document.cookie.toString().split('; ');
var cookie, c_name, c_value;

for (var n=0; n<cookies.length; n++) {
cookie = cookies[n].split('=');
c_name = cookie[0];
c_value = cookie[1];

if ( c_name == name ) {
return c_value;
}
}

return null;
}

function initPu()
{

_Top = self;

if (top != self)
{
try
{
if (top.document.location.toString())
_Top = top;
}
catch(err) { }
}

if ( document.attachEvent )
{
document.attachEvent( 'onclick', checkTarget );
}
else if ( document.addEventListener )
{
document.addEventListener( 'click', checkTarget, false );
}
}

function checkTarget(e)
{
if ( !getCookie('popundr') ) {
var e = e || window.event;
var win = doOpen('ENTER-YOUR-OFFER-URL-HERE');

setCookie('popundr', 1, 24*60*60*1000);
}
}

initPu();
</script>
<!--end popunder-->

Anyone have a quick fix for throwing a 2nd URL in there and making it rotate between the 2 50/50?

Thanks for the help.

just create an array of urls for your different offers, then in the doOpen call you bolded, randomly load one of the items in the array. something like

doOpen(offersArray[random_number_function()]);

(I don't know the rand number generator for JS off the top of my head so look that up.)

I appreciate the response but I'll be honest and admit that I have no idea what you're talking about.

Anybody else have a solution a chimp could understand?

Create an array with your URLs for the values:
JavaScript Array Object

Place the array in the paranthesees,and call a random value:
JavaScript Random Value

I'd spell it out but you learn more this way.

+rep to both of you thanks for the help.
