I've been trying to create a script to change the background image of my site and store it in a cookie. This is what I have so far:


<script language="javascript">
<!--
var backImage = new Array();

back[0] = "aquablack.jpg";
back[1] = "aquablue.jpg";
back[2] = "aquared.jpg";

function changebgimage(backnum){
if (document.body){
document.body.background = back[backnum];
}
}
function cookie(number){
if (document.body){
document.cookie = "background="+number+";expires=Fri, 17 Dec 2010 12:00:00 GMT";
}
}

function bgimage(somenumber){
if (document.body){
changebgimage(somenumber);
cookie(somenumber);
}
}

function ReadCookie(cookieName) {
var theCookie=""+document.cookie;
var ind=theCookie.indexOf(cookieName);
if (ind==-1 || cookieName=="") return "";
var ind1=theCookie.indexOf(';',ind);
if (ind1==-1) ind1=theCookie.length;
return unescape(theCookie.substring(ind+cookieName.length+1,ind1));
}

var bg = ReadCookie(background);

function initialbackground() {
if (document.body){
changebgimage(bg);
}
}
//-->
</script>

Right after the <body> tag, I have this:


<script language="javascript">
initialbackground();
</script>

I copied the ReadCookie function, so I have no idea how it works. The bgimage function changes the background and sets the cookie, but the initialbackground function doesn't seem to work. What's wrong with the script?

What does it do/not do?
A link to your page would help.

Nevermind, I figured it out.

I needed to put quotes.

var bg = ReadCookie("background");
