Background changing depending on title.

[the grim axel]

I'm trying to write a code that will use css to change the background of a page dependent on the page title. The image used for the background has the same title as the page. I was trying to use the document.write code to write a css tag that sayed

<style>#content{background-image:url(images/{imagenamehere}.jpg);</style>

Can anyone help me with this?

The javascript I have so far is as follows.

function background(){
var name = document.title;
var code = "<style>#content{background-image:url(/images/" + name + ".jpg);background-repeat:repeat-y;background-position:right;background-attachment:fixed;</style>";
document.write(code);}

This is inside a script tag in the header and I call the background() function onLoad. Can someone tell me what I'm doing wrong?

Why don't you use a css style element in the page for this?

You can't use document.write after the page has loaded, because the document is closed for writing.

mrhoo's suggestion is the correct way of solving this, e.g.

var code = "<style>#content{background-image:url(/images/" + name + ".jpg);background-repeat:repeat-y;background-position:right;background-attachment:fixed;</style>";

becomes [code=javascript]var content = document.getEle mentById("conte nt");
content.style.b ackgroundImage = "url(/images/" + name + ".jpg);";
content.style.b ackgroundRepeat = "repeat-y";
// background-position = style.backgroun dPosition, background-attachment = style.backgroun dAttachment[/code]

Thank. I didn't know you could access the CSS styles from javascript.
