Baggrundsfarve i DHTML

Så'n cirka:

<html>
<head>
<title>BG skift</title>
<style>
BODY{background-color:white}
</style>

<script>function skift(farve){
if(document.all)eval('document.body.style.backgroundColor ="'+farve+'"')
if(document.layers)eval('document.bgColor="'+farve+'"')
}
</script>
</head>
<body>
<a href="#" onclick="skift('yellow')">Skift til gul</a>

</body>
</html>

Jeg mener bare at sætte en baggrundsfarve på en lille del af siden. En <div> tag.

Samme princip ... og næsten identisk kode - denne er stjålet fra www.bratta.com, det var ham, der inspirerede mig til at begynde på DHTML:

<html>
<head>
    <title>Cross-browser DHTML - BgChange Script</title>
<style>
BODY{background-color:white}
DIV{font-family:arial,helvetica; font-size:10pt}
</style>
<script>

function changeBc(div,color){
    if(document.all)eval('document.all.'+div+'.style.backgroundColor="'+color+'"')
    if(document.layers)eval('document.layers.'+div+'.bgColor="'+color+'"')
}
</script>
</head>
<body>
<div id="div1" style="position:absolute; width:300; top:120; left:200"><a href="#" onclick="changeBc('div1','red')">change me to red background</a> - <a href="#" onclick="changeBc('div1','white')">changeback</a></div>

<div id="div2" style="position:absolute; width:300; ; top:150; left:200; height:100; clip:rect(0,300,100,0)"><a href="#" onclick="changeBc('div2','silver')">Skift til grå</a> (this one has a clip to show how it can cover a spesified area in both browsers, look in the style tag)</div>
</body>
</html>
