<script type="text/javascript">
function getvalue(list)
{
while(list.options.length) list.options[list.selectedIndex].value=null;
var value = list.options[list.selectedIndex].value;
document.write(value);
document.bgColor = value;
}
</script>
</head>
<body bgColor="lavender">
Here is the list for you to Change the bgColor!

<select name="list1" onchange="getvalue(this)">
<option value="green">Green</option>
<option value="orange">Orange</option>
<option value="yellow">Yellow</option>
<option value="pink">Pink</option>
</select>
</body>
