Changing DIV background with JavaScript?

[realistic]

I know there is a way to change a DIV HTMT text using JavaScript, but is there any way to change the DIV background image? Or background color?

// change bg image

document.getElementById("div1").style.backgroundImage = "url(someImage.jpg)";

// change bg color

document.getElementById("div2").style.background = '#000000';

my answer is,

<script type="text/javascript" language="javascript">
02 //get the page URL and take the substring after the ?
03 qsFull = window.location.search.substring(1);
04 //split the substring based on the location of the =
05 qsValue = qsFull.split("=");
06 //check on the value of querystring parameter and write the appropriate headline
07 if(qsValue[1] == "no")
08 {
09 document.writeln('<h1>Div1<\/h1>');
10 document.getElementById('div1').style.backgroundCo lor = '#D4DBE7';
11 }
12 else
13 {
14 document.writeln('<h1>Div2<\/h1>');
15 document.getElementById('div2').style.backgroundCo lor = '#D4DBE7';
16 }
17 </script>
