Quick little article for those hacking AJAX.

One of the powers of JavaScript is it's ability to let you change the property of elements within your webpage on-the-fly (the cornerstone of ajax).

So say you've got an element in your html like;

<span id="elem">some text</span>

Now if i wanted to make it strikethru in JavaScript I'd do...

<script type="text/javascript">
document.getElementById("elem").style.textDecoration="line-through";
</script>

Cool eh, your basically telling the DOM to hunt down any html element with the ID of 'elem' and then change it's CSS text style programatically.

NOTE: style is lowercase, not uppercase!
