Looking for a simple JavaScript example that updates DOM

Question

I am looking for a simple JavaScript example that updates DOM.
Any suggestions?

Answer 1

Here is a short pure-javascript example. Assume you have a div with the id "maincontent".

var newnode = document.createTextNode('Here is some text.');
document.getElementById('maincontent').appendChild(newnode);

Of course, things are a lot easier (especially when you want to do more complicated things) with jQuery.
