JavaScript getting an elements class without any libraries

Question

I would like to get the value of the class attribute for an element using JavaScript. However in this particular situation I don't have the luxury of library such as YUI, jQuery, etc. and need to stick to the basics.

Specifically, I am looping over a table and want to check the class of the cell.

I tried:

var colClass = el.getAttribute('class');

and

var colClass = el.class;

But neither seems to be working. In the above example, el is set from cells array of a table, such as var el = document.getElementById('myTable').rows[y].cells[y];

Answer 1

Maybe you should try this

var colClass = el.className
