selecting the first of multiple classes

Question

Not sure if you can do this, but I want to select the first of two classes of an element with jQuery and return it's first class only.

<div class="module blue">

I want to return 'module'.

tried this:

var state = $('body').attr('class').first();

but none of that seems to work, thanks for any advice.

Answer 1

Try

var class = $('.module').attr('class');
var st = class.split(' ');
var firstClass = st[0];
