jQuery - if two classes - get the first one

Example:

Here we have <p class="tab1 current"></p>

How can I get only the first class?

var GetFirstClass = $('p').attr('class').filter(':first'); ??

Any help开发者_开发问答 much appreciated.

Use JavaScript's split function:

$('p').attr('class').split(' ')[0]

Demo

$('p').attr('class').split(' ')[0]

You can split the string based on the space.

$('<div class="a b"/>').attr('class').split(' ')[0]
