Question

jQuery - get the first class only from a element

Answer 1

A:

var first = jQuery.attr('class').split(" ")[0];

Note that `jQuery.attr('class')` is wrong, there should be a selector too.

You're soo smart... I've just preserved the form of the question. If he doesn't know how to use jQuery than it's useless for him to get the first class of an element lol :)

and he said "`jQuery.attr('class')` will return both classes", which indicates that by `jQuery` he meant an instance of the jQuery object, not the contructor function which invokes `jQuery.fn.init`

Answer 2

+1 A:

You need to split that into an array:

alert(jQuery('selector').attr('class').split(' ')[0]);

Or use a regex: `var first = $('#foo').attr('class').replace(/^(\S*).*/, '$1');`
