Get class list for element with jQuery

Question

Is there a way in jQuery to loop through or assign to an array all of the classes that are assigned to an element?

ex.

Answer 1

On supporting browsers, you can use DOM elements' classList property.

$(element)[0].classList

It is an array-like object listing all of the classes the element has.

If you need to support old browser versions that don't support the classList property, the linked MDN page also includes a shim for it - although even the shim won't work on Internet Explorer versions below IE 8.
