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

Why has no one simply listed.

$(element).attr("class").split(/\s+/);

EDIT: Split on /\s+/ instead of ' ' to fix @MarkAmery's objection. (Thanks @YashaOlatoto.)
