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?

A bit late, but using the extend() function lets you call "hasClass()" on any element, e.g.:
var hasClass = $('#divId').hasClass('someClass');

(function($) {
$.extend({
    hasClass: new function(className) {
        var classAttr = $J(this).attr('class');
        if (classAttr != null && classAttr != undefined) {
            var classList = classAttr.split(/\s+/);
            for(var ix = 0, len = classList.length;ix < len;ix++) {
                if (className === classList[ix]) {
                    return true;
                }
            }
        }
        return false;
    }
}); })(jQuery);
