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.

Hello World!

I will be looking for a "special" class as in "dolor_spec" above. I know that I could use hasClass() but the actual class name may not necessarily be known at the time.

I have no idea the structure of your HTML, so you will want to change the CSS selector employed, but if you had something like this:

<div class="mama said knock you out"></div>

then, you could do something like this by basically splitting the class attribute on spaces into an array and then you could play with it from there:

var yourClasses = $("div").attr("class").split(/\s+/);

$.each(yourClasses, function (idx, cls) {

console.log(cls);

});
