Copy class from one element to another

Question

Say for example I have a body with the class "test" and I want to take that class and add it to another div, how can I do this with jQuery?

Thanks

Edit: Something like this?

 $("body.test").clone().attr("class").prependTo("div");

Answer 1

Not sure what you want, but perhaps you mean clone()?

Answer 2

$('element').hasClass("test", function() { $('element2').addClass("test"); } );

should do it - syntactically untested, but it's roughly what I'd do.
