What is the preferred method of retrieving class names with jQuery?

Question

So far, I'm using

$(this).attr('class');

But I worry about compatibility because I know some browsers do some weird things with class and id attributes. Seems like a great place for jQuery to implement its own method, but I can't find it in the documentation.

Isn't there a bug somewhere that has className and id acting on the same objects? This may only apply to IE setting values, or maybe I'm just misremembering.

As meder pointed out, I was thinking of id and name, not id and class.

Answer 1

.attr('class') would work out because internally it uses className
