How do you get an element with a certain class within $(this) in jQuery?
<p>I'm working on a function that process form data through ajax. I've got the function written, but in the end, once I've got the data, I need to put a message into a div within the submitted form. The div has a class of 'message'.</p>

<p>When referring to the form as <code>$(this)</code> in my function, how would I get to the div with the class of "message" within it?  (So the equivalent of <code>$('form.message')</code>, but using <code>$(this)</code> instead of form)</p>
