Parent() works, and also xPath expressions: (damn, jquery has so much power on traversal)
refer to: http://jquery.com/docs/Base/_expression_/XPath/
Example: $("../",this) should get the parent too.
It actually would really help "Getting Started" if someone would write a bunch (like 100) of common traversal examples. There are a bunch of examples on several different sites, but they lack explanation of what they are doing. (Like the URL above). A traversal cheat sheet! :)
On thing that has REALLY helped me is to use MS Script Editor. You put the word debugger; in your code and then use the watch word functionality to explore the jQuery object. So you can type in anything like $("../",this) and see what that gives you. Easy to play around and see what hits what node.
Hope this helps.

use the .parent() method to do that. Something like this:
$("p").parent()
HTH.
