[jQuery] typo in docs for "post" entry

[humanclock]

Hey, I couldn't tell if this should get posted here or in Trac, so I'm
posting it here.

I wanted to point out a bug in the docs:
http://docs.jquery.com/Post

       function(returned_data)
         {
         alert(data);
         });

should be:

       function(returned_data)
         {
         alert(returned_data);
         });
