[jQuery] Re: In this code, what would $(this) in the success part refer to?

[Miloš Rašić]

Since you're already discussing $(this), I'd like to ask something.
It is a good practice to assign selected nodes to variables if you are going
to need them more than once so as not to make jQuery search the document for
them again and again. What about $(this)? Do I need to assign it to a
variable or is it fast enough for repeated use?
