[jQuery] Re: My first jQuery plugin

[ProggerPete]

Hi Andy,
  parents doesn't do quite what I want.  I want a method I can use in
event delegation handlers that basically says, 'Give me the nearest x
element'.  I could of course check the current element, if it doesn't
match I could then do a parents and then work on the 1st result in
that, but that would be a bunch of extra processing for no gain (while
it continues to check parents that I have no interest in).

  I was more after info about any silly things I've done while
implementing the function.  I've since discovered pushStack which
helps a fair bit.  =)

Cheers,
Pete
