Hello and welcome,
I believe that you can not make other instances of objects
constructed like this anyway, so I don't see a problem with being
dependent on the object's name. I use Object Notation to organise my
jQuery code myself, but if I was planning on creating instances of an
object as if it was a class (and therefore need my handlers to be
more generic) then I would use prototype style object-oriented code
instead.
I could be wrong though - I'm no guru - but it's something to consider.
Joel Birch.
