I'm trying to figure out how to use web.py and JQuery together and I
found a neat example posted by jgfoot last year on how to do this. But
I can't seem to get it to work the way I think it should. My
understanding is that the
#riverName paragraph should get filled with the river corresponding to
the city. But this doesn't happen for me. But I do know that it is
retrieving the river name as it prints to stderr. Can anyone shed any
light on why this isn't behaving as I think it should or if there are
better ways on combining web.py and JQuery (or any Ajax-y type thing)
Cheers
Ben
