The server still has to do the validity checking. Often pages set up
this way don't work when javascript isn't available. What you save
are round trips when the data is messed up. That may or may not be
better depending on how large the form is wtih and without javascript,
what the rate of mistakes is, what the available bandwidth is and
how loaded the server is.
