Description

I have developed an extension for Commons Validator that renders the dynamic
javascript for Form validation.

More details on the listed web site along with a download of the source code
and a sample webapp that lets you try it out and shows you the source code.

• The main component is the ScriptRenderer class which renders the necessary
  javascript for form validation to a StringBuffer.

• Static javascript methods have more appropriate method signatures and are
  smaller and simpler.

• fields are validated in the order defined in validation.xml (rather than by
  Validator)

• it handles 'indexed' field validation

• I've re-written the Date Validation Javascript Validator so its simpler and
  takes properly into account the difference between the different date patterns.

• It can now provide "field level" validation - for example in the onchange
  method of a field.

There are examples of all this in the sample webapp. The only word of warning -
until a couple of weeks ago I knew virtually no javascript! So it would be good
if someone experienced could re-view it - the sample webapp shows you the
generated javascript.

I would like to add this to Commons Validator, but thought I would post it fore
re-view first.
