Hi,

I am more interested to know about 'Wicket jQuery Validator integration' .
Could you please post some more information with example. That would be
really great!

Thanks in advance! :)

RE: Wicket jQuery Validator integration

2012-02-29 Thread Evan Sable
Hi Zac, this sounds great - I would be very appreciative if you make this
code public, and I imagine it would be useful for many.  I was just about to
take a look at the wicketstuff-client-and-server-validation project which
seems to be a similar idea, but it would be great to check out what you have
done using wiquery.  Have you had a chance to post this somewhere?
Thanks,
-Evan

Subject: Wicket jQuery Validator integration

Good morning,

Reading a recent thread about accessing jQuery Validation from Wicket
reminded me that I've developed some code that might be of use.  I'm not
sure if this is something anyone else would be interested in or if it's
something that might eventually be integrated into Wicket core or if it
would be more appropriate for one of the existing jQuery/Wicket integration
libraries.  I wanted to describe what I've cooked up so far.  If this is
anything that would be useful, I'd be willing to clean the code up a bit to
extract a few bits that are specific to our environment and post the code
somewhere.

My intent was to get client-side validation using Wicket's existing
validation classes without requiring AJAX calls to make them work and
preferably without requiring Page's to include lots of unsightly JavaScript.
Also, not duplicating validation logic on the client  server tiers was
desirable.  The code was originally developed for a site that was expected
to receive a high amount of traffic in a short period of time, and avoiding
unnecessary server calls was a priority.  

I created a subclass of Form (ClientSideValidatingForm) which examines each
FormComponent (and sub-Form) added to it and extracts information about the
standard Wicket validations.  It generates JavaScript which uses jQuery's
Validator library to apply client-side checks equivalent to the Wicket
server side checks.  The nice thing about this is that you get client-side
validation for free just by adding the normal Wicket validations plus you
still get all your validations backed up in the server side in case
JavaScript is unavailable or disabled.

The implementation of the class does lack a bit in terms of elegance
unfortunately.  As the Wicket validation interface doesn't currently know
anything about JavaScript, it was necessary to run a chain of instanceof
checks against all the known Wicket validations and emit JavaScript to
mirror their logic.  I also created an extension of the Wicket IValidator
interface which can provide JavaScript functions to perform validation
equivalent to the server-side Java code.  The extraction code in
ClientSideValidatingForm preferentially checks for this interface and uses
provided JavaScript if available.  Otherwise, it's a bunch of instanceof's
to check for known validations or log an error if an unknown instance of
IValidator is found.

Long term, it would be helpful if the stock Wicket IValidator interface
could include a method to get JavaScript validations for all of the stock
validations.

The code is pretty tightly bound to jQuery Validator at this point, but it's
likely the methodology could be abstracted to other validation frameworks.
It's also built using WiQuery, though that's mostly as a convenience to get
the same version of jQuery that we use elsewhere.  The same could easily be
implemented without WiQuery provided a version of jQuery was contributed to
the response via some other mechanism.

Is this something anyone would be interested in?  

Best regards,
Zac Bedell

Zachary, I will definitely find your code that does client-side
validation useful. I don't know if this helps but Jeremy Thomerson had
a presentation on custom JavaScript integration with Wicket
(http://stuq.nl/weblog/2009-11-27/london-wicket-meetup-wicket-1-5-wiquery-brix-and-more).
