Has anyone done any clientside validation with FormFu? Basicly I want
to only specify constraints etc once, in the FormFu-config, and then
just have it magicaly work on the forms in the web app, or atleast
provide me with the information needed to do the client side stuff
(like what constraints are on a field etc).
If that is not possible, is it possible to process only "part" of a
form? So I can call back to the server to check each field as they
are
filled out?
If anyone has any thoughts on any of this, I would be glad to hear it
I put this JS demo together about a year ago.
http://www.fireartist.com/tmp/client-side-constraint.html
It supports filters & constraints and uses the same error markup that
server-side validation would generate.
At the moment, it uses an old version of dojo.
It would probably be best to have the more advanced functionality
(such as class name changes) isolated in core functions, and allow
them to be implemented in different frameworks - and have the
individual constraints, filters, etc only use standard JS.
Although, if someone's willing to write the necessary functions in
cross-browser JS so that we don't need an external library, that would
be great.
I created the branch /branches/auto-js for this, but have never
checked the changes in, so I'll probably need to start from scratch as
the internals have changed so much since the branch was made.
I imagine it being implemented such that you can switch it on with
something like:
clientside_validation: 1
clientside_library: 'Dojo'
That sounds ideal. I would whip up a MochiKit implementation asap :p
However, is it possible to easily manipulate what is outputed, so as
to add information about constraints etc to the markup?
