How do you (if you) manage client side validation with grails ? Do you use a plugin or do you mirror your constraints using a javascript framework ? Cheers

回答1:

I haven't used them personally but these two plugins might help you out:

http://grails.org/plugin/javascript-validator

http://www.grails.org/plugin/remote-constraints

On Grails projects that I've been a part of, We haven't used a plugin but rather a mashup of javascript plugins and custom validators (jQuery plugins, Prototype, Dojo, etc.) to achieve the client side validation. Its handy to provide instant field-level validation on the client.

As leebutts said, The source of these plugins are open. Why not consider enhancing one(or both) of these plugins to achieve what you need and contribute that back to the community?

Might be worth checking out the new constraints plugin. With it Constraints become a Grails artefact, and might make this job easier.
