I suppose this is more suited to when your models and schema are also defined on the client side?
Having just hit this situation (validating a form client-side), I found the best solution was to transport the form schema from the server (because I use Django, I can easily whip up a ModelForm), then push that into a simple Javascript Form object which renders the schema and adds validation. Maybe there's better ways, but that's what worked for me. Curious what others have done .. :-)
- jva 14y agoWith Rails I did come up with a similar solution to Parley.js. Just add a helper that renders the needed data-attributes and you're done. Your solution sounds nice for single page apps.
- pestaa 14y agoNice to have a full-blown client-side equivalent of schema definitions and validation rules, but for most of my forms, I just add it quickly and dirty. Sometimes it feels bad, but most web toolkits treat JavaScript as a second-class citizen and not an integrated part of its core (and no, throwing in a jQuery does not count). Yii framework (PHP) supports validation through Ajax (serializes the form, sends for regular server-side validation and displays the errors on the form). A godsend if your form does not change, and impossible to work with if it is dynamic (consider batch entries with "Add line" features, etc.). I haven't seen a seamless integration on this higher level.
- phpnode 14y agoYii can also do client side validation (without an ajax call) for most of its built in validation rules.
- insin 14y agoIs the form definition-to-JavaScript code open source, by any chance? I ported django.forms to JavaScript so I could use it with Node.js, but it also runs on the client: https://github.com/insin/newforms https://github.com/insin/newforms Could be useful to plug the two together.
