Frank: I agree, you need to validate on the server as well. But that doesn’t mean you can’t catch errors as early as possible to aid the user.

Rob: I’d be happy to help out. Pop me an email on christian at cjohansen.no and I’ll check out your problem. I’m using Validatious successfully on several sites.

Simplenews: Well, the screenshot is just one example of how you can deploy Validatious. Validatious is really a JS validation engine – it does not ship any ready-to-use design. It’s designed to be highly flexible, and you can configure everything such as when to do validation. Additionally, you can write your own error formatting code for highly customized applications. Do give it a shot!

Nice, but as any JS validation not secure enough. Form validation must be done server-side.

Thanks for sharing,

We were looking for just such a thing. But I think they didn’t work enough on a few things. For example the messages pop up immediately even if you didn’t enter anything. Inline-validation is a very complicated thing as this great article shows:
http://www.alistapart.com/articles/inline-validation-in-web-forms/

I don’t even know if it’s an advantage for a normal registration form with a maximum of 4 fields like ours. So we decided to leave it out.

Some designs like signup on twitter are incredible of course. For example they don’t display “can’t be left empty” but “please enter” in grey when a field is focused. That’s a great solution and it’s my suggestion for validitious.

Another thing is, that it’s not clear what the checkmark means. For that see the article I mentioned. BTW: Twitter got that right too.

It’s an awesome library, very thorough code as well. Def check it out. FYI: I made a Rails plugin that maps ActiveRecord model validations to Validatious 2.0:
