JavaScript validation

You mean like replicate the validation rules in JS, and if JS is disabled fall back to server side validation?
That's an interesting idea, but I guess it would require quite some work, and my JS skills are not that sophisticated.
I think special cases like multistep forms might also make the logic more complex.

I'll see if I have time to look into it, but there's no immediate incentive right now.

Awesome :) I trust your JS skills a lot more than my own ;)
You'd like CVS access if that's easier?

How is the status of this? :-D Thank you Rob! ::praises Rob with luxurious gifts::

Marking this one as postponed until further notice.

What is the state of this? Is it the plan to integrate http://bassistance.de/jquery-plugins/jquery-plugin-validation/ somehow? Any progress?

I needed this as well, but not only for webforms but also for regular forms, I started a new project: clientside_validation. For the moment it supports all standard webform components and some regular FAPI elements.

I just added support for the following rules to my module (clientside_validation):
- Numeric values
- Minimum length
- Maximum length
- Equal values
- Unique values
- Specific value(s)
- Minimum number of selections required
- Maximum number of selections allowed
- Exact number of selections required

I did some basic testing, but all feedback appreciated.

Feedback on this could probably be put in its proper issue queue.
I have added a mention of your module on the webform_validation project page earlier, so people looking for that would be directed that way...

More accurate status :)
