We have a lot of forms on our site that are using a script called fValidate for client side validation. However, fValidate is not very friendly to use, hasn't been updated in years, causes incompatibilities with jQuery in IE6 and is just generally horrible. We're looking to replace it with another validator, one that plays nice with jQuery is a must, one that works as a jQuery plugin would probably suit our needs better as we are planning on using jQuery effects on the forms too.
Research has dug up a number of jQuery validation plugins but the two major ones seem to be Validate and YAV. The former seems to be jQuery native, whereas the latter is apparently a plugin based on a third party library. Both seem to offer a lot of power. Before we commit to either one or the other, has anybody got any experience of both of these plugins? Can you offer an opinion on which one is the better choice?
