I can see how and Ajax approach dependent upon CF validation for error messages to the user could be slow.
However, up until now, the only validation I've ever used is server-side with CF. I'm working on a method of combining JS for message display, bypassing the need to refresh a form page as I have been doing, but still using CF for validation. I haven't implemented it on a site, yet, but it seems very responsive in testing. I'm currently validating each field on blur, which, as Josh mentioned, provides the user with instant feedback on each field instead of forcing the user to submit a form to deal with errors. Also, with this technique, I can do what you mentioned, which is validate against query data for various purposes, such as checking a user-proposed username (again as Josh mentioned) or validating addresses for users, etc. Some of the query-based validation could take longer, sometimes much longer, but someone on the jQuery list worked out a way to place "spinner" beside a field while the entry is being validated. I've had jQuery and CF dancing around each other for the last month trying to figure out the best approach. Looks like I'm close. Thanks for your insight! And everyone else's, too!

I'm not sure it's a good approach. Ajax has its price: the time needed for a request on your server; May be not as long as reloading the page, but not far. The advantage of Javascript validation is that it is instantaneous. IMO, Ajax should preferably be used for dynamic forms, like big selects depending on other selects, etc. -- _______________________________________ REUSE CODE!
