But isn't this scenario assuming that JS is available? I thought the argument was that one has to assume that JS isn't available and a complete server-side validation routine would have to be in place. It seems that most on the list have been saying use the client-side JS for user experience enhancement, but assume JS is not available. In that case, I'd need to run server-side validation on everything anyway... ??? -----Original Message----- From: Dave Watts [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 17, 2007 1:25 AM To: CF-Talk Subject: RE: Client-side validation or Server-side Validation? > Client-side validation is going to have to server-side > validation, too, which means the server is going to have to > handle all the validation that the client-side does.

This will execute comparatively quickly, and will let you build a user-friendly and responsive interface. You'll still need to do the same checks when the data is actually submitted to the server, but these shouldn't require any significant processing time if they were previously run on the client, because they'll all pass. And if they don't, for whatever reason, you won't really care about the processing overhead at that point anyway.
