The only problem i have with JS validation is that it is going to produce redundant code. You see that JS validation is no substitute for server-side validation, as tools such as LWP and crew make it very easy to bypass your front-end "security". As long as you don't mind maintaining both the JS and server validation, then god-speed to you, but i still think that JS validation is waste of my time and my client's money. ;)

UPDATE:
I can admit that what sauoq says is good - if you do have some expensive submission that will benefit from being validated on the client side first, well ... go for it. Some redundancy isn't so bad, especially when you compare the chore of keeping it consistant to ... washing dishes. :D It just ain't so bad after all. ;)
