Its a good idea only till the issue of your programming comming to the user doesnt come into play.
you can do tokenizing or parsing and things like that not to the place of getting recordsets to the browser.

What IPR (intellectual property rights) issues might be associated with use of JavaScript?
Javascript can be copied easily. even if you use microsoft's encoder

Under what circumstances might browser compatibility issues not be a problem for a JavaScript developer?
as long as you stick to IE or the latest version of netscape. both are fairly interchangable. if you try DHTML stunts then stay with ie

use javascript for validations thats what it started with. but this doesnt give you an escuse to miss out server side validations. there are chances persons wont use your javascript to upload data.

Its a good idea only till the issue of your programming comming to the user doesnt come into play: you expose your programming to the client he can view your source:
parsing takes time and cpu so you can offload such things to the client side.

last answer : use javascript for validation not for DHTML
