You still need to do the form validation at the server. If the user has disabled javascript then your solution will not work. Also, unless you have written your form processing correctly there is nothing to stop a user saving your form to their local computer and editing it - even re-writing your javascript if they need to.

However, well written javascript will enable a user to get immediate feedback on the form data without submitting it. Just don't rely on it.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
