Client side form validation
Thursday, February 8th, 2007Form validation is vital to every web based application, and too often I’ve seen it implemented page-by-page. Custom code blocks to check for email address formats, telephone numbers, social security numbers, etc.
If you need client-side form validation and you can rely on javascript, I highly recommend Andrew Tetlaw’s “ Really easy field validation.” It does require prototype.js and of course, java script enabled browsing.
I’ve written a few additional validators that I’ll post sometime soon for anyone that might be interested.
