validate.js is a lightweight JavaScript form validation library inspired by CodeIgniter.
- Validate form fields from over a dozen rules
- No dependencies
- Customizable Messages
- Supply your own validation callbacks for custom rules
- Chainable customization methods for ease of declaration
- Works in all major browsers, (even IE6!)
- Modeled off the CodeIgniter form validation API
var validator = new FormValidator('example_form', [{ name: 'req', display: 'required', rules: 'required' }, { name: 'alphanumeric', rules: 'alpha_numeric' }, { name: 'password', rules: 'required' }, { name: 'password_confirm', display: 'password confirmation', rules: 'required|matches[password]' }, { name: 'email', rules: 'valid_email' }, { name: 'minlength', display: 'min length', rules: 'min_length[8]' }], function(errors) { if (errors.length > 0) { // Show the errors } });
