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
}
});
