Welcome to the user manual for FormValidation

Latest Updates

From v1.0.0, the library is rewritten in Typescript and ES6 completely. The giant and old jQuery plugin doesn't exist anymore. With the new plugin based architectue, the library has really small core. Everything else is built around as a plugin.

There are some new plugins in this version:

  • Alias: Allow to use multiple instances of the same validator
  • Aria: Add ARIA attributes based on the field validity
  • Sequence: Stop performing remaining validators if there is a validator that the field does not pass

We also bring more supports for popular CSS frameworks. If your form is made with the following frameworks, then use the associated plugin which is built up everything such as showing Icon and Message at desired areas.
