You've tried using several different validation libraries. Many were pretty good, full-featured, and easy to use; but somehow you're always running into cases where you need some weird specific validation rule, and hacking these plugins is often really complex and against the grain.

Revalidate is a validation Framework. It has been designed to make writing strange validation rules easy while still having great UI.

Example Usage:

Set up validation on a form:


Create and attache a validation rule:

  validator: function() {
    return $.trim(this.value);
  revalidateOn: 'blur keyup',
  message: 'This field is Required'

Specifying errors on load

Add a data-error attribute to field to make a field have an error on initial load.


This is a new library so please report any bugs you find.


  • Set up QUnit for all the settings
