forms validation plugin that supports AJAX requests, automatic decoration of fields, localized error messages. Integrable with Angular, Backbone, Knockout.

Example form (data is not submitted anywhere!)


  1. External libraries in this demo are loaded using CDN; if the connection is not stable this demo could stop working.
  2. The Year field accepts only the input of integers (this is a constraint automatically set by the DataEntry, for the "integer" validation).
  3. Copy-paste is always allowed, and an error is displayed when pasting a text into the Year field.
  4. The first invalid field is automatically focused upon validation.
