Validator, for Bootstrap 3

The Validator plugin offers automatic form validation configurable via mostly HTML5 standard attributes. It also provides an unobtrusive user experience, because nobody likes a naggy form.


  • Configurable via data-api and standard HTML5 attributes
  • Patient to inform user of errors and eager to let them know the errors have been resolved
  • Submit is disabled until the form is valid and all required fields are complete
  • Customizable error messages
  • Custom validator functions
  • Validation of an input field via AJAX
