Uni-Form Markup : Validation documentation

Initialize the jQuery plugin

The following code will initialize the jQuery Validation plugin with the default options.

<script type="text/javascript" src=""></script>
<script type="text/javascript" src="../js/uni-form-validation.jquery.js" charset="utf-8"></script>

You may use a global object to hold site wide validation settings. To do this, you should copy the jQuery.fn.uniform.defaults = {} object from the bottom of the validation javascript file into a new file that you use throughout your site. You may then edit options there globally, and will make the Uni-Form library easy to update in the future.

You may also initialize Uni-Form Validation with custom settings by passing a settings object as a parameter when you call uniform().

        prevent_submit : true,
        valid_class    : 'okGo'

Uni-Form Settings

  • prevent_submit (false) Set this to true to prevent the form from submitting if there are outstanding errors in the form
  • prevent_submit_callback (false) Supply a function here and it will be called instead of the internal handler. This function can return true to allow the form to proceed with the commit
  • ask_on_leave (false) Set this to true to have the browser prompt if the visitor has made changes to the form, and then initialized a page unload without submitting the form
  • on_leave_callback (false) Provide a function and it will be called instead of the internal method
  • valid_class ('valid') CSS class name used for div.holder_class elements that have passed validation
  • invalid_class ('invalid') CSS class name used for div.holder_class elements that have failed validation
  • error_class ('error') Please note that both of these are applied by the validation script. You may wish to set them separately at the server perhaps.
  • focused_class ('focused') CSS class name applied to the .holder_class of the current element
  • holder_class ('ctrlHolder') CSS class name that you have used as the control holder class
  • field_selector ('input, textarea, select') List of html elements that will be treated with Uni-Form highlighting and validation (if enabled)
  • default_value_color ("#AFAFAF") HEX color used to display the default data in the background of empty text inputs


  • required
  • validateMinLength
  • validateMin
  • validateMaxLength
  • validateMax
  • validateSameAs
  • validateEmail
  • validateUrl
  • validateNumber
  • validateInteger
  • validateAlpha
  • validateAlphaNum
  • validatePhrase
  • validatePhone
  • validateDate
  • validateCallback

Validators what require a parameter, such as validateMinLength, take that parameter as a class name following the validator in the format of val-{value}.


The validateCallback is a special validator. See the demo/callback.html file for example use. It allows you to define a custom callback to an input without having to add a new validator type to the library.
