Working example

How to implement

  1. Add class="wb-frmvld" to a div element surrounding the form element 
    <div class="wb-frmvld">
	<form action="#" method="get" id="validation-example">
	...
	</form>
  2. Optional: Wrap each form field name with <span class="field-name">...</span>. This specifies the prefix to use for the error message summary. 
    <label for="fname1">
	<span class="field-name">First Name</span> <strong>(required)</strong>
</label>
  3. Add required="required" to each mandatory form field 
    <input id="fname1" name="fname1" type="text" required="required" />
  4. Optional: For input fields, add one of the configuration options for specialized validation.

Configuration options

hdLvl Heading level for error summary. Add "hdLvl": "headingLevel" to the data-wb-frmvld attribute where headingLevel is the heading level. Use the following JavaScript code instead to configure all instances of the plugin: window[ "wb-frmvld" ] = {"hdLvl": "headingLevel"};.
h2 (default):
Heading level 2
h3:
Heading level 3
h4:
Heading level 4
h5:
Heading level 5
h6:
Heading level 6
ignore Selector identifying the fields to ignore. Add "ignore": "selector" to the data-wb-frmvld attribute where selector is a valid jQuery selector. Use the following JavaScript code instead to configure all instances of the plugin: window[ "wb-frmvld" ] = {"ignore": ".ignore"};.
:hidden (default):
All hidden fields
.ignore:
All fields with the ignore class
Empty string ("")

Events

Document the public events that can be used by implementers or developers.

Event Trigger What it does
wb-init.wb-frmvld Triggered manually (e.g., $( ".wb-frmvld" ).trigger( "wb-init.wb-frmvld" );). Used to manually initialize the form validation. Note: The Form validation plugin will be initialized automatically unless the form elements are added after the page has already loaded.
wb-ready.wb-frmvld (v4.0.5+) Triggered automatically after form validation initializes. Used to identify the element where form validation has initialized (target of the event) 
$( document ).on( "wb-ready.wb-frmvld", ".wb-frmvld", function( event ) {
});
$( ".wb-frmvld" ).on( "wb-ready.wb-frmvld", function( event ) {
});
wb-ready.wb (v4.0.5+) Triggered automatically when WET has finished loading and executing. Used to identify when all WET plugins and polyfills have finished loading and executing. 
$( document ).on( "wb-ready.wb", function( event ) {
});
