Including it on your page

Include jQuery and the plugin on a page. Then select a form to validate and call the validate method.

<form>
	<input required>
</form>
<script src="jquery.js"></script>
<script src="jquery.validate.js"></script>
<script>
$("form").validate();
</script>

Alternatively include jQuery and the plugin via requirejs in your module.

define(["jquery", "jquery.validate"], function( $ ) {
	$("form").validate();
});

For more information on how to setup a rules and customizations, check the documentation.

Reporting an Issue

IMPORTANT NOTE ABOUT EMAIL VALIDATION. As of version 1.12.0 this plugin is using the same regular expression that the HTML5 specification suggests for browsers to use. We will follow their lead and use the same check. If you think the specification is wrong, please report the issue to them.

1. Make sure the problem you're addressing is reproducible.
2. Use http://jsbin.com or http://jsfiddle.net to provide a test page.
3. Indicate what browsers the issue can be reproduced in. Note: IE Compatibilty modes issues will not be addressed.
4. What version of the plug-in is the issue reproducible in. Is it reproducible after updating to the latest version.

Documentation issues are also tracked at the jQuery Validation issue tracker. Pull Requests to improve the docs are welcome at the jQuery Validation docs repository, though.
