This script makes it simple to create multiple validation rules for a single field.

The API

To use the script, add the data-validation-rules attribute to the field and set the a reference to the rules container as the value:

<input type="text" name="username" required="required"
data-validation-rules="username-rules"
	>

Then include a list of rules in your markup within a container with that ID. Rules are indicated by a data-validation-rules-rule attribute with a regular expression string value:

<ul id="username-rules">
	<li data-validation-rules-rule="[A-Z]+">At least one capital letter</li>
	<li data-validation-rules-rule="[a-z]+">At least one lowercase letter</li>
	<li data-validation-rules-rule="[\d]+">At least one number</li>
</ul>

Then call the plugin on a field container (like the form or the body):

$('form').easyValidationRules();

You can configure the classes this plugin uses by passing them to the plugin as part of a configuration object:

$('form').easyValidationRules({
	field_invalid_class: 'my-custom-invalid',
field_valid_class: 'my-custom-valid'
});

Configuration options are as follows:

• trigger_event - The event to trigger validation on. Default: "keydown"
• each_delay - Delay between each rule being classified. Default: 150
• field_invalid_class - The class to apply when the field is invalid. Default: "validation-invalid"
• field_valid_class - The class to apply when the field is valid. Default: "validation-valid"
• rule_unmatched_class - The class to apply when the rule’s requirement are not met. Default: "validation-unmatched"
• rule_matched_class - The class to apply when the rule’s requirement are met. Default: "validation-matched"
