A simple jQuery plugin to validate forms.

Project README

Coming soon: A minimalist validation library for client side and server side..

jQuery Validate

License: MIT.

Version: 1.1.2.

Requires: jQuery 1.7+.

To use jQuery Validate you just need to include in your code a version of the jQuery library equal or more recent than 1.7 and a file with the plugin. Click here to download the plugin.

After this, you just need select your form and calling the jQuery.fn.validate method.

See a example:

jQuery('form').validate();

After calling the jQuery.fn.validate method, you can validate your fields using data attributes, that are valid to the HTML5, according to the W3C.

See a example to required field:

<form>
	<input type="text" data-required />
</form>

jQuery Validate supports all fields of the HTML5 and uses WAI-ARIA for accessibility. You can use several attributes to your validations.

Attributes

	<th>Description</th>

	<th width="75px">Default</th>
</tr>

<tr>
	<td>data-conditional</td>

	<td>Accepts one or more indexes separated by spaces from the `conditional` object that should contain a the boolean return function.</td>

	<td></td>
</tr>

<tr>
	<td>data-ignore-case</td>

	<td>Accepts a boolean value to specify if field is case-insensitive.</td>

	<td>true</td>
</tr>

<tr>
	<td>data-mask</td>

	<td>Accepts a mask to change the field value to the specified format. The mask should use the character groups of the regular expression passed to the <a href="#data-pattern">`data-pattern`</a> attribute.</td>

	<td>${0}</td>
</tr>

<tr>
	<td>data-pattern</td>

	<td>Accepts a regular expression to test the field value.</td>

Callback

Removing validation

You can remove validation of a form using the jQuery.fn.validateDestroy method.

Example:

jQuery('form').validateDestroy();

Changing the default values of jQuery.fn.validate

You can changes the default values of jQuery.fn.validate using jQuery.validateSetup method.

Example:

jQuery('form').validateSetup({
	sendForm : false,
	onKeyup : true
});

Creating descriptions

You can create descriptions to the field states.

Example:

<form>
	<input type="text" data-describedby="messages" data-description="test" />

	<span id="messages"></span>
</form>
$('form').validate({
	description : {
		test : {
			required : '<div class="error">Required</div>',
			pattern : '<div class="error">Pattern</div>',
			conditional : '<div class="error">Conditional</div>',
			valid : '<div class="success">Valid</div>'
		}
	}
});

Creating extensions

You can use the jQuery.validateExtend method to extend the validations and calling the extensions with data-validate attribute.

Example:

<form>
	<input type="text" name="age" data-validate="age" />
</form>
jQuery('form').validate();

jQuery.validateExtend({
	age : {
		required : true,
		pattern : /^[0-9]+$/,
		conditional : function(value) {

			return Number(value) > 17;
		}
	}
});
