The jQuery Validation Plugin provides drop-in validation for your existing forms, while making all kinds of customizations to fit your application really easy.

This project is looking for help! You can donate to the ongoing pledgie campaign and help spread the word. If you've used the plugin, or plan to use, consider a donation - any amount will help.

You can find the plan for how to spend the money on the pledgie 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.validation.js"></script>
<script>
$("form").validate();
</script>

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