To get started your going to need jQuery and a reference to the library in your page.
<script type="text/javascript" src="js/jquery.min.js"></script>
Then your going to need to link to the Easy Validate plugin. Make sure jQuery is reference first in your document.
<script type="text/javascript" src="js/jquery.easyValidate.min.js"></script>
Next, you need to reference the default style sheet for the plugin.
<link rel="stylesheet" type="text/css" href="styles/easyValidate.default.css" media="screen">
Finally you need to apply the field validations to each field by their **class** attribute. For more information on the validators please see documentation.
<input type="text" name="txt_name" class="required" value="">
<input type="text" name="txt_email" class="required email" value="">
Basic initialization
$(function(){
$(’#yourForm’).easyValidate();
});
