title: How to validate form field when you press tab?
body: <p>How does it possible to review/valid each field on the form when you press <strong>TAB</strong> key. Currently it works only if you start typing in the box. There is a <a href="http://jsfiddle.net/p5peypct/1/" rel="nofollow">fiddle.js</a>.</p>
  
  <p>I'm using <a href="http://validatejs.org/" rel="nofollow">validatejs</a> script with these options:</p>
  
  <pre><code>$('#form').validate({ // initialize the plugin
      success: function(label) {
          label.addClass("valid");
      },
      rules: {
          formFName: {
              required: true,
              minlength: 2
          },
          formLName: {
              required: true,
              minlength: 2
          },
          formEmail: {
              required: true,
              email: true
          }
      },
      messages: {
          formFName: {
              required: "Enter your first name, please.",
              minlength: "A name usually has at least 2 characters, right?"
          },
          formLName: {
              required: "Enter your last name, please.",
              minlength: "A name usually has at least 2 characters, right?"
          },
          formEmail: {
              required: "Enter your email address, please.",
              email: "Enter an existing email address, please."
          }
      },
      submitHandler: function (form) {
          alert('sent');
      }
  });
  </code></pre>
