title: jQuery Validation Plugin cannot Validate on Keyup
body: <p>I use jQuery Validation Plugin and my form can be validated as below (let's say I have 2 fields A and B):</p>
  
  <p><strong>It Works:</strong> <br/>
  I <strong>clicked A</strong> and type something and then delete. Then I <strong>clicked B</strong>. In that case validation message is shown.</p>
  
  <p><strong>It DOES NOT Work:</strong><br/>
  I **clicked A and do not type nothing. Then I clicked B. In that case the related validation message related to field A is not shown. But I want it to shown as above. </p>
  
  <p>I tried to use onsubmit, onkeyup and onclick parameters in validate method, but it did not make any sense. How can I provide this?  </p>

  <pre><code>jQuery(function () {
      $.validator.setDefaults(
      $("#myform").validate({
          //onsubmit: false, ???
          //onkeyup: true, ???
          //onclick:true, ???
          onkeyup: function(element){this.element(element);},
          rules: {
              'Applicant.Name': "required",
              'Applicant.Surname': "required"
          },
          messages: {
              'Applicant.Name': "Please enter your Name",
              'Applicant.Surname': "Please enter your Surname"
          }
      })
  ); 
  
  });
