title: Clear error message or reset validation using jQuery Validation plugin
body: <p>I am a newbie to jQuery and I aplogize if this question is very basic.</p>
  
  <p>I am using <em>bassistance's Valiation</em> plugin to validate a simple form. One of the text fields is mandatory - so I set <strong>required</strong> flag under <em>rules</em> and a corresponding message under <em>messages</em>. The problem I have is, once the validation kicks in, the error message I've set is displayed even if the field is blank (meaning, if the user deletes the contents of the field to start from scratch). Is there anyway to clear the error message or reset the validation if the field becomes empty? I tried to use the resetForm(), but looks like I can't use it while it's still validating. Here's part of the code:</p>
  
  <p>$(document).ready(function() {</p>
  
  <pre><code>  var validator = $("#form1").validate({
       rules: {
           fname: {
               required: true,
               remote: 'http://localhost/check_name.php'  
           }
         },
       messages: {
           fname: {
               required: "Enter a valid jobname. eg: 99999_Disney",
               remote: "Name already exists";
                      }   
  
                 } 
    });
  </code></pre>
  
  <p>Thanks for your help!</p>
