title: jQuery validate doesn't validate an input on keyup until it has lost focus once
body: <p>I have a form with validation using <a href="http://docs.jquery.com/Plugins/Validation" rel="nofollow">jQuery validation</a>.  This works perfectly however, my form always contains default values:</p>
  
  <pre><code>&lt;input type="text" value="0" name="myname" class="required number error"&gt;
  </code></pre>
  
  <p>When a user first changes the values in the input boxes, no validation occurs until the input loses focus. After this first time any keyup / change event inside the input will result in validation.</p>
  
  <p>How can I force the validation to occur on keyup / change ALL the time as opposed to after an initial change.</p>
