title: appending to showError function in jquery validation and jquery.validate.unobtrusive
body: <p>I'm using a third party tool that uses</p>
  
  <ul>
  <li>jquery.validate.min.js</li>
  <li>jquery.validate.unobtrusive.min.js</li>
  </ul>
  
  <p>when i enter the following which shows a messagebox. The custom validation on  the tool validatiion fails. I would assume it also uses "showError". I appreciate this is hard question to ask with out the full code base. My question is...</p>
  
  <p>Is there an event that occurs after <code>showErrors</code>. Or is there a way to extend to this function as opposed to overriding it. </p>
  
  <pre><code>$.validator.setDefaults({
     showErrors: function (errorMap, errorList) {
          $(".messagebox").show();
      }
  });
  </code></pre>
