title: The showErrors() function of jQuery Validation Plugin
body: <p>The following script works fine:</p>
  
  <pre><code>$("#regform").validate().showErrors({"username":"message"});
  </code></pre>
  
  <p>After I changed the script to the below one, it doesn't work.</p>
  
  <pre><code>var name = "username";
  $("#regform").validate().showErrors({name:"message"});
  </code></pre>
  
  <p>I need to pass the field name by a variable. Anyone knows how this problem can be solved?</p>
