title: jQuery Validate select on change
body: <p>I am using jQuery Validate plugin in my forms and I need to validate selects when users select any option to display the error immediately, now I'm using 'onfocusout' option for inputs and textareas, but obviously is not a good practice to wait for focus out when using a select.</p>
  
  <p>If it helps in something, here's the code that I'm using right now to validate my forms:</p>
  
  <pre><code>$('form#cars').validate({
      onfocusout: function(e){
          this.element(e);
      },
      errorElement: 'span',
      errorClass: 'error help-inline',
      highlight: function(element, errorClass, validClass){
          $(element).addClass(errorClass).removeClass(validClass);
          $(element).closest('.control-group').addClass(errorClass);
      },
      unhighlight: function(element, errorClass, validClass){
          $(element).removeClass(errorClass).addClass(validClass);
          $(element).closest('.control-group').removeClass(errorClass);
      },
      messages: {
          'vehicle_city': 'Debes especificar la cuidad donde circula tu auto.'
      }
  });
  </code></pre>
  
  <p>Someone knows the method to do what I want? Is there a way?</p>
