title: how to run a method after jQuery validate has been run
body: <p>Our company uses jquery validate and I want to update some fields AFTER validate has been run and whether the form is valid. It would seem like there should be some callback or chaining method but I don't really see it in the docs. Any idea how to do this? </p>
  
  <p>I have something like this: </p>
  
  <pre><code>  $('#signup-form-step-one').validate({
      rules: form_rules,
      messages: form_messages,
      errorClass: 'error',
      errorPlacement: function (err, element) {
        console.log('there is an error!!!!');
        setToDisabled();
        err.insertAfter(element);
      },
      submitHandler: function (form) {
        console.log(form);
        form.submit();
      }
    });
  </code></pre>
  
  <p>and if there are any errors, set the submit button to disabled. Any ideas?</p>
