title: Set reCaptcha field as required
body: <p>I use the new reCaptcha with <a href="http://jqueryvalidation.org" rel="nofollow">the jQuery Validate</a> plugin. The validation plugin works nice with my form but unfortunately it didn't work with reCaptcha. My attempt to make it work below:</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;div class="g-recaptcha" name="recaptcha" id="recaptcha" data-sitekey="XXXXX"&gt;&lt;/div&gt; 
  </code></pre>
  
  <p>Javascript:</p>
  
  <pre><code> recaptcha: {
      required: true
        }    
  </code></pre>
  
  <p>but it didn't worked. Does anyone know how to fix this. I simply need the default <strong>This field is required</strong> error message.</p>
