title: hide a specific div from html ajax response
body: <p>I am not experimented with ajax.</p>
  
  <p>I have this html ajax response and I want to hide the first div 'loading' after ajax success</p>
  
  <p>Response : </p>
  
  <pre><code>&lt;div id="loading"&gt;
    &lt;label&gt;..&lt;/label&gt;
    &lt;div&gt;...&lt;/div&gt;
  &lt;/div&gt;
  &lt;div id="list"&gt;
  ...
  ...
  &lt;/div&gt;
  </code></pre>
  
  <p>I have tried a lot of things : </p>
  
  <pre><code>success: function (response) {
    response.find('#loading').html().hide();
    response.filter('#loading').hide();
    response.find('#loading').hide();
  }
  </code></pre>
  
  <p>But that does not work. </p>
