title: Why is ('.class', this) not working?
body: <p>Both of these scripts are not working with JQuery Mobile</p>
  
  <p>JS</p>
  
  <pre><code>$(this).find('.class').on("tap",function(){
    $( ".class-hidden" ).toggle( "slow" );
  });
  
  
  $('.class', this).on("tap",function(){
    $( ".class-hidden" ).toggle( "slow" );
  });
  </code></pre>
  
  <p>HTML</p>
  
  <pre><code>&lt;div class="class"&gt;
      &lt;div class="class-hidden"&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Is there any reason either of these functions would not work with the below text?</p>
