title: Change title iframe (that has no id) within a div
body: <p>I'm trying to figure out how to add a title to a iframe that has no 'id' using javascript.</p>
  
  <p>The code is like this:</p>
  
  <pre><code>&lt;div class="review-right"&gt;
  &lt;div&gt;
  &lt;iframe&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And I want to get this:</p>
  
  <pre><code>&lt;div class="review-right"&gt;
  &lt;div&gt;
  &lt;iframe title="Sample"&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>This is what I've tried:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  $(document).ready(function(){
     $(".review-right iframe").attr('title', 'Sample');
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>I'm a noob at jquery so I don't know if this is even right.</p>
