title: how to change height of iframe when it loads?
body: <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$('#song-link').change(function () {
    var link = $('#song-link').val();
    SC.oEmbed(link, {
      element: document.getElementById('putTheWidgetHere')
    });
  });</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script src="https://connect.soundcloud.com/sdk/sdk-3.1.2.js"&gt;&lt;/script&gt;
  &lt;input  id="song-link" placeholder="Paste Soundcloud link here" name="song_link"   type="text"&gt;
  &lt;div id="putTheWidgetHere"&gt;&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Code helps me to preview the link of soundcloud. You can test its works fine. but i want to change its height from <code>400px</code> to <code>200px</code>. I have tried adding <code>addclass()</code> and <code>css()</code>. But it didn't work.    </p>
  
  <p>I couldn't figure which event will trigger these functions since the height must be set after the link is pasted on input text and loads on the <code>iframe</code> that soundcloud loads.   </p>
