title: Adding class to child element by parent Element ID and Child Class
body: <p>I think I got this wrong "$('#groupdepID01 > .lahatkami')" 
  $('ID > Class')</p>
  
  <p>script</p>
  
  <pre><code> $('#groupdepID01 &gt; .lahatkami').addClass('iamSelected');
  </code></pre>
  
  <p>html</p>
  
  <pre><code>&lt;div id="groupdepID01"&gt;
       &lt;input class="lahatkami" id="01" /&gt;
  &lt;/div&gt;
  
  &lt;div id="groupdepID02"&gt;
       &lt;input class="lahatkami" id="02" /&gt;
  &lt;/div&gt;
  
  &lt;div id="groupdepID04"&gt;
       &lt;input class="lahatkami" id="03" /&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Expected Output should be</p>
  
  <pre><code>&lt;div id="groupdepID01"&gt;
       &lt;input class="lahatkami iamSelected" id="01" /&gt;
  &lt;/div&gt;
  
  &lt;div id="groupdepID02"&gt;
       &lt;input class="lahatkami" id="02" /&gt;
  &lt;/div&gt;
  
  &lt;div id="groupdepID03"&gt;
       &lt;input class="lahatkami" id="03" /&gt;
  &lt;/div&gt;
  </code></pre>
