title: jQuery add text to span within a div
body: <pre><code>&lt;div id="tagscloud"&gt;
         &lt;span&gt;&lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How would I do to add some text within the span like code below ?</p>
  
  <p><code>&lt;span&gt;**tag cloud**&lt;/span&gt;</code></p>
  
  <p><strong>Edit</strong>:
  actually the span has an id</p>
  
  <pre><code>&lt;div id="tagscloud"&gt; &lt;span id="WebPartCaptionWPQ2"&gt;&lt;/span&gt; &lt;/div&gt;
  </code></pre>
