News ticker with jquery and without use of plugins
<p>I have a part in a website that I need to show as a news ticker.</p>

<p>It looks like this:</p>

<pre><code>&lt;div class="news"&gt;
  &lt;span&gt;NEWS 1&lt;/span&gt;
  &lt;span&gt;NEWS 2&lt;/span&gt;
  &lt;span&gt;NEWS 3&lt;/span&gt;
&lt;/div&gt;
</code></pre>

<p>I need a javascript code to show news repeatedly without using plugins. The idea is to show a <code>span</code> and hide the rest of <code>spans</code> and repeat with order each <code>n</code> seconds.</p>

<p>How can I do that ?</p>
