Associate an element placed out of tab with tab items
<p>I have a tab script that works:</p>

<p><a href="http://jsfiddle.net/fmqeh/8/" rel="nofollow">http://jsfiddle.net/fmqeh/8/</a></p>

<p>With click on ".tab" items, ul.tab li items has class "actives". But with click on </p>

<pre><code>&lt;a class="bdn" href="#tab2"&gt;Go to Tab 2&lt;/a&gt;
</code></pre>

<p><code>&lt;a class="bdn"&gt;</code> couldnt add  <code>class="actives</code> to tab items. How can I do this with scroll to </p>

<pre><code>&lt;div class="tab_content chart" id="tab2"&gt;
    this is the content of tab2
&lt;/div&gt;
</code></pre>

<p>Thanks in advance</p>
