jQuery change text in link
<p>I have a simple question for jQuery...</p>

<p>I have a table with a link like this</p>

<pre><code>&lt;table&gt;
  &lt;tr&gt;
    &lt;td class="views-field"&gt;
      &lt;a href="ciao"&gt;201105&lt;/a&gt;
    &lt;/td&gt;
  &lt;/tr&gt;
&lt;/table&gt;
</code></pre>

<p>Now I would change the link's text from 201105 to 2011-05</p>

<p>(simple add a "-" after the first 4 characters)</p>

<p>I tried substring but don't work... Help me!!</p>
