JavaScript get attribution from select
<p>Consider:</p>

<pre><code>&lt;select id="test"&gt;
   &lt;option attribut="1"&gt;test 1&lt;/option&gt;
   &lt;option attribut="2"&gt;test 2&lt;/option&gt;
   &lt;option attribut="3"&gt;test 3&lt;/option&gt;
   &lt;option attribut="4"&gt;test 4&lt;/option&gt;
   &lt;option attribut="5"&gt;test 5&lt;/option&gt;
&lt;/select&gt;
</code></pre>

<p>I want to get the selected item's attribute. Is there any simple way to do it? The native JavaScript is fine.</p>
