SELECT value in Javascript
<p>I have this SELECT element which i want to update the current url to URL&amp;number=VALUE of selected item.</p>

<p>However, i can't figure how to catch the value.</p>

<pre><code>&lt;select name="prside" onchange="document.location.href = document.location.href + '&amp;number=' + VALUE&gt;
    &lt;option&gt;Annoncer pr. side&lt;/option&gt;
    &lt;option value="5"&gt;5&lt;/option&gt;
    &lt;option value="10"&gt;10&lt;/option&gt;
    &lt;option value="20&gt;20&lt;/option&gt;
    &lt;option value="40"&gt;40&lt;/option&gt;
&lt;/select&gt;
</code></pre>
