getting a custom tag value using jquery
<pre><code>&lt;select id="selTest"&gt;
    &lt;option custom="123" value="abc"&gt;111&lt;/option&gt;
    &lt;option custom="456" value="def"&gt;222&lt;/option&gt;
&lt;select&gt;
</code></pre>

<p>...using jQuery, <strong>how do I get option.custom where option.value=selTest.val()</strong></p>

<p>in other words: if selTest.val = def, then $x=456 (I'm trying to get the value of custom into $x)</p>
