Determine if html select contains a value in any of its child options
<p>Given a select</p>

<pre><code>&lt;select id="Myselect"&gt;
&lt;option value="-1"&gt;Please Select&lt;option&gt;
&lt;option value="1"&gt;Selection 1&lt;option&gt;
&lt;option value="2"&gt;Selection 2&lt;option&gt;
&lt;/select&gt;
</code></pre>

<p>What the best way to determine if there is an option of value X in the select with JQuery?</p>
