Find serial number of child
<p>Suppose that I've a given html code:</p>

<pre><code>&lt;ul class="fmenu123"&gt;
    &lt;li&gt;city&lt;/li&gt;
    &lt;li&gt;service&lt;/li&gt;
    &lt;li&gt;hour&lt;/li&gt;
&lt;/ul&gt;
</code></pre>

<p>There are in jquery function <code>children</code> and selector <code>nth-child</code>. But how could I find a serial number of "mouseovered" child of this <code>ul</code> element - ie number <code>n</code> such that nth child of <code>ul</code> is exactly this chosen element? Which is the simplest method in jquery to find this?
Thanks in advance.</p>
