jQuery: How to calculate the maximal attribute value of all matched elements?
<p>Consider the following HTML:</p>

<pre><code>&lt;div class="a" x="6"&gt;&lt;/div&gt;
&lt;div class="a" x="9"&gt;&lt;/div&gt;
&lt;div class="a" x="2"&gt;&lt;/div&gt;
...
&lt;div class="a" x="8"&gt;&lt;/div&gt;
</code></pre>

<p>How would you find the maximal <code>x</code> value of all <code>.a</code> elements ?</p>

<p>Assume that all <code>x</code> values are positive integers.</p>
