title: Parse JavaScript with jsoup
body: <p>In an <code>HTML</code> page, I want to pick the value of a <code>javascript</code> variable.<br />
  Below is the snippet of <code>HTML</code> page:</p>
  <pre><code>&lt;input id=&quot;hidval&quot; value=&quot;&quot; type=&quot;hidden&quot;&gt; 
  &lt;form method=&quot;post&quot; style=&quot;padding: 0px;margin: 0px;&quot; name=&quot;profile&quot; autocomplete=&quot;off&quot;&gt;
  &lt;input name=&quot;pqRjnA&quot; id=&quot;pqRjnA&quot; value=&quot;&quot; type=&quot;hidden&quot;&gt;
  &lt;script type=&quot;text/javascript&quot;&gt;
      key=&quot;pqRjnA&quot;;
  &lt;/script&gt;
  </code></pre>
  <p>My aim is to read the value of variable <code>key</code> from this page using <code>jsoup</code>.<br />
  Is it possible with <code>jsoup</code>? If yes then how?</p>
