How can I target an element's 'parent'
<p>I have some <code>&lt;TD&gt;s</code> without unique names. Inside them there are spans with unique classnames so I have no problem targetting the spans. How can I target the parent <code>&lt;td&gt;</code> so I can change its class?</p>

<p>I want to do something like  <code>$(".classname").parent("TD").className="newClassclassname"</code>.</p>
