title: jQuery select element in sibling's "td"
body: <p>HTML is  </p>
  
  <pre><code>&lt;tr&gt;  
      &lt;td&gt;&lt;input /&gt;&lt;/td&gt;  
      &lt;td&gt;&lt;a&gt;ref&lt;/a&gt;&lt;/td&gt;  
  &lt;/tr&gt;
  </code></pre>
  
  <p>I got<br>
  <code>$('a')</code></p>
  
  <p>What is the most optimal way to get <code>&lt;input /&gt;</code> from this ?<br>
  If they are together <code>&lt;input /&gt;&lt;a&gt;&lt;/a&gt;</code>, i can use <code>$('a').sibling('input')</code>, but they are in different td's</p>
