title: jquery: use (“parent > child”) with variables
body: <p>For example I have a <code>&lt;div class="first"&gt;</code> containig other <code>&lt;div&gt;</code> 's and selected first one and pushed him into variable</p>
  
  <pre><code>variable = $('div.first')
  </code></pre>
  
  <p>And now I want something like this</p>
  
  <pre><code>$(variable + " &gt; div")
  </code></pre>
  
  <p>I know, it seems stupid but what if I had an array containig table rows and I need to access columns inside a specific row:</p>
  
  <pre><code>var tableRows = $('table &gt; tbody &gt; tr');
  var tableBodyCols = $(tableRows[i]+'&gt; td'); // Doesn't work :(
  </code></pre>
