title: How to put jQuery :gt() dynamically?
body: <p>There is a jQuery <code>:gt()</code> selector which allows to select all elements at an index greater than index within the matched set.</p>
  
  <p>I can use it like this:</p>
  
  <pre><code>$(this).find('a:gt(30)');
  </code></pre>
  
  <p>The problem is that I'm using a var instead:</p>
  
  <pre><code>var opt = $("#div").text();
  </code></pre>
  
  <p>How do I set the <code>:gt()</code> selector next to the variable:</p>
  
  <pre><code>var opt = $("#div").text();
  
  $(this).find(opt:gt(30));
  </code></pre>
  
  <p>This doesn't seem to work.</p>
