title: jQuery and .length>0
body: <pre><code>var sd = jQuery(".bla");
  if (sd.length&gt;0){
  
  }
  </code></pre>
  
  <p>Is there any cooler way to write that code? I want some code to execute only if there are some classes named <code>bla</code>. I do know I can use the each, but I do not want to and I do know I can do stuff like <code>sd.action()</code>, but I do not want to.</p>
