title: Find all elements based on ids using regex on jQuery selector
body: <p>I've got several elements with unique ids like so:</p>
  
  <pre><code>&lt;div id='item-1-top'&gt;&lt;/div&gt;
  &lt;div id='item-2-top'&gt;&lt;/div&gt;
  &lt;div id='item-3-top'&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I was hoping that the following would work using jQuery:</p>
  
  <pre><code>$("#item-[.]+-top").each(function() {
    $(this).hide();
  });
  </code></pre>
  
  <p>I do not have a good grasp of regular expressions and I would appreciate some input, as the above appears to be incorrect.</p>
