title: jQuery match regex
body: <pre><code>var playerClass = $(this).parent().attr('class')
  </code></pre>
  
  <p>Question about only selecting a specific class from the dom.</p>
  
  <p>What can I add to this line to only select the class that has a class of player-1, player-2, basically anything with a prefix of player- followed by a number?</p>
