title: jQuery selector :contains - Use regular expressions
body: <p>I am trying to implement search functionality for a list using jQuery. I am using following line to filter matching elements</p>
  
  <pre><code>$(list).find("a:contains(" + filter + ")").parent().show();
  </code></pre>
  
  <p>This shows all the elements which contain "filter" text. I want to show only those elements in which words start with "filter" text.</p>
  
  <p>I am thinking of using regular expression for this.</p>
  
  <p>Is there any way to pass regular expression to <code>:contains</code> selector? Or can this be achieved in any other way?</p>
