title: jQuery no conflict issue
body: <p>I used jQuery many times in noconflict mode as below </p>
  
  <pre><code>var $j = jQuery.noConflict();
  </code></pre>
  
  <p>and it works great every time.</p>
  
  <p>Today, I used the jQuery 'before after' plugin. I used the same noconflict function but it did not work <a href="http://www.catchmyfame.com/2009/06/25/jquery-beforeafter-plugin/" rel="nofollow noreferrer">http://www.catchmyfame.com/2009/06/25/jquery-beforeafter-plugin</a>/ </p>
  
  <p>I am not sure that <strong>$.fn.extend</strong> works with no conflict or not. Please help thanks</p>
