title: Shortcut Limit jQuery to Specific DOM Node
body: <p>I want restrict jQuery to specific namespace or DOM node. Currently what I do is something lik this on every line</p>
  
  <pre><code>$('a' , $node).addClass();
  $('li' , $node).removeAttr();
  $('div#q' , $node).hide();
  </code></pre>
  
  <p>And so on.. Is there any shortcut/method which I can specify after which the scope of jQuery object will be limited to <code>$node</code>.</p>
