title: jquery selection method
body: <pre><code>   &lt;script&gt;
              $("*", document.body).each(function () {//is document.body a context?
                  var parentTag = $(this).parent().get(0).tagName;
                  //Above statement is only selecting the body tag why?
  
                  $(this).prepend(document.createTextNode(parentTag + " &gt; "));
              });
      &lt;/script&gt;
    &lt;/body&gt;
  &lt;/html&gt;       
  </code></pre>
  
  <p>Is there any reason for selecting only body tag in the above script?Also is document.body a context?since document.body is not quoted will it be a context?</p>
