Use document.write.

<html>
  <head>
    <script language="Javascript">
      <!--
      var newContent='<html><head><script language="Javascript">function Hi() {alert("Goodbye World");}</script></head><body onload="Hi();">New Content</body></html>';
      function ReplaceContent(NC) {
        document.open();
        document.write(NC);
        document.close();
      }
      function Hi() {
        ReplaceContent(newContent);
      }
      -->
    </script>
  </head>
  <body>
    Original Content
    <a href="javascript:Hi()">Replace</a>
  </body>
</html>

var script = document.createElement('script');
script.src = 'http://code.jquery.com/jquery-1.7.2.min.js';
script.type = 'text/javascript';
document.getElementsByTagName('head')[0].appendChild(script);

Script

javascript:document.open('text/html');document.write('<!DOCTYPE HTML><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>HAI</title></head><body><h1>OMG HAI2U!!!1</h1></body></html>');document.close();

DOM snapshot of the resulting page

<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>HAI</title></head><body><h1>OMG HAI2U!!!1</h1></body></html>

document.getElementsByTagName("html")[0].innerHTML Contains both head and body tags. I Usually avoid document.open\write\close
