This article is wrong. You need to use prototype when defining your functions.

Here is how to do it:

  <html>
  <head>
  <script>

  function HotDog () {
	this.name=arguments[0];
  } 

  HotDog.prototype.name=null;

  HotDog.prototype.getCondiments= function () { 
	document.getElementById('test').innerHTML='started...'  +this.name;
  };
  var myHotDog = new HotDog('test 001');

  window.onload= function() {
	setTimeout(30, myHotDog.getCondiments());
  };

  </script>

  </head>
  <body>
  <div id=test>loading...</div>
  </body>
  </html>
