遍历一个JS对象的属性和方法

示例代码如下：
[html] view plaincopyprint?
  1. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">  
  2. <html>  
  3. <head>  
  4. <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">  
  5. <title>testExtjs4</title>  
  6.  <script type="text/javascript" src="../js/classextends1.js"></script>   
  7. <script type="text/javascript">  
  8.     for (pro in document){  
  9.         document.write("document."+pro+"="+document[pro]+"<br>");  
  10.     }  
  11. </script>  
  12.   
  13. </head>  
  14. <body>  
  15.   
  16. </body>  
  17. </html>

 <script type="text/javascript" src="../js/classextends1.js"></script> 
<script type="text/javascript">
	for (pro in document){
		document.write("document."+pro+"="+document[pro]+"<br>");
	}
</script>

</head>
<body>
