6.如何保证自己的页面不被别人用IFRAME框架嵌套

重点是对层的判断：

被框架加载的页面不能放入最顶层top层，

所以可以通过判断top层

 1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2     pageEncoding="UTF-8"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 <html>
 5 <head>
 6 <title>标题页</title>
 7 <script language="javascript">
 8 if(self!=top){
 9 top.location=self.location;    //判断是否是最顶层，不是则将当前页设置为最顶层
10 }
11 </script>
12 </head>
13 <body>
14     AAAAAAAAAA
15 </body>
16 </html>

 1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2     pageEncoding="UTF-8"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 <html>
 5 <head>
 6 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 7 <title>Insert title here</title>
 8 </head>
 9 <body>
10     BBBB
11     <iframe src="1.jsp"></iframe>
12 </body>
13 </html>
