先看看防止网页被Frame框架调用的JS代码：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/gcs/43740.html
<script language="javascript">
if(window.self != window.top){
window.top.location.replace(window.self.location);
}
</script>原理是判断window.self是否等于window.top。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/gcs/43740.html

<title>使用JS防止网页被Frame框架调用</title>
<script language="JavaScript">
//网页如果被iframe引用，用此页强行代替父页
if(window.self != window.top){
window.top.location.replace(window.self.location);
}
</script>
</head>
<body>
这是被iframe引用的页面

</html>破解方法文章源自菜鸟学院-https://www.cainiaoxueyuan.com/gcs/43740.html
// 顶层窗口中放入代码 var location = document.location; // 或者 var location = "";
范例代码

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>iframe引用网页范例</title> <script language="javascript"> var location = document.location; </script> </head> <body> <iframe src="js-no-iframe.html" style="width:600px;height:350px;border:1px;"></iframe> </body> </html>
从该范例看到，网页并不能被成功引用，所谓的破解代码并没有效果文章源自菜鸟学院-https://www.cainiaoxueyuan.com/gcs/43740.html
