阴止页面被其它网站iframe调用代码

在ie下载

<script type=”text/网页特效>
if(window!=parent)
parent.navigate(window.location.href);
</script>

在firefox下载

<script type=”text/网页特效>
if (top.location !== self.location) {
top.location=self.location;
}
</script>

还有用php教程来实例

<?php
$url = $_server['http_host'];
if( $url != 'www.111cn.net' )
{
 exit();
}
　?>
