js关闭被打开的iframe页面,并在新窗口打开

示例代码:

$(function(){
    console.log(window.location.href)
    if (self.frameElement && self.frameElement.tagName == "IFRAME") {
        // alert('在iframe中');
        window.open(window.location.href)

        parent.location.reload(true);
        var index = parent.layer.getFrameIndex(window.name);
        parent.layer.close(index);
    }
   });

 

相关知识补充:
判断页面是否被iframe有三种方法
//方式一
if (self.frameElement && self.frameElement.tagName == "IFRAME") {
  alert('在iframe中');
}
//方式二
if (window.frames.length != parent.frames.length) {
  alert('在iframe中');
}
//方式三
if (self != top) {
alert('在iframe中');
}

 

禁止页面被别人iframe

<script language="javascript">
if (top.location != location)
{
top.location.href = location.href;
}
</script>


//
<script language="javascript">
if(self!=top){top.location.href=self.location.href;}
</script>

 

注: 这种做法虽简单,但如果对方用如下招数很容易就被破解了

<iframe src="你的页面地址" name="tv" marginwidth="0" marginheight="0" scrolling="No" noResize frameborder="0" id="tv" framespacing="0" width="580" height="550" VSPACE=-145 HSPACE=-385></iframe>
<script language="javascript">
var location="";
var navigate="";
frames[0].location.href="";
</script>

 

当然,万能的js依旧设计了应对招数

<script language="javascript">if(top != self){location.href = "about:blank"; //也可设置为你自己的URL}</script>

 

但这种方式会禁止所有的页面的嵌入,那么本域名内的页面嵌入也是被禁止
下面做到禁止除域名外的页面的iframe 
<script language="JavaScript">
try{
  top.location.hostname;
  if (top.location.hostname != window.location.hostname) {
    top.location.href =window.location.href;
  }
}
catch(e){
  top.location.href = window.location.href;
}
</script>
