js top.location判断自身是否是顶级窗口
如果要在js中来判断自身是否是顶级窗口我们可直接利用top.location!=self.location来加以操作，具体看下面代码
顶级窗口的地址:top.location
本窗口的地址:self.location
代码如下:
- if(top.location!=self.location){
- top.location = self.location;
- }
具体实现程序,代码如下:
- if (window.top !== window.self) { // are you trying to put self in an iframe?
- try {
- if (window.top.location.host) { // this is illegal to access unless you share a non-spoofable document domain
- // fun times
- } else {
- bust(); // chrome executes this
- }
- } catch (ex) {
- bust(); // everyone executes this
- }
- }
