This is how you set the parent of the frame (top) to the location of the frame document...
这就是将框架 ( top)的父级设置为框架文档位置的方式...
top.location = self.location;
Of course, this code must be executed within the iframe, and is succeptible to the Same-Origin Policy.
当然，此代码必须在 iframe 内执行，并且可以接受同源策略。

window.top.location is return you to broswer's address bar location even you'r in i-frame or page.. window.location is return location of your current page address in case facebook apps. if you want to top query-string you have to use
即使您在 i-frame 或页面中，window.top.location 也会将您返回到浏览器的地址栏位置。 window.location 是您当前页面地址的返回位置，以防 facebook 应用程序。如果你想顶部查询字符串，你必须使用
alert(window.top.location);
alert(window.top.location);
if u want to replace top location then
如果你想替换顶部位置，那么
window.top.location = "http://whatever.com";
window.top.location = "http://whatever.com";
