javascript - Permission denied to access property 'href'

Question

I try to reload parent web page from iframe. Here is my code:

 <script>
$(document).ready(function() {
  window.parent.location.href = window.parent.location.href;      
});
 </script>

But it doesn´t work. Firebug says: Permission denied to access property 'href'

I´m on same domain so what´s the problem? I try to do it in Wordpress theme.

Answer 1

只有当父子节点从相同的协议（http/https）、相同的主机和相同的端口运行时，您的代码才能工作。这称为同源策略 (SOP)。您可以查看以下参考： http ://en.wikipedia.org/wiki/Same_origin_policy

Answer 2

您可以document.domain="domainName:port"在 Firefox 中设置。不能设置端口的默认值，如果端口不同，请自行设置！</p>
