iframe跨源报错:"Blocked a frame with origin from accessing a cross-origin frame"

一、报错信息：

　　“Blocked a frame with origin from accessing a cross-origin frame”

二、在stackoverflow上找到原因

Same-origin security policy

You can't access an <iframe> with Javascript, it would be a huge security flaw if you could do it. For the same-origin policy browsers block scripts trying to access a frame with a different origin.

（同源策略）

Origin is considered different if at least one of the following parts of the address isn't maintained:

<protocol>://<hostname>:<port>/path/to/page.html

Protocol（协议）, hostname（主机名） and port（端口） must be the same of your domain, if you want to access a frame.

iframe调用父页面的函数：parent.functionNme();

ps:如果报以上错误，把iframe和父页面代码都放入工程项目中在本地跑起来即可解决同源问题。
