Redirect parent from iFrame

Question

在iframe中单击网址后，如何重定向父窗口？

Answer 1

Setting a link's target property to _top will cause the link to open in the topmost frame; setting it to _parent will open it in the parent frame.

<a href="index.html" target="_parent">Open link in parent frame</a>

If that's not the correct answer, please clarify what you mean.
