动态生成 iframe

There iframes are generated dynamically

推荐答案

你也可以将 name 和 ID 设置为相等的值

Also you can set name and ID to equal values

<iframe id="frame1" name="frame1" src="any.html"></iframe>

这样你就可以在子页面中使用下一个代码

so you will be able to use next code inside child page

parent.document.getElementById(window.name);
