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);
