iFrame之间的通信？ [英] Communication between iFrames?

问题描述

你如何让两个iFrames彼此交谈？
例如，我是第二个iframe的元素值，第一个iframe上有显示元素。我需要将第二帧的值降到第一帧。我将如何做到这一点？
不要说使用cookies，会导致数据量巨大的伤害。

How can you make two iFrames talk to each other? For example I was a element value off the 2nd iframe and the 1st iframe has the display element on it. I need to get the value off the 2nd frame to the 1st. How would I do this? Don't say use cookies, cause that will hurt with massive sum of data.

推荐答案

如果< iframe> 元素由同一个域提供，那么他们可以直接访问对方。例如，在 iframe1 中你可以这样做：

If the <iframe> elements are served from the same domain, then they can access each other directly. For example, in iframe1 you could do:

document.getElementById('someDiv').innerHTML = 
    top.document.getElementById('otherIframe').contentWindow.
    document.getElementById('someOtherDiv').innerHTML;
