推荐答案

窗口消息传递（ window.postMessage [ ^ ]）

你可以通过Window Message Passing来做到这一点（ window.postMessage [ ^ ]），当两者都在不同的域中时。



对于你的情况，父母会给孩子发一条消息，孩子会有一个听众听这个消息。



代码可能如下所示。

Window Message Passing(window.postMessage[^])
You can do this by Window Message Passing(window.postMessage[^]), when both are in different domains.

For your case, the parent will post a message to child and there will be a listener in child to listen to this message.

The code may be like below in parent.

childWindow.postMessage(message, targetOrigin);

和孩子的倾听者会是这样的。

And the listener in child will be like.

var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";

// Listen to message from parent window
eventer(messageEvent,function(e) {
    message = e.data; // This is the "message" passed from parent.
 },false);

这可以从任何一方完成。我的意思是你也可以从孩子到父窗口进行交流。

请尝试实施...

This can be done from either side. I mean you can also communicate from child to parent window.
Please try to implement...
