2个窗口之间的JavaScript通信

Question

I am using window.open to open 2 new windows from my web page and these 2 new windows are of different domains. My requirement is that from one window I want to change the URL of the other window and vice versa. Is there any way to achieve this?

Answer 1

Yes, this is possible. Have a look at window.postMessage .

The syntax looks like:

otherWindow.postMessage(message, targetOrigin, [transfer]);

Where otherWindow is a reference to another window. window.open returns such a reference.
