如何利用js在两个html窗口间通信

var domain = 'http://127.0.0.1:10001';

window.open('http://127.0.0.1:10001/B.html');
window.addEventListener('message', function (event) {
    if (event.origin !== domain) return;
    console.log('message received:  ' + event.data, event);
}, false);

var domain = 'http://127.0.0.1:10001';
window.opener.postMessage("suess", domain);
window.close();

// 发送数据方
var domain = 'http://127.0.0.1:10001';
var myPopup = window.open('http://127.0.0.1:10001/B.html');
myPopup.postMessage('数据', domain);

// 接收数据方
window.addEventListener('message', function(event) {
    if(event.origin !== 'http://127.0.0.1:10001') return;
    console.log('message received:  ' + event.data,event);
},false);
