HTML5-跨浏览器iframe后消息-子级到父级？

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

// Listen to message from child windoweventer(messageEvent,function(e) {    var key = e.message ? "message" : "data";    var data = e[key];    //run function//},false);

可以与父页面中的上述内容以及子页面中的以下内容一起使用-

parent.postMessage("loadMyOrders","*");  //  `*` on any domain
