html5 postMessage 消息传递问题

<script type="text/javascript">
        $.fn.extend({
            addEvent: function (type, handle, bool) {
                var el, thisLen = this.length;
                bool ? bool = bool : bool = false;
                if (thisLen == 1) {
                    el = this[0];        //jquery对象转成 js对象
                    el.addEventListener ? el.addEventListener(type, handle, bool) :
                            el.attachEvent('on' + type, handle);
                } else {
                    for (var i = 0; i < thisLen; i++) {
                        el = this[i];
                        el.addEventListener ? el.addEventListener(type, handle, bool) :
                                el.attachEvent('on' + type, handle);
                    }
                }
            }
        });
    </script>

兼容IE 与Firefox浏览器

        var messageInfo = new Object;
        messageInfo.received = '/HumanResource/Employee/Index';
        messageInfo.infoType = 'technical lead';   
        messageInfo.data = 'technical lead';        
        parent.postMessage(JSON.stringify(messageInfo), window.location);

子窗口向父窗口传递消息

    $(window).addEvent('message', function (ev) {        
        var messageInfoJson = JSON.parse(ev.data);
        var received = messageInfoJson.received;
        if (received != '/Home/Index') {
            console.log('转发消息');
            $("iframe").each(function (i) {
                console.log(ev.data);
                console.log(messageInfoJson);
                window.frames[i].postMessage(ev.data, window.location);
            });
        }
        else {
            alert('哦，Home index 我被点啦。。。' + messageInfo.data);

            console.log('哦，Home index 我被点啦。。。');
            console.log(ev);
        }
    }, false);

接受消息，如不需要自己处理，则转发消息给其他窗口
