Question

我正在尝试重新填充Memory商店Observable，使用Socket来监控更新。我认为我对Memory/Observable方很好，但我只是没有在Socket方面的某个地方。

初始数据进入商店，我能够观察Socket轮询数据，当我手动编辑数据时，它将获取（用于测试）我可以在控制台中看到它的变化。

require(["dojo/dom", "dojo/dom-construct", "dojo/store/Memory", "dojo/store/Observable", "dojox/socket", "dojo/domReady!"], function (dom, domConstruct, Memory, Observable, Socket) {

// initial data - would come from server
var data = [
    {"type": "foo", "unread": "2"},
    {"type": "bar", "unread": "28"},
    {"type": "baz", "unread": "19"}
];

store = new Memory({data: data});
store = Observable(store);                  

 var abc = '';

// display initial data
store.query().forEach(function(obj){
    abc += '<div class="num">' + obj.unread + '</div>';                         
});

domConstruct.place(abc, dom.byId('nums'));

// Create Socket instance
var socket = new Socket.LongPoll({ 
    url:"/path_to_my/endpoint/", // my endpoint in here returns a json object
    headers: {
        "Accept": "application/json",
        "Content-Type": "application/json"
    }
});             

socket.on("message", function(event){

    var data = event.data;
    console.log(event); // i can observe updated data here

    // this is just copied from some tutorial page
    // i'm not getting how this updates the store....
    store.notify(data.action, {target: data.object, id: data.type});

});

});

See this JSFiddle, for a hopefully reasonable demonstration store.notify位是我被解开的地方......

我还在控制台中注意到Socket每秒轮询5个请求！我可以在这里申请一个油门，或者这是另一个不对劲的迹象吗？

Dojox Socket / Observable Store未更新
