Backbone和Strophe muc插件:处理传入的事件

标签: backbone.js xmpp strophe

我收到发送到房间的最后一条消息,这些消息也将显示在View中,但是如果Strophe事件处理程序中出现新消息,虽然我看到传输消息节通过线路(连接上的xmlInput),但是不会触发。

可能是什么原因?

连接后,我创建MessageList并注册Strophe处理程序:

 Messages = new MessageList();
 XMPPConnection.addHandler(Messages.onMessageReceived, null, "message", "groupchat");
 XMPPConnection.send($pres({to: "room@conference.server.local/user1"}).c("x", {xmlns: "http://jabber.org/protocol/muc"}));
 window.App = new AppView();

MVC:

// ----------------- Message Model  ----------------   
var Message = Backbone.Model.extend({
  body: "default message",

  initialize: function(body) {
      if (body) {
        this.set({body: body});
      }
  }      
});

// ----------------- Message Collection  ----------------   
var MessageList = Backbone.Collection.extend({
 model: Message,

 initialize: function(body) {       
 },

 onMessageReceived: function(body) {
     var message = new Message($(body).text());
     Messages.add(message);
     return true;
 }           
});

  // ---------------- Message View -------------------  
var MessageView = Backbone.View.extend({
  tagName: "li",

  template: _.template($("#message-template").html()),
  events: {},
  initialize: function() {
      this.model.bind("change", this.render, this);
   //   this.model.bind("remove", this.remove, this);
  },

  render: function() {
      this.$el.html(this.template(this.model.toJSON()));
      return this;    
  }        
});  

// ---------------- App View -------------------  
var AppView = Backbone.View.extend({
    el: $("#myapp"),

    initialize: function() {              
       Messages.bind("add", this.addOneMessage, this);
       this.main = $('#main');
    },

    addOneMessage: function(message) {
        var view = new MessageView({model: message});
        this.$("#message-list").append(view.render().el);
    },
 });

有一些问题,这里有一些提示:

您的Message模型应写为:

var Message = Backbone.Model.extend({
  defaults: {
      body: "default message",
  }
});

如果您传递属性,则无需进行初始化。

您的收藏:

var MessageList = Backbone.Collection.extend({
    model: Message,
});

我还将onMessageReceived放在MessageList:

之外
 var onMessageReceived = function(body) {
     Messages.add({body: $(body).text()});
     return true;
 }           

您的MessageView可以更简单,MUC消息不会更改,只是添加它们:

var MessageView = Backbone.View.extend({
  tagName: "li",

  template: _.template($("#message-template").html()),
  render: function() {
      this.$el.html(this.template(this.model.toJSON()));
      return this;    
  }        
});  

希望这足以让你继续......
