我有一个“业务”收集，我通过几个意见。
当我运行这个.business.fetch（）时，返回的模型是完全相同的，但是事件'add'和'remove'被触发了，因为集合认为返回的模型是新的，所以它删除了'old'并添加了'new'模型。我能看到的模型之间的唯一区别是cid。
为什么取物者认为集合已经改变了？即使它没有改变？
这是我的代码：

router.js
var Router = Backbone.Router.extend({
routes: {
    "home": "home",
}
initialize: function() {
  this.business = new Business();
  this.business.fetch();
},
home: function() {
  var homepageView = new HomePageView({business: this.business});
},

。

HomePageView.js
var HomePageView = Backbone.View.extend({
initialize: function (options) {
  this.business = options.business;
  this.listenTo(this.business, "add",    this.onBusinessAdd);
  this.listenTo(this.business, "remove", this.onBusinessRemove);
  this.listenTo(this.business, "change", this.onBusinessRemove);
  this.business.fetch();
},
onBusinessAdd: function(model) {
  console.log(model);
},
onBusinessRemove() & onBusinessChange() are the same as onBusinessAdd()

。

collection/business.js
var BusinessCollection = BaseCollection.extend({
initialize : function() {
  this.urlRoot = this.path + 'business/me';
  this.url = this.path + 'business/me';
  this.model = BusinessModel;
}

。
我有一个名为items的不同集合，它可以很好地提取。但由于某种原因，当我运行business.fetch（）时，在第一次提取时，它会添加两个businesscid 19 & 20，然后在第二次提取时，它会删除cid 19 & 20并添加cid 23 & 24，尽管它们是相同的
我在控制台中看到以下内容：

first fetch: (router.js)
"onBusinessAdd"
n {cid: "c19", attributes: Object, collection: n, _changing: false, _previousAttributes: Object…}
n {cid: "c20", attributes: Object, collection: n, _changing: false, _previousAttributes: Object…}

second fetch: (homepageview.js)
"onBusinessRemove"
n {cid: "c19", attributes: Object, collection: n, _changing: false, _previousAttributes: Object…}
n {cid: "c20", attributes: Object, collection: n, _changing: false, _previousAttributes: Object…}
"onBusinessAdd"
n {cid: "c23", attributes: Object, collection: n, _changing: false, _previousAttributes: Object…}
n {cid: "c24", attributes: Object, collection: n, _changing: false, _previousAttributes: Object…}

.属性“c19”==“c23”和“c20”==“c24”

Object {_id: "567b6997a58029fc087b1716", hasLogo: false, approved: false, postcode: "2131", suburb: "1231321"…}

这给我带来了一个问题，因为我的navbar render（）在每次onBusinessAdd函数被调用时都会被调用，并且由于某种原因，jasny-bootstrap navbar会在每个render（）上出错并克隆自己，这会导致延迟。（我必须在修复这个问题后再研究这个问题）
