Javascript 未捕获类型错误：MyView不是函数

我创建了my-view.js文件，如下所示：

(function (Backbone) {
  var MyView = Backbone.View.extend({
    className: 'card my-card',
    template: $('#my-template').html(),
    initialize: function(options) {
      this.render()
    },
    render: function() {
      var html = _.template(this.template);
      this.$el.html(html);
      return this;
    }
  });

  app.modules.MyView = MyView;
}(window.Backbone);

(function (Backbone) {
  var MyDayCardView = app.modules.MyView,  
  var AppController = Backbone.View.extend({
    initialize: function(){  
      var self = this;
    },
    appStart: function() {
      this.MyDayCardView = new MyDayCardView();
      self.$el.append(this.MyDayCardView.el);
    }
  });

  app.controllers.AppController = new AppController();    
}(window.Backbone);

在app-controller.js中，我写了如下内容：

(function (Backbone) {
  var MyView = Backbone.View.extend({
    className: 'card my-card',
    template: $('#my-template').html(),
    initialize: function(options) {
      this.render()
    },
    render: function() {
      var html = _.template(this.template);
      this.$el.html(html);
      return this;
    }
  });

  app.modules.MyView = MyView;
}(window.Backbone);

(function (Backbone) {
  var MyDayCardView = app.modules.MyView,  
  var AppController = Backbone.View.extend({
    initialize: function(){  
      var self = this;
    },
    appStart: function() {
      this.MyDayCardView = new MyDayCardView();
      self.$el.append(this.MyDayCardView.el);
    }
  });

  app.controllers.AppController = new AppController();    
}(window.Backbone);

然后我得到了一个错误：

未捕获类型错误：MyView不是函数 Backbone.View.extend.appStart@app-controller.js：

我哪里做错了？

您有一些语法问题，请参阅下面的代码

var app={};
app.modules={};
app.controllers={};
// Add your javascript here
(function (Backbone) {
  var MyView = Backbone.View.extend({
    className: 'card my-card',
    template: $('#my-template').html(),
    initialize: function(options) {
      this.render()
    },
    render: function() {
      var html = _.template(this.template);
      this.$el.html(html);
      return this;
    }
  });

  app.modules.MyView = MyView;
}(window.Backbone));

(function (Backbone) {
  var MyDayCardView = app.modules.MyView,  
   AppController = Backbone.View.extend({
    initialize: function(){  
      var self = this;
    },
    appStart: function() {
      this.MyDayCardView = new MyDayCardView();
      self.$el.append(this.MyDayCardView.el);
    }
  });

  app.controllers.AppController = new AppController();    
}(window.Backbone));

此代码不可能在您的浏览器中运行，错误百出。您确定my-view.js在controller.js之前执行吗？此代码不可能在您的浏览器中运行，错误百出。您确定my-view.js在controller.js之前执行吗？
