Question

TodoMVC.module "TodoList", (TodoList, App, Backbone, Marionette, $, _) ->

  # TodoList Router
  # ---------------
  #
  # Handle routes to show the active vs complete todo items
  TodoList.Router = Marionette.AppRouter.extend
    appRoutes: "*filter": "filterItems"

  # TodoList Controller (Mediator)
  # ------------------------------
  #
  # Control the workflow and logic that exists at the application
  # level, above the implementation detail of views and models
  TodoList.Controller = ->
    @todoList = new App.Todos.TodoList()

  _.extend TodoList.Controller::,

    # Start the app by showing the appropriate views
    # and fetching the list of todo items, if there are any
    start: ->
      @showHeader @todoList
      @showFooter @todoList
      @showTodoList @todoList
      App.bindTo @todoList, "reset add remove", @toggleFooter, this
      @todoList.fetch()

    showHeader: (todoList) ->
      header = new App.Layout.Header(collection: todoList)
      App.header.show header

    showFooter: (todoList) ->
      footer = new App.Layout.Footer(collection: todoList)
      App.footer.show footer

    showTodoList: (todoList) ->
      App.main.show new TodoList.Views.ListView(collection: todoList)

    toggleFooter: ->
      App.footer.$el.toggle @todoList.length

    # Set the filter to show complete or all items
    filterItems: (filter) ->
      App.vent.trigger "todoList:filter", filter.trim() or ""


  # TodoList Initializer
  # --------------------
  #
  # Get the TodoList up and running by initializing the mediator
  # when the the application is started, pulling in all of the
  # existing Todo items and displaying them.
  TodoList.addInitializer ->
    controller = new TodoList.Controller()
    new TodoList.Router(controller: controller)
    controller.start()

未捕获NoMethodError：在控制器上找不到方法'filterItems'

我已经使用TodoMVC example for Marionette，并使用js2coffee将其转换为CoffeeScript，并且我正在使用requirejs。我不确定为什么会这样，因为我没有添加真正的自定义代码。如果我可以提供任何其他信息，请告知我们。

我也有这个错误。

问题出在以下代码中：

TodoList.Controller = ->
    @todoList = new App.Todos.TodoList()

一旦转换为JS，它将在第二行前面添加return。对我来说，添加true作为下一行解决了问题。

TodoList.Controller = ->
    @todoList = new App.Todos.TodoList()
    true
