Coffeescript未捕獲的TypeError：對象不是函數錯誤

Question

知道為什么@layout = @getLayoutView()行拋出Uncaught TypeError: object is not a function錯誤嗎？ 我似乎無法弄清楚。 與往常一樣，非常感謝您的幫助！

list_controller.js.coffee：

@Demo.module "UsersApp.List", (List, App, Backbone, Marionette, $, _) ->

    List.Controller =

      listUsers: ->
        users = App.request "user:entities"
        @layout = @getLayoutView()
        App.mainRegion.show @layout

      getLayoutView: ->
        new List.Layout

list_view.js.coffee：

@Demo.module "UsersApp.List", (List, App, Backbone, Marionette, $, _) ->

  List.Layout = new Marionette.LayoutView
    template: "users/list/templates/list_layout"

編輯添加路由邏輯

user_app.js.coffee：

@Demo.module "UsersApp", (UsersApp, App, Backbone, Marionette, $, _) ->

    class UsersApp.Router extends Marionette.AppRouter
        appRoutes:
            "users": "listUsers"

    API =
        listUsers: ->
            UsersApp.List.Controller.listUsers()

    App.addInitializer ->
        new UsersApp.Router
            controller: API

app.js.coffee：

@Demo = do (Backbone, Marionette) ->

  App = new Marionette.Application

  App.rootRoute = "users"

  App.addRegions
    headerRegion: "#header-region"
    mainRegion: "#main-region"
    footerRegion: "#footer-region"

  App.addInitializer ->
    App.module("HeaderApp").start()
    App.module("FooterApp").start()

  App.on "start", ->
    if Backbone.history
      Backbone.history.start()
      @navigate(@rootRoute, trigger: true) if @getCurrentRoute() is ""

  App

我猜您應該從“ Marionette.LayoutView”擴展List.Layout，但是這里的代碼段創建了“ Marionette.LayoutView”的實例。 編碼

List.Layout = new Marionette.LayoutView
    template: "users/list/templates/list_layout"

本來應該

class List.Layout extends  Marionette.LayoutView
   template: "users/list/templates/list_layout"
