我正在遵循官方的角度教程,特別是在第4步,我試圖重新組織我的文件,以便與功能相關的代碼位於單獨的模塊中,如https://docs.angularjs.org/tutorial/step_04AngularJs:TypeError:無法讀取未定義的屬性'控制器'

當我在trip-list/trip-list.module.js中定義一個組件時,它可以工作,但是如果我將定義移動到一個名爲trip-list/trip-list.component.js的單獨文件,它會引發以下誤差在Chrome和IE 9.

angular.js:68 Uncaught Error: [$injector:modulerr] Failed to instantiate module carpoolApp due to: 
Error: [$injector:modulerr] Failed to instantiate module tripList due to: 
TypeError: Cannot read property 'controller' of undefined

  • 的Javascript:app.module.js

var carpoolApp = angular.module('carpoolApp', [ 
 
    'tripList' 
 
]); 
 

 
carpoolApp.component('greetUser', { 
 
       template: 'Hello, {{$ctrl.user}}!', 
 
       controller: function GreetUserController() { 
 
       this.user = 'world'; 
 
       } 
 
      });

  • 使用Javascript - 行程列表/跳閘list.module.js

angular.module('tripList', []);

  • 的Javascript:行程列表/跳閘list.component.js

'use strict'; 
 

 
// this prints a valid object 
 
console.log('tripList module in component', angular.module('tripList')); 
 

 
angular. 
 
    module('tripList'). 
 
    component('tripList', { 
 
    templateUrl: 'trip-list/trip-list.template.html', 
 
    controller: function TripListController() { 
 
     this.trips = [ 
 
      { 
 
       from: 'BNA',

       departureDateAndTime: new Date()

     ]; 
 
    }

// this too prints a valid object 
 
console.log("tripList component registered", angular.module('tripList').component('tripList'));

雖然試圖發送一個Git公關與工作和不工作的改變,我不小心使工作。原來問題是index.html文件沒有正確的EOL(它是dos格式)。您可以在下面的diff中看到^ M的變化。無法計算我浪費了多少小時!

你必須使用角度模塊的二傳手tripList如下

'use strict'; 

// this prints a valid object 
console.log('tripList module in component', angular.module('tripList')); 

angular. 
    //modified the below line 
    module('tripList',[ ]). 
    component('tripList', { 
    templateUrl: 'trip-list/trip-list.template.html', 
    controller: function TripListController() { 
     this.trips = [ 
      { 
       from: 'BNA', 
       to: 'iii', 
       departureDateAndTime: new Date() 
      }, 
      { 
       from: 'iii', 
       to: 'BNA', 
       departureDateAndTime: new Date() 
      } 
     ]; 
    } 
}); 

// this too prints a valid object 
console.log("tripList component registered", angular.module('tripList').component('tripList'));

所述模塊在'跳閘列表被創建/。 trip-list.module.js'文件,這將覆蓋;我懷疑這個問題更多的是爲什麼該模塊沒有被連接到 – Claies

嘗試setter。不起作用。順便說一句,如前所述,相同的片段註冊一個組件,如果我把它放在trip-list.module.js文件中就行了,所以我不確定它是否與代碼本身有關。 – Prasanna

你可以在兩種情況下創建一個plunker! – Aravind
