Angularjs - 错误 : [$injector:unpr]

Question

我正在尝试使用 Angular UI Bootstrap module ，特别是 Modal 插件。 我的应用程序文件夹的结构如下:

• 应用程序
  • 时间表
    • scheda.html
    • schedacontroller.js
  • app.js
• CSS
• ...
• index.html

这是app.js，主应用程序文件:

// created the module GasistaFelice
// also included ngRoute for all our routing needs

angular.module('ngGasistaFelice', [])
.run(function($rootScope) {
    $rootScope.gasID = "10"; //default value
});

angular.module('ngGasistaFelice', ['ui.bootstrap']);

var GasistaFelice = angular.module('ngGasistaFelice', ['ngRoute']);

GasistaFelice.config(['$routeProvider',function($routeProvider) {
            $routeProvider
// route for the home page
            .when('/', {
                templateUrl : 'app/ordinare/ordinare.html',
                controller  : 'orderController'
            })

            // route for the paniere page
            .when('/:id/gasmember/:id/basket', {
                templateUrl : 'app/paniere/paniere.html',
                controller  : 'paniereController'
            })

            // route for the scheda page
            .when('/:id/profile', {
                templateUrl : 'app/scheda/scheda.html',
                controller  : 'schedaController'
            })

            // route for the conto page
            .when('/:id/gasmember/:id/cash', {
                templateUrl : 'app/conto/conto.html',
                controller  : 'contoController'
            })
            .otherwise({
                    redirectTo: '/'
                });
    }]);

异常(exception)......

这是我想在其中放置 Modal 插件的页面的 Controller :

var app = angular.module('ngGasistaFelice', ['ui.bootstrap']);
app.controller('schedaController', function ($scope, $routeParams, $modal, $log, $http) {
        var id = $routeParams.id;
        // --- URL finale --- 
        //var url = 'http://localhost:8000/gasistafelice/api/v1/person/id/?format=json';
        //URL di prova

        $scope.items = ['item1', 'item2', 'item3'];

          $scope.open = function (size) {

            var modalInstance = $modal.open({
              templateUrl: 'myModalContent.html',
              controller: ModalInstanceCtrl,
              size: size,
              resolve: {
                items: function () {
                  return $scope.items;
                }
              }
            });

            modalInstance.result.then(function (selectedItem) {
              $scope.selected = selectedItem;
            }, function () {
              $log.info('Modal dismissed at: ' + new Date());
            });
          };

当我加载包含 schedaController 的页面时，我不断收到此错误:

您使用不同的所需模块多次定义 angular.module('ngGasistaFelice', []) (在 module 函数的第二个参数内):

angular.module('ngGasistaFelice', [])
angular.module('ngGasistaFelice', ['ui.bootstrap']);
var GasistaFelice = angular.module('ngGasistaFelice', ['ngRoute']);
var app = angular.module('ngGasistaFelice', ['ui.bootstrap']);

...具体来说，最后一个是您尝试使用 ngRoute 的那个，但您甚至还没有在那里注入(inject)它。

更好的解决方案是定义一次，例如:

var GasistaFelice = angular.module('ngGasistaFelice', [
    'ui.bootstrap',
    'ngRoute'
]);

然后你就可以做你想做的事情了:

GasistaFelice.controller(...);

或者，如果您在另一个文件(或作用域)中需要它并且 GasistaFelice 尚未定义，您可以通过调用 angular.module 来获取它 不使用传递所需的依赖项，例如:

var app = angular.module('ngGaistaFelice');
app.controller(...);
