javascript - 类型错误 : Cannot read property 'index' of undefined

Question

TypeError: Cannot read property 'index' of undefined

var crud = angular.module('Crud', ['ngRoute']);

crud.config(['$routeProvider', function($routeProvider){
    $routeProvider.when('/edit/:index', {
        templateUrl: 'js/views/edit.html',
        controller: 'EditCtrl'
    }).when('/',{
        templateUrl: 'js/views/list.html'
    })
}]);

crud.controller('EditCtrl',['$scope', function(scope,$routeParams){
    scope.name = scope.names[$routeParams.index];
}]);

为什么我的索引未定义。我的网址似乎没问题， http://localhost:63342/Angular-CRUD/#/edit/2 看来 id 从 View 中正确传递，但为什么我 获取索引 在我的 Controller 中未定义。

您尚未在依赖项中传递 $routeParams

                                     //here
crud.controller('EditCtrl',['$scope','$routeParams', function(scope,$routeParams){
    scope.name = scope.names[$routeParams.index];
}]);
