        </tr>

        <tr ng-repeat="cust in customers | filter:customerFilter | orderBy:sortBy:reverse">
            <td>{{ cust.name }}</td>
            <td>{{ cust.city }}</td>

这是我的CustomerController.js

function CustomersController($scope){
    $scope.sortBy = 'name';
    $scope.reverse = false;
    $scope.customers = [
        {
            joined: "2000-12-24", 
            name: "Charles", 
            city: "Fairfax", 
            orderTotal: "12414432.45"
        },
        {
            joined: "2000-09-12", 
            name: "Jack", 
            city: "Altamonte Springs", 
            orderTotal: "5.9943"
        },
        {
            joined: "2000-01-25", 
            name: "Bill", 
            city: "Waldorf", 
            orderTotal: "100"
        }
    ],
    $scope.doSort = function(propName){
        $scope.sortBy = propName;
        $scope.reverse = !$scope.reverse;
    };
}

请将此行添加到您的CustomerController.js

 angular.module("app", []).controller("CustomersController", CustomersController);

＆＃13;

angular.module("app", []).controller("CustomersController", CustomersController);



function CustomersController($scope) {
  $scope.sortBy = 'name';
  $scope.reverse = false;
  $scope.customers = [{
      joined: "2000-12-24",
      name: "Charles",
      city: "Fairfax",
      orderTotal: "12414432.45"
    }, {
      joined: "2000-09-12",
      name: "Jack",
      city: "Altamonte Springs",
      orderTotal: "5.9943"
    }, {
      joined: "2000-01-25",
      name: "Bill",
      city: "Waldorf",
      orderTotal: "100"
    }],
    $scope.doSort = function(propName) {
      $scope.sortBy = propName;
      $scope.reverse = !$scope.reverse;
    };
}

控制器，服务，指令和过滤器都应包含在Angular模块中。为页面定义控制器有两种主要方法。使用routing或仅使用ngController。您正在尝试使用ngController但尚未定义模块。

在您的HTML中，您可以使用ngApp定义主模块。

所以你的HTML标签可以读取：

<html lang="en" data-ng-app="myApp">

然后，您可以使用以下内容将现有CustomersController分配给此模块：

angular.module('myApp', [])
  .controller('CustomersController', CustomersController);

或者，另一种方法是简单地在控制器块中定义控制器逻辑：

angular.module('myApp', [])
  .controller(function() {
    // your logic here
  });

控制器未找到
