这是我的index.js文件：

var myApp = angular.module('myApp',[]);
myApp.controller('dropdownCtrl', ['$scope','CustomerService', function($scope, CustomerService) {

  $scope.countries = CustomerService.getCountry();

  $scope.getCountryStates = function(){
    $scope.sates = CustomerService.getCountryState($scope.customer.Country);
    $scope.cities =[];
    $scope.mysales = [];
  }

  $scope.getStateCities = function(){
//    debugger;
     $scope.cities = CustomerService.getStateCity($scope.customer.State);
     console.log("Hi");
//     console.log($scope.cities);
  }

  $scope.getStatesSales = function(){
//      debugger;
       $scope.sales = CustomerService.getSalesList($scope.customer.Sales);
//     console.log($scope.sales);

    }


}]);

myApp.factory("CustomerService", ['$filter', function($filter){
 var service = {};


  var countrylist = [
            { "id": 1, "country": "Marketing" },
            { "id": 2, "country": "Sales" },
            { "id": 3, "country": "Customer Service" }
    ];

  var statelist = [
    {"Id":1, "state":"Marketing Team A", "countryId": 1},
    {"Id":3, "state":"Marketing Team B", "countryId": 1},
    {"Id":4, "state":"Territories", "countryId": 2}
  ];

  var citylist = [
    {"Id":5, "city":"Territory A", "stateId": 4},
    {"Id":6, "city":"Territory B", "stateId": 4}
];
   var salesTeamList = [
   {"Id":1, "sales":"Sales Team A", "salesId": 5},
   {"Id":2, "sales":"Sales Team B", "salesId": 5},
   {"Id":3, "sales":"Sales Team A", "salesId": 6},
   {"Id":4, "sales":"Sales Team B", "salesId": 6}

   ];


  service.getCountry = function(){    
    return countrylist;
  };

  service.getCountryState = function(countryId){
    var states = ($filter('filter')(statelist, {countryId: countryId}));
    return states;
  };
  service.getStateCity = function(stateId){    

    var items = ($filter('filter')(citylist, {stateId: stateId}));      
    return items;

  };

  service.getSalesList = function(salesId){

      var items = ($filter('filter')(salesTeamList, {salesId: salesId}));
      return items;
      console.log(items);
   };

  return service;


}]);

你错过了两点：

我在这里将参数更改为var tr = $(this).prev('a').text(); var ya = $(this).closest('.favdelSubFold').find('.sfDel').text(); var pa = $(this).closest('.favdelParentFold').find('.pfDel').text();

$scope.customer.City

在你最后一次下拉菜单中你传递了错误的列表mySales所以我把它改成了ng-repeat中的销售

$scope.getStatesSales = function(){
   $scope.sales = CustomerService.getSalesList($scope.customer.City);
}

See the plunker

如何在4级获得级联下拉？
