Angular 1.5 SharePoint，仅显示选定的部门

Question

我已经从SharePoint列表中创建了一个小型Angular员工电话簿应用程序。该应用程序基于其他教程：

http://ramdotnetdeveloper.blogspot.no/2016/05/sharepoint-2013-filtering-and-sorting.html

虽然scope.sortExpression执行其作业排序，让我们说标题，部门，经理等....我想，因为有子部门能够将这些作为选项添加到下拉列表中，并且只显示这些结果。

因此，如果我选择部门DEP I 1，它只会显示属于该部门的人员，DEP I 2等等是否可以通过某种过滤？

var app = angular.module('ansattApp', ['angularUtils.directives.dirPagination']);           

app.controller('ansattController', function ($scope, $http) { 

    $http({ 
        method: 'GET', 
        url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getByTitle('Telefonkatalog')/items?$top=1000", 
        headers: { "Accept": "application/json;odata=verbose" } 
    }).success(function (data, status, headers, config) { 
        $scope.ansatte = data.d.results;
        $scope.mySortFunction = function(ansatt)  { 
          //Sorting Item  
          if (isNaN(ansatt[$scope.sortExpression]))  
            return ansatt[$scope.sortExpression];  
          return parseInt(ansatt[$scope.sortExpression]);  
        }           
    }).error(function (data, status, headers, config) {}); 
});
