javascript - AngularJS - ng-options 未填充对象列表

Question

我正在尝试填充 AngularJS 中的组合框。下面是 Controller 代码。

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

app.controller('roadmap', function($rootScope, $scope, $http, $q, leFactory) {
    $rootScope.activityInfoList=[];

    $rootScope.brand_strategy_list=[];
    $rootScope.brand_strategy_csf=[];
    $rootScope.brand_strategy_initiatives=[];

    leFactory.getActivityPopupInfo().then(function(activityList) {
        $rootScope.activityInfoList=angular.copy(activityList);
        console.log($rootScope.activityInfoList);

        $rootScope.brand_strategy_list=$rootScope.activityInfoList.listBrandStrategy;

        console.log($rootScope.brand_strategy_list);

        console.log('editActivityPopup service accepted-> ');
    }, function(error) {
        console.log('editActivityPopup service rejected-> ', error);
    });

    $rootScope.items = [{
      id: 1,
      label: 'aLabel',
      subItem: { name: 'aSubItem' }
    }, {
      id: 2,
      label: 'bLabel',
      subItem: { name: 'bSubItem' }
    }];



});

在 HTML 部分，我尝试填充 $rootScope.brand_strategy_list，如下所示。

    <select ng-model="activityInfoList.brandStrategy" class="selectpicker" data-style="btn-inverse" style="display: none;"  ng-options="item.strategyName as item.strategyName for item in brand_strategy_list">
        <option> Select </option>
     </select>

$rootScope.brand_strategy_list 未填充。但是当我尝试填充 $rootScope.items 时，它正在被填充。我制作了 console.log($rootScope.brand_strategy_list) 并显示了完整的列表。

不知道我犯了什么错误？请帮我解决这个问题。提前致谢。

试试这个

ng-options="item.strategyName as item.strategyName for item in $root.brand_strategy_list
