angularjs - 关联的 Angular 用户界面选择

Question

我正在尝试进行分组 ui-select，实际上每个 ui-select 选项都取决于前一个。例如，我在第一个 UI-select 中有一个级别列表，然后根据第一个 ui-select 选择的项目，将在第二个 ui-select 上显示一个位置编号列表。那可能吗？这是我的代码，但我还不能实现它:(

<div class="SumoSelect sumo_somename" tabindex="0" style="width:80%">
        <ui-select search-enabled=false ng-model="levelNumber.selected"
                        theme="bootstrap" append-to-body="true" on-select="getListPlacePerLevel(levelNumber.selected)">
                    <ui-select-match placeholder="">{{$select.selected.levelNumber}}</ui-select-match>
                    <ui-select-choices repeat="item in levels">
                    <span ng-bind="item.levelNumber"></span> </ui-select-choices> </ui-select>
    </div>
    <div class="SumoSelect sumo_somename" tabindex="0" style="width:80%; margin-top:20px;">
        <ui-select search-enabled=false ng-model="item.selected"
                        theme="bootstrap" append-to-body="true">
                    <ui-select-match placeholder="">{{$select.selected.item}}</ui-select-match>
                    <ui-select-choices repeat="item in levelNumber.selected.listPlaceNumber">
                    <span ng-bind="item"></span> </ui-select-choices> </ui-select>
    </div>

我的Json数据如下

[{"levelNumber":1,"listPlaceNumber":[1,2,3,4,6]},{"levelNumber":2,"listPlaceNumber":[2,4,6,7]},{"levelNumber":3,"listPlaceNumber":[11,12,13,14,16]}]
