javascript - ng-options 按另一个下拉列表中的值过滤数据

Question

我读过 ng-options filter by value in another dropdown 中的一些例子.

但就我而言，数据位于一个范围内。

我已经尝试过

Make:
<select ng-model="makeng" ng-options="option.id as option.display for option in makes">
    <option ng-disabled="true"  ng-selected="true" value="">Select a make</option>
</select>


Model:
<select ng-model="modelng" ng-options="option.data.name for option in makes | filter:{id:makeng}">
    <option ng-disabled="true"  ng-selected="true" value="">Select a model</option>
</select>

品牌:

<select ng-model="makeng" ng-options="option as option.display for option in makes">
    <option ng-disabled="true"  ng-selected="true" value="">Select a make</option>
</select>

型号:

<select ng-model="modelng" ng-options="option.name for option in makes[makes.indexOf(makeng)].data">
    <option ng-disabled="true"  ng-selected="true" value="">Select a model</option>
</select>
