Question

我在ng-options filter by value in another dropdown中读到了一些例子。

但在我的情况下，数据在一个范围内。

我试过

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>

根本不需要过滤器：

请：

<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>

ng-options按另一个下拉列表中的值过滤一个数据
