javascript - angular Ng-options 错误？

Question

我正在尝试使用基于 ng-option 的下拉列表。我的代码目前看起来像这样:

<select
     ng-options="choice.id as choice.singular in model.quanityChoices"
     ng-model="med.id"
     <option value=""></option>
</select>

它基于的模型数据如下所示:

[
 {id: 1, singular: 'word'},
 {id: 2, singular: 'word2'}
]

目前我的目标是有一个下拉列表，用户将在其中看到选项“word”和“words”，但应用的值是 ID。

目前我的代码有如下错误:

Error: [ngOptions:iexp] Expected expression in form of '_select_ (as _label_)? for (_key_,)?_value_ in _collection_' but got 'choice.id as choice.singular in model.quantityFormChoices'. Element: <select...

您没有正确构建它，请查看错误，因为它为您提供了有关如何操作的详细信息:

<select
     ng-options="choice.id as choice.singular for choice in model.quanityChoices"
     ng-model="med.id"
     <option value=""></option>
</select>
