角度Ng选项错误？(angular Ng-options error?)

我正在尝试使用基于ng-option的下拉菜单。 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>

基于此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，用户将看到选项'word'和'words'，但应用的值是ID。

目前我的代码有以下错误：

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...

I am trying to use an ng-option based drop down. My code currently looks like this:

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

The model data this is based off looks like this:

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

Currently my goal is to have a dropdown where the user will see the options 'word' and 'words' but the value that gets applied is the ID.

Currently my code has the following error:

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...

最满意答案

您没有正确构造它，查看错误，因为它为您提供了有关如何执行此操作的详细信息：

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

You didn't structure it correctly, look at the error as it gives you the details on how to do it:

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