AngularJS - ng-options 不工作

AngularJS - ng-options isn't working

我有以下 data.types:

types: Object
  4: "x"
  5: "c"
  9: "y"

我正在尝试这个:

<select ng-options="key as value for (key, value) in data.types">

但无法填充 select 输入。如何使用 ng-options 而不是 ng-repeat

<select ng-model="yourModel" ng-options="key as value for (key, value) in data.types">

应该可以

您在 select 标签中错过了 ng-model

<select ng-model="yourNgModel" ng-options="key as value for (key, value) in data.types">
</select>
