AngularJS - ng-options不起作用

Question

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">

但是无法填充选择输入。如何使用ng-options代替ng-repeat。

Answer 1

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

应该工作

Answer 2

您错过ng-model选择标记。

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