可以在这里看到
例如，当我选择 3 时，输出变为
欢迎消息:caner aydin [object Object]
我在这里得到值
<select ng-model="caner.age"
ng-options=" person.age for person in peole" >
在 Controller 中
$scope.peole = [{
age: 1,
name: 'Bob'
}, {
age: 2,
name: 'Alice'
}, {
age: 3,
name: 'Steve'
}];
它应该给出 3 ，而不是 object object 输出。我输入 caner.age 来给出输出。
最佳答案
将下拉标记更改为以下内容。
<select ng-model="caner.age"
ng-options=" person.age as person.age for person in peole" >
</select>
