动态值有ng min ng max指令
<input ng-min="vm.diapason.min" ng-max="vm.diapason.max"/>
<select class="form-control" ng-model="vm.diapason"
ng-options="option.label for option in vm.restrictions">
</select>

I am looking for some solution which will update the binding at input control based on selection. Also it should update the validation message.
Looking for some generic and reusable solution so It can be reused across application.

这是你需要的答案，用小提琴
var-app=angular.module（'app'，[]）；
app.controller（'TimeController'，函数（$scope）{
var vm=$scope；
vm.update_values=函数（）{
如果（vm.selected=='hours'）{
vm.min=“1”；
vm.max=“24”；
}else if（vm.selected==='minutes'）{
vm.min=“60”；
vm.max=“6000”；
}否则{
vm.min=“3000”；
vm.max=“10000”；
}
}
});
期望的RPO
请选择
小时
会议记录
秒
请输入介于{min}和{max}之间的值
要求：
如果用户选择：
小时-最小值和最大值应为1到24
分钟-最小值和最大值应为60到6000
秒-最小值和最大值应为3000到10000
我正在寻找一些解决方案，将更新的基础上选择输入控制绑定。它还应该更新验证消息。

我们如何根据选择来更改它们。。你能更新提琴吗？我知道这种方法和其他方法不同，但不知何故，我不能用这种方法使它工作。如果可能的话，你能用你的方法更新一下吗？我把ng值弄错了一点。您可以使用ng选项参与我的方法。将编辑此帖子。请检查plunkr。。就设计而言，你可以相应地修改它。刚才看到了，但Pratik的答案看起来更相关。谢谢你的回答。
