Angular 2 ngModelChange选项,获取特定属性

我有一个下拉选择形式在角度2.

目前：当我选择一个选项时,选项名称将作为$event传入我的onChange函数

想要：当我选择一个选项时,我想将workout.id传递到我的onChange函数中.

我该如何实现呢？

<select class="form-control" [ngModel]="selectedWorkout" (ngModelChange)="onChange($event)">
    <option *ngFor="#workout of workouts">{{workout.name}}</option>
</select>

调节器

onChange(value){
  alert(JSON.stringify(value));
}

<select class="form-control" [ngModel]="selectedWorkout" (ngModelChange)="onChange($event)">
    <option *ngFor="#workout of workouts" [value]="workout.id">{{workout.name}}</option>
</select>

要么

<select class="form-control" [(ngModel)]="selectedWorkout" (change)="onChange($event.target.value)">
    <option *ngFor="#workout of workouts" [value]="workout.id" >{{workout.name}}</option>
</select>
