<ion-select [(ngModel)]="city"  (ngModelChange)="getRrgionList()" okText="確定" cancelText="取消"> 
      <ion-option selected="">請選擇城市</ion-option>
      <ion-option *ngFor="let vo of cityList" value="{{vo.id}}">{{vo.name}}</ion-option> 
</ion-select> 


<button  type="submit"  class="save-btn" (click)="getSubmit()" tappable>確定</button>


getSubmit(){
    console.log(this.city);
}

想獲取name; 每次選中之后打印出來的都是id,因為頁面上傳的id是通過省id來查詢市列表
