[置顶] ionic 2 实践小结

1.ionic2里ion-select便签更改值举例，

<ion-select [(ngModel)]="address.privince" (ionChange)="changeProvince(address.privince)">
      <ion-option *ngFor="let item of provinceList" [value]='item.id'>{{item.name}}</ion-option>
    </ion-select>

注意使用

(ionChange)

2.ModalController 传值

let modal = this.modalCtrl.create(BuyPage,{comm:this.comm});
    modal.present();

ModalController传值与NavController一样，只要在父page传入，modal page获取，获取方法也相同

 constructor(private navParam:NavParams,
              public viewCtrl: ViewController) {
    this.comm=navParam.get("comm");
    console.log(this.comm);
  }
