更改滑块的值后,有关滑块值的显示不会更新 这是我的代码: HTML:
<ion-range min="1" max="24" pin= "true" [(ngModel)]="time">
<p range-left>1</p>
<p range-right>24</p>
</ion-range>
<p>{{purchasePrice}}</p>
TS:
time : number
purchasePrice = 10 * this.time
答案 0 :(得分:0)
需要使用(ionChange)并更新该函数中的值
<ion-range min="1" max="24" pin= "true" (ionChange)="updateTime()" [(ngModel)]="time">
<p range-left>1</p>
<p range-right>24</p>
</ion-range>
<p>{{purchasePrice}}</p>
控制器代码:
export class HomePage {
time : number ;
purchasePrice = 0;
constructor(public navCtrl: NavController) {
}
updateTime(){
this.purchasePrice = 10 * this.time;
}
}
