在角度/离子2中获取选定的ngModel值？

<ion-input [(ngModel)]="myValue" #myModel></ion-input>
<button (click)="getValue()">获取值</button>

import { Component, ViewChild } from '@angular/core';
import { IonInput } from '@ionic/angular';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent {
  @ViewChild('myModel') myModel: IonInput;
  myValue: string;

  getValue() {
    console.log(this.myModel.value);
  }
}
