How to update a field in Ionic automatically?

Question

I’m having trouble generating coordinates on Ionic using geolocation. It only works if you press several times the button that calls the function, until the coordinates appear. So, I wanted to know how to make a part of the code call the function automatically, without me updating "manually"?

<ion-item>
          <ion-input type="text" [(ngModel)]="cad.longitude" value="{{long}}" (click)="local()" readonly>
          </ion-input>
</ion-item>

Answer 1

You can create a function in the file . ts that calls the function local() x in x minutes. In the example below, I call every 3 minutes. This parameter you set in the setInterval.

constructor() {


  platform.ready().then(() => {      

  setInterval(() => {
    this.local(); //sua função
  },180000);  //tempo em milisegundos


});

}

Answer 2

var geolocationInterval;

ionViewDidLoad() {
    geolocationInterval = setInterval(() => this.local(), 5000);
}

ionViewWillLeave() {
    clearInterval(geolocationInterval);
}
