ionic 3 - show confirm alert after click on ion-toggle

Issue

I'm trying to use click event on ion-toggle and is not working.

Html:

  <ion-item>
     <ion-label class="labelToggle">Ativo:</ion-label>
     <ion-toggle (click)="mudarStatusProcesso()" [(ngModel)]="ProcAtivo"></ion-toggle>
  </ion-item>

The mudarStatusProcesso() creates an AlertController with 'ok' and 'cancel' options, this action needs happen before ion-toggle updating. I believe that i should use other prop instead "(click)", can anyone help me?

Solution

You can use (ngModelChange),

<ion-item>
   <ion-label class="labelToggle">Ativo:</ion-label>
   <ion-toggle [(ngModel)]="ProcActivo" (ngModelChange)="mudarStatusProcesso()"></ion-toggle>
</ion-item>

In your .ts,

ProcActivo: boolean = false; // default value

mudarStatusProcesso(){

    let alert = this.alertCtrl.create({
      title: null,
      message: "Confirm?",
      buttons: [{
        text: 'Cancel',
        role: 'cancel',
        handler: () => {
          if(this.ProcActivo==false){
            this.ProcActivo=true;
          }else{
            this.ProcActivo=false;
          }
        }
      },
      {
        text: 'Okay',
        handler: () => {

        }
      }
    ]
  });
  alert.present();

  }
