Prevent multiple Ionic Alerts from stacking up

Question

How can I detect if ionic 2 alert ui component instance is already open in order not to present another alert ?

Answer 1

My solution worked, i had to put a boolean and set it true after a cancel event and set it false when an alert is presented

if (this.network_alert) {
      let alert = await this.alertController.create({
        header: "No Network",
        message:
          "Please check your internet connection",
        buttons: [{
          text: "Dismiss",
          role: 'cancel',
          handler: () => {
            console.log('Cancel clicked');
            this.network_alert = true
          }
        }],

      });
      await alert.present();
      this.network_alert = false
    }
  }
