ionic 3 alert

To display an alert in Ionic 3, you can use the AlertController module. Here's a code snippet that demonstrates how to create and display an alert:

import { AlertController } from 'ionic-angular';

  selector: 'page-home',
  templateUrl: 'home.html'
export class HomePage {

  constructor(public alertController: AlertController) {}

  presentAlert() {
    const alert = this.alertController.create({
      title: 'Alert',
      subTitle: 'This is an Ionic alert.',
      buttons: ['OK']


In the above example, we import the AlertController module from ionic-angular. Inside the HomePage component, we inject the AlertController into the constructor. The presentAlert method is called to create and display the alert. The create method is used to create the alert with a title, a sub-title, and an OK button. Finally, the present method is called to display the alert on the screen.

Remember to import the necessary modules and include the AlertController in the constructor of your component.
