Ionic Provides various popup alerts that can be used easily in any application. There are – Basic Alerts, Prompt Alerts, Confirmation Alerts, Radio Alerts and Checkbox Alerts available in Ionic.
Here in this tutorial, we are going to explain how to create ionic popup alert step by step with example and demo.You can also use our online editor to edit and run the code online.

Note : These popups are supported in Angular Version > 2.x.

Ionic Popup | Alert | Prompt | Confirmation Alert | Example

Popup is dialog box that is used to show important message or information to User or It can can used
to get some input from user for example – Prompt box to enter wi-fi username/password.

Now let us understand popup alert with example & demo –

1. Basic Alerts
2. Prompt Alerts
3. Confirmation Alerts
4. Radio Alerts
5. Checkbox Alerts

AlertController is required to create alerts so don’t forget to import this controller.

Basic Alerts

1. HTML Part – It contains the view part of basic alert.
2. Script Part – This contains typescript code for the basic Alert.

Html Part : demo.html

So now add the following code to create button layout-

Ionic Popup Example: Html Part

<ion-content padding="">
  <h2>Alert</h2>
  <button ion-button="" block="">
    Show Alert
  </button>
</ion-content>

Html contains the Layout part of the page, a button “Show Alert” is created to call function showAlert() which opens a basic alert, this function is defined in JavaScript Typescript – demo.ts file.

Script Part : demo.ts

It contains script resources to create Alert Box, showAlert() function is defined in this file which is triggered on Button click to open the Alert Box.

Ionic Popup Alerts Example: Script Part

import { Component } from '@angular/core';
import { AlertController } from 'ionic-angular';

@Component({
  templateUrl: 'demo.html'
})
export class DemoPage {
  constructor(public atrCtrl: AlertController) {

  }
 showAlert() {
    let alert = this.atrCtrl.create({
      title: 'Basic Alert!',
      subTitle: 'You do not have enough amount in your wallet, Please add more Money!',
      buttons: ['OK']
    });
    alert.present();
  }
    
 
}

Import AlertsController, add in constructor and call create() method with parameters.
So we can see clearly only following things are required to create alerts.
