$ons.notification

Utility methods to create different kinds of notifications. There are three methods available:

  • ons.notification.confirm()
  • ons.notification.prompt()
  • ons.notification.toast() It will automatically display a Material Design dialog on Android devices.

Tutorial

Notification methods

The $ons.notification object contains some useful methods to easily show alerts, confirmation dialogs and prompts:

1.

$ons.notification.alert(message, options)

2.

$ons.notification.confirm(message, options)

3.

$ons.notification.prompt(message, options)

4.

$ons.notification.toast(message, options)

They all return a Promise object that can be used to handle the input from the user.

$ons.notification.confirm('Are you ready?')
  .then((response) => {
    // Handle response.
  });

Notifications can also be created using VOnsDialog, VOnsAlertDialog and VOnsToast instead of $ons.notification.
