Notification methods

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

  • ons.notification.alert(message, options)
  • ons.notification.confirm(message, options)
  • ons.notification.prompt(message, options)
  • 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.
  });
