Examples

The most basic message:

swal('Hello world!');

A message signaling an error:

swal('Oops...', 'Something went wrong!', 'error');

Handling the result of SweetAlert2 modal:

swal({
  title: 'Are you sure?',
  text: 'You will not be able to recover this imaginary file!',
  type: 'warning',
  showCancelButton: true,
  confirmButtonText: 'Yes, delete it!',
  cancelButtonText: 'No, keep it',
}).then(function() {
  swal(
    'Deleted!',
    'Your imaginary file has been deleted.',
    'success'
  );
}, function(dismiss) {
  // dismiss can be 'overlay', 'cancel', 'close', 'esc', 'timer'
  if (dismiss === 'cancel') {
    swal(
      'Cancelled',
      'Your imaginary file is safe :)',
      'error'
    );
  }
});

Handling Dismissals

When an alert is dismissed by the user, the Promise returned by swal() will reject with a string documenting the reason it was dismissed:

String	Description	Related configuration
"overlay"	The user clicked the overlay.	allowOutsideClick
"cancel"	The user clicked the cancel button.	showCancelButton
"close"	The user clicked the close button.	showCloseButton
"esc"	The user pressed the Esc key.	allowEscapeKey
"timer"	The timer ran out, and the alert closed automatically.	timer

If rejections are not handled, it will be logged as an error. To avoid this, add a rejection handler to the Promise. Alternatively, SweetAlert2 provides the .done() method as a quick way to simply suppress the errors:

swal('...')
  .done();
