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(isConfirm) {
  if (isConfirm === true) {
    swal(
      'Deleted!',
      'Your imaginary file has been deleted.',
      'success'
    );

  } else if (isConfirm === false) {
    swal(
      'Cancelled',
      'Your imaginary file is safe :)',
      'error'
    );

  } else {
    // Esc, close button or outside click
    // isConfirm is undefined
  }
});

swal(...) returns a Promise Object, isConfirm parameter in Promise method then will be:

• true for "Confirm"-button
• false for "Cancel"-button
• undefined for Esc press, close button or outside click
