Adding class to sweet alert

问题

I am trying to add an extra class for my modal so I can select it from LESS and turn it's background to transparent. But customClass is not working. Is there any other way to do it. BTW I have already changed a lot with default classes so I need to do this for just one modal, can not effect the global swal.

   swal({
      title: success,
      showConfirmButton: false,
      html: true,
      customClass: ".swal-back"
   });

回答1:

The customClass option has been removed. You need to use className now instead. The period before the class name is not necessary.

swal({
  title: success,
  showConfirmButton: false,
  html: true,
  className: "swal-back"
});
