二、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 clicked 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, you can use .catch(swal.noop) as a quick way to simply suppress the errors:
swal(...) .catch(swal.noop)
