downloads.erase()

La fonction erase() de l'API downloads efface la correspondance DownloadItems de l'historique de téléchargement du navigateur sans supprimer les fichiers téléchargés du disque.

Pour supprimer les fichiers du disque, vous devez utiliser downloads.removeFile().

C'est une fonction asynchrone qui renvoie une Promise.

Remarque : Si vous souhaitez supprimer un fichier téléchargé du disque et l'effacer de l'historique, vous devez appeler downloads.removeFile() before you call erase(). Si vous l'essayez dans l'autre sens, vous obtiendrez une erreur lors de l'appel de downloads.removeFile(), car il n'existe plus selon le navigateur.
