 | `confirm` | `class` | class, always, never, form-data | Should a confirmation prompt be shown to the user before injection happens? Setting this to `form-data` means a prompt will be shown if there are form fields with values that will be replaced with the injected content. A value of `class` means that the pattern will check for the `is-dirty` CSS class on the target element. If the class is there, a confirmation prompt will be shown. | One of the allowable values. |
