class PostMessage

Defined at line 870 of file fidling/gen/sdk/fidl/fuchsia.web/fuchsia.web/cpp/fidl/fuchsia.web/cpp/markers.h

Posts a message to the frame's onMessage handler.

`target_origin` restricts message delivery to the specified origin. If `target_origin` is

`"*"`, then the message will be sent to the document regardless of its origin.

See the

[HTML spec](https://html.spec.whatwg.org/multipage/web-messaging.html#posting-messages)

section 9.4.3 for more details on how the target origin policy is applied.

If an error occurred, the [`FrameError`] will be set to one of these values:

- `INTERNAL_ERROR`: The WebEngine failed to create a message pipe.

- `BUFFER_NOT_UTF8`: The script in `message`'s `data` property is not UTF-8 encoded.

- `INVALID_ORIGIN`: `origins` is an empty vector.

- `NO_DATA_IN_MESSAGE`: The `data` property is missing in `message`.
