module Up:sig
..end
Event from client to server.
Up events are quite different from Down events. Because of the asymmetrical nature of web programming and because of the reactive model used, an Up event must be created on the server and wrapped into a callback (or something the client can build a callback with).
Example of use:
let e_up = Eliom_react.Up.create
(Eliom_parameter.ocaml "a" [%json: string])
in
... {{ ignore ( %e_up "A") }} ...
type 'a
t
The type of events that, while being "on the server", are triggered by
clients. On the server such an event is /primitive/ (hence the create
function) whereas it is /effect-full/ on the client.
val to_react : 'a t -> 'a React.E.t
to_react e
injects the up events e
into react events so that it can
be manipulated as a standard event.
val create : ?scope:Eliom_common.scope ->
?name:string ->
('a, [ `WithoutSuffix ],
[ `One of 'a Eliom_parameter.ocaml ] Eliom_parameter.param_name)
Eliom_parameter.params_type -> 'a t
create param
creates an Up event.
If ~name
is present, the coservice used to transmit the event will
always have the same name, even if the server is restarted.
~scope
describes the visibility of the event. By default, it is
`Site
if it is called during initialisation,
`Client_process
otherwise.
