Module Os_msg

module Os_msg : sig..end

Call this function either from client or server side to display an error message in the page.

The message is displayed in a special box (a "div" with id "os_msg" created automatically in the body of the page).

It is displayed during a short amount of time then disappears. You may change the duration in seconds with the parameter duration (default 2 seconds).

The two levels correspond to different classes that you can personalize by modifying the CSS class "os_err" (added for error messages to the box with ID "os_msg").

If ?onload is true, the message is displayed after the next page is displayed (default false). When called on server side, this is always the case.


val msg : 
  ?level:[ `Err | `Msg ] ->
  ?duration:float -> ?onload:bool -> string -> unit
