melange 4.0.0-51 · OCaml Package

Bindings to functions in the JS global namespace

Contains functions available in the global scope (window in a browser context)

type intervalId

Identify an interval started by setInterval

type timeoutId

Identify timeout started by setTimeout

val clearInterval : intervalId -> unit

Clear an interval started by setInterval

(* API for a somewhat aggressive snoozing alarm clock *)

let interval = ref Js.Nullable.null

let remind () =
  Js.log "Wake Up!";
  IO.punchSleepyGuy ()

let snooze mins =
  interval := Js.Nullable.return (Js.Global.setInterval remind (mins * 60 * 1000))

let cancel () =
  Js.Nullable.iter !interval (fun[\@u] intervalId -> Js.Global.clearInterval intervalId)

see https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/clearInterval
MDN

val clearTimeout : timeoutId -> unit

Clear a timeout started by setTimeout

(* A simple model of a code monkey's brain *)

let timer = ref Js.Nullable.null

let work () =
  IO.closeHackerNewsTab ()

let procrastinate mins =
  Js.Nullable.iter !timer (fun[\@u] timer -> Js.Global.clearTimeout timer);
  timer := Js.Nullable.return (Js.Global.setTimeout work (mins * 60 * 1000))

MDN

val setInterval : f:(unit -> unit) -> int -> intervalId

Repeatedly executes a callback with a specified interval (in milliseconds) between calls

Return an intervalId that can be passed to clearInterval to cancel the timeout

see https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setInterval

MDN

(* Will count up and print the count to the console every second *)

let count = ref 0

let tick () =
  count := !count + 1; Js.log (string_of_int !count)

let _ =
  Js.Global.setInterval tick 1000

val setIntervalFloat : f:(unit -> unit) -> float -> intervalId

Repeatedly executes a callback with a specified interval (in milliseconds) between calls

Return an intervalId that can be passed to clearInterval to cancel the timeout

see https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setInterval

MDN

(* Will count up and print the count to the console every second *)

let count = ref 0

let tick () =
  count := !count + 1; Js.log (string_of_int !count)

let _ =
  Js.Global.setIntervalFloat tick 1000.0

val setTimeout : f:(unit -> unit) -> int -> timeoutId

Execute a callback after a specified delay (in milliseconds)

returns a timeoutId that can be passed to clearTimeout to cancel the timeout

see https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setTimeout

MDN

(* Prints "Timed out!" in the console after one second *)

let message = "Timed out!"

let _ =
  Js.Global.setTimeout (fun () -> Js.log message) 1000

val setTimeoutFloat : f:(unit -> unit) -> float -> timeoutId

Execute a callback after a specified delay (in milliseconds)

returns a timeoutId that can be passed to clearTimeout to cancel the timeout

see https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setTimeout

MDN

(* Prints "Timed out!" in the console after one second *)

let message = "Timed out!"

let _ =
  Js.Global.setTimeoutFloat (fun () -> Js.log message) 1000.0

val decodeURI : string -> string

Decodes a URL-enmcoded string produced by encodeURI

MDN

val encodeURIComponent : string -> string

URL-encodes a string, including characters with special meaning in a URI.
