Js.Global

Provide bindings to JS global functions in global namespace

intervalId

RESCRIPT

type intervalId

Identify an interval started by Js.Global.setInterval.

timeoutId

RESCRIPT

type timeoutId

Identify timeout started by Js.Global.setTimeout.

clearInterval

RESCRIPT

let clearInterval: intervalId => unit

Clear an interval started by Js.Global.setInterval

Examples

RESCRIPT
/* API for a somewhat aggressive snoozing alarm clock */

let punchSleepyGuy = () => Js.log("Punch")

let interval = ref(Js.Nullable.null)

let remind = () => {
  Js.log("Wake Up!")
  punchSleepyGuy()
}

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

let cancel = () =>
  Js.Nullable.iter(interval.contents, (. intervalId) => Js.Global.clearInterval(intervalId))

clearTimeout

RESCRIPT

let clearTimeout: timeoutId => unit

Clear a timeout started by Js.Global.setTimeout.

Examples

RESCRIPT
/* A simple model of a code monkey's brain */

let closeHackerNewsTab = () => Js.log("close")

let timer = ref(Js.Nullable.null)

let work = () => closeHackerNewsTab()

let procrastinate = mins => {
  Js.Nullable.iter(timer.contents, (. timer) => Js.Global.clearTimeout(timer))
  timer := Js.Nullable.return(Js.Global.setTimeout(work, mins * 60 * 1000))
}

setInterval

RESCRIPT

let setInterval: (unit => unit, int) => intervalId

Repeatedly executes a callback with a specified interval (in milliseconds) between calls. Returns a Js.Global.intervalId that can be passed to Js.Global.clearInterval to cancel the timeout.

Examples

RESCRIPT
/* Will count up and print the count to the console every second */

let count = ref(0)

let tick = () => {
  count := count.contents + 1
  Js.log(Belt.Int.toString(count.contents))
}

Js.Global.setInterval(tick, 1000)

setIntervalFloat

RESCRIPT

let setIntervalFloat: (unit => unit, float) => intervalId

Repeatedly executes a callback with a specified interval (in milliseconds) between calls. Returns a Js.Global.intervalId that can be passed to Js.Global.clearInterval to cancel the timeout.

Examples

RESCRIPT
/* Will count up and print the count to the console every second */

let count = ref(0)

let tick = () => {
  count := count.contents + 1
  Js.log(Belt.Int.toString(count.contents))
}

Js.Global.setIntervalFloat(tick, 1000.0)

setTimeout

RESCRIPT

let setTimeout: (unit => unit, int) => timeoutId

Execute a callback after a specified delay (in milliseconds). Returns a Js.Global.timeoutId that can be passed to Js.Global.clearTimeout to cancel the timeout.

Examples

RESCRIPT
/* Prints "Timed out!" in the console after one second */

let message = "Timed out!"

Js.Global.setTimeout(() => Js.log(message), 1000)

setTimeoutFloat

RESCRIPT

let setTimeoutFloat: (unit => unit, float) => timeoutId

Execute a callback after a specified delay (in milliseconds). Returns a Js.Global.timeoutId that can be passed to Js.Global.clearTimeout to cancel the timeout.

Examples

RESCRIPT
/* Prints "Timed out!" in the console after one second */

let message = "Timed out!"

Js.Global.setTimeoutFloat(() => Js.log(message), 1000.0)

encodeURI

RESCRIPT

let encodeURI: string => string

URL-encodes a string.

see MDN

decodeURI

RESCRIPT

let decodeURI: string => string

Decodes a URL-enmcoded string produced by encodeURI

see MDN

encodeURIComponent

RESCRIPT

let encodeURIComponent: string => string

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

see MDN

decodeURIComponent

RESCRIPT

let decodeURIComponent: string => string

Decodes a URL-enmcoded string produced by encodeURIComponent

see MDN
