Venster stelInterval()

Voorbeelde

Wys "Hallo" elke sekonde (1000 millisekondes):

setInterval(function () {element.innerHTML += "Hello"}, 1000);

Bel displayHallo elke sekonde:

setInterval(displayHello, 1000);

Meer voorbeelde hieronder.


Definisie en gebruik

Die setInterval()metode roep 'n funksie op met gespesifiseerde intervalle (in millisekondes).

Die setInterval()metode gaan voort om die funksie te roep totdat clearInterval()dit geroep word, of die venster gesluit word.

1 sekonde = 1000 millisekondes.

Let wel

Om die funksie net een keer uit te voer, gebruik setTimeout()eerder die metode.

Om 'n interval skoon te maak, gebruik die id wat van setInterval():

myInterval = setInterval(function, milliseconds);

Dan kan jy die uitvoering stop deur clearInterval():

clearInterval(myInterval);

Sintaksis

setInterval(function, milliseconds, param1, param2, ...)

Grense

Parameter Description
function Required.
The function to execute
milliseconds Required.
The execution interval.
If the value is less than 10, 10 is used
param1, param2, ... Optional.
Additional parameters to pass to the function
Not supported in IE9 and earlier.

Terugkeerwaarde

Tik Beskrywing
N nommerDie ID van die timer.
Gebruik hierdie id met clearInterval() om die timer te kanselleer.


Meer voorbeelde

Voorbeeld

Wys die tyd soos 'n digitale horlosie:

setInterval(myTimer, 1000);

function myTimer() {
  const date = new Date();
document.getElementById("demo").innerHTML = date.toLocaleTimeString();
}

Voorbeeld

Gebruik clearInterval() om die digitale horlosie te stop:

const myInterval = setInterval(myTimer, 1000);

function myTimer() {
  const date = new Date();
  document.getElementById("demo").innerHTML = date.toLocaleTimeString();
}

function myStopFunction() {
  clearInterval(myInterval);
}

Voorbeeld

Gebruik setInterval() en clearInterval() om 'n dinamiese vorderingsbalk te skep:

function move() {
  const element = document.getElementById("myBar");
  let width = 0;
  let id = setInterval(frame, 10);
  function frame() {
    if (width == 100) {
      clearInterval(id);
    } else {
      width++;
      element.style.width = width + '%';
    }
  }
}

Voorbeeld

Wissel tussen twee agtergrondkleure een keer elke 500 millisekondes:

const myInterval = setInterval(setColor, 500);

function setColor() {
  let x = document.body;
  x.style.backgroundColor = x.style.backgroundColor == "yellow" ? "pink" : "yellow";
}

function stopColor() {
  clearInterval(myInterval);
}

Voorbeeld

Slaag parameters na die funksie (werk nie in IE9 en vroeër nie):

setInterval(myFunc, 2000, "param1", "param2");

As jy egter 'n anonieme funksie gebruik, werk dit in alle blaaiers:

setInterval(function() {myFunc("param1", "param2")}, 2000);
