Venster stelTimeout()

Voorbeelde

Wag 5 sekondes vir die groet:

const myTimeout = setTimeout(myGreeting, 5000);

Gebruik clearTimeout(myTimeout) om te verhoed dat myGreeting loop:

const myTimeout = setTimeout(myGreeting, 5000);

function myStopFunction() {
  clearTimeout(myTimeout);
}

Meer voorbeelde hieronder.


Definisie en gebruik

Die setTimeout()metode roep 'n funksie na 'n aantal millisekondes.

1 sekonde = 1000 millisekondes.

Notas

Die setTimeout()word slegs een keer uitgevoer.

As jy herhaalde teregstellings nodig het, gebruik setInterval()eerder.

Gebruik die clearTimeout()metode om te verhoed dat die funksie begin.

Om 'n uitteltyd uit te vee, gebruik die ID wat van setTimeout():

myTimeout = setTimeout(function, milliseconds);

Dan kan jy die uitvoering stop deur clearTimeout ():

clearTimeout(myTimeout);

Sintaksis

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

Grense

Parameter Description
function Required.
The function to execute.
milliseconds Optional.
Number of milliseconds to wait before executing.
Default value is 0.
param1,
param2,
...
Optional.
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 clearTimeout(id) om die timer te kanselleer.


Meer voorbeelde

Vertoon 'n waarskuwingskassie na 3 sekondes (3000 millisekondes):

let timeout;

function myFunction() {
  timeout = setTimeout(alertFunc, 3000);
}

function alertFunc() {
  alert("Hello!");
}

Vertoon 'n tydige teks:

let x = document.getElementById("txt");
setTimeout(function(){ x.value = "2 seconds" }, 2000);
setTimeout(function(){ x.value = "4 seconds" }, 4000);
setTimeout(function(){ x.value = "6 seconds" }, 6000);

Maak 'n nuwe venster oop en maak die venster toe na drie sekondes (3000 millisekondes):

const myWindow = window.open("", "", "width=200, height=100");
setTimeout(function() {myWindow.close()}, 3000);

Tel vir ewig - maar met die vermoë om die telling te stop:

function startCount()
function stopCount()

'n Horlosie geskep met tydsberekening gebeurtenisse:

function startTime() {
  const date = new Date();
  document.getElementById("txt").innerHTML = date.toLocaleTimeString();
  setTimeout(function() {startTime()}, 1000);
}

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

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

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

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