창 setInterval()

1초마다 "Hello" 표시(1000밀리초):

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

매초마다 displayHello를 호출합니다.

setInterval(displayHello, 1000);

아래에 더 많은 예가 있습니다.


정의 및 사용

메서드 는 setInterval()지정된 간격(밀리초)으로 함수를 호출합니다.

메서드 는 가 호출되거나 창이 닫힐 setInterval()때까지 함수를 계속 호출합니다 .clearInterval()

1초 = 1000밀리초.

메모

함수를 한 번만 실행하려면 setTimeout()대신 메서드를 사용하십시오.

간격을 지우려면 setInterval()에서 반환된 ID 를 사용합니다.

myInterval = setInterval(function, milliseconds);

그런 다음 clearInterval()을 호출하여 실행을 중지할 수 있습니다.

clearInterval(myInterval);

통사론

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

매개변수

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.

반환 값

유형 설명
번호타이머의 ID입니다.
이 ID를 clearInterval()과 함께 사용하여 타이머를 취소합니다.

예시

디지털 시계처럼 시간 표시:

setInterval(myTimer, 1000);

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

예시

clearInterval()을 사용하여 디지털 시계 중지:

const myInterval = setInterval(myTimer, 1000);

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

function myStopFunction() {
  clearInterval(myInterval);
}

예시

setInterval() 및 clearInterval()을 사용하여 동적 진행률 표시줄 만들기:

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 + '%';
    }
  }
}

예시

500밀리초마다 한 번씩 두 배경색 사이를 전환합니다.

const myInterval = setInterval(setColor, 500);

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

function stopColor() {
  clearInterval(myInterval);
}

예시

함수에 매개변수 전달(IE9 및 이전 버전에서는 작동하지 않음):

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

그러나 익명 기능을 사용하면 모든 브라우저에서 작동합니다.

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

브라우저 지원

setInterval()모든 브라우저에서 지원됩니다:
