실시예 1

화면/뷰포트가 너비가 700픽셀을 초과합니까?

  // Viewport is less or equal to 700 pixels wide
} else {
  // Viewport is greater than 700 pixels wide
}

MediaQueryList 개체


미디어 쿼리

메서드 의 미디어 쿼리는 최소 높이, 최소 너비, 방향 등과 같은 CSS @media 규칙matchMedia() 의 미디어 기능 중 하나일 수 있습니다 .

matchMedia("(max-height: 480px)").matches);
matchMedia("(max-width: 640px)").matches);

통사론

window.matchMedia(mediaQuery)

매개변수

Parameter Description
mediaQuery Required.
A string representing a media query.

반환 값

유형 설명
객체미디어 쿼리 결과가 포함된 MediaQueryList 개체입니다.


설명된 예

이 페이지의 첫 번째 예는 미디어 쿼리를 실행하고 현재 창 상태와 비교합니다.

창 상태가 변경 될 때마다 반응형 미디어 쿼리 를 실행하려면 MediaQueryList 개체에 이벤트 리스너를 추가합니다(아래 "추가 예제" 참조).


더 많은 예

뷰포트 너비가 500픽셀보다 작거나 같으면 배경색을 노란색으로 설정하고 그렇지 않으면 분홍색으로 설정합니다.

// Create a match function
function myFunction(x) {
  if (x.matches) {
    document.body.style.backgroundColor = "yellow";
  } else {
    document.body.style.backgroundColor = "pink";
  }
}

// // Create a MediaQueryList object
const mmObj = window.matchMedia("(max-width: 700px)")

// Call the match function at run time:
myFunction(mmObj);

// Add the match function as a listener for state changes:
mmObj.addListener(myFunction);

브라우저 지원

matchMedia() 모든 최신 브라우저에서 지원됩니다.
