HTML DOM 요소 클래스 이름

❮ 요소 개체

예시

요소에 대한 클래스 속성을 설정합니다.

element.className = "myStyle";

"myDIV"의 클래스 속성을 가져옵니다.

let value = document.getElementById("myDIV").className;

두 클래스 이름 간 전환:

if (element.className == "myStyle") {
  element.className = "newStyle";
} else {
  element.className = "myStyle";
}

아래에 더 많은 예가 있습니다.


정의 및 사용

속성은 요소 의 className클래스 속성을 설정하거나 반환합니다.


통사론

className 속성을 반환합니다.

HTMLElementObject.className

className 속성을 설정합니다.

HTMLElementObject.className = class

속성 값

Value Description
class The class name(s) of an element.
Separate multiple classes with spaces, like "test demo".


반환 값

Type Description
StringThe class, or a space-separated list of classes, of an element

더 많은 예

첫 번째 <div> 요소의 클래스 속성을 가져옵니다(있는 경우):

let value = document.getElementsByTagName("div")[0].className;

여러 클래스가 있는 클래스 속성 가져오기:

<div id="myDIV" class="myStyle test example">
<p>I am myDIV.</p>
</div>
let value = document.getElementById("myDIV").className;

기존 클래스 속성을 새 속성으로 덮어씁니다.

element.className = "newClassName";

기존 값을 덮어쓰지 않고 새 클래스를 추가하려면 공백과 새 클래스를 추가하십시오.

element.className += " class1 class2";

"myDIV"에 "myStyle" 클래스가 있는 경우 글꼴 크기를 변경합니다.

const elem = document.getElementById("myDIV");

if (elem.className == "mystyle") {
  elem.style.fontSize = "30px";
}

이 페이지 상단에서 50픽셀 스크롤하면 "test" 클래스가 추가됩니다.

window.onscroll = function() {myFunction()};

function myFunction() {
  if (document.body.scrollTop > 50) {
    document.getElementById("myP").className = "test";
  } else {
    document.getElementById("myP").className = "";
  }
}
