기존의 toggleOpen
함수는 액티브된 요소가 있는 상태에서 액티브되지 않은 요소를 클릭하면 기존의 액티브된 요소의 액티브 클래스를 지우지 못해서 남아있었다. 그리고 기존 toggleActive
함수는 각 구역을 빠르게 클릭하면 액티브된 요소의 클래스가 반대로 적용되는 오류가 있었다.
이 부분을 챗GPT를 통해 수정해보았다.
const panels = document.querySelectorAll(".panel");
function toggleOpen() {
// 현재 클릭한 panel에 'open' 클래스를 추가
this.classList.toggle("open");
// 다른 panel에서 'open' 클래스를 제거
panels.forEach((panel) => {
if (panel !== this && panel.classList.contains("open")) {
panel.classList.remove("open");
}
});
// transitionend 이벤트가 중복으로 발생하지 않도록 임시로 click 이벤트 제거
panels.forEach((panel) => panel.removeEventListener("click", toggleOpen));
}
function toggleActive(e) {
if (e.propertyName.includes("flex")) {
this.classList.toggle("open-active");
// click 이벤트 다시 추가
panels.forEach((panel) => panel.addEventListener("click", toggleOpen));
}
}
panels.forEach((panel) => panel.addEventListener("click", toggleOpen));
panels.forEach((panel) =>
panel.addEventListener("transitionend", toggleActive)
);
질문을 좀 더 자세하게 하지 못해서 100% 만족하는 결과는 아니었지만 그래도 나름 괜찮을 결과였다.
