03. script 코드
먼저 preventDefault()로 클릭시 이동하는 이벤트를 막아줍니다.
getAttribute로 parallax__dot의 href 속성을 가져오고 scrollIntoView를
이용해 요소를(#section) 기준으로 스크롤을 이동시켜줍니다.
if문을 이용해서 parallax__dot의 li의 active를 제거해주고 클릭한 li에 active를 추가해줍니다.
{
document.querySelectorAll("#parallax__dot a").forEach(el => {
el.addEventListener("click", e => {
e.preventDefault();
// 이동 막음
document.querySelector(el.getAttribute("href")).scrollIntoView({behavior: "smooth"});
})
});
window.addEventListener("scroll", () => {
let scrollTop = window.pageYOffset || window.scrollY || document.documentElement.scrollTop;
// 스크롤바 현재 위치 scrollTop에 저장
document.querySelector("#parallax__info span").innerText = Math.floor(scrollTop);
// 소수점 제거
document.querySelectorAll(".content__item").forEach((e,i)=>{
if(scrollTop >= e.offsetTop - 10){
//-10 이유 : 오차 고려
document.querySelectorAll("#parallax__dot li").forEach(li => {
li.classList.remove("active")
});
document.querySelector("#parallax__dot li:nth-child("+(i+1)+")").classList.add("active");
}
})
});
// window.scroll(0, 1000);
// window.scroll({left: 0, top: 2000});
// window.scroll({left: 0, top: 2000, behavior:"smooth"});
// window.scrollTo(0, 1000);
// window.scrollTo({left: 0, top: 2000});
// window.scrollTo({left: 0, top: 2000, behavior:"smooth"});
// window.scrollBy(0, 1000);
// window.scrollBy({left: 0, top: 2000});
// window.scrollBy({left: 0, top: 2000, behavior:"smooth"});
