패럴랙스 효과06
자바스크립트를 이용하여 패럴랙스 효과를 만들 수 있습니다. 글씨가 하나씩 쪼개져서 나타나는 효과를 만들었습니다.
자바스크립트
패럴랙스 효과를 만들기 위한 자바스크립트 작성법입니다.
// 글씨 나누기
// let text = document.querySelector("#section1 .content__item__desc");
// let splitText = text.innerText;
// let splitWrap = splitText.split('').join('</span><span>');
// text.innerHTML = splitWrap = "<span>" + splitWrap + "</span>";
//글씨 쪼개기(다중이)
// text.forEach((e, i) => {
// let splitText = e.innerText;
// let splitWrap = splitText.split('').join('</span><span>');
// e.innerHTML = splitWrap = "<span>" + splitWrap + "</span>";
// console.log(splitWrap);
// });
document.querySelectorAll(".split").forEach(text => {
let splitText = text.innerText;
let splitWrap = splitText.split('').join("</span><span aria-hidden='true'>"); //시각리더기가 한 글자씩 끊어서 읽는 문제 발생. 접근성 저하
splitWrap = "<span aria-hidden='true'>" + splitWrap + "</span>";
text.innerHTML = splitWrap;
text.setAttribute("aria-label", splitText); //접근성을 위해 setAttribute사용. setAttribute : 선택한 요소(element)의 속성(attribute) 값을 부여
});
function scroll() {
let scrollTop = window.scrollY // == window.pageYOffset;
document.querySelector("#parallax__info .scroll").innerText = Math.round(scrollTop);
// CSS 클래스 추가(노가다 방법)
// document.querySelectorAll(".content__item").forEach(item => { //선택자에 split을 넣으면 한 번에 나오는 오류가 생겨서 부모박스 선택
// if (scrollTop >= item.offsetTop) {
// item.querySelector(".split").classList.add("show");
// }
// })
document.querySelectorAll(".content__item").forEach(item => {
if (scrollTop >= item.offsetTop) {
item.querySelector(".split").classList.add("show") //split에 show class 추가
item.querySelectorAll(".split span").forEach((span, index) => {
span.style.transitionDelay = `${index * 50}ms`; //index 이용하여 transition-delay효과 추가
// console.log(span[index])
});
}
});
requestAnimationFrame(scroll);
}
scroll();
HTML
패럴랙스 효과를 만들기 위한 HTML 작성법입니다. 글씨 쪼개기 효과를 위해 ".content__item__desc" 옆에 ".split" 클래스도 추가하였습니다.

CSS
패럴랙스 효과를 만들기 위한 CSS 작성법입니다. 쪼개어진 글씨에 띄어쓰기가 적용되지 않아 min-width: 1vw;로 간격을 주었습니다.
