Intersection Observer

Last updated at Posted at 2021-10-03

Intersection Observerを使ってみた。

javascript
const targetEle = document.querySelector(".targetEle");
const cb = function (entries, observer) {
    entries.forEach(entry => {
        if (entry.isIntersecting) {
            entry.target.classList.add("inview")
        } else {
            entry.target.classList.remove("inview")
        }
    })
}
const io = new IntersectionObserver(cb, options);
io.observe(targetEle)
