Fungsi Scroll
fungsi ini berfungsi untuk mengubah status navbar menjadi sticky, dan tambahkan juga animasi smooth agar proses perpindahan halamannya menjadi bagus
const [navClass, setNavClass] = React.useState<string>('');
const scrollNavigation = () => {
var scrollUp = document.documentElement.scrollTop;
if (scrollUp >= 50) {
setNavClass('is-sticky');
} else {
setNavClass('');
}
};
React.useEffect(() => {
window.addEventListener('scroll', scrollNavigation, true);
document.documentElement.classList.add("overflow-x-hidden", "scroll-smooth", "group");
return () => {
window.removeEventListener('scroll', scrollNavigation, true);
document.documentElement.classList.remove("overflow-x-hidden", "scroll-smooth", "group");
};
}, []);
Fungsi Set Active menu
fungsi ini berfungsi untuk merubah class aktif yang ada pada menu, dan mengarahkan halaman sesuai deangan menu yang di akses
const [activeLink, setActiveLink] = React.useState<string>("/Home");
const handleLinkClick = (target: string) => {
setActiveLink(target);
};
Script lengkapnya seperti berikut
import React from "react"
function App() {
const [navClass, setNavClass] = React.useState<string>('');
const scrollNavigation = () => {
var scrollUp = document.documentElement.scrollTop;
if (scrollUp >= 50) {
setNavClass('is-sticky');
} else {
setNavClass('');
}
};
React.useEffect(() => {
window.addEventListener('scroll', scrollNavigation, true);
document.documentElement.classList.add("overflow-x-hidden", "scroll-smooth", "group");
return () => {
window.removeEventListener('scroll', scrollNavigation, true);
document.documentElement.classList.remove("overflow-x-hidden", "scroll-smooth", "group");
};
}, []);
const [activeLink, setActiveLink] = React.useState<string>("/Home");
const handleLinkClick = (target: string) => {
setActiveLink(target);
};
