Implementing window.scrollBy JavaScript with Example Codes
Let’s prove how to apply the window.scrollBy method in different cases with practical examples:
Example of Smooth Scrolling to a Section
document.querySelector('#scrollToSectionBtn').addEventListener('click', () => {

}
});
Implement infinite scrolling by detecting when the user reaches the bottom of the page.
Custom Scrolling Animation
const scrollDurationFunction = 2000;
document.querySelector('#animateScrollBtn').addEventListener('click', () => {
const start = window.scrollY;
const end = 700;
const startTime = performance.now();
function scrollStep(timestamp) {
const progressFunction = (timestamp - startTime) / scrollDurationFunction;
window.scrollTo(0, start + (end - start) * Math.min(progressFunction, 1));
if (progressFunction < 1) {
requestAnimationFrame(scrollStep);
}
}
requestAnimationFrame(scrollStep);
});
Create a customized scrolling animation using requestAnimationFrame.
