Section 1.1 Utilizing the window.scrollTo Method

To scroll to specific coordinates on a webpage when a link with a hash in its href is clicked, we can leverage the window.scrollTo method.

For example, the following HTML snippet can be used:

<a href='#'>link 1</a>

<a href='#foo'>link 2</a>

<a href='#bar'>link 3</a>

<div id='bar' style='height: 500px'>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</div>

<div id='foo' style='height: 500px'>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</div>

Next, we define a function to handle the offset:

const offsetAnchor = () => {

if (location.hash.length !== 0) {

window.scrollTo(window.scrollX, window.scrollY - 100);

}

};

We then select all anchor tags that contain a hash in their href attribute:

const anchors = document.querySelectorAll('a[href^="#"]');

for (const a of anchors) {

a.addEventListener('click', (event) => {

window.setTimeout(() => {

offsetAnchor();

}, 0);

});

}

Additionally, we add an event listener to the document itself:

document.addEventListener('click', (event) => {

window.setTimeout(() => {

offsetAnchor();

}, 0);

});

Finally, we invoke the offsetAnchor function initially to ensure that the page starts at the correct coordinates.

Section 1.2 Conclusion

In summary, the window.scrollTo method can be effectively used to adjust the scroll position when clicking on anchor links with hashes. This technique ensures a smoother user experience by allowing for slight adjustments in scroll position.
