How Can I Implement Smooth Scrolling for Anchor Links in My Website?

Enhancing Anchor Link Navigation with Smooth Scrolling

Smooth scrolling can significantly improve the user experience when navigating through your web page using anchor links. By eliminating jarring jumps and providing a seamless transition, you enhance the page's accessibility and overall aesthetics.

Using Native JavaScript

Recent versions of major browsers now support native smooth scrolling for anchor links. You can implement this functionality using the following code:

document.querySelectorAll('a[href^="#"]').forEach(anchor => {
  anchor.addEventListener('click', e => {
    e.preventDefault();
    document.querySelector(anchor.getAttribute('href')).scrollIntoView({ behavior: 'smooth' });
  });
});

jQuery Solution

For older browser compatibility, jQuery offers a reliable solution:

$(document).on('click', 'a[href^="#"]', event => {
  event.preventDefault();
  $('html, body').animate({ scrollTop: $($.attr(this, 'href')).offset().top }, 500);
});

Handling Target Elements Without IDs

If the target element lacks an ID but is linked to by name, use the following code:

$('a[href^="#"]').click(function () {
  $('html, body').animate({ scrollTop: $('[name="' + $.attr(this, 'href').substr(1) + '"]').offset().top }, 500);
  return false;
});

Performance Optimization

For efficiency, it's recommended to cache the $('html, body') selector:

var $root = $('html, body');

$('a[href^="#"]').click(function () {
  $root.animate({ scrollTop: $( $.attr(this, 'href') ).offset().top }, 500);
  return false;
});

Updating the URL

To update the URL during the scrolling animation, include the following code within the callback:

var $root = $('html, body');

$('a[href^="#"]').click(function() {
  var href = $.attr(this, 'href');
  $root.animate({ scrollTop: $(href).offset().top }, 500, () => { window.location.hash = href; });
  return false;
});

By incorporating these techniques, you can provide a seamless and engaging navigation experience for your website users, making it a joy to navigate through the page's content.
