How Can I Implement Smooth Scrolling for Anchor Links in My Website?
Dec 09, 2024 am 03:45 AM
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.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
