How To Scroll To Top Of Page With Javascript Jquery

Scrolling to the top of a webpage may seem like a small detail, but it can greatly improve user experience and navigation on your website. Whether you're a seasoned developer or just starting out with coding, knowing how to implement a "Scroll to Top" button can be a handy trick to have up your sleeve.

One popular way to achieve this functionality is by using JavaScript/jQuery. These versatile scripting languages can empower you to add dynamic features to your website with just a few lines of code. In this article, we'll guide you through the process of creating a smooth and user-friendly scroll to top button using JavaScript and jQuery.

Prerequisites:
Before we dive into the code, make sure you have a basic understanding of HTML, CSS, JavaScript, and jQuery. You can include jQuery in your project by adding the following CDN link to your HTML file:

Html

Code Implementation:
Here's a step-by-step guide on how to implement the scroll to top functionality using JavaScript and jQuery:

1. Create a button element in your HTML markup:

Html

<button id="scrollToTopBtn">Scroll to Top</button>

2. Style the button using CSS to position it fixed at the bottom right corner of the page:

Css

#scrollToTopBtn {
  position: fixed;
  bottom: 20px;
  right: 20px;
  display: none;
}

3. Write the JavaScript/jQuery code to show/hide the button and scroll to the top when clicked:

Javascript

$(document).ready(function() {
  $(window).scroll(function() {
    if ($(this).scrollTop() &gt; 100) {
      $('#scrollToTopBtn').fadeIn();
    } else {
      $('#scrollToTopBtn').fadeOut();
    }
  });
  
  $('#scrollToTopBtn').click(function() {
    $('html, body').animate({ scrollTop: 0 }, 800);
    return false;
  });
});

Explanation:
- The `$(document).ready()` function ensures that the script runs only after the HTML document is fully loaded.
- The `$(window).scroll()` function detects when the user scrolls the page and toggles the visibility of the scroll to top button based on the scroll position.
- When the button is clicked, the `animate()` function smoothly scrolls the page to the top over 800 milliseconds.

Testing and Customization:
After implementing the code, test the functionality on your website to ensure it works as expected. Feel free to customize the button styling, animation duration, or scroll offset to suit your design preferences.

In conclusion, adding a scroll to top button using JavaScript/jQuery is a simple yet effective way to enhance user experience on your website. By following the steps outlined in this article, you can empower your site visitors to navigate seamlessly to the top of the page with just a single click.
