Let User Scrolling Stop Jquery Animation Of Scrolltop

Have you ever wanted to create a smooth scrolling effect on your webpage using jQuery, but also want this animation to stop if the user manually scrolls? In this article, we will explore how you can achieve just that by pausing the scroll animation when the user interacts with the page.

One common scenario in web development is implementing a smooth scrolling effect using jQuery's `scrollTop` function. This feature enhances user experience by providing a more polished and visually appealing transition between sections of a webpage.

However, a challenge arises when the user decides to take control and manually scroll the page. In such cases, it is beneficial to allow the user's scrolling action to take precedence over any ongoing jQuery animation to avoid a jarring experience.

To achieve this, we can utilize event listeners to detect when the user interacts with the scroll bar and subsequently pause the jQuery animation. The `scroll` event in jQuery provides the functionality to monitor scrolling movements on the page.

First, you need to define a boolean variable, let's call it `isAnimating`, to keep track of whether the jQuery animation is currently in progress. By default, this variable is set to `false`.

let isAnimating = false;

Next, you can start the smooth scrolling animation using jQuery. Here's a simple example to animate the scroll top position of the page:

$('html, body').animate({ scrollTop: 500 }, 1000, function() {
    isAnimating = false;
});
isAnimating = true;

In the above code snippet, we animate the `scrollTop` property to `500` pixels over a duration of `1000` milliseconds. Upon completion of the animation, the `isAnimating` variable is set to `false`.

Now, let's add a scroll event listener to detect when the user manually scrolls the page:

$(window).on('scroll', function() {
    if (isAnimating) {
        $('html, body').stop();
        isAnimating = false;
    }
});

In the scroll event listener, we check if the `isAnimating` flag is set to `true`, indicating that the jQuery animation is active. If so, we call the `stop` method to halt the animation and set `isAnimating` to `false`.

By incorporating this logic into your code, you can seamlessly blend the smooth scrolling animation with user-initiated scrolling actions. This approach enhances the user experience by providing a responsive and intuitive interface.

In conclusion, by implementing event listeners and leveraging jQuery's functionality, you can create a dynamic and user-friendly scrolling experience on your webpages. Whether you're designing a portfolio, blog, or e-commerce site, incorporating these techniques can elevate the overall quality of your web design.
