Scrolling To A Element Inside A Scrollable Div With Pure Javascript

Scrolling to a specific element inside a scrollable div using pure JavaScript can be a handy feature to enhance user experience on your website. In this article, we'll walk through the steps to achieve this functionality effortlessly.

Firstly, let's set up our HTML structure. You'll need a parent container with a fixed height that will act as the scrollable element. Inside this container, include the elements you want to scroll to, each identifiable by a unique ID.

Next, onto the JavaScript magic! We will create a function that scrolls the parent container to the desired element when triggered. Here's a step-by-step guide to implement this functionality:

1. Retrieve the parent container and the target element using document.getElementById(), assigning them to variables for easy access later on.

2. Calculate the offsetTop of the target element relative to the parent container. This will help us determine how much we need to scroll to bring the element into view.

3. Update the scrollTop property of the parent container to the calculated offsetTop value. This will smoothly scroll the container to the target element.

To implement these steps, you can create a function like scrollToElement() as shown below:

function scrollToElement(elementId) {
    const parentContainer = document.getElementById('parent-container');
    const targetElement = document.getElementById(elementId);
    
    if (targetElement) {
        const offsetTop = targetElement.offsetTop - parentContainer.offsetTop;
        parentContainer.scrollTop = offsetTop;
    }
}

You can call this function with the ID of the target element you want to scroll to, like so:

scrollToElement('target-element-id');

Remember to replace 'parent-container' with the ID of your actual parent container element and 'target-element-id' with the ID of the element you want to scroll to.

This simple function allows you to seamlessly scroll to any specific element inside a scrollable div. Feel free to customize it further based on your project's requirements, such as adding smooth scrolling effects or offset adjustments for better user experience.

In conclusion, mastering the art of scrolling to elements within a scrollable div using pure JavaScript can significantly improve your website's usability. Incorporating this functionality will provide a seamless navigation experience for your users, enhancing the overall appeal of your web page.
