How to Automatically Scroll to the Last Article in a Form Using JavaScript
Scrolling to different parts of a webpage can greatly enhance user experience, especially when dealing with forms that include multiple articles or comments. If you find yourself needing to jump to the last article in a form with a button click, you're not alone! Many developers face this challenge, particularly when trying to accommodate dynamic content. In this guide, we’ll discuss simple methods to implement this functionality using JavaScript.
The Challenge
Imagine you have a form filled with a dynamic number of articles or comments, and you want to create a button that automatically scrolls to the last article when clicked. A common problem encountered is that articles can have varying heights, making percentage-based scrolling ineffective. Instead, we can use the last-child selector in DOM manipulation to achieve our goal.
For this example, let’s consider the following button and form structure:

Solution Approaches
There are two effective methods to achieve this functionality: using only HTML or incorporating JavaScript. Let’s explore both options in detail.
Method 1: HTML Method with Anchor Link
If you prefer a solution that doesn't require JavaScript, you can use an HTML anchor link approach.
Create an Empty Element: Place an empty div or a wrapper around or above the last article that can serve as an anchor point.

This approach allows you to create a smooth scroll without any JavaScript.
Method 2: JavaScript Scroll Method
If you'd like to add more interactivity with JavaScript, follow these steps:
Define a JavaScript Function: Create a function that targets the last article and scrolls to it.

Start experimenting with the code snippets provided, and soon you’ll be able to give your users quick access to the latest content on your forms!
