I recently stumbled across a nifty little browser feature when I had to solve the following task: scroll to an element on the page and if possible: scroll to it smoothly. The last time I had to solve this kind of task was when jQuery was everywhere. So I thought it’s a good time to check how it can be solved in 2018 without jQuery.

Scrolling with a JavaScript/Browser API

element.scrollIntoView() is a browser API that exists since Internet Explorer 6, so it’s obviously a really old API. When calling this method, the browser scrolls to the given element (what a surprise!) and that is nothing new:

document.querySelector('.my-div').scrollIntoView();

The only downside of this is the scrolling itself: it’s not smooth. The user sees the element immediately which can be irritating. So how can we scroll smoothly?

It’s possible to provide a configuration for the scrollIntoView method (the name of this configuration is scrollIntoViewOptions ). To enable the smooth scrolling, we simply add this option:

document.querySelector('.my-div').scrollIntoView({ behavior: 'smooth' });

Browser support of scrollIntoViewOptions

The bad news is: smooth scrolling with the shown configuration is only supported in Chrome and Firefox right now.

Adddng cross browser support

The good news is: there’s a polyfill that adds support for scrollIntoViewOptions in all browsers that support requestAnimationFrame : https://github.com/iamdustan/smoothscroll:

// run "npm install smoothscroll-polyfill" before import { smoothscroll } from 'smoothscroll-polyfill'; smoothscroll.polyfill(); // this should work now document.querySelector('.my-div').scrollIntoView({ behavior: 'smooth' });

That’s a Wrap

Enabling smooth scrolling with pure browser API is the way to go. The sad thing about this is the low browser support right now. Thanks to the polyfill author that we can use this feature in all commonly used browsers today.

I hope you liked this quick JavaScript tip 😎. I plan to add more of these little posts in the future.
