![]() I made a PR to slightly improve the docs, you might find the code easier to understand with it. If you have more curiosity, I highly suggest studying the polyfill's source code, it's less than 500 lines in total. It does not support smooth scrolling by setting scrollLeft/ scrollTop and it does not support the scrollIntoView() options (it always aligns the element at the top). It polyfills scroll(), scrollTo(), scrollBy(), scrollIntoView() and the CSS scroll-behavior. If you need more reassurance, there's a very good smooth scroll polyfill that I use in my projects. scrollTo ( As of this writing, all major browsers – except Safari – support smooth scroll and the scrolling methods described in this article. There's also a new signature for this method, which uses an object instead of two numeric arguments, and with this new signature, we can explicitly set our scroll behavior. If you are importing it as a dependency, make sure to call the polyfill method: import smoothscroll from 'smoothscroll-polyfill' // kick off the polyfill smoothscroll. You simply call element.scrollTo(x, y) and it'll respect the CSS scroll-behavior of the element. When including the polyfill in a script tag, it will run immediately after loaded. polyfill () In both cases, the script will detect if the spec is natively supported and take action only when necessary. If you have the x and y coordinates for where you want to scroll the user to, you can simply call window.scrollTo(x, y) and it'll respect the CSS scroll-behavior of the page. import smoothscroll from 'smoothscroll-polyfill' // kick off the polyfill smoothscroll. Use this online smoothscroll-polyfill playground to view and fork smoothscroll-polyfill example apps and templates on CodeSandbox. This method is ideal for scrolling to absolute coordinates. Link Window.scrollTo() and Element.scrollTo() Stimulus Component is an MIT licensed open source project and completely free. In practice, you can use either, just choose one and be consistent. You can easily add it with this polyfill: smoothscroll-polyfill. To avoid duplicate content, I'll just refer to scrollTo(). That's because Window.scroll() and Element.scroll() are effectively the same methods as Window.scrollTo() and Element.scrollTo(). Maybe you've noticed that I haven't mentioned the scroll() method. You can easily change scroll duration and easing, as well as listen for custom events so that your own code can react appropriately to scroll starts and stops. Link (Note) Window.scroll() and Element.scroll() SmoothScroller is a JavaScript module that provides easy-to-use and customizable smooth scrolling functionality for your website. We'll explore these methods individually. Ğlement.scrollTop = y JavaScript - Window. Some ways of programmatically triggering a scroll event are through: - Window.scrollTo() I say "programmatically triggered" because it's not going to smooth scroll the mouse wheel. scroll-behavior: smooth applies a smooth transition when a scroll event is programmatically triggered.scroll-behavior: instant is the same as auto, which is why it was deprecated.scroll-behavior: auto is the default instant scrolling behavior that we're already used to.The CSS scroll-behavior property accepts one of three values – or two, actually, since one of those was deprecated. Let me introduce you to our tools for a native smooth scroll. ![]() Var locationPath = filterPath(location.Menu Table of Contents CSS scroll-behavior (Note) Window.scroll() and Element.scroll() Window.scrollTo() and Element.scrollTo() Element.scrollLeft and Element.scrollTop (Note) Negative Element.scrollLeft Window.scrollBy() and Element.scrollBy() (Note) Window.scrollByLines() and Window.scrollByPages() Element.scrollIntoView() Browser Support CTA Referencesĭo you want a smooth scroll? Forget JQuery, we're past that. Hey! Before you go too far down the rabbit hole of JavaScript-based smooth scrolling, know that there is a native CSS feature for this: scroll-behavior.
