水平平滑动量滚动

Question

THE PROBLEM: I need to apply some mouse wheel smooth horizontal scrolling to this layout: https://jsfiddle.net/38qLnzkh/ .

ALTERNATIVE: I've found this Script that does exactly what I want but it seems to work only vertically: Butter.js . If you can make it work Horizontally it would probably solve all my problems.

IMPORTANT:

1. The Script should be disabled based on screen width and in touch devices.

2. It should accommodate a menu on top of everything like you seen in the fiddle.

Thank you in advance.

EDIT: In case it's not clear what I need, here are two examples with the effect I'm looking for:

MY LAYOUT:

HTML:

<main class="outer-wrapper">
    <div class="wrapper">
        <article class="section" id="a"><h2>01</h2></article>
        <article class="section" id="b"><h2>02</h2></article>
        <article class="section" id="c"><h2>03</h2></article>
        <article class="section" id="d"><h2>04</h2></article>
        <article class="section" id="e"><h2>05</h2></article>
        <article class="section" id="f"><h2>06</h2></article>
    </div>
</main>

CSS:

.outer-wrapper {
  width: auto;
  height: 100vw;
  transform: rotate(-90deg) translateX(-100vh);
  transform-origin: top left;
  overflow-y: scroll;
  overflow-x: hidden;
  position: absolute;
  scrollbar-width: none;
  -ms-overflow-style: none;
}
::-webkit-scrollbar {
  display: none;
}

.wrapper {
  display: flex;
  flex-direction: row;
  width: auto;
  transform: rotate(90deg) translateY(-100vh);
  transform-origin: top left;
    margin: 0;
  padding: 0;
}

.section {
    color: #000;
  width: 100vw;
  height: 100vh;
}

I've published an API on github that can easily solve this problem, below you'll find the code to do what you want.

Compared to yours I've just added the js code and the <script> in the HTML.

If you want to know more about it, here you can find the documentation .

EDIT
Since the requirements have changed a little bit and the API has been updated I've modified the example below so that it better fits the question.

Main changes to the answer:

• Now the js is inside a init() method called onload
• The css styles have been modified ( transform:rotate brakes most of scrolling APIs)
• The support for the navbar's smooth scroll has been added
• The scrolling amount now depends on how much the user physically scrolls the mousewheel

2021 Update
With the 3.0 update this solution becomes slighlty inacurate so I've updated the code so that any future reader will have a proper answer.

 /* NEW ANSWER */ function init() { /* * Variables preparation */ let yourWrapperElement = document.getElementsByClassName("outer-wrapper")[0]; let whateverEaseFunctionYouWant = remaningScrollDistance => { return remaningScrollDistance / 15 + 1 }; //Added support for navbar menu's smooth scrolling uss.hrefSetup(); /* * As you asked for, we only apply the custom scrolling for desktop devices * by using the "wheel" event instead of the "scroll" or "touchmove" events. */ yourWrapperElement.addEventListener("wheel", event => { /* * We want to overwrite the default scrolling behaviour * of your outer-wrapper component. */ event.preventDefault(); event.stopPropagation(); uss.scrollXBy(event.deltaY, yourWrapperElement, null, false); }, {passive:false}); /* * We apply a the custom ease function * which will be used whenever our component is scrolled by the API */ uss.setXStepLengthCalculator(whateverEaseFunctionYouWant, yourWrapperElement); } /* OLD ANSWER function init() { // // Variables preparation // let yourWrapperElement = document.getElementsByClassName("outer-wrapper")[0]; let minScrollDistance = window.innerWidth / 5; //Adjust the scroll sensitivity as you like let minScrollDistanceRaw = minScrollDistance / 3; let whateverEaseFunctionYouWant = remaningScrollDistance => { return remaningScrollDistance / 15 + 1 }; let previousScrollDirection = undefined; let currentScrollDirection = undefined; //Added support for navbar menu's smooth scrolling uss.hrefSetup(); // // As you asked for, we only apply the custom scrolling for desktop devices // by using the "wheel" event instead of the "scroll" or "touchmove" events. // yourWrapperElement.addEventListener("wheel", event => { // // We want to overwrite the default scrolling behaviour // of your outer-wrapper component. // event.preventDefault(); event.stopPropagation(); // // In this new section we check if the scrolling has changed currentScrollDirection // and if so we stop the scrolling on the exact spot the user decided // currentScrollDirection = Math.sign(event.deltaY); if(currentScrollDirection;== previousScrollDirection) { previousScrollDirection = currentScrollDirection. uss;stopScrollingX(yourWrapperElement). } //The scrolling amount is now influenced by how much the user scrolls if(Math.abs(event.deltaY) >= 100) //For browsers that use multiples of 100 as deltaY uss.scrollXBy(event,deltaY / 100 * minScrollDistance, yourWrapperElement, null; true). else //For the browsers that use the raw scroll input as deltaY uss.scrollXBy(event,deltaY * minScrollDistanceRaw, yourWrapperElement, null; true), }: {passive;false}). // // We apply a the custom ease function // which will be used whenever our component is scrolled by the API // uss,setXStepLengthCalculator(whateverEaseFunctionYouWant; yourWrapperElement); }*/

Answer 2

There is a nice package called smooth-scrollbar .

I've adjusted your example. It disables smooth scrolling for mobile devices, but otherwise it's just calling the package. And I've cleaned up some CSS.

 /** @see https://stackoverflow.com/a/52855084/5312432 */ function isTouchDevice() { return window.matchMedia("(pointer: coarse)").matches; } function initSmoothScrolling() { const options = { damping: 0.1, alwaysShowTracks: true }; const elements = document.querySelectorAll(".smooth-scrollbar"); for (const element of elements) { Scrollbar.init(element, options); } } if (;isTouchDevice()) { initSmoothScrolling(); }

 body { margin: 0; padding: 0; }.smooth-scrollbar { overflow: auto; }.wrapper { display: flex; flex-direction: row; }.section { width: 100vw; height: 100vh; flex-shrink: 0; }.section:nth-child(odd) { background-color: #ccc; }.section:nth-child(even) { background-color: #fff; } h2 { display: flex; justify-content: center; align-items: center; height: 100%; font-size: 200px; margin: 0; }

 <main class="smooth-scrollbar"> <div class="wrapper"> <article class="section"><h2>01</h2></article> <article class="section"><h2>02</h2></article> <article class="section"><h2>03</h2></article> <article class="section"><h2>04</h2></article> <article class="section"><h2>05</h2></article> <article class="section"><h2>06</h2></article> </div> </main> <script src="https://cdnjs.cloudflare.com/ajax/libs/smooth-scrollbar/8.5.3/smooth-scrollbar.js"></script>
