使用 vanilla Javascript平滑滾動和動畫，無需jQuery

 // Get the el let topBtn = document.querySelector(".top-btn"); // On Click, Scroll to the page's top, replace 'smooth' with 'instant' if you don't want smooth scrolling topBtn.onclick = () => window.scrollTo({ top: 0, behavior: "smooth" }); // On scroll, Show/Hide the btn with animation window.onscroll = () => window.scrollY > 500 ? topBtn.style.opacity = 1 : topBtn.style.opacity = 0

 body { background-color: #111; height: 5000px; } .top-btn { all: unset; position: fixed; right: 20px; bottom: 20px; cursor: pointer; transform:scale(1.8); opacity: 0; transition: .3s; }

 <button class="top-btn">🔝</button>

Answer 33

function scrolltop() {

    var offset = 220;
    var duration = 500;

    jQuery(window).scroll(function() {
        if (jQuery(this).scrollTop() > offset) {
            jQuery('#back-to-top').fadeIn(duration);
        } else {
            jQuery('#back-to-top').fadeOut(duration);
        }
    });

    jQuery('#back-to-top').click(function(event) {
        event.preventDefault();
        jQuery('html, body').animate({scrollTop: 0}, duration);
        return false;
    });
}

Answer 34

以上所有答案均不適用於SharePoint 2016。

它必須像這樣完成： https : //sharepoint.stackexchange.com/questions/195870/

var w = document.getElementById("s4-workspace");
w.scrollTop = 0;

Answer 35

激活所有瀏覽器。 祝好運

var process;
        var delay = 50; //milisecond scroll top
        var scrollPixel = 20; //pixel U want to change after milisecond
        //Fix Undefine pageofset when using IE 8 below;
        function getPapeYOfSet() {
            var yOfSet = (typeof (window.pageYOffset) === "number") ? window.pageYOffset : document.documentElement.scrollTop;
            return yOfSet;
        }



        function backToTop() {
            process = setInterval(function () {
                var yOfSet = getPapeYOfSet();
                if (yOfSet === 0) {
                    clearInterval(process);
                } else {
                    window.scrollBy(0, -scrollPixel);
                }
            }, delay);
        }

Answer 36

嘗試這個

<script>
  $(function(){
   $('a').click(function(){
    var href =$(this).attr("href");
   $('body, html').animate({
     scrollTop: $(href).offset().top
     }, 1000)
  });
 });
 </script>

Answer 37

如果您想滾動到任何帶有 ID 的元素，請嘗試以下操作：

$('a[href^="#"]').bind('click.smoothscroll',function (e) {
    e.preventDefault();
    var target = this.hash;
    $target = $(target);
    $('html, body').stop().animate({
        'scrollTop': $target.offset().top
    }, 700, 'swing', function () {
        window.location.hash = target;
    });
});``

Answer 38

document.getElementById("elem").scrollIntoView();

Answer 39

如果您想為滾動動作設置動畫，則無需 javascript , event ！

CSS：

html {
    scroll-behavior: smooth;
}

HTML：

<html>
  <body>
     <a id="top"></a>
     <!-- your document -->
     <a href="#top">Jump to top of page</a>
  </body>
</html>

Answer 40

document.getElementsByTagName('html')[0].scrollIntoView({ behavior: "smooth" });

Answer 41

當頂部滾動頂部小於限制底部和底部到頂部滾動標題是粘性的。 下面參見小提琴示例。

var lastScroll = 0;

$(document).ready(function($) {

$(window).scroll(function(){

 setTimeout(function() { 
    var scroll = $(window).scrollTop();
    if (scroll > lastScroll) {

        $("header").removeClass("menu-sticky");

    } 
    if (scroll == 0) {
    $("header").removeClass("menu-sticky");

    }
    else if (scroll < lastScroll - 5) {


        $("header").addClass("menu-sticky");

    }
    lastScroll = scroll;
    },0);
    });
   });

Answer 42

只需嘗試，無需其他插件/框架

 document.getElementById("jarscroolbtn").addEventListener("click", jarscrollfunction); function jarscrollfunction() { var body = document.body; // For Safari var html = document.documentElement; // Chrome, Firefox, IE and Opera body.scrollTop = 0; html.scrollTop = 0; }

 <button id="jarscroolbtn">Scroll contents</button>

 html, body { scroll-behavior: smooth; }

Answer 43

最短的

location='#'

此解決方案是對pollirrata 答案的改進，但有一些缺點：無法平滑滾動和更改頁面位置，但最短

Answer 44

使用 AplineJS 和 TailwindCSS 返回頂部：

<button
    x-cloak
    x-data="{scroll : false}"
    @scroll.window="document.documentElement.scrollTop > 20 ? scroll = true : scroll = false"
    x-show="scroll" @click="window.scrollTo({top: 0, behavior: 'smooth'})"
    type="button"
    data-mdb-ripple="true"
    data-mdb-ripple-color="light"
    class="fixed inline-block p-3 text-xs font-medium leading-tight text-white uppercase transition duration-150 ease-in-out bg-blue-600 rounded-full shadow-md hover:bg-blue-700 hover:shadow-lg focus:bg-blue-700 focus:shadow-lg focus:outline-none focus:ring-0 active:bg-blue-800 active:shadow-lg bottom-5 right-5"
    id="btn-back-to-top"
    x-transition.opacity

Answer 45

用於滾動到頁面頂部的元素和元素

WebElement tempElement=driver.findElement(By.cssSelector("input[value='Excel']"));

            ((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", tempElement);

Answer 46

滾動到的一個簡單示例（使用 html 效率更高，但這里是如何使用 JavaScript 執行此操作）：

 const btn = document.querySelector('.btn'); btn.addEventListener('click',()=>{ window.scrollTo({ left: 0, top: 0, })}) window.addEventListener('scroll', function() { const scrollHeight = window.pageYOffset; if (scrollHeight > 500) { btn.classList.add('show-link'); } else { btn.classList.remove('show-link'); } });

 .section { padding-bottom: 5rem; height: 90vh; } .btn { position: fixed; bottom: 3rem; right: 3rem; background: blue; width: 2rem; height: 2rem; color: #fff; visibility: hidden; z-index: -100; } .show-link { visibility: visible; z-index: 100; } .title h2 { text-align: center; }

 <section class="section"> <div class="title"> <h2>Section One</h2> </div> </section> <section class="section"> <div class="title"> <h2>Section Two</h2> </div> </section> <section class="section"> <div class="title"> <h2>Section Three</h2> </div> </section> <a class="btn"> </a>

Answer 47

請檢查下面的代碼，肯定會有幫助。 :)

document.querySelector('.sample-modal .popup-cta').scrollIntoView(true);
document.querySelector('.sample-modal').style.scrollPadding = '50px'; //to move to the top when scrolled up.

Answer 48

使用簡單的 css 嘗試此解決方案只需將 css scroll-behavior:smooth放在html and body上，就像我在 css 中應用的那樣。 而已

 document.querySelector('a').onclick = function() { window.scrollTo(0,0) }

 html,body{ scroll-behavior: smooth; } a{ background-color: red; color:#fff; border-radius: 10px; margin:10px 0; display: inline-block; padding:10px 20px; }

我希望這會對你有很大幫助。 請讓我知道你的想法

Answer 49

有趣的是，其中大部分對我來說根本不起作用，所以我使用了 jQuery-ScrollTo.js：

wrapper.find(".jumpToTop").click(function() {
    $('#wrapper').ScrollTo({
        duration: 0,
        offsetTop: -1*$('#container').offset().top
    });
});

它奏效了。 $(document).scrollTop()返回0 ，而這個實際上起作用了。
