没有JQuery代码，希望这将帮助你。

function TopscrollTo() {
if(window.scrollY!=0)
{
    setTimeout(function() {
       window.scrollTo(0,window.scrollY-30);
        TopscrollTo();
    }, 100);
   }
}

在按钮单击事件或任何其他你想要的元素/事件上调用这个TopscrollTo()函数。

还有一种方法是使用window.scrollBy

JSFiddle

function scroll(pxPerFrame, duration) { if (!pxPerFrame || !duration) return; const end = new Date().getTime() + duration; step(); function step() { window.scrollBy(0, pxPerFrame); if (new Date().getTime() < end) { window.setTimeout(step, 1000 / 60); } else { console.log('done scrolling'); } } } body { width: 200px; } <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

看来已经有很多解决方案了。不管怎样，这是另一个，使用简化方程。

// first add raf shim
// http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/
window.requestAnimFrame = (function(){
  return  window.requestAnimationFrame       ||
          window.webkitRequestAnimationFrame ||
          window.mozRequestAnimationFrame    ||
          function( callback ){
            window.setTimeout(callback, 1000 / 60);
          };
})();

// main function
function scrollToY(scrollTargetY, speed, easing) {
    // scrollTargetY: the target scrollY property of the window
    // speed: time in pixels per second
    // easing: easing equation to use

    var scrollY = window.scrollY || document.documentElement.scrollTop,
        scrollTargetY = scrollTargetY || 0,
        speed = speed || 2000,
        easing = easing || 'easeOutSine',
        currentTime = 0;

    // min time .1, max time .8 seconds
    var time = Math.max(.1, Math.min(Math.abs(scrollY - scrollTargetY) / speed, .8));

    // easing equations from https://github.com/danro/easing-js/blob/master/easing.js
    var easingEquations = {
            easeOutSine: function (pos) {
                return Math.sin(pos * (Math.PI / 2));
            },
            easeInOutSine: function (pos) {
                return (-0.5 * (Math.cos(Math.PI * pos) - 1));
            },
            easeInOutQuint: function (pos) {
                if ((pos /= 0.5) < 1) {
                    return 0.5 * Math.pow(pos, 5);
                }
                return 0.5 * (Math.pow((pos - 2), 5) + 2);
            }
        };

    // add animation loop
    function tick() {
        currentTime += 1 / 60;

        var p = currentTime / time;
        var t = easingEquations[easing](p);

        if (p < 1) {
            requestAnimFrame(tick);

            window.scrollTo(0, scrollY + ((scrollTargetY - scrollY) * t));
        } else {
            console.log('scroll done');
            window.scrollTo(0, scrollTargetY);
        }
    }

    // call it once to get started
    tick();
}

// scroll it!
scrollToY(0, 1500, 'easeInOutQuint');

只做了这个javascript解决方案下面。

简单的用法:

EPPZScrollTo.scrollVerticalToElementById('wrapper', 0);

引擎对象(你可以摆弄过滤器，fps值):

};

实际上有一个纯javascript的方式来完成这个不使用setTimeout或requestAnimationFrame或jQuery。

简而言之，在scrollView中找到要滚动到的元素，并使用scrollIntoView

el.scrollIntoView({行为:“平滑”});

这是一个普朗克。

另一种基于上述解决方案的跨浏览器方法

function doScrollTo(to, duration) {
    var element = document.documentElement;

        var start = element.scrollTop,
        change = to - start,
        increment = 20,
        i = 0;

    var animateScroll = function(elapsedTime) {
        elapsedTime += increment;
        var position = easeInOut(elapsedTime, start, change, duration);
        if (i === 1 && window.scrollY === start) {
            element = document.body;
            start = element.scrollTop;
        }
        element.scrollTop = position;
        if (!i) i++;
        if (elapsedTime < duration) {
            setTimeout(function() {
                animateScroll(elapsedTime);
            }, increment);
        }
    };

    animateScroll(0);
}

诀窍在于控制实际的滚动变化，如果它为零，则更改滚动元素。
