我设置了一个模块滚动元素npm安装滚动元素。它的工作原理如下：

import { scrollToElement, scrollWindowToElement } from 'scroll-element'

/* scroll the window to your target element, duration and offset optional */
let targetElement = document.getElementById('my-item')
scrollWindowToElement(targetElement)

/* scroll the overflow container element to your target element, duration and offset optional */
let containerElement = document.getElementById('my-container')
let targetElement = document.getElementById('my-item')
scrollToElement(containerElement, targetElement)

在以下SO帖子的帮助下编写：

没有jquery的元素的顶部偏移量不带jquery的滚动条动画

代码如下：

export const scrollToElement = function(containerElement, targetElement, duration, offset) {
  if (duration == null) { duration = 1000 }
  if (offset == null) { offset = 0 }

  let targetOffsetTop = getElementOffset(targetElement).top
  let containerOffsetTop = getElementOffset(containerElement).top
  let scrollTarget = targetOffsetTop + ( containerElement.scrollTop - containerOffsetTop)
  scrollTarget += offset
  scroll(containerElement, scrollTarget, duration)
}

export const scrollWindowToElement = function(targetElement, duration, offset) {
  if (duration == null) { duration = 1000 }
  if (offset == null) { offset = 0 }

  let scrollTarget = getElementOffset(targetElement).top
  scrollTarget += offset
  scrollWindow(scrollTarget, duration)
}

function scroll(containerElement, scrollTarget, duration) {
  let scrollStep = scrollTarget / (duration / 15)
  let interval = setInterval(() => {
    if ( containerElement.scrollTop < scrollTarget ) {
      containerElement.scrollTop += scrollStep
    } else {
      clearInterval(interval)
    }
  },15)
}

function scrollWindow(scrollTarget, duration) {
  let scrollStep = scrollTarget / (duration / 15)
  let interval = setInterval(() => {
    if ( window.scrollY < scrollTarget ) {
      window.scrollBy( 0, scrollStep )
    } else {
      clearInterval(interval)
    }
  },15)
}

function getElementOffset(element) {
  let de = document.documentElement
  let box = element.getBoundingClientRect()
  let top = box.top + window.pageYOffset - de.clientTop
  let left = box.left + window.pageXOffset - de.clientLeft
  return { top: top, left: left }
}

我编写了一个通用函数，可以滚动到jQuery对象、CSS选择器或数值。

示例用法：

// scroll to "#target-element":
$.scrollTo("#target-element");

// scroll to 80 pixels above first element with class ".invalid":
$.scrollTo(".invalid", -80);

// scroll a container with id "#my-container" to 300 pixels from its top:
$.scrollTo(300, 0, "slow", "#my-container");

函数的代码：

/**
* Scrolls the container to the target position minus the offset
*
* @param target    - the destination to scroll to, can be a jQuery object
*                    jQuery selector, or numeric position
* @param offset    - the offset in pixels from the target position, e.g.
*                    pass -80 to scroll to 80 pixels above the target
* @param speed     - the scroll speed in milliseconds, or one of the
*                    strings "fast" or "slow". default: 500
* @param container - a jQuery object or selector for the container to
*                    be scrolled. default: "html, body"
*/
jQuery.scrollTo = function (target, offset, speed, container) {

    if (isNaN(target)) {

        if (!(target instanceof jQuery))
            target = $(target);

        target = parseInt(target.offset().top);
    }

    container = container || "html, body";
    if (!(container instanceof jQuery))
        container = $(container);

    speed = speed || 500;
    offset = offset || 0;

    container.animate({
        scrollTop: target + offset
    }, speed);
};

截至2019年的更新答案：

$('body').animate({
    scrollTop: $('#subject').offset().top - $('body').offset().top + $('body').scrollTop()
}, 'fast');

要显示整个元素（如果可以使用当前窗口大小）：

var element       = $("#some_element");
var elementHeight = element.height();
var windowHeight  = $(window).height();

var offset = Math.min(elementHeight, windowHeight) + element.offset().top;
$('html, body').animate({ scrollTop: offset }, 500);

在找到了让我的代码工作的方法之后，我想我应该把事情弄清楚一点：用于：

$('html, body').animate({
   scrollTop: $("#div1").offset().top
}, 2000);

您需要在页面顶部，因为$（“#div1”）.offset（）.top将为您滚动到的不同位置返回不同的数字。如果您已经滚动到顶部，则需要指定确切的pageY值（请参阅此处的pageY定义：https://javascript.info/coordinates).

现在，问题是计算一个元素的pageY值。下面是滚动容器为主体的示例：

function getPageY(id) {
    let elem = document.getElementById(id);
    let box = elem.getBoundingClientRect();
    var body = document.getElementsByTagName("BODY")[0];
    return box.top + body.scrollTop; // for window scroll: box.top + window.scrollY;
}

即使您滚动到某个位置，上面的函数也会返回相同的数字。现在，要滚动回该元素：

$("html, body").animate({ scrollTop: getPageY('div1') }, "slow");

这是我使用通用类选择器抽象ID和href的方法

$（函数）{//可在任何地方使用的通用选择器$（“.js滚动到”）.click（函数（e）{//动态获取hrefvar destination=$（this）.attr（'href'）；//阻止href=“#”链接更改URL哈希（可选）e.预防违约（）；//动画滚动到目的地$（'html，body'）.animate({scrollTop:$（destination）.offset（）.top}, 500);});});<!-- 固定导航菜单示例--><ul class=“nav”><li><a href=“#section-1”class=“nav item js scroll to”>项目1</a></li><li><a href=“#section-2”class=“nav item js scroll to”>项目2</a></li><li><a href=“#section-3”class=“nav item js scroll to”>项目3</a></li></ul>
