Scrollbar平滑滚到指定位置

背景近期项目需求实现同一页面内进行导航跳转。一开始想到的是通过<a>标签描点定位，但是跳转效果不好，没有过渡的动画。后来试了scrollIntoView和scroll-behavior: smooth，一方面浏览器兼容性不好，另一方面无法控制过渡时间，当页面内容很多时，跳转太慢了。于是自己封装了一个跳转函数，支持立刻跳转、线性过渡、先快后慢（缓动）三种跳转方式，具体如下：演示https://theoxiong.github.io/s…安装方法$ npm install scroll-ease-efficient 使用// 支持 CommonJs/ES6/Script 三种引入// 1. CommonJs const { scrollTo } = require(‘scroll-ease-efficient’)// 2. ES6import { scrollTo } from ‘scroll-ease-efficient’// 3. Script<script type=“text/javascript” src=“scroll-ease-efficient/index.js”></script>// scrollable elementlet scrollEle = document.getElementById(‘id’)// 基本用法scrollTo(scrollEle, 500)// 指定过渡时间（单位ms）scrollTo(scrollEle, 500, { duration: 500})// 指定过渡动画效果, 支持’gradually’/’liner’/‘instant’scrollTo(scrollEle, 500, { timingFunction: ‘gradually’})// 指定过渡时间和动画效果scrollTo(scrollEle, 500, { timingFunction: ’liner’, duration: 500})// 指定缓动因子, 只对’gradually’方式有效scrollTo(scrollEle, 500, { timingFunction: ‘gradually’, factor: 6})函数说明function scrollTo (ele, pos, [options])ele < Dom> target scrollable elementpos <Number> specified the position which scroll tooptions <Object>timingFunction <String> specify velocity curve of scrolling, default value is ’linear’duration <Number> specify time of scrolling, default value is 1000factor <Number> specify the factor of gradually scrolling, it is only for gradually mode, should less then 100, and more then 1
