There is actually a pure javascript way to accomplish this without using setTimeout or requestAnimationFrame or jQuery   In short  find the element in the scrollView that you want to scroll to  and use scrollIntoView  el scrollIntoView  behavior  smooth      Here is a plunkr

This is a cross browser approach based on answers above  function scrollTo to  duration        if  duration  lt  0  return      var scrollTop   document body scrollTop   document documentElement scrollTop      var difference   to - scrollTop      var perTick   difference   duration   10       setTimeout function           scrollTop   scrollTop   perTick        document body scrollTop   scrollTop        document documentElement scrollTop   scrollTop        if  scrollTop     to  return        scrollTo to  duration - 10          10

Without JQuery code  Hope this will help you   function TopscrollTo     if window scrollY  0        setTimeout function            window scrollTo 0 window scrollY-30           TopscrollTo           100            call this TopscrollTo   function on button click event or on any other element event which you want

User · Answer

I see that most all of the above posts search for a button with javascript  This works  as long as you have only one button  I would recommend defining an  onclick  element inside the button  That  onclick  would then call the function causing it to scroll   If you do it like that  you can use more than one button  as long as the button looks something like this    lt button onclick  scrollTo document body  0  1250   gt To the top lt  button gt

Linear scrolling animation to bottom  Pure JS  no JQuery  Maybe my solution will be helpful for someone    let action count   8  let speed ms   15  let objDiv   document getElementsByClassName  js y5 area3   item 0    let scroll height   objDiv scrollHeight  let window height   objDiv offsetHeight   let scroll top   objDiv scrollTop  let need scroll top   scroll height - window height   if  scroll top  lt  need scroll top        let step   Math ceil  need scroll top - scroll top    action count        let scrollInterval   setInterval function                 scroll top    step          objDiv scrollTop   scroll top           if  scroll top  gt   need scroll top                        clearInterval scrollInterval                     speed ms       You can change variables action count  speed ms to configure scrolling animation on your taste

Another cross-browser approach based on above solution  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  amp  amp  window scrollY     start                element   document body              start   element scrollTop                    element scrollTop   position          if   i  i            if  elapsedTime  lt  duration                setTimeout function                     animateScroll elapsedTime                  increment                         animateScroll 0       The trick is to control the actual scroll change  and if it is zero  change the scroll element

PURE JAVASCRIPT SCROLLER CLASS  This is an old question but I thought I could answer with some fancy stuff and some more options to play with if you want to have a bit more control over the animation   Cross-browser   Copy Paste ready solution  You only need CSS and JS    3 animate modes    normal   linear  false       Customize your animation with available settings - make it snappy or fluent   Double click to skip animation   Every next single click adds initial speed   Stop scroll animation by draging down the scroll bar   Stop scroll animation by mouse wheel down   Animated button fade-in-out on scroll  Here it is a pure JS Class to take care of the scrolling for you   SEE DEMO AT CODEPEN OR GO TO THE BOTTOM AND RUN THE SINPET     ------------------- USE EXAMPLE
