将滚动条位置更改为固定

Question

I have the table with values more than 50 rows in my project. If I'm in the middle of the table I can't able to visible the scrollbar to scroll vertically.

As per the below example when I scroll the page down I want top vertical scrollbar to be fixed .

Anyone help to me achieve the scrollbar in fixed position when page scroll down. Let me know if you have any queries.

Before scroll:

After scroll:

 $(function(){ $(".wrapper1").scroll(function(){ $(".wrapper2") .scrollLeft($(".wrapper1").scrollLeft()); }); $(".wrapper2").scroll(function(){ $(".wrapper1") .scrollLeft($(".wrapper2").scrollLeft()); }); });

 .wrapper1, .wrapper2 { width: 800px; border: none 0px RED; overflow-x: scroll; overflow-y: hidden; } .wrapper1 { height: 20px; } .div1 { width: 1000px; height: 20px; } .div2 { width: 1000px; background-color: #88ff88; overflow: auto; }

Answer 1

你给wrapper1 class position: fixed property 你的问题就解决了

Answer 2

This is an example of scrolling using button. and Button can be positioned fixed so that it dont get scrolled

To scroll

document.querySelector('.wrapper2').scrollLeft += 40; //Right

document.querySelector('.wrapper2').scrollLeft -= 40; //left

To get smooth effect

scroll-behavior: smooth;

 const buttonRight = document.getElementById('scrollright'); const buttonLeft = document.getElementById('scrollleft'); buttonRight.onclick = function() { document.querySelector('.wrapper2').scrollLeft += 40; }; buttonLeft.onclick = function() { document.querySelector('.wrapper2').scrollLeft -= 40; };

 .wrapper1, .wrapper2 { width: 800px; border: none 0px RED; overflow-x: scroll; overflow-y: hidden; scroll-behavior: smooth; } .wrapper1 { height: 20px; } .div1 { width: 1000px; height: 20px; } .div2 { width: 1000px; background-color: #88ff88; overflow: auto; } #scrollleft { position: fixed; top: 50%; } #scrollright { position: fixed; top: 50%; right: 0; }
