將滾動條位置更改為固定

Question

我的項目中有超過 50 行的值的表。 如果我在表格中間，則無法看到滾動條以垂直滾動。

根據下面的示例，當我向下滾動頁面時，我希望頂部垂直滾動條是固定的。

當頁面向下滾動時，任何人都可以幫助我實現固定位置的滾動條。 如果您有任何疑問，請告訴我。

滾動前：

滾動后：

 $(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

你給wrapper1 class position: fixed property 你的問題就解決了

Answer 2

這是使用按鈕滾動的示例。 並且 Button 可以固定定位，這樣它就不會滾動

滾動

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

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

獲得流暢的效果

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; }
