The mobile terminal uses overflow-y: auto; You can scroll, but there is no scroll bar. How do you want it to be displayed?

  javascript, node.js

I don’t care, I want scroll bars! ! ! !

You can use css to make scroll bars appear.
The code is as follows:

.rows {
 height: 230px;
 overflow: hidden;
 overflow-y: auto;
 bracket
 .rows::-webkit-scrollbar-track-piece {
 background-color: rgba(0, 0, 0, 0);
 border-left: 1px solid rgba(0, 0, 0, 0);
 bracket
 .rows::-webkit-scrollbar {
 width: 5px;
 height: 13px;
 -webkit-border-radius: 5px;
 -moz-border-radius: 5px;
 border-radius: 5px;
 bracket
 .rows::-webkit-scrollbar-thumb {
 background-color: rgba(0, 0, 0, 0.5);
 background-clip: padding-box;
 -webkit-border-radius: 5px;
 -moz-border-radius: 5px;
 border-radius: 5px;
 min-height: 28px;
 bracket
 .rows::-webkit-scrollbar-thumb:hover {
 background-color: rgba(0, 0, 0, 0.5);
 -webkit-border-radius: 5px;
 -moz-border-radius: 5px;
 border-radius: 5px;
 bracket
