I am too late for this question but just add following sentence to css will make your scroll bar hidden
我回答这个问题为时已晚，但只需在 css 中添加以下句子即可隐藏滚动条
.element::-webkit-scrollbar { width: 0 !important }
where .element is a class of the div which has scroll bar
其中 .element 是具有滚动条的 div 类

仅 CSS 解决方案
<div id="container"> <--your code goes here--> </div>
#container{
height: 100% !important;
width: 100% !important;
overflow: hidden !important;
}
#chatlist{
width: 100% !important;
height: 99% !important;
overflow: auto !important;
padding-right: 15px !important;
}
html, body{
height: 99% !important;
border: 1px solid red;
overflow:hidden !important;

You can try jQuery Scrollbarwhich uses native scrollbar that are hidden with negative margins. Scrollbars are fully CSS customizable, so you can just hide them with display:noneif you don't need them visible. Mouse wheel scroll, trackpads and touch scroll will continue working.
您可以尝试使用使用负边距隐藏的本机滚动条的jQuery 滚动条。滚动条是完全 CSS 可定制的，因此display:none如果您不需要它们可见，您可以将它们隐藏起来。鼠标滚轮滚动、触控板和触摸滚动将继续工作。

Demo Fiddle
演示小提琴
Why not contain the scrollable element and push the scrollbar out of view? At some point the container will need its height constrained however.
为什么不包含可滚动元素并将滚动条推出视图？然而，在某些时候容器将需要其高度限制。
#chatlist {
width: 500px;
height: 300px;
border: 1px solid black;
overflow: hidden;
}
#chatlist ul {
height: 100%;
width: 520px;
overflow-y: scroll;
}
