react怎么实现滚动条

render() {
const translateDistancePercentage = '33.33333333333333'; // 滚动条滚动百分比
console.log('滚动条滚动百分比' + translateDistancePercentage);
return (
// 滚动条
<div className="scrollBar" style={{ 'backgroundImage': `url(首页/滚动条外壳.png)` }}>
    <div className="scrollBarHousing">
        <span className="insideScrollBar" style={{ 'transform': `translateX(${translateDistancePercentage}%)`, 'backgroundImage': `url(首页/滚动条内里.png)` }}></span>
    </div>
</div>
)
}

 .scrollBar {
 /** 滚动条宽度 */
    width: 362px;
    height: 12px;
    left: 0px;
    top: 36px;
    position: absolute;
    opacity: 0.7;
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;
    .scrollBarHousing {
      width: 100%;
      height: 100%;
      left: 0px;
      top: 0px;
      position: absolute;
      border-radius: 60px;
      /** 下面这个很关键喔 */
      overflow: hidden;
      .insideScrollBar {
        width: 100%;
        height: 100%;
        /** 让滚动条内里一来就先位于滚动条外最左侧 */
        left: -362px;
        top: 0px;
        position: absolute;
        border-radius: 60px;
        background-position: center;
        background-repeat: no-repeat;
