效果

点击左侧边栏，右侧会定位到对应内容；
右侧滑动，左侧也会显示对应的高亮；
也就是左右联动的效果

项目场景

tocc-app 应急巡检
传入数据:

左侧点击，右侧滚动到对应位置

点击左侧导航条，就计算出右侧要的

      toggleActive(index) {
        this.isSidebarClick = true
        this.scActiveIndex = index
        // .map返回数组，里面的元素是每个对象中scContentData的长度  [6,6,6,6,6]
        // 然后 .reduce 来求和 计算总的长度
        this.scContentScrollTop =
          this.scDataList
            .slice(0, index)
            .map((item) => item.scContentData.length)
            .reduce((total, length) => total + length, 0) *
            41 +
            // 因为右边除了数据，还要展示小标题，所以要再加上前面的标题
          this.scDataList.slice(0, index).length * 41
      },
