之前有这样子的需求没有用第三方插件于是自己写一个简单的时间轴

时间轴滚动条并左右切换滚动条位置相对应移动

<div class="time-scrollbar">
        <div v-if="timeLineData.length>0" class="scrollbar-content">
          <div class="arrow" @click="clickLeft"> <el-icon :size="40"><ArrowLeft /></el-icon></div>
          <el-scrollbar ref="timeScrollbarRef" @scroll="scrollChange"  always >
            <TimeLine ref="timeLineRef" id="timeLineId" class="time-line" direction="vertical" :stripe="true" sizeIcon="large" 
            :timelineList="timeLineData" :hollowIcon="true" :hasNameCenter="false"/>
          </el-scrollbar>
          <div class="arrow" @click="clickRight"><el-icon :size="40"><ArrowRight /></el-icon></div>
        </div>
        <div v-else class="text-info">暂无数据</div>
   </div>

const clickLeft = () => {
  if(start.value > 0) {
    start.value = start.value-1398
    end.value = end.value-10
    timeScrollbarRef.value.scrollTo(start.value, end.value)
    // 点击更改数据
     // page.value = page.value >=1? 1: page.value-1 
     // getTimeLineData()
  }
}
const scrollChange = (scrollData: any) => {
  start.value = scrollData.scrollLeft
}
const clickRight = () => {
  const contentWidth = document.getElementById('timeLineId')?.offsetWidth as number
  if((end.value + 1398) < contentWidth) {
    start.value = start.value+1398
    end.value = end.value+10
    timeScrollbarRef.value.scrollTo(start.value, end.value)
  }
  //  点击更改数据
  // page.value = page.value+1 
  // getTimeLineData()
}

//TimeLine页面
