基于VUE的可以滚动的横向时间轴

这个时间轴可以播放,翻篇,进行一些配置,

HTML:

      <div class="timeline-container">
        <div class="item">
          <div
            class="list"
            v-for="(item, index) in dataChart"
            :key="item.id"
            @click="go(index, '')"
            :style="{
                width: option.itemWidth ? `${option.itemWidth}px` : `100px`,
                height:option.itemHeight ? `${option.itemHeight}px` : `auto`,
                transform: `translateX(${translateNum}px)`,
            }"
          >
            <!-- 内容部分 -->
            <div
              :class="`text ${index === currentIndex?'active':''}`"
              :style="itemStyle(index)"
              :title="item.text"
            >
              {{ item.text }}
            </div>
          </div>
        </div>
        <!-- 播放/暂停,showPlayBtn:是否显示播放按钮 -->
        <div
          class="btn-play"
          @click="play"
          :style="btnStyle"
          v-if="option.showPlayBtn"
        >
          {{option.btnPlayName||'播放/暂停'}}
        </div>
      </div>
