css實現數字滾動特效 vue

1. 創建一個滾動組件

<template>
  <div class="qwNumBox" style="width: 36px;height:48px;">
    <div class="trasBox" :style="{ top:( -1 * value * 48) +'px' }">
      <div class="qwnum">0</div>
      <div class="qwnum">1</div>
      <div class="qwnum">2</div>
      <div class="qwnum">3</div>
      <div class="qwnum">4</div>
      <div class="qwnum">5</div>
      <div class="qwnum">6</div>
      <div class="qwnum">7</div>
      <div class="qwnum">8</div>
      <div class="qwnum">9</div>
    </div>
  </div>
</template>
<script>
  export default {
    props: {
      value: {
        type: Number,
        default() {
          return 0;
        }
      }
    }
  };
</script>
<style lang="scss">
  .qwNumBox + .qwNumBox {
    margin-left: 5px;
  }

  .qwNumBox {
    position: relative;
    display: inline-block;
    float: left;
    width: 36px;
    height: 48px;
    overflow: hidden;

    .trasBox {
      position: absolute;
      left: 0;
      top: 0;
      height: auto;
      width: 100%;
      transform-origin: 0 0;
      transition: top 0.8s;
    }

    .qwnum {
      width: 36px;
      height: 48px;
      line-height: 48px;
      background: rgba(72, 152, 241, 0.072);
      border: 1px solid rgba(72, 152, 241, .3); /*no*/
      border-radius: 6px;
      font-size: 36px;
      font-family: MicrosoftYaHei-Bold;
      font-weight: bold;
      color: #4898F1;
      text-align: center;
    }
  }
</style>

2. 根據數字長度循環出若干個該組件

<template v-for="(num,i) in getNumber(mark)">
  <numRun :value="parseInt(num)" :key="i"></numRun>
</template>
