### 代码如下
直接复制进去就可以用了
```
 
 <template>
    <div class="chartNum">
      <div class="box-item">
        <li :class="{ 'number-item': !isNaN(item), 'mark-item': isNaN(item) }" v-for="(item, index) in orderNum" :key="index">
          <span v-if="!isNaN(item)">
            <i ref="numberItem">0123456789</i>
          </span>
          <span class="comma" v-else>{{ item }}</span>
        </li>
      </div>
    </div>
  </template>
  
  <script>

    },
    mounted() {
      let val = 12654
      setInterval(() => {
  
        this.toOrderNum(val) // 这里输入数字即可调用
        val = val + 10
      }, 1000);
    },
    methods: {
      // 设置文字滚动
      setNumberTransform() {

        for (let index = 0; index < numberItems.length; index++) {
          const elem = numberItems[index]
          elem.style.transform = `translate(-50%, -${numberArr[index] * 10}%)`
        }
      },
      // 处理总订单数字
      toOrderNum(num) {
        num = num.toString()

          this.$message.warning('总量数字过大')
