最近项目里使用到了数字翻牌器，找了半天 根据素材自己改了一个，动态的翻牌器

第一步创建一个组件页面， 

思路：大概就是显示几位数，然后从0开始滚动到当前的数值的位置，在每一个位置都有0-9的数，然后就是往上滚动当前数值的次数到当前的数，话不多说上代码

<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>
export default {
  props: {
    // 显示的数字
    number: {
      type: Number,
    }, // 显示的长度
    length: {
      type: Number,
    },
  },
  data() {
    return {
      orderNum: ["0", "0", "0", "0", "0", "0", "0", "0"], // 默认总数
    };
  },
  mounted() {
    setTimeout(() => {
      this.toOrderNum(777777); // 这里输入数字即可调用
    }, 500);
  },
  watch: {
    number: {
      handler(val) {
        this.toOrderNum(val);
      },
      deep: true,
    },
  },
  methods: {
    // 设置文字滚动
    setNumberTransform() {
      const numberItems = this.$refs.numberItem; // 拿到数字的ref，计算元素数量 // eslint-disable-next-line no-restricted-globals
      const numberArr = this.orderNum.filter((item) => !isNaN(item));
      console.log(numberItems.length, numberArr); // 结合CSS 对数字字符进行滚动,显示数量
      for (let index = 0; index < numberItems.length; index += 1) {
        const elem = numberItems[index];
        elem.style.transform = `translate(-50%, -${numberArr[index] * 10}%)`;
      }
    }, // 处理总数字
    toOrderNum(num) {
      const numtext = num.toString();
      if (this.length) {
        if (numtext.length < this.length) {
          const numlist = `0${numtext}`; // 如未满固定数，添加"0"补位
          this.toOrderNum(numlist); // 递归添加"0"补位
        } else if (numtext.length === num.length) {
          this.orderNum = numtext.split(""); // 将其便变成数据，渲染至滚动数组
        }
      } else {
        this.orderNum = numtext.split("");
      } // 数字中加入逗号 // const length = numtext.length / 3; // let count = ''; // for (let i = 0; i < length; i += 1) { //   if (i === 0) { //     count += `${numtext.slice(i, i + 3)},`; //     console.log(count); //   } else if (i === length - 1) { //     count += numtext.slice(i * 3, i * 3 + 3); //     console.log(count); //   } else { //     count += `${numtext.slice(i * 3, i * 3 + 3)},`; //     console.log(count); //   } // } // this.orderNum = count.split('');
      this.setNumberTransform();
    },
  },
};
