技術標籤：vue的一些使用技巧htmlvue

將數字滾動單獨封裝成一個元件（如果專案中有規定的數字四個 0010 那麼傳入字串 ‘0010’就可以了）

<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>
export default {
  props: ["number"],
  data() {
    return {
      orderNum: [0, 0]
    };
  },
  watch:{
    number(val){
      console.log(val)
    }
  },
  created() {
    this.autoNumberFn(this.number);
  },
  methods: {
    autoNumberFn(num) {
      num = num.toString();
      this.orderNum = num.split(""); // 將其便變成資料，渲染至滾動陣列
      setTimeout(() => {
        this.setNumberTransform(); // 這裡輸入數字即可呼叫
      }, 500);
    },
    // 設定文字滾動
    setNumberTransform() {
      const numberItems = this.$refs.numberItem; // 拿到數字的ref，計算元素數量
      const numberArr = this.orderNum.filter(item => !isNaN(item));
      // 結合CSS 對數字字元進行滾動,顯示訂單數量
      for (let index = 0; index < numberItems.length; index++) {
        const elem = numberItems[index];
        elem.style.transform = `translate(-50%, -${numberArr[index] * 10}%)`;
      }
    }
  }
};
</script>

使用該元件

<template>
  <div>
     <auto-num :number="'0001'"></auto-num>
     <auto-num :number="12345"></auto-num>
  </div>
</template>
<script>
import AutoNum from "@/components/autoNum"; // 放置具體該元件的路徑位置
export default {
  name: "",
  components: {AutoNum},
  mounted() {
   
  },
  data() {
    return {
       
    };
  },
  methods: {
  
  }
};
</script>

<style lang="less" scoped>
