技術標籤：vuevuejs

效果就是顯示某個數值不是直接顯示，而是從0開始滾動，直到為那個數值時停止滾動
1、新建數字滾動元件：test.vue檔案

<template>
	<div class="number-grow-warp">
		<span ref="numberGrow" :data-time="time" class="number-grow" :data-value="value">0</span>
	</div>
<
 
/template>
 
<script>
export default {
  props: {
    time: {
      type: Number,
      default: 2
    },
    value: {
      type: Number,
      default: 720000
    }
  },
  methods: {
    numberGrow (ele) {
      let _this = this
 
      let step = (_this.value * 10) / (_this.time * 1000)
      let current =
 
 0
      let start = 0
      let t = setInterval(function () {
        start += step
        if (start > _this.value) {
          clearInterval(t)
          start = _this.value
          t = null
        }
        if (current === start) {
          return
        }
        current = start
        ele.
 
innerHTML = current.toString().replace(/(\d)(?=(?:\d{3}[+]?)+$)/g, '$1,')
      }, 10)
    }
  },
  mounted () {
    this.numberGrow(this.$refs.numberGrow)
  }
}
</script>
 
<style>
.number-grow-warp{
  transform: translateZ(0);
}
.number-grow {
  font-family: Arial-BoldMT;
  font-size: 64px;
  color: #ffaf00;
  letter-spacing: 2.67px;
  margin:110px 0 20px;
  display: block;
  line-height:64px;
}
</style>

2、頁面使用
先引入元件

然後註冊元件

export default {
	components: {
		NumberGrow
	}
};

使用

<NumberGrow :value="720000"></NumberGrow>
