1.装依赖：npm install vue-count-to --save
2.引入：import CountTo from “vue-count-to”（可全局可单页面引入）
3.注册组件：在components中注册， components: {CountTo}

<template>
   <countTo :startVal='startVal' :endVal='endVal' :duration='2000'></countTo>
</template>

<script>
import CountTo from "vue-count-to"
export default {
  data () {
      return {
        startVal: 175,
        endVal: 1000
      }
    },
  components: {
    CountTo
  },
}
</script>

效果：
