效果图：

此篇文章用的是vue+animejs实现的效果，对动画有兴趣的小伙伴们可以学习下，而且animejs的官方文档写的很好！！👍

其实这个效果是仿照其它网站上的，但是别人用的是canvas画布，而且感觉代码还有点多，所以就自己动手仿写了一个，效果差不多~~~~😁

代码如下：

<template>
  <div class="overall">
    <div class="box">
      <span class="dot" v-for="i in 250" :key="i"></span>
      <span class="text" @click="clickButton()">button</span>
    </div>
  </div>
</template>

<script>
import anime from "animejs/lib/anime.es.js";
export default {
  data() {
    return {};
  },

    // anime({

    //   ],
    //   delay: anime.stagger(100, { grid: [25, 10], from: "center" }),
    //   duration: 500,
