vue幻灯片组件(一页多图)

加班到类似，就不一一介绍了，话不多说，直接上代码

<template>
  <div class="slider-body" ref="body">
    <div class="toLeft" @click="toLeft">
      <a-icon type="left"></a-icon>
    </div>
    <div class="slide-content" ref="content">
      <!-- 就突出一个套娃 -->
      <div
        class="slide-chunk"
        v-for="(chunk, chunkindex) in Img_arr"
        :key="chunkindex"
        :style="chunk.length == 1 ? 'justify-content:center' : ''"
      >
        <el-image v-for="(item, index) in chunk" fit="cover" :src="img_url + item.filePath" :key="index"> </el-image>
      </div>
