el-upload图片上传（上传一张之后按钮隐藏，照片删除按钮出现）

直接上代码

<template>
  <!--el-upload里面绑定一个占位class：设置隐藏-->
  <div class="hello">
    <el-upload
      ref="pictureUpload"
      action="#"
      list-type="picture-card"
      :auto-upload="false"
      :class="{ hide: hideUpload }"
      :on-change="handleChange"
    >
      <i slot="default" class="el-icon-plus" />
      <div slot="file" slot-scope="{ file }">
        <img class="el-upload-list__item-thumbnail" :src="file.url" alt="">
        <span class="el-upload-list__item-actions">
