vue-quill-editor +elementUI实现图片上传，及删除图片，把服务器多余图片删除

实现思路：上传图片后，接口返回地址，把地址存数组，监听编辑器内容变化，比较图片数组，删除多余图片

在 Vue 项目中导入 @vueup/vue-quill

npm install @vueup/vue-quill

调用

  <editor v-model="form.activityContent" :min-height="300" />

回显

  <div style="width: 100% !important" class="htmlcont qi-container ql-snow">
     <div class="mag-content ql-editor" v-html="form.activityContent"></div>
  </div>
