在vue-cli中使用iview组件上传多个文件的功能

思路：创建一个数组 把需要上传的文件 push到这个数组里面
需求：

点击提交按钮把上传后得文件URL地址当做参数传给后台；多个文件使用逗号隔开

样式随便写的，自己做的demo

html代码

<template>
  <div>
    <Upload
      ref="upload"
      multiple  //支持多选文件
      name="files"  //上传接口的参数
      :before-upload="handleUpload"  //上传之前调用
      :on-success="uploadSuccess"  //上传成功调用
      :on-error="uploadError"  //上传失败调用
      :format="['docx','doc','txt', 'pdf']"  文件上传的格式
      :on-format-error="handleFormatError"   //文件格式错误调用
      action="http://192.10.78.68:8060/FH_AM6/api/fileUpload/upload"  //上传的接口地址
    >
      <Button icon="ios-cloud-upload-outline">上传</Button>
    </Upload>
    <Button type="primary" @click="issues" class="issues">提交</Button>
  </div>
</template>

js代码

<script>
    export default {
        name: "ces",
      data(){
          return{
            uploadList: [],

      },
      created() {

      //监听attachments对象的值，有新值添加进一个数组
      watch: {

            for(let j = 0;j<this.uploadList.length;j++){
              urlList.push(this.uploadList[j].url)

            this.attachments = urlList.join(",")
