May I ask the upoad question about element?

<template>
  <div id="app">
    <div
      id="one"
      v-for="(item,idx) in fileList"
      :key="idx"
    >
      <el-upload
        class="upload-demo"
        action="https://jsonplaceholder.typicode.com/posts/"
        multiple
        :limit="3"
        :file-list="item.file"
        :on-success="success(idx)"
      >
        <el-button
          size="small"
          type="primary"
        ></el-button>
      </el-upload>
      <el-checkbox-group v-model="item.checkList">
        <el-checkbox label=" A"></el-checkbox>
        <el-checkbox label=" B"></el-checkbox>
        <el-checkbox label=" C"></el-checkbox>
        <el-checkbox label=""></el-checkbox>
        <el-checkbox label=""></el-checkbox>
      </el-checkbox-group>
    </div>
    <el-button @click="add">PPPPPP</el-button>
    <div>{{ fileList }}</div>
  </div>
</template>

<script>
export default {
  name: "app",
  data() {
    return {
      fileList: [
        {
          file: [],
          checkList: []
        }
      ]
    };
  },
  methods: {
    add() {
      this.fileList.push({
        file: [],
        checkList: []
      });
    },
    success(idx) {
      this.fileList[idx].file = fileList
    }
  }
};
</script>

<style>
-sharpapp {
  width: 200px;
  margin: 0 auto;
}
-sharpone {
  border: 1px solid red;
}
</style>

this is a simple demo, I wrote that tortured me all afternoon.
I meant that PP+ loops one div at a time. Each div can then upload a different file and select the corresponding selection box.
but ask why the value of the selection box can be placed normally in fileList, while the uploaded file information is not available.
can you tell me how to get the sharp-sharp-sharp problem description

el-upload : the parameter action indicates that the destination URL, for upload may not be used if it has its own server. : http-request= "upload" parameter indicates upload operation
define upload- in < script > < / script > upload (param) {console.log (param.file)} you can see the file information you uploaded
