怎么判断 element Upload 多文件上传完成

<template>
  <el-upload
    :action="uploadUrl"
    :on-success="handleSuccess"
    :on-exceed="handleExceed"
    :file-list="fileList"
    multiple>
    <el-button size="small" type="primary">点击上传</el-button>
  </el-upload>
</template>
 
<script>
export default {
  data() {
    return {
      uploadUrl: 'your-upload-url',
      fileList: [],
      allFilesUploaded: false
    };
  },
  methods: {
    handleSuccess(response, file, fileList) {
      // 单个文件上传成功后的回调
      // 检查所有文件是否已上传完毕
      if (this.fileList.length === fileList.length) {
        this.allFilesUploaded = true;
        // 执行其他逻辑，例如关闭上传窗口或提示用户
      }
    },
    handleExceed(files, fileList) {
      // 当超出最大上传数量时的回调
      // 可以用来处理超出文件数量的逻辑
    }
  }
};
</script>
