vue3 Element Plus 上传组件 before-upload 钩子函数不触发

需求

手动上传，限制文件不能超过100kb，文件数不能超过10个

代码

 // js
 let fileListData = ref([])
 
const generateCharts = () => {
  fileListData.value.length >1?router.push('/multi-comparison'):router.push('/single-comparison')
  // 应该是文件加类型的传递参数
}


const progress = (value,changeFileList) =>{
  // 限制
  const isLt10M = value.size / 1024 < 1000;
  if (!isLt10M) {
    ElMessage.error('上传文件大小不能超过 1000kb!');
    changeFileList.splice(-1,1)
    return false;
  }
  // 更改文件数量
  excelMetadataStore.update_file_num(fileListData.value.length+1)

}

const handleRemove = (files) =>{
  console.log(fileListData,'==fileListData==');
  excelMetadataStore.update_file_num(fileListData.value.length-1)
}

const exceed = () =>{
  ElMessage.error('上传文件数量不能超过10个!');
}
