vue3+ts 重复参数提取成方法多处调用以及字段无值时不传字段给后端

参数提取前的写法，此写法值为空的时候也会传空字段给后端

会把无值的空字段传给后端

修改后的写法，不会把没有值的字段传给后端

// 列表和导出需要传给后端的公共参数（加 || undefined即可过滤空字段）
const getCurentParam = () => {
  return {
    user_id: info.id || undefined,
    shop_id: state.shop_id || undefined,
    equipment_type: state.equipment_type || undefined,
    relate_type: state.relate_type || undefined,
    sdate: state.dateTime ? state.dateTime[0] : undefined,
    edate: state.dateTime ? state.dateTime[1] : undefined
  };
};

// 数据获取
const getTableData = async () => {
  state.loading = true;
  const { code, data, total } = (await xcx_user_sportlog({
    ...getCurentParam(),
    page: state.pageIndex,
    size: state.pageSize
  })) as HttpResponse;
  if (code == 200 && data) {
    let result = data || [];
    state.tableData = result;
    state.total = total;
    console.log("用户运动记录", result);
  }
  state.loading = false;
};

// 导出
const onExport = async () => {
  const res = (await export_sportlog(getCurentParam())) as HttpResponse;
  if (res.code == 200 && res?.url) {
    const link = document.createElement("a");
    link.href = res?.url;
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);
  } else {
    ElMessage.warning("暂无数据导出");
  }
};

只传有值的字段给后端
