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
