需求
ts
// 封装数据
const medicalData = [
{ labl_name_chn: "医疗机构代码", category: "医疗机构", list_name_chn: "基本信息" },
{ labl_name_chn: "统一社会信用代码", category: "医疗机构", list_name_chn: "基本信息" },
{ labl_name_chn: "医疗机构名称", category: "医疗机构", list_name_chn: "基本信息" },
{ labl_name_chn: "医疗机构简称", category: "医疗机构", list_name_chn: "基本信息" },
{ labl_name_chn: "主要负责人", category: "医疗机构", list_name_chn: "基本信息" },
// ... 其他数据项
{ labl_name_chn: "信用等级名称", category: "医疗机构", list_name_chn: "基本信息" },
{ labl_name_chn: "上级医疗机构代码", category: "医疗机构", list_name_chn: "基本信息" },
{ labl_name_chn: "机构性质", category: "医疗机构", list_name_chn: "基本信息" },
];ts
const ds = [
{
obj_id: "1",
code: null,
list_id: "11111111111111111111",
poolarea_no: "370100",
labl_id: "11111111111111111110",
labl_name: "MedicalIinstitutionCode",
labl_name_chn: "医疗机构代码",
col_name: "MedicalIinstitutionCode",
list_name_chn: "基本信息",
updt_frqu: null,
data_ymd: null,
datatype: "String",
act_stas: "1",
data_fmt: null,
},
];将 medicalData 的 labl_name_chn 和 list_name_chn 属性循环放进 ds 对应的属性中。用数组的 map 方法
