主从表结构#xff0c;有时为了方便数据呈现#xff0c;在UI上不显示从表资料#xff0c;那么需要动态把从表的资料加载到主表的固定栏位上。
例如#xff1a;主表是人员信息#xff0c;从表是银行卡信息#xff0c;一个人在同一家银行可能有多张银行卡有时为了方便数据呈现在UI上不显示从表资料那么需要动态把从表的资料加载到主表的固定栏位上。
例如主表是人员信息从表是银行卡信息一个人在同一家银行可能有多张银行卡且一个人可能在多家银行开户。
How to implement?
1. Provided data list of person and bank account informaciton
a. Person information
personData: any[] [{key: 1,name: John Brown,age: 32,address: New York No. 1 Lake Park},{key: 2,name: Jim Green,age: 42,address: London No. 1 Lake Park},{key: 3,name: Joe Black,age: 32,address: Sidney No. 1 Lake Park}];
b. Bank list banks [{ code: icbc, name: 工行 },{ code: abc, name: 农行 },{ code: ccb, name: 建行 },{ code: bocom, name: 交行 },{ code: boc, name: 中行 }]; c. Bank account list bankAccounts: BankAccount[] [{ key: 1, account: 1-工行001, bank: icbc },{ key: 2, account: 2-交行001, bank: bocom },{ key: 3, account: 3-建行001, bank: ccb },{ key: 3, account: 3-农行001, bank: abc },{ key: 1, account: 1-农行001, bank: abc },{ key: 1, account: 1-农行002, bank: abc },{ key: 2, account: 2-工行001, bank: icbc },{ key: 1, account: 1-工行002, bank: icbc }];
2. Interface
a. Person
interface Person {key: string;name: string;age: number;address: string;icbc: string;abc: string;ccb: string;bocom: string;boc: string;
}b. Bank account
interface BankAccount {key: string;account: string;bank: string;
}
3. Implementation method
const refList this.bankAccounts;const refType this.banks;// 循环主表for (let item of this.personData) {//循环从表需显示在主表呈现的类型refType.forEach(typ {const accoutsOfBank refList.filter(o o.key item.key o.bank typ.code); //[{}]let accounts ;// 按从表类型把资料合并for (const element of accoutsOfBank) {accounts ${element.account};;}// 根据从表类型把合并的资料更新至主表固定栏位上switch (typ.code) {case icbc:item.icbc accounts;break;case abc:item.abc accounts;break;case ccb:item.ccb accounts;break;case bocom:item.bocom accounts;break;case boc:item.boc accounts;break;default:break;}});}
