我可以将属性放在数组中吗？

Question

我可以在数组中放入一些属性吗？

installments: string[];

我已经尝试过

installments: string[
    name: string;
    number: number
];

这是我的界面

export interface FiscalDocumentData {
    id: string;
    name: string;
    number: number;
    type: string;
    company: string;
    provider: string;
    value: string;
    paymentCondition: string;
    checker: string;
    approver: string;
    product: string;
    issueDate: string;
    status: string;
    activity: string;
    comments: string;
    installments: string[];
  }

这是一个模拟的例子

this.data = [{
      id: "de89cbb7-be6c-49e7-b3d5-6eef106cca7b",
      name: "Linet Fawdrie",
      number: 83,
      type: "Audi",
      company: "Gigazoom",
      provider: "Crooks LLC",
      value: "$1.56",
      paymentCondition: "Peso",
      checker: "Eziechiele Beecraft",
      approver: "Randy Libri",
      product: "NITROGLYCERIN",
      issueDate: "10/10/2018",
      status: "approved",
      activity: "Support",
      comments: "Lorem ipsum dolor sit amet",
      installments: ['1', '12-14-2019', '5000', 'Payed']
    }

Answer 1

我看到分期付款中的所有值都是字符串，因此您需要字符串数组

installments: string[];

您的模型应该看起来像

declare module namespace {

    export interface RootObject {
        id: string;
        name: string;
        number: number;
        type: string;
        company: string;
        provider: string;
        value: string;
        paymentCondition: string;
        checker: string;
        approver: string;
        product: string;
        issueDate: string;
        status: string;
        activity: string;
        comments: string;
        installments: string[];
    }

}

您可以使用 JSON2TS 进行检查

您不能向数组添加属性。只有对象。但是，如果您要用某种对象类型数组，请尝试以下操作：

installments: FiscalDocumentData[];
