类型中缺少属性“0” [英] Property '0' is missing in type

问题描述

我有这样的界面

export interface Details {
    Name: [{
        First: string;
        Last: string;
    }];
}   

我有一个可观察的配置变量

I have a observable config variable

Configuration: KnockoutObservable<Details> = ko.observable<Details>();

我想在构造函数中为它赋值如下 -

and I would like to assign it a value in the constructor as follows -

config = {
         Name: [{
               First: "ABC",
               Last: "DEF"
            },
            {
               First: "LMN",
               Last: "XYZ"
            }]
        };

this.Configuration(config);

我收到错误：

财产类型'名称'不兼容，属性'0'缺少
类型。

Types of property 'Name' is incompatible and property '0' is missing in type.

输入'{First：串;最后：字符串; } []'不能赋值为'[{
First：string;最后：字符串; }]'

Type '{ First:string; Last:string; }[]' is not assignable to type '[{ First: string; Last:string; }]'

我无法控制更改界面，因为它正在其他地方使用。初始化此配置变量的正确方法是什么？

I don't have control on changing the interface as it is being used elsewhere. What is the correct way to initialize this config variable ?

提前致谢。

推荐答案

我遇到了同样的问题，并通过将界面更改为：

I came across the same issue and got around it by changing the interface to:

    interface Details {
        Name: {
            First: string;
            Last: string;
        }[];
    }

我知道您可能不希望界面发生变化，但希望这有助于任何人在这种情况下。

I know you may not want the interface changed but hope this helps for anyone that is in this situation.
