ts踩坑记录

错误信息 TS7053

const person = {
    name: '张三',
    age: 10
};

function getValue(arg: string) {
    return person[arg];
}


 TS7053: Element implicitly has an 'any' type because expression of type 'string' can't be used to index type '{ isMobile: string; isUnion: string; isTelcom: string; no: s
tring; }'.

解决方法1：

在tsconfig.json中配置suppressImplicitAnyIndexErrors: true

{
    "compilerOptions": {
        "suppressImplicitAnyIndexErrors": true,
        ...
    },
    ...
}

解决方法2： 给person定义接口

const person = {
    name: '张三',
    age: 10
};

function getValue(arg: string) {
    interface IPerson {
        [key: string]: any
    }
    return (<IPerson>person)[arg];
}
