Typescript lib.d.ts中的类型脚本定义

请看代码

为什么它不能识别

IDBKeyRange

在

lib.d.ts

中，我看到了这些定义

interface IDBKeyRange {
    upper: any;
    upperOpen: boolean;
    lower: any;
    lowerOpen: boolean;
    bound(lower: any, upper: any, lowerOpen?: boolean, upperOpen?: boolean): IDBKeyRange;
    only(value: any): IDBKeyRange;
    lowerBound(bound: any, open?: boolean): IDBKeyRange;
    upperBound(bound: any, open?: boolean): IDBKeyRange;
}
declare var IDBKeyRange: {
    prototype: IDBKeyRange;
    new (): IDBKeyRange;
}

这是lib.d.ts文件中的一个错误。你可以

interface IDBKeyRange {
    upper: any;
    upperOpen: boolean;
    lower: any;
    lowerOpen: boolean;
    bound(lower: any, upper: any, lowerOpen?: boolean, upperOpen?: boolean): IDBKeyRange;
    only(value: any): IDBKeyRange;
    lowerBound(bound: any, open?: boolean): IDBKeyRange;
    upperBound(bound: any, open?: boolean): IDBKeyRange;
}
declare var IDBKeyRange: {
    prototype: IDBKeyRange;
    new (): IDBKeyRange;
}
