typescript - typescript 参数不正确

Question

我正在尝试将此 TypeScript 数组传递给一个函数。我已经尝试了多种参数类型来进行编译，但它们似乎都不起作用。这是数组:

var driverTally = [
                    { driver: 'driver1', numEscorts: 0},
                    { driver: 'driver2', numEscorts: 0},
                    { driver: 'driver3', numEscorts: 0} 
                ];

doStuff(driverTally : Array<[string,number]>){ ... }

编译器一直说:“'{ driver: string; numEscorts: number; }[]' 类型的参数不能分配给 '[string, number][]' 类型的参数。

Answer 1

如果不确定类型，可以使用 any，

doStuff(driverTally : any){ ... }

或创建以下类型的类

export class Driver {
   public string driver;
   public int numEscorts;
}

然后声明你的数组，

driverstally : Driver[] = [
                    { driver: 'driver1', numEscorts: 0},
                    { driver: 'driver2', numEscorts: 0},
                    { driver: 'driver3', numEscorts: 0} 
                ];

然后将其传递为

doStuff(driverTally :Driver[] ){ ... }
