Typescript参数不正确

Question

我正在尝试将此TypeScript数组传递给函数。我已经尝试了许多参数类型来进行编译，但它们似乎都不起作用。这是阵列：

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

Answer 1

如果你不确定类型，你可以使用任何一种，

doStuff(driverTally : any){ ... }

或创建以下类型的类

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

然后将您的数组声明为

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

然后传递给它，

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

Answer 2

我建议您确定界面：

interface IDriver {
    drive: string;
    numEscorts: number;
}

然后使用初始化声明数组：

public drivers: IDriver[] = [];

您可以将此数组作为函数参数传递：

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