在JavaScript构造函数下面,
function Person(){
this.name = arguments[0];
this.age = arguments[1];
}
let a: Person = new Person('Name1');
let b: Person = new Person('Name2', 20);
let d1: Date = new Date(0); // this works
let d2: Date = new Date(2012, 11); // this works
使用arguments
对象接收可变数量的参数。
tsc编译器说:
# tsc file.ts
file.ts(6,9): error TS2350: Only a void function can be called with the 'new' keyword.
file.ts(6,9): error TS2554: Expected 0 arguments, but got 1.
file.ts(7,9): error TS2350: Only a void function can be called with the 'new' keyword.
file.ts(7,9): error TS2554: Expected 0 arguments, but got 2
如何将可变数量的参数传递给JavaScript构造函数?
