TypeScript專題-Static和使用技巧

class People {
	static _name: string; 
	print() {
		//alert(this.name);// 編譯不通過，doex not exist on type People；聲明為static的變量通過類名調用
        return(People._name)
	} 
    constructor(name){
        People._name = name;
    }
}
// let h = new People(); 
// // h.name = "aaa";
// People._name = "aaaa";
// h.print();
//創建類型，為當前類的類型(引用數據類型)
let p:People;
p = new People("aa");
alert(p.print())
