类

1、构建一个类

class Person{
    //name  是实例的name
    name:string
    age:number
    constructor(name,age){
        this.name=name;
        this.age=age;
    }
    getName():void{
        console.log(this.name);
    }
}
var p:Person=new Person("ming",18);
p.getName();

2、static

class Person{
    //skill属于Person类
    static skill:string="js"
    //name  是实例的name
    name:string
    age:number
    getName():void{
        console.log(Person.skill);//js
        console.log(this.name);
    }
}
var p:Person=new Person();
p.getName();
