//對象字面量寫法var fn = {    name: ‘hello world‘,    fn1: function() {        console.log(this.name);    }};fn.fn1();//prototype原型寫法function Fn() {    this.name = ‘hello world‘;    this.fn1 = function() {        console.log(this.name);    };    Fn.prototype.fn2 = function() {        console.log(this.name);    };}Fn.prototype.fn3 = function() {   console.log(this.name);};Fn.prototype.init = function() {    fn.fn1();    fn.fn2();    fn.fn3();};var fn = new Fn();fn.init();
