对象的四种创建方法

 1、对象自变量方法   较为简便

var hero = {
            name:'黄忠',
            weapon: '弓箭',
            equiment: ['弓箭','靴子','盔甲'],
            attack: function () {
                console.log(this.name + '：射箭');
            },
            run: function () {
                console.log(this.name + '：加速跑');
            }
        }
//引用
console.log(hero.name);
console.log(hero.equiment);
hero.attack();
hero.run();

2、new Object()    Object一个构造函数  new 用来调用构造函数  对比上一个方法此方法属性和方法个数可以随时改动

var hero = new Object();        /!*创建了一个空的对象*!/
        hero.name = '黄忠';           /!*设置属性*!/
        hero.weapon = '弓箭';
        hero.equipment = ['头盔','靴子','盔甲'];      /!*设置方法*!/
        hero.attack = function () {
            console.log(this.name + '：射箭');
        }
        hero.run = function () {
            console.log(this.name + '：加速跑');
        }
//引用
console.log(hero.name);
console.log(hero.equipment);
hero.attack();
hero.run();

3、工厂方法  此方法使用于多个对象具有相同的属性和方法

function createHero(name, weapon, equipment, blood) {
            var hero = new Object();
            hero.name = name;
            hero.weapon = weapon;
            hero.equipment = equipment;
            hero.attack = function () {
                console.log(this.name + '攻击');
            }
            hero.run = function () {
                console.log(this.name + ':加速跑');
            }
            return hero;
        }
//引用
var hero1 = createHero('黄忠','弓箭',['头盔','靴子'],100);
var hero2 = createHero('刘备','剑',['头盔','靴子'],100);

4、自定义构造函数 和上个方法一样都是用于多个对象具有相同的属性和方法 但比上一个方法更简洁

function Hero(name,weapon,equipment,blood) {
        //    this 动态的给对象增加成员
        //    this 指向了当前对象
            this.name = neme;
            this.weapon = weapon;
            this.equipment = equipment;
            this.blood = blood;
            this.attack = function () {
                console.log(this.name + '攻击');
            }
            this.run = function () {
                console.log(this.name + ':加速跑');
            }
        }
        var hero1 = new Hero('黄忠','弓箭',['头盔','靴子'],100);
        var hero2 = new Hero('刘备','剑',['头盔','靴子'],100);
