1 var person = new Object();
2 person.name = ‘Erza‘;
3 person.age = 26;
4 person.job = ‘engineer‘;
5 person.sayName = function(){
6   alert(thhis.name)  
7 }

最简单创建自定义对象的方式就是创建一个Object实例，然后再为它添加属性和方法

1 var person = {
2     name : ‘Erza‘,
3     age : 26,
4     job : ‘engineer‘,
5     sayName : function(){
6         alert(this.name)
7     }      
8 }
