json格式的javascript对象用法分析

objectName = { property1:value1, property2:value2, …, propertyN:valueN}

var user={ name:"user1", age:18};

var user={ //user本身是一个对象 name:"user1", job:{ //job也是一个对象  salary:3000,  title:programmer }}

var user={ //user本身为一个对象 name:"user1", age:18, getName:function(){ //getName为方法  return this.name; }}
