自定义对象

<script>
//创建对象
//1.使用new关键字调用构造器创建对象
/*function Student(name,age){
alert("姓名:"+name+",年龄:"+age);
Student.sex = "男";

this.name = name;
this.age = age;
this.info = function(){
alert("姓名:"+name+",年龄:"+age+",性别:"+Student.sex);
}
}

var student = new Student("张三",20);
alert(Student.sex);
var student2 = new Student("张大三",26);
student.info();*/

//2.使用object创建对象
/*var obj = new Object();
obj.name = "得或";
obj.age = 25;
obj.info = function(){
alert(obj.name+":"+obj.age);
}

obj.info();*/

//3.使用json创建对象
/*var user = {
"name":"张三",
"age":20,
"info":function(){
alert(user.name+":" +user.age);
}};
alert(user.name);
user.info();

var peoples = {"p":[
{"name":"张三","age":20},
{"name":"李四","age":22}
]};

alert(peoples.p[1].age);*/
