【07】JavaScript面向对象

1. 使用字面量创建对象

     var stu = {
		"name":"zhangsan",
		"age":19,
		"phone":"13598745685",
		"sayHi":function(){
			 alert('hello')
		 },
		 "study":function(){
			 return 95;
		 }
	 };
	 
	 alert("姓名：" + stu.name)
	 alert("年龄：" + stu.age)
	 alert("电话：" + stu.phone)
	 stu.sayHi()
	 alert(stu.study())

2. 使用类创建对象 – 无参

     function Person(){
		 this.name = "张三";
		 this.age = 25;
		 this.say = function(){
			 alert('name='+this.name+" ，age="+this.age)
		 },
		 this.exam = function(course){
			 alert('参加'+ course + '考试')
		 }
	 }
	 
	 var zhangsan = new Person();
	 alert(zhangsan.name)
	 alert(zhangsan.age)
	 zhangsan.say()
	 zhangsan.exam('JavaScript')

3. 使用类创建对象 – 有参

     function Person1(name,age){
		 this.name = name;
		 this.age = age;
		 this.say = function(){
			 alert('name='+this.name+" ，age="+this.age)
		 }
	 }
	 var lisi = new Person1('lisi',20)
	 lisi.say()
