测试JS基本类型以及对象的引用

自己敲的。
1 <script src="https://ajax.googleapis.com/ajax/libs/prototype/1.7.1.0/prototype.js" type="text/javascript"></script>

<script type="text/javascript" language="javascript" charset="utf-8">
var a = new Number(5);
var b = a;
a = 6;
console.info(b);//输出一个number对象
console.info(b.toString());//值为5
var c = 5;
console.info(c);//直接打印5,那么这个是基本数据类型。
console.info(a == b);//false
console.info(a === b);//false
a = 5;
console.info(a == b);//true,值相等,但确切说，不是同一个对象
console.info(a === b);//false
a = 5;
b = a;
console.info(a == b);//true  现在是同一对象了
console.info(a === b);//true

function Man(){
this.love = "爱";
}
Man.prototype = {
__proto__:new Man(),//不加这句的话，就不会有名字。Man对象的原型名就叫Man，但意思又是继承了Man,把Man中的属性弄成了，反正不要这样。
"name":"小王",
"age":23,
sex:"男"
}
var m = new Man();//打印的对象
//m.prototype.name = "小李";//m，实例无法更改原型属性
Man.prototype.name = "小李";
var m2 = m;
m2.love="不爱";
console.info(m);
console.info(m.love);//不爱，指向同一个对象。
console.info(m == m2);//true
console.info(m === m2);//true

function People(name,age,sex){
this.name = name;
this.age = age;
this.sex = sex;
}

var p = new People("小王",23,"男");

console.info(p1);//"小王1",23,"男"
console.info(p == p1);//false
console.info(p === 1);//false
console.info(p == p2);//true
console.info(p === p2);//true

var Animal = Class.create();

擦，地址忘了。叉了就忘了。
