创建直接的实例-使用对象构造器

前言：依赖库，只是应用；掌握核心，才能创造。

复习JavaScript原生，一点一点记录。

function fun(name,firstname,age,color){
	this.name=name;
	this.firstname=firstname;
	this.age=age;
	this.color=color;
}
var people1=new fun("sudonghao","su",20,"red");
console.log(people1.name+people1.firstname+people1.age+people1.color)//sudonghaosu20red
var people2=new fun("hanmeimei","han",18,"green");
console.log(people2.name+people2.firstname+people2.age+people2.color)//hanmeimeihan18green
