1、对象
1、基于Obeject
var obj = new Object();
obj.name = 'eric';
obj.age=25;
obj.sex='男'；
obj.getName = funtion(){
return this.name;
}
2、基于字面量
var obj = {
name:'eric',
age: 25,
sex:'男',
getName: function(){
return this.name;
}
}
2、创建对象方式
1工厂模式
function fun(name,age,sex){
var obj = new Object();
obj.name = name;
obj.age = age;
obj.sex = sex;
obj.setName = function(){
return this.name;
}
return obj
}
fun('eric',25,'男');
2构造函数
function fun(name,age,sex){
this.name = name;
this.age = age ;
this.sex = sex ;
this.setName = function(){
return this.name;
}
}
var obj = new fun('eric',25,'男');
3原型模式
function fun(){
}
fun.prototype.name = 'eric';
fun.prototype.age = 25;
fun.prototype.sex = '男';
fun.prototype.getName = function(){
return this.name;
}
var obj = new fun();
var obj1 = new fun();
obj === obj1 //false(不是同一个obj);
obj.getName() === obj1.getName() // true (不同object公用一个原型对象方法)
