面向对象

1.工厂模式:

function Person(name, sex) {
    var obj = new Object();
    obj.name = name;
    obj.sex = sex;
    obj.showName = function() {
    alert('我的名字叫：' + obj.name);
}
obj.showSex = function() {
	alert('我是：' + obj.sex + '的');
}
return obj;
}
var p1 = Person('char', '男');
p1.showName();
p1.showSex();

2.new方式:

function Person(name, sex) {
    this.name = name;
    this.sex = sex;
    this.showName = function() {
        alert('我的名字叫：' + this.name);
    }
    this.showSex = function() {
        alert('我是：' + this.sex + '的');
    }
}
var p1 = new Person('char', '男');
p1.showName();
p1.showSex();
