利用函数的思想
function create(name, sex, age){
var obj = new Object();
obj.name = name;
obj.sex = sex;
obj.age = age;
obj.say = function(){
document.write('hello');
}
return obj;
}
var p1 = create('shuang', 'woman', 20);
构造函数法(常用)
function Person(name, age, sex){
this.name = name;
this.age = age;
this.sex = sex;
this.say = function(){
document.write('hello');
}
}
var p1 = new Person('ao', 21, 'man');
简单原型
function Person() {
}
Person.prototype = {
name : 'zs',
age : 20,
job : 'doctor',
say : function () {
document.write( 'wo shi yuanxing ' );
}
};
// 三个参数。 参数1: 重设构造器的对象 参数2:设置属性 参数3 :options配置项
Object.defineProperty( Person.prototype, 'construction', {
enumerable : false,
value : Person
});
var p = new Person();
document.write( p.name );
p.say();
