以函数封装以特定接口创建对象的细节。
function createPerson(name, age, job) {
var o = new Object();
o.name = name;
o.age = age;
o.job = job;
o.sayName = function() {
alert(this.name);
};
return o;
}
var person1 = createPerson("Nicholas", 29," Software Engineer");
var person2 = createPerson("Greg", 27, "Doctor");
可创建多个相似对象,但没有解决对象识别问题(即怎样知道一个对象的类型)
function Person(name, age, job){
this.name = name;
this.age = age;
this.job = job;
this.sayName = function(){
alert(this.name);
};
}
var person1 = new Person("Nicholas", 29, "Software Engineer");
var person2 = new Person("Greg", 27, "Doctor");
工厂模式建立的对象只是object的实例,构造模式建立的对象既是object的实例,又是Person的实例,可以用于继承等。(所有对象都是object的实例)
