1理解对象
1)创建对象
方法1
var person=new Object();
person.name="fuck";
person.age=16;
方法2
var person={
name:"fuck",
age:12
}
工厂模式
function People (name,age) {
var o=new Object();
o.name=name;
o.age=age;
o.sayName=function () {
return this.name;
}
return o;
}
var a=People("huangjiabing","23");
构造函数模式
function People (name,age) {
this.name=name;
this.age=age;
this.sayName=function () {
return this.name;
};
}
var a=new People("huangjiabing",23);
a instanceof Object;//true
a instanceof People;//true
在另一个作用域中调用构造函数
var o=new Object();
People.call(o,"huanggabing",23);
alert(o.sayName());
