function Person(first,last,age,gender,interests){
    this.name = {
        first,
        last
    };
    this.age = age;
    this.gender = gender;
    this.interests = interests;
    this.bio = function(){
        alert(this.name.first + ' ' + this.name.last + 'is' +this.age)
    };
    this.greeting = function(){
        alert('Hi! I\'m' + this.name.first + '.');
    };
}

创建对象实例：

var person1 = new Person('xiang','xing',22,'male',['music', 'skiing']);

访问属性方法：

person1['age']
person1.interests[1]
person1.bio()
