面向对象 ( OO ) 的程序设计——创建对象

 1 function createPerson(name,age,job){
 2     var o = new Object();
 3     o.name = name;
 4     o.age = age;
 5     o.job = job;
 6     return o;

10 var person2 = createPerson("Lily",21,"Student");

1 function People(name, age, job){
2     this.name = name;
3     this.age = age;
4     this.job = job;
