node学习第三天（1）

今天学习了，node调用模块的方法

node调用模块

要调用模块的js

var http = require("http");

var Teacher = require("./Teacher");

http.createServer(function(request,response)
{

  response.writeHead(200,{'Content-Type':'text/html;charset=utf-8'});

  if(request.url!=='/favicon.ico'){

      teacher = new Teacher(1,"张三老师",30);

      teacher.enter();

      teacher.teach(response);

     response.end();

  } 

}).listen(8000);

console.log('Server running at http://127.0.0.1:8000/');

user.js

function User(id,name,age){
    this.id=id;
    this.name=name;
    this.age=age;
    this.enter=function(){
      console.log(this.name+"进入图书馆");
    }
    
}

module.exports = User;

Teacher.js

var User =require("./User");
function Teacher(id,name,age){
//Teacher通过apply继承User的属性
  User.apply(this,[id,name,age]);
  this.teach=function(res){
     res.write(this.name+"教学");
  }
}

module.exports = Teacher;

以上是源码。
