这篇文章主要介绍了Nodejs模块的调用操作,结合实例形式分析了nodejs模块的定义与调用相关操作技巧,需要的朋友可以参考下
本文实例讲述了Nodejs模块的调用操作。分享给大家供大家参考，具体如下：
User.js
//构造方法
function User(id, name, age) {
this.id = id;
this.name = name;
this.age = age;
this.enter = function () {
console.log(this.name + "进入国家图书馆");
}
}
/*
function User() {
this.id;
this.name;
this.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) {
User.apply(this, [id, name, age]);//类的继承
this.teach = function(res) {
res.write(this.name + "讲课");
}
}
module.exports = Teacher;
modalcall_1.js
//----------------------n3_modalcall.js模块的调用-------------
var http = require('http');
var User = require('./model/User');
http.createServer(function (request, response) {
response.writeHead(200, {
'Content-Type': 'text/html; charset=utf-8'
});
if (request.url !== "/favicon.ico") { //清除第2此访问
user = new User(1, "jack", 20);
//user.id = 1;
//user.name = "张三";
//user.age = 20;
user.enter();
response.end('');
}
}).listen(8000);
console.log('Server running at http://127.0.0.1:8000/');
modalcall_2.js
//----------------------n3_modalcall.js-------------
var http = require('http');
var Teacher = require('./model/Teacher');
http.createServer(function(request, response) {
response.writeHead(200, {
'Content-Type': 'text/html; charset=utf-8'
});
if(request.url !== "/favicon.ico") { //清除第2此访问
teacher = new Teacher(1, "JackLi", 20);
teacher.enter();
teacher.teach(response);
response.end('');
}
}).listen(8000);
console.log('Server running at http://127.0.0.1:8000/');
希望本文所述对大家nodejs程序设计有所帮助。
