NodeJs OOP的实现
NodeJs OOP的实现ModuleA.js
//static private
var static_private_name = "ModuleA_static_private_name";
//static public
ModuleA.static_public_name = "ModuleA_static_public_name";
function ModuleA() {
this.public_name = "ModuleA_public_name";
var private_name = "ModuleA_private_name";
this.public_hello = function() {
console.log("hello, my private_name is " + private_name + "\n" +
" public_name is " + this.public_name + "\n" +
" static_public_name is " + ModuleA.static_public_name + "\n" +
" static_private_name is" + static_private_name);
}
}
module.exports = ModuleA;
ModuleB.js
//static private
var static_private_name = "ModuleB_static_private_name";
//static public
ModuleB.static_public_name = "ModuleB_static_public_name";
//extends class
var superCls = require('./ModuleA');
require('util').inherits(ModuleB, superCls);
//constuctor
function ModuleB() {
//super();
superCls.call(this);
//public prop
this.public_name = "ModuleB_public_name";
var private_name = "ModuleB_private_name";
//override super method
var superPublic_hello = this.public_hello;
this.public_hello = function() {
console.log("override");
superPublic_hello.call(this);
}
}
module.exports = ModuleB;
var ModuleA = require("./ModuleA");
var ModuleB = require("./ModuleB");
var insA = new ModuleA();
//insA.public_hello();
var insB = new ModuleB();
insB.public_hello();
