Node简单的模块化小例子

 

 

模块化解决了JavaScript作用域互相污染问题，这里以写一个学校小例子，便于理解node的这个写法和一些简单的API（比如forEach这个.....）。

 文件：

依次student.js,teacher.js,kclass.js(class为保留字，不能命名),index.js,school.js

function add(student) {    console.log('Add student:' + student)}exports.add = add

function add(teacher) {    console.log('Add teacher:' + teacher)}exports.add = add

var student = require('./student')var teacher = require('./teacher')function add(teacherName, students) {    teacher.add(teacherName)    students.forEach(function(item, index) {        student.add(item)    })}exports.add = add

var kclass = require('./kclass')exports.add = function(kclasses) {    kclasses.forEach(function(item,index) {        var _klass = item        var teacherName = item.teacherName        var students = item.students        kclass.add(teacherName, students)    })}

var school = require('./index.js')var classesArr = [    {        'teacherName':'Bob',        'students':['SB1','SB2']    }];school.add(classesArr);
