Javascript NodeJS中的Module.exports，输出功能

module1.js

module.exports = function (input, input2) {

  return "exported";

};

var module1 = require('/Users/Aakarsh/Desktop/Node/ToDo/playground/module1.js');

console.log(module1);

var myfunction= function() { ... };
exports.myfunction= myfunction;

var m = require('./a'); // require includes file by which function will be available
m.myfunction(); // Once function is available you can call 
            //just like normal JavaScript function

modulegetter.js

module.exports = function (input, input2) {

  return "exported";

};

var module1 = require('/Users/Aakarsh/Desktop/Node/ToDo/playground/module1.js');

console.log(module1);

var myfunction= function() { ... };
exports.myfunction= myfunction;

var m = require('./a'); // require includes file by which function will be available
m.myfunction(); // Once function is available you can call 
            //just like normal JavaScript function

输出内容：

[功能]

我希望它像在

module1.js

类中一样输出

“导出的”

。我能做什么

额外：

当我有这个时，在

modulegetter.js

中

var f = function (input, input2) {

    return "exp";

};

console.log(f("f", "f"));

---

它根据需要输出

exp

，但为什么它不能与module.exports一起工作？

您需要实际调用函数（带或不带参数）：

---

module.exports

公开可从其他文件访问的外部方法或变量。假设您有两个文件a.js和b.js

a.js

module.exports = function (input, input2) {

  return "exported";

};

var module1 = require('/Users/Aakarsh/Desktop/Node/ToDo/playground/module1.js');

console.log(module1);

var myfunction= function() { ... };
exports.myfunction= myfunction;

var m = require('./a'); // require includes file by which function will be available
m.myfunction(); // Once function is available you can call 
            //just like normal JavaScript function

b.js

module.exports = function (input, input2) {

  return "exported";

};

var module1 = require('/Users/Aakarsh/Desktop/Node/ToDo/playground/module1.js');

console.log(module1);

var myfunction= function() { ... };
exports.myfunction= myfunction;

var m = require('./a'); // require includes file by which function will be available
m.myfunction(); // Once function is available you can call 
            //just like normal JavaScript function

模块1和模块1（）之间的区别是什么？

module1（）

执行/调用函数，

module1

只是对函数的引用，并返回函数本身，而不是其结果/返回。
