nodejs自学.js
function hello(){
console.log("hello world");
}
function s(){
console.log("this is a ew");
}
function add(a, b){
return a+b;
}
exports.hello = hello;//留出接口
exports.s = s;
exports.add = add;
test.js
//加载模块
var app = require("./nodejs自学");//./表示当前目录,也可以填"./nodejs自学.js"
app.hello();
app.s();
console.log(app.add(1,3));
在终端中 node test.js
结果:
hello world
this is a ew
