Nodejs calling function

First, call the normal function

Declaring functions:

function Fun1 (res) {Console.log ("fun1"); Res.write ("I ' m fun1");}

Called within the same file:

FUN1 (response);

Second, call the functions in other files

Declare the function and export:

function Fun2 (res) {Console.log (' I am fun2 '); Res.write (' I ' m fun2 ');} Module.exports = fun2;

Introducing Modules:

var otherfun = require ('./models/otherfuns ');

'./models/otherfuns.js ' indicates the file path where the fun2 is located

Call Function:

OTHERFUN.FUN2 (response);

Third, export multiple functions

Module.exports = {Fun2:function (res) {Console.log (' I am fun2 '); Res.write (' Hello, I am fun2 ');},fun3:function (res) { Console.log (' I am fun3 '), Res.write (' Hello, I am fun3 ');}}

Iv. calling the corresponding function with a string

otherfun[' fun2 ' (response); otherfun[' Fun3 '] (response);
