javascript - Call object property from within a callback -

I have an async.series () function calling from another javascript object:

Main.js

var object 1 = Required ('./ object1'); Var object 1 = requirement ('./ object2'); Async.series ([object1.myfunction1, object2.anotherFunction]);

object1.js

  module.exports = {function1: function (callback) {async.each (someArray, function (Item, CB) {function2 (item);}, function (mistake) {if (mistake) return callback (mistake); callback ();}); }, Function 2: function (item, callback) {// something}};  

This code does not work because function2 is undefined within the callback. I have tried to put

  var refToFunction2 = this.function2  

at the beginning of function 1. It works if we call function 1 directly, but function 1 is called async and for some reasons: this = undefined.

Is there a clean way to do this?

You can set up your object1.js file as follows :

  var Async = require ('async'); Function function1 (callback) {async.each (someArray, function (item, cb) {function2 (item);}, function (mistake) {if (return) return callback (err); callback ();}); } Function Function 2 (item, callback) {// something} module Export Function1 = function1; Module.exports.function2 = function2;  

You should now note that function1 and function2 are defined globally in the file. This means that they can be said independently within each other.
