in my project we tried to build protractor framework. so in js file we create some functions using this.functionname syntax and we want to re use that function when it required in the function which is also present in the same file. for clear view i gave the code below...

this is my reusable functions JS file

var fb=require("H:/workspace/Protractor_PT/src/pages/FbPage.js");
var action=function()

 beforeAll(function()
 browser.ignoreSynchronization=true;
 browser.get("https://facebook.com");
 login();
 );

 this.clickElement=function(element)
 element.click();
 

 this.enterText=function(element,text)
 element.sendKeys(text);
 

 var login=function()
 action.enterText(fb.emailField(),"dfdsfds");
 action.enterText(fb.passfield(),"dfdsfds");
 

module.login=new action();

on top, you can find the functions this.clickElement and this.enterText.. i want to use those functions in the other function named login.. but when i called those functions with "action.enterText" - action is the main global variable of the file... i'm getting below error

Error Log

In your case when the inner functions are created the variable action is unknown to them.
You can do a local variable which points to the parent function and use it instead of the action.

You can do something like this:

var fb = require('H:/workspace/Protractor_PT/src/pages/FbPage.js')
var action = function () 
 var localAction = this; // <<<----------- HERE
 beforeAll(function () 
 browser.ignoreSynchronization = true
 browser.get('https://facebook.com')
 login()
 )
 this.clickElement = function (element) 
 element.click()
 
 this.enterText = function (element, text) 
 element.sendKeys(text)
 
 var login = function () 
 localAction.enterText(fb.emailField(), 'dfdsfds') // Use local var here.
 localAction.enterText(fb.passfield(), 'dfdsfds')
 

module.login = new action()
