javascript Login

[filippo]

Hi to everyone, I have a simple question .
I am writing an application for xerox machine that interface with efi Rip.
Xerox app use Javascript, so i need to write my app in javascript. the only problem is that I've never use javascript so I'd like to know how can I re-write for example the "login" funcion (from nodejs to javascript) so I can start develop my app.
Is there anyone that can tell me how could I do?

I explain better my question.
the only things I 'd like to know is how rewrite login function from Nodejs to Javascript, because in javascript I have not 'require(https)'..
I'll post my function:
----------
function login(){

var loginJson = {
username: "MyUsername",
password: "MyPass",
accessrights: MyapiKey,
};

var payload = JSON.stringify(loginJson);

var len = payload.length;


var xhr = new XMLHttpRequest();
var url = 'https://192.168.0.136/live/api/v3/login';
xhr.open("POST", url, true);
xhr.setRequestHeader('Access-Control-Allow-Headers', '*');
xhr.setRequestHeader('Access-Control-Allow-Origin', '*');
xhr.setRequestHeader("Content-type", "application/json");
xhr.setRequestHeader("Content-Length", "len");
xhr.onreadystatechange = function () {
if (xhr.readyState === 4 && xhr.status === 200) {
var json = JSON.parse(xhr.responseText);
console.log(json);
}
};

xhr.send(payload);
}
----------------------------------------------------------------------
when i run this function I got an error
