Ich möchte Daten (Benutzername) von app.js zu main.js senden und auch Daten (Benutzername) von main.js zu App abrufen .js. Ich habe app.js, der Knoten ist, ruft index.html. Die index.html intern ruft die Funktion main.js auf. Hier ist mein Code.Senden und Abrufen von Daten von app.js (Knoten) zu javascript (main.js)
app.js
var http = require('http');
var fs = require('fs');
var express = require('express');
var path = require('path');
var app = express();
var username = 'username';
app.use(express.static('public'))
var request = require('request');
request('http://localhost:8000/test', function (error, response, body){
if (!error && response.statusCode == 200) {
console.log(body);
}
});
app.get('/', (req, res) => {
res.sendFile(path.join(__dirname + '/index.html'))
});
app.listen(3000,'127.0.0.1');
console.log('Listening on port 3000');
main.js
function clicked() {
var user = document.getElementById('username');
var pass = document.getElementById('password');
var checkuser = "test";
var checkpass = "123"
if (user.value == checkuser) {
if (pass.value == checkpass) {
window.location.href = "login.html";
}

window.alert("Incorrect username or Password");
}
