how to send the selected drop down element from client to server using node js - express - node.js

Question

I am new to node js and i am stuck to send the selected drop down element (like java,angular see below ex ) from client to server using node js - express. When i try to print it in console. system displays an error message "undefined " for drop down elements. Please help me on this. Thanks in advance.
EJS code
<form method="POST" action="/viewreg.html">
<select name="Courses" form="Courses">
<option value="Java">Java</option>
<option value="Angular">Angular</option>
<option value="Automation">Automation</option>
</select>
<input type='submit'name ='register' onclick="form.action='viewreg.html'"
</form>`
Server side -
const http = require('http');
const express = require('express');
const bodyparser=require('body-parser');
const path=require('path');
const hostname = 'x.x.x.x'
const port = 80;
const app = express();
app.use(bodyparser.json());
app.use(bodyparser.urlencoded({extended:true}));
app.use(express.static(path.join(__dirname,'public')));
app.set('view engine','ejs');
app.set('views',path.join(__dirname,'views'));
app.use(bodyparser.json());
app.use(bodyparser.urlencoded({extended:true}));
const dir=path.join(__dirname,'public');
app.set('view engine','ejs');
app.set('views',path.join(__dirname,'views'));
app.post('/viewreg.html',function(req,res) {
const newuser= {
emp_name:req.body.emp_name,
emp_id:req.body.emp_id,
phone_no:req.body.phone_no,
Team:req.body.selectpicker,
courses:req.body.Courses,
}
console.log(newuser);
});

You need to revisit the below issues which exist in your code.
Change your action url from action="/viewreg.html"> to
action="/viewreg">
There is no need to have onclick="form.action='viewreg.html'" in
your submit button.
You don't have an ID attribute attached to your <select> tag
where as you have a form attribute incorrectly over there.
You need to re-write your ejs tempalte as,
<form method="POST" action="/viewreg">
<select name="Courses" id="Courses">
<option value="Java">Java</option>
<option value="Angular">Angular</option>
<option value="Automation">Automation</option>
</select>
<input type='submit'name ='register'>
</form>
Also try changing your console.log(newuser); as,
console.log(req.body.Courses);
which will resolve your issue.
Hope this helps!
