Submitting a form to the server?

Question

HTML

How to send and receive a simple form correctly:

<form name="test" method="post" action="/comment">
       <p><b>Ваше имя:</b><br>
       <input type="text" size="40">
       </p>
      <input type="submit" value="Отправить">
</form>

How to accept such a form on the server?

app.post('/comment',jsonParser,function (req,res,next) {
    console.log(req.body.email)
});

And why does it load another page after submitting?

Answer 1

You need to remove the jsonParser middleware and return a response

app.post('/comment',function (req,res,next) {
    console.log(req.body.email);
     res.send('Hello World!');
});

And read expressjs.com/ru/guide/using-middleware.html

Answer 2

so that after sending it does not reload the page, you need to put an onSubmit handler and write event.preventDefault()
