Hello, what I want to do is redirect to a servlet from a jsp using ajax, since I have to send data that are not in the form, but should not be seen in the url colo are mascot, age and the token since the latter expires every so often, so it must be sent to know if it is still valid and if so in the servlet make use of the data written by the user and sent anonymously
This is the code in js
$("#forma").submit(function () {
var name = $('#nombre').val();
var ape = $('#apellido').val();
$.ajax({
url: '/TomarValor',
type: 'POST',
data: {nombre: name, apellido: ape, mascota: yuki, edad:22, token:qwerty123}
});
});
este es el código html<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<!doctype html>
