Ajax output from a form to a file, how?

I don't know php at all and I don't know how to work with Ajax.
I'm trying to send the text entered by the guest from the form to a separate file, but I can't figure out how to correctly format this data in JS and how to correctly accept it in php.
Tried to first set it like this
var getMail = $('.form-back__window').children('form').children().first().val();
var getName = $('.form-back__window').children('form').children().first().next().next().val();
var getNumber = $('.form-back__window').children('form').children().last().prev().prev().val();
var send = "mail: " + getMail + ", Name: " + getName + ", Number: " + getNumber;

and send the send variable, but I didn’t figure out whether it’s possible to extract in php what what she keeps.
Then did this

var send = {
"mail": getMail,
"name": getName,
"number": getNumber

type: 'POST',
url: "../php/main.php",
success: function(){
$ ('.form-back__window').children('form').hide();
$('.form-back__window').val('Reply received, thanks!');

tried to google how to process it, it turned out

if($_POST['send2']) {
$send2 = json_decode($_POST['send2']);
$row2 = get_text($send2->name);
$row3 = get_text($send2->number);

$file = fopen("GuestData.txt", "a");
fwrite($file, json_encode($row1));
fwrite($file, json_encode($row2));
fwrite($file, json_encode($row3));

The idea is simple, but how it is sawn, xs.

Here is the hmtl form

For the client side:

$.post('/youURL', $('form').serialize(), function (response) {
    //Code 200.

It is better to specify a more precise selector for the desired form, for example: On the server, check whether the parameters have arrived (key = name attribute in each input tag). If yes, write down:
if(!empty($_POST['name']) && !empty($_POST['other'])) {
  $filename = 'GuestData.txt';
  $somecontent = $_POST['name']."\r\n";
  if (is_writable($filename)) {
    if (!$handle = fopen($filename, 'a')) {
    if (fwrite($handle, $somecontent) === false) {
    //return some

This is just an example. On the server side, specify the parameters you need for full performance.

Something html form didn't submit

The most convenient way is to use FormData, which creates sets of key-value pairs, then sends it using the POST method.
