JS - recaptcha v3 - how to verify captcha and submit form data to another file

I'm just starting with JS and like to implement a form that verifies for robots/humans by using captcha v3 on the client side and if verification succeeds the data should be submitted to another file.
This is what I got so far. I know it's wrong, but unsure what the correct logic is. Hope someone can shed a light. Thx!

Form validation with Ajax call triggers when not validation

I have a simple form with Ajax call, but ajax call gets executed even if form is not validated.
In below code line console.log("This line should execute only if Form is validated"); gets executed when form is not validate.
Bootstrap 5 validation Codepen code
(function () {
"use strict";
const forms = document.querySelectorAll(".requires-validation");
Array.from(forms).forEach(function (form) {
form.addEventListener(
"submit",
function (event) {
if (!form.checkValidity()) {
event.preventDefault();
event.stopPropagation();
}
else
{
console.log("This line should execute only if Form is validated");
// Call Ajax Function
// AjaxCallSaveData();
}
form.classList.add("was-validated");
},
false
);
});
})();
//$(document).ready(function () {
function AjaxCallSaveData()
{
$("form").submit(function (event) {
var formData = {
name: $("#name").val(),
email: $("#email").val(),
message: $("#message").val(),
superheroAlias: $("#superheroAlias").val()
};
$.ajax({
type: "POST",
url: "SubmitFORM.php",
data: formData,
dataType: "json",
encode: true
}).done(function (data) {
console.log(data);
});
event.preventDefault();
});
}
//});
Not sure if i am doing it right?
HTML
<div class="form-body">
<div class="row">
<div class="form-holder">
<div class="form-content">
<div class="form-items">
<h3>Register you interest</h3>
<p>Fill in the data below, we will get back to you!</p>
<form class="requires-validation" action="SubmitFORM.php" method="POST" novalidate>
<div class="col-md-12 mb-3">
<input class="form-control" type="text" name="name" id="name" placeholder="Full Name" required>
<div class="valid-feedback">Username field is valid!</div>
<div class="invalid-feedback">Username field cannot be blank!</div>
</div>
<div class="col-md-12 mb-3">
<input class="form-control" type="email" name="email" id="email" placeholder="E-mail Address" required>
<div class="valid-feedback">Email field is valid!</div>
<div class="invalid-feedback">Email field cannot be blank!</div>
</div>
<div class="col-md-12 mb-3">
<textarea name="message" id="message" placeholder="Your Message"></textarea>
</div>
<div class="form-button mt-3">
<button id="submit" type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
</div>
</div>
</div>
</div>
</div>

event.preventDefault() will only stop the form from submitting. It cannot stop next lines of the JavaScript function from executing.
You should use return in place of event.preventDefault().

fetch doesn't send autofilled input

When my login credentials are prefilled by my browser (chrome) my fetch function doesn't send the values
html
<div class='login-frame'>
<h3>Bienvenue</h3>
<div class='form'>
<div class='input-handler'>
<label for='login'>Login</label>
<input type='text' id='login' name='login' autocomplete='on'>
</div>
<br>
<div class='input-handler'>
<label for='pass'>Mot-de-passe</label>
<input type='password' id='pass' name='pass' autocomplete='on'>
</div>
<br>
<button id='loginbutton'>CONNEXION</button>
</div>
</div>
JS
window.onload = function() {
var pass = document.getElementById('pass'),
login = document.getElementById('login'),
loginButton = document.getElementById('loginbutton');
loginbutton.onclick = (e)=> {
var creds = {
login: login.value,
pass: pass.value
}
fetch('functions/log.php', {
method: "POST",
header: {"Content-type": "application/json; charset=UTF-8"},
body: JSON.stringify(creds)
});
}
PHP
$pos = json_decode(file_get_contents('php://input', true));
echo var_dump($pos);
If I type anything, it returns
object(stdClass)#3 (2) {
["login"]=>
string(3) "qfz"
["pass"]=>
string(5) "zfqzf"
}
If I use the browser prefill, it returns
NULL

It was a mistake,
as #CBroe said, it was a security problem. Changing my html to a proper form make it works as it should
<form class='login-frame' method='post' action='#'>
<div class='login-logo'><img src='bs/img/logo_b.svg'></div>
<h3>Bienvenue</h3>
<div class='form'>
<div class='input-handler'>
<label for='login'>Login</label>
<input type='text' id='login' name='login' autocomplete='on'>
</div>
<br>
<div class='input-handler'>
<label for='pass'>Mot-de-passe</label>
<input type='password' id='pass' name='pass' autocomplete='on'>
</div>
<br>
<button type='submit' id='loginbutton'>CONNEXION</button>
</div>
</form>

How can I get my search bar work with Google?

I have this search bar and I can't connect it to Google as a search functionality, I tried with this guy's code but I couldn't:
<form id="frmSearch" action="index.html" class="searchform order-sm-start order-lg-last">
<div class="form-group d-flex">
<input type="text" class="form-control pl-3" placeholder="Buscar">
<button type="submit" placeholder="txtsearch" class="form-control search"><span class="fa fa-search"></span></button>
</div>
</form>
Thanks in advance!

You could use an AJAX call to a php page where you are going to implement cURL to get data from google searching url!
Of course you will need to code your own cURL in PHP: PHP + curl, HTTP POST sample code?
here you can find how to implement it!
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
document.addEventListener('DOMContentLoaded', () => {
const form = document.querySelector("form#frmSearch");
form.onsubmit = function() {
let keyword = encodeURIComponent(this.querySelector("input#keyword").value);
$.ajax({
url: `./php_curl_file.php?q=${encodeURIComponent(keyword)}`,
type: 'GET',
error: (err) => {
throw new Error(err);
},
success: (searchData) => {
console.log( searchData );
}
});
return false;
}
} );
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="frmSearch" class="searchform order-sm-start order-lg-last">
<div class="form-group d-flex">
<input type="text" id="keyword" class="form-control pl-3" placeholder="Buscar">
<button type="submit" placeholder="txtsearch" class="form-control search">
<span class="fa fa-search"></span> Search
</button>
</div>
</form>

Form doesn't submit on callback

I am trying to send an e-mail after an ajax call has been successfully completed. I do not have access to the file that I am making the AJAX call to.
I am preventing the first submit, making the ajax call and submitting the form again upon competition. When doing this, I can't seem to figure out why I have to press the submit button twice for the email to be sent.
Here is my code:
"use strict";
var submitted = '';
/* Send info to the portal */
jQuery(function($) {
$('#quote').submit(function(e){
var firstName = $('#firstName').val(),
lastName = $('#lastName').val(),
email = $('#email').val(),
phone = $('#primaryPhone').val(),
weight = $('#weight').val(),
origin = $('#originPostalCode').val(),
destination = $('#destinationPostalCode').val(),
notes = $('#whatsTransported').val()
if( submitted != 1 )
{
e.preventDefault();
$.ajax({
type: "POST",
url: "https://somewhere.on/the/internet.php",
crossDomain: true,
dataType: "json",
data: {"key": "my secret key","first": firstName, "last": lastName, "email": email, "phone": phone, "weight": weight, "origin_postal": origin, "dest_country": destination, "note": notes }
})
.done(function(data){
if(data[1][0][0] == 2)
{
$('.alert').append( data[1][0][1].message ).addClass('alert-error').show();
} else if(data[1][0][0] == 0) {
console.log("Made it.");
$('#quote #submit').submit();
} else {
$('.alert').append( "Appologies, it seems like something went wrong. Please, <strong>call (877) 419-5523</strong> for immediate assistance or a free quote.");
}
})
.fail(function(data) { console.log(data); });
}
submitted = '1';
});
});
Here is the form HTML
<form action="<?php echo bloginfo($show='template_url').'/includes/form-email.php'; ?>" class="span6 offset1" id="quote" method="post">
<div class="row formRow">
<div class="firstName span3">
<label for="firstName"><?php _e('First Name:','StreamlinedService'); ?></label>
<input type="text" name="firstName" id="firstName">
</div>
<div class="lastName span3">
<label for="lastName"><?php _e('Last Name:','StreamlinedService'); ?></label>
<input type="text" name="lastName" id="lastName">
</div>
</div>
<div class="row formRow">
<div class="email span3">
<label for="email"><?php _e('Email Address:','StreamlinedService'); ?></label>
<input type="text" name="email" id="email">
</div>
<div class="primaryPhone span3">
<label for="primaryPhone"><?php _e('Phone Number:','StreamlinedService'); ?></label>
<input type="text" name="primaryPhone" id="primaryPhone">
</div>
</div>
<div class="row formRow">
<div class="weight span2">
<label for="weight"><?php _e('Weight (lbs):','StreamlinedService'); ?></label>
<input type="text" name="weight" id="weight">
</div>
</div>
<div class="row formRow">
<div class="originPostalCode span3">
<label for="originPostalCode"><?php _e('Origin:','StreamlinedService'); ?></label>
<input type="text" name="originPostalCode" id="originPostalCode">
</div>
<div class="destinationPostalCode span3">
<label for="destinationPostalCode"><?php _e('Destination:','StreamlinedService'); ?></label>
<input type="text" name="destinationPostalCode" id="destinationPostalCode">
</div>
</div>
<div class="row">
<div class="whatsTransported span6">
<label for="whatsTransported"><?php _e('What can we help you transport?','StreamlinedService'); ?></label>
<textarea name="whatsTransported" id="whatsTransported" rows="5"></textarea>
</div>
<input type="hidden" name="formType" value="quote" />
<input type="hidden" name="siteReferer" value="<?php echo $blog_id ?>">
<input type="submit" id="submit" name="submit" value="<?php _e('Get Freight Quote','StreamlinedService') ?>" class="btn btn-primary btn-large span3 offset3" style="float:right;">
</div>
</form>
My question is two-fold: Is there a more efficient way to do this? If not, why isn't this working?

Just use the .submit directly on the form node (note the [0])
$('#quote #submit').submit();
becomes
$('#quote')[0].submit();
this bypasses the jQuery bound event and forces a postback.

You use the wrong approach to Jquery
You miss the key : Write Less Do More, the heart of JQuery.
Anyway try this:
"use strict";
/* Send info to the portal */
jQuery(function($) {
$('#quote').submit(function(e){
var tis = $(this);
$.ajax({
type: "POST",
url: "https://somewhere.on/the/internet.php",
cache: true,
dataType: "json",
data: tis.serialize(),
success: function(data){
if(data[1][0][0] == 2){
$('.alert').append( data[1][0][1].message ).addClass('alert-error').show();
} else if(data[1][0][0] == 0) {
console.log("Made it.");
$('#quote #submit').submit();
} else {
$('.alert').append( "Appologies, it seems like something went wrong. Please, <strong>call (877) 419-5523</strong> for immediate assistance or a free quote.");
}
},
error: function(data){console.log(data);}
});
e.stroPropagation();
e.preventDefault();
});
});
