HTML Ajax form not working with FormSubmit co API

I'm using Svelte and Astro. And I'm using formsubmit.co for the API to send the email. But it doesn't send the email.
Here is the js
<script>
import { onMount } from 'svelte';
import jq from 'jquery';
onMount(() => {
window.jq = jq;
jq("#form").submit(function (event) {
var formData = {
name: jq("#name").val(),
email: jq("#email").val(),
message: jq("#message").val(),
};
jq.ajax({
method: 'POST',
url: 'https://formsubmit.co/ajax/01e95b7b608117ff23368c8ea240889d',
dataType: 'json',
accepts: 'application/json',
data: formData,
success: (data) => console.log(data),
error: (err) => console.log(err)
});
});
});
</script>
Here is the form html
<form method="POST">
<div class="flex">
<input class="input-style" id="name" type="text" name="name" required placeholder="Name">
<input class="input-style" id="email" type="email" name="email" required placeholder="Email">
<input type="hidden" name="_subject" value="Downlu - Support Email">
</div>
<textarea class="input-style" id="message" name="message" type="message" cols="60" rows="4" placeholder="Message" required></textarea>
<button class="btn-submit" type="submit">Send</button>
</form>
It just reloads the page, and I've checked my email and nothing shows up.

FormData Returning Undefined in Ajax and Wordpress Form

I created a contact form for a Wordpress theme (custom) using jQuery/Ajax. When I tested the wp_send_json_sucess with "it works" it returned as suspected. However, when I added $formdata and the name of a field on the form the from returned undefined in the JS alert box. I'm pretty sure I've typed it correctly, as I was following this tutorial: https://www.youtube.com/watch?v=LYvx_L9ESn0. But I cannot seem to get it to work.
Code for functions.php here
add_action('wp_ajax_contact', 'contact_form');
add_action('wp_ajax_nopriv_contact', 'contact_form');
function contact_form()
{
$formdata = [];
wp_parse_str( $_POST['contact'], $formdata );
wp_send_json_success( $formdata ['myName'] );
}
Form Code Here :
<form id="contact">
Name: <input type="text" name="myName" class="contactform
fields" placeholder="name"required><br><br>
Email: <input type="text" name="myEmail" class="contactform
fields" placeholder="you#youremail.com" required><br><br>
<p>What is your inquiry regarding?</p><be>
<input type="radio" name="reason" value="general">
<label for="news">General Inquiry</label><be>
<input type="radio" name="reason" value="course">
<label for="news">Courses</label><br>
<p class="contact_txt">Your Message:</p>
<textarea name="msg" rows="5" cols="700" placeholder="begin
typing message here..." required>
</textarea>
<p class="contact_txt">Would you like to subscribe to our
newsletter?</p>
<br>
<input type="checkbox" name="news" value="Subscribe">
<label for="news">Yes, I would like to subscribe</label>
<br>
<input class="btns" name="btn-send" id="mySubmit" type="submit" value="submit">
<input class="btns" name="btn-reset" id="myReset" type="reset" value="reset">
</form>
Script Here :
<script>
jQuery('#contact').submit( function(event){
event.preventDefault();
var endpoint = '<?php echo admin_url('admin-ajax.php' ); ?>';
var form = jQuery('#contact').serialize();
var formdata = new FormData;
formdata.append('action', 'contact');
formdata.append('contact', 'form');
jQuery.ajax(endpoint, {
type: 'POST',
data: formdata,
processData: false,
contentType: false,
success: function(res){
alert(res.data);
},
error:function(err){
}
})
})
</script>

Jquery Not Sending the Form to HTTP

I'm having some problems with Jquery/Ajax.
This is my code for the form :
<form class="form-auth-small" method="POST" id="form" enctype="multipart/form-data">
<div class="form-group">
<label for="signin-email" class="control-label sr-only">Email</label>
<input type="email" class="form-control" name="email" value="samuel.gold#domain.com" placeholder="Email">
</div>
<div class="form-group">
<label for="signin-email" class="control-label sr-only">Name</label>
<input type="text" class="form-control" name="name" value="John">
</div>
<div class="form-group">
<label for="signin-email" class="control-label sr-only">Phone</label>
<input type="text" class="form-control" name="phone" placeholder="938434928">
</div>
<div class="form-group">
<label for="signin-email" class="control-label sr-only"></label>
<input type="password" class="form-control" name="password" placeholder="****">
</div>
<div class="form-group">
<input name="image" type="file" />
</div>
<button type="submit" id="submit" class="btn btn-primary btn-lg btn-block">Register</button>
</form>
And this is my code to AJAX/Jquery:
<script>
$(".submit").on("click", function(e) {
var form = $("#form");
// you can't pass Jquery form it has to be javascript form object var formData = new FormData(form[0]);
console.log(formData);
$.ajax({
type: "POST",
url: '/user/signup/',
data: formData,
contentType: false, //this is requireded please see answers above processData: false, //this is requireded please see answers above //cache: false, //not sure but works for me without this error: function (err) { console.log(err);
success: function(res) {
console.log(res);
},
});
});
</script>
When i do console.log to check that from form i don't receive any value, and when i check in network i dont see any HTTP callback.

Your code doesn't work because you were using the class selector token . (dot) instead of the id selector token # hashtag. Further details can be found on the documentation
Change this instruction
$(".submit").on("click", function(e) // …
to
$("#submit").on("click", function(e) // …

You dont have submit class. You have id="submit"
$("#submit").on("click", function(e) {
Use this and it should work.
Also change type="submit" to type="button" or in your js code you need to add
e.preventDefault();

Submit form with ajax via callback

I want to submit the form when a gcapcha was clicked. I tried submit with (my silly) jquery function that I know. But it's not work.
Here is my code (what's wrong with it).
Javascript
var verifyCallback = function(e) {
document.getElementById("form-contact").submit();
$.ajax({
type : 'POST',
url : 'inc/contact_sent.php',
data : $(this).serialize(),
success : function(data){
$("#contact").html(data);
}
});
return false;
};
var onloadCallback = function() {
grecaptcha.render("captcha", {
sitekey: "xxx",
callback: verifyCallback
})
};
HTML
<div id="contact" class="contact-form">
<form class="ajaxForm detailedsearch inline-style" method="post" id="form-contact">
<input type="text" class="form-control" name="cntc_name" placeholder="Your name" required>
<input type="email" class="form-control" name="cntc_email" placeholder="Your email" required>
<input type="text" class="form-control" name="cntc_tel" placeholder="Your phone">
<input type="text" class="form-control" name="cntc_subj" placeholder="Subject" value="<?=(isset($_POST['ptitle']))?"Queries for $_POST[ptitle]":""?>" required>
<textarea class="form-control" name="cntc_desc" rows="6" placeholder="Your Detail" required></textarea>
<div class="form-group">
<div id="captcha" class="center-captcha"></div>
<div id="gcaptcha" style="transform:scale(0.50);-webkit-transform:scale(0.50);transform-origin:0 0;-webkit-transform-origin:0 0;"></div>
<span class="text-danger">*Please complete the form to proceed.</span>
</div>
<!-- <button type="submit" class="btn btn-success btn-block"><i class="fa fa-envelope-o"></i> Submit Form</button> -->
</form>
</div>

You should do this....
//register a event for form submit
$( "form" ).submit(function( e ) {
e.preventDefault();
$.ajax({
type : 'POST',
url : 'inc/contact_sent.php',
data : $(this).serialize(), //serialize the form data
success : function(data){
$("#contact").html(data);
}
});
});
var verifyCallback = function(e) {
//submit form
$("#form-contact").submit();
return false;
};
var onloadCallback = function() {
grecaptcha.render("captcha", {
sitekey: "xxx",
callback: verifyCallback
})
};

run php script with ajax shows no result

I'm trying to run a php script using ajax after a form submission.
this is the form
<form id="form" class="form">
<input id="email" type="email" required name="email" placeholder="Email" onchange="myUpdateFunction()" value="">
<textarea id="message" type="text" value="" name="message" onchange="myUpdateFunction()" required placeholder="Comments" style="border:none;border-bottom:1px solid #424242; width:530px;"></textarea>
<input id="submit" type="submit" class="submit" name="send_request" value="Submit" >
</form>
this is my script
$('.submit').on('click', function() {
$.ajax({
url: "send.php",
method:'post',
data: {'email': $('#email').val(), 'message': $('#message').val()}
}).done(function() {
alert('Message Sent.');
});
});
and this is my send.php file
<?php
if(isset($_POST['send_request'])){
//send email
}
?>
but it doens't work, the page is reloaded, the email is not sent and no "alert message" is displayed
there is no problem in php because if I delete the javascript and I add action="send.php" method="POST" as attributes in the form it works, so I think that the problem is the javascript

You shouldn't use the onchange or the click event for this kind of stuff, but the submit event (preventing the default behaviour of submit button).
<form id="form" class="form">
<input id="email" type="email" name="email" placeholder="Email" required>
<textarea id="message" type="text" value="" name="message" placeholder="Comments" required></textarea>
<input id="submit" type="submit" class="submit" name="send_request" value="Submit">
</form>
$("#form").on('submit', function(e) {
e.preventDefault();
$.ajax({
url: "send.php",
method:'post',
data: $( this ).serialize()
}).done(function() {
alert('Message Sent.');
});
});
or (both ways are good)
$(document).ready(function () {
$('#submit').click(function () {
$.ajax({
url: "send.php",
method: 'post',
data: $(this).serialize()
}).done(function () {
alert('Message Sent.');
});
return false;
});
});
Also, about the backend, you should make this kind of check:
if (
isset($_POST["email"]) &&
!empty($_POST["email"]) &&
isset($_POST["message"]) &&
!empty($_POST["message"])) {
//send email
}
