I have seen a number of methods dating back to about 2011 in order to take a form and have its data posted via ajax.jquery. I have tried a couple and am just getting the page to reload despite using preventdefault functions.
I am trying to take data from my form, have the jQuery listen for the form submit by targeting the actual form id and then call a PHP function in order to have that data posted to the db. Ultimately nothing happens other than a page reload. Since this is a WP page, I know that some of the functions and handling differ from regular webpages. Things like the ajax url, can be passed back to the functions etc. That is why I Am posting this here.
the form:
function add_entry(){
?>
<form action="" method="post" id="ajax-add-to-form" autocomplete="off">
<input type="text" id="FName" name="FName" placeholder="First Name" value="" required>
<input type="text" id="LName" name="LName" placeholder="Last Name" value="" required>
<select id="size" required>
<option value="">Size</option>
<?php for($i=1; $i<=15; $i++){?>
<option value="<?php echo $i; ?>"><?php echo $i; ?></option>
<?php } ?>
</select>
<input type="text" id="MobileNumber" name="MobileNumber" placeholder="Phone Number" value="" required>
<input type="email" id="Customer_Email" name="Customer_Email" placeholder="Email Address" value="" required>
<input type="submit" name="ajax-add-to-form" value="Add to">
<?php
}
add_shortcode('add_entry', 'add_entry');
</form>
the jquery
jQuery('document').ready( function(){
jQuery('#ajax-add-to-form').on('submit', function(e){
e.preventDefault();
jQuery('#jx-loading').show();
jQuery.ajax({
type: 'post',
url: my_ajax.ajax_url,
data: {
action: 'ajax-php-function'},
success: function(data)
{jQuery('#jx-loading').hide();}
})
});
return false;
});
the php
function ajax-php-function() {
global $wpdb;
$table = "mytablename";
$FName= $_POST['FName'];
$LName= $_POST['LName'];
$MobileNumber= $_POST['MobileNumber'];
$Email = $_POST['Email '];
$data = array(
'FName' => $FName,
'LName' => $LName,
'MobileNumber' => $MobileNumber,
'Email' => $Email);
$success = $wpdb->insert( $table, $data );
if($success)
{echo json_encode($last_data);}
else{ echo 'error'; } die;
}

Reset to default 0Ultimately the form and its old handler were being trashed by some other element in the website. Could have been WP or one of the few plug ins I could not remove as it is the page builder (Elementor, Elementor Essentials). After disabling all the other plug ins it is narrowed down to that. The code solution was: ....
jQuery(document).on('submit', '#ajax-add-to-waitlist-form', function(e){
e.preventDefault();
.......
Instead of
jQuery('#ajax-add-to-form').on('submit', function(e){
e.preventDefault();

e.preventDefault();before anything else on thejQuery('#ajax-add-to-form').on('submit', function(e){function. Let me know if works. – Celso Bessa Commented Jan 4, 2021 at 21:19
