How to prevent adding double input with onclick button

Hi guys so when I try to add a question and answers this code works. But if I have made 2 questions and want to add a answer it will put an extra "answer" field in BOTH of the question. But ofcourse I only want to add an answer field to the "question" button i clicked on
var question = 0;
function add_question() {
question++;
var allquestions = document.getElementById('all_questions')
var divquestion = document.createElement("div");
divquestion.innerHTML = `
<div id="all_questions">
<div class="form-group">
<label for="question" class="col-form-label">Question `+ question + `:</label>
<div class="input-group">
<div class="input-group-prepend"><span class="input-group-text"><i class="fas fa-question"></i></span></div>
<input type="text" class="form-control" name="question">
</div>
</div>
<div class="form-group mx-5">

</div>
<div id="all_answers">
</div>
<button type="button" class="btn btn-success m-1" onclick="add_answer()">add answer</button>
<hr>
</div>
`;
allquestions.appendChild(divquestion)
}
var answer = 2;
function add_answer() {
answer++;
var allanswers = document.getElementById('all_answers')
var divanswer = document.createElement("div");
divanswer.innerHTML = `

If something is unclear I will try to explain it.
Please dont be to harsh I am pretty new to javascript...

All you needed to do was specify in your questions container an ID for where to put your answers in your add answer function i just used the question increment as an id and added that to the <div id="all_answers_${id}"> id and passed the id in the click function onclick="add_answer(${id})".
var question = 0;
function add_question() {
question++;
var allquestions = document.getElementById('all_questions')
var divquestion = document.createElement("div");
var id = question;
divquestion.innerHTML = `
<div id="all_questions">

Jquery Ajax POST is not getting dynamically added inputs inputs have names and I have tried other solutions

Ajax Post request is only getting the first of the dynamically added input fields at the bottom all others are ignored
I have tried .on() .live() .submit() functions but get the same result. My php file consists of a print_r($_POST); and nothing else this is put into the console.
https://pastebin.com/CuAPSzKe - I have put the full code on the pastebin as the whole table and the script used to add the new inputs is included.
This is the code to make the call:
$('input#submitButton').on('click', function(e) {
e.preventDefault(); // avoid to execute the actual submit of the form.
var form = $('form#orderForm');
var url = form.attr('action');
$.ajax({
type: "POST",
url: url,
data: form.serialize(), // serializes the form's elements.
success: function(data)
{
console.log(data);
}
});
});
My expected result is to be able to post all dynamically added fields with their names as an array, alternatively all dynamically added fields in their own array.

It is having a major issue due to the way your html is arbitrarily structured and you are missing a end div tag for your item information container. Fix these issues and it will run. You also may want to go ahead and start your first item information with a start of 0 and set your counter to 1 so it is easier to aparse on the backend once you recieve the info.
Move your form tag under your first container:
<div class="container">
<form id="orderForm" method="POST" action="test.php">
<h2>Address Information</h2>
End tag
<input type="submit" id="submitButton" name="submitButton" value="Submit">
</div>
</div>
</form>
</div>
Full example of cleaned up code running:
function test() {
var billName = document.getElementById('bill_name');
var shipName = document.getElementById('ship_name');
var billLine1 = document.getElementById('bill_line_1');
var shipLine1 = document.getElementById('ship_line_1');
var billLine2 = document.getElementById('bill_line_2');
var shipLine2 = document.getElementById('ship_line_2');
var billLine3 = document.getElementById('bill_line_3');
var shipLine3 = document.getElementById('ship_line_3');
var billLine4 = document.getElementById('bill_line_4');
var shipLine4 = document.getElementById('ship_line_4');
var billCounty = document.getElementById('bill_county');
var shipCounty = document.getElementById('ship_county');
var billPostcode = document.getElementById('bill_post');
var shipPostcode = document.getElementById('ship_post');
var billTele = document.getElementById('bill_telephone');
var shipTele = document.getElementById('ship_telephone');
var billEmail = document.getElementById('bill_email');
var shipEmail = document.getElementById('ship_email');
shipName.value = billName.value;
shipLine1.value = billLine1.value;
shipLine2.value = billLine2.value;
shipLine3.value = billLine3.value;
shipLine4.value = billLine4.value;
shipCounty.value = billCounty.value;
shipPostcode.value = billPostcode.value;
shipTele.value = billTele.value;
shipEmail.value = billEmail.value;
}
$('input#submitButton').on('click', function(e) {
e.preventDefault(); // avoid to execute the actual submit of the form.
var form = $('form#orderForm');
var url = form.attr('action');
var test = form.serialize();
alert(test);
});
$(document).ready(function () {

This isn't going to solve your problem, but here's a snippet where I commented out the bits that weren't working. Try putting a snippet like this into your question, with the things you need, and you'll be able to see what is and isn't working. You can also use https://codepen.io/ to build these things out and test more.
Consider using something other than jQuery, as it's pretty old these days!
create-react-app is a nice starting point if you want to try react.
Writing validation libraries from scratch is a huge task, there are so many tools and plugins now you can use to avoid starting from the ground up:
for jquery: https://jqueryvalidation.org/
for react some insight:
https://www.telerik.com/blogs/up-and-running-with-react-form-validation
If you're just doing this for the joy of learning how to solve this problem with jQuery, that's cool! Feel free to comment on this answer and I'll update it to try and help you. Here's the snippet example for your reference:
$("#book").click(function() {
var data = {
totalamount: document.getElementById('etamt').innerHTML,
venue: document.getElementById('cvenue').innerHTML,
email: $('#cvemail').val(),
// de: document.getElementById('des').innerHTML,
// oname: document.getElementById('coname').innerHTML,
name: document.getElementById('ctitle').innerHTML,
// frdate: document.getElementById('cedate').innerHTML,
// todate: document.getElementById('ctodate').innerHTML,
// byno: $('#buynumber').val(),
// byemail: $('#buymail').val(),
// byname: $('#buyname').val(),
// num: document.getElementById('etqty').innerHTML,
}
$.ajax({
async: true,
url: "eventdetail.php",
method: "POST",
data: $(data).serialize(),
// $('.eventdetail').serialize(),
success: function(rt) {
}
});
console.log(data);
});

PS:- I should only do this in angular r javascriprt r bootstrap way thanks in advance
Edit :- Is there anyone can do this?

I solved my issue by adding in my signup component
<div *ngIf="hide"> //at the top
<div class="modal-content" id="register" style="padding: 20px;">
<div *ngIf="show"> //at the bottom
<app-sign-in></app-sign-in>
</div>
adding a click function to the button
<p>Already have an account? <button type="button" (click)="signin()">Sign In</button></p>
in the ts file making show = true and hide= false when required like below
export class SignUpComponent implements OnInit {
show = false;
hide = true;
signin(){
this.hide=false;
this.show=true;
}
}

Form.Serialize with checkbox array

I'm submitting a form through JQuery by using the form.serialize method. But that same form has an array of checkboxes, which is dynamically genetrated by a PHP function
This is the form:
<form class="form" id="formNewClient" role="form">
<ul class="nav nav-tabs">
<li class="active"><i class="fa fa-user"></i> Dados Cliente</li>
<li><i class="fa fa-phone"></i> Dados Phonepark</li>
</ul>

<button type="button" class="btn btn-danger" data-dismiss="modal"><i class="fa fa-times"></i> Cancelar</button>
</div>
</div>
</form>
And this is the php function that generates the checkboxes:
function profileCheckBoxes(){
$queryListProfiles = "SELECT * FROM perfil";
$listProfiles = mysqli_query($GLOBALS['dbc'],$queryListProfiles);
$numProfiles = mysqli_num_rows($listProfiles);
if($numProfiles !=""){
while($row = mysqli_fetch_array($listProfiles)){
?>
<label class="checkbox-inline">
<input type="checkbox" value="<?php echo $row['id']?>" name="profiles[]">
<?php echo $row['Nome']; ?>
</label>
<?php
}
}
}
How can I submit the form with form.serialize in Jquery and in the PHP side process the checkbox so I can extract the values from the checkbox array?

This jQuery documentation page explains how to use the serialize function:
http://api.jquery.com/serialize/
If you then pass the output to your php page using POST, in the PHP script the checked values will be stored in $_POST['profiles'] as an array. So to loop through the values of the checked boxes you could use:
foreach ($_POST['profiles'] as $profile) {
//process code here
}

jQuery's form.serialize only pass checksboxes that are checked.
if you want all your checkboxes to get passed to your server consider to generate also hidden inputs to store those values.
I would also change the checkboxes name to "profiles"
