How to dynamically add form elements in jquery?

I'm trying to created a dynamic form in rails with a little bit of javascript I have a problem I only get one row in the output when using pry apparently it's because I have the same params for every field input since I use jQuery .clone, maybe someone has struggled with something similar can share some knowledge, how to dynamically add index to params in this form with javascript ?
#extends('Admin.master')
#section('content')
<div class="p-5">
<h3><i class="fas fa-cog ml-2"></i>Setting</h3><hr>
<form action="{{ route('settings.update', $setting->id) }}" method="POST" >
#csrf
#method('PUT')
<div id="showDynamic">
</div>
</form>
</div>
#endsection
#section('script')
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
let count = 1;
$('.add').click(function(){
count++;
dynamic(count);
});
dynamic(count);
function dynamic(number) {
var html = '' +
'<div class="row">\n' +
'<div class="col-md-4">\n' +
'<input class="form-control" placeholder="Name">\n' +
'</div>\n' +
'<div class="col-md-4">\n' +
'<input class="form-control" placeholder="Link">\n' +
'</div>\n' +
'<div class="col-md-2">\n' +
'<a class="btn btn-primary" id="add">Add</a>\n' +
'<a class="btn btn-danger" id="delete">Delete</a>\n' +
'</div>\n' +
'</div>';
$('#showDynamic').append(html);
}
});
</script>
#endsection

1st id must be unique .. So change id="add" and id="delete" to classes class="btn btn-primary add"
2nd event-binding-on-dynamically-created-elements After changing the id to class use $(document).on('click' , '.add' , function(){ //code here })
Your code should be
<script>
$(document).ready(function(){
let count = 1;
$(document).on('click' , '.add' , function(){
count++;
dynamic(count);
});
dynamic(count);
function dynamic(number) {
var html = '' +
'<div class="row">\n' +
'<div class="col-md-4">\n' +
'<input class="form-control" placeholder="Name">\n' +
'</div>\n' +
'<div class="col-md-4">\n' +
'<input class="form-control" placeholder="Link">\n' +
'</div>\n' +
'<div class="col-md-2">\n' +
'<a class="btn btn-primary add">Add</a>\n' +
'<a class="btn btn-danger delete">Delete</a>\n' +
'</div>\n' +
'</div>';
$('#showDynamic').append(html);
}
});
</script>
$(document).ready(function(){
let count = 1;
$(document).on('click' , '.add' , function(){
count++;
dynamic(count);
});
dynamic(count);
function dynamic(number) {
var html = '' +
'<div class="row">\n' +
'<div class="col-md-4">\n' +
'<input class="form-control" placeholder="Name">\n' +

'<div class="col-md-4">\n' +
'<input class="form-control" placeholder="Link">\n' +
'</div>\n' +
'<div class="col-md-2">\n' +
'<a class="btn btn-primary add">Add</a>\n' +
'<a class="btn btn-danger delete">Delete</a>\n' +
'</div>\n' +

After creating a batch of Html nodes, The link does not work!
How can I fix it?
Javascript Codes:
var nnn = '<div class="media mt-3 w-100" id="commentNode_0000">' +
'<a class="pr-0" href = "#" >' +
'<img class="mr-3" src="/images/comment1.png" alt="x">' +
'</a>' +
'<div class="media-body w-100">' +
'<h5 class="mt-0 mb-1">User</h5>' +
'<div id="collapse_0000" class="">' +
'<div id="cardId_0000" class="card">' +
'<p>TEST TEST</p>' +
'</div>' +
'<div class="comment-meta" id="commentId_0000">' +
'<span><input id="deleteC_24_20" type="submit" class="submitLink" value="delete"></span>' +
'<span><input id="editC_24_20" type="submit" class="submitLink" value="edit"></span>' +
'<span>' +
'<a id="replyC_24_20" class="" role="button" data-toggle="collapse" href="#replyComment_0000" aria-expanded="false" aria-controls="collapseExample">reply</a>' +
'</span>' +
'<div id="replyComment_0000" class="collapse"></div>' +
'</div>' +
'</div>' +
'</div>' +
'</div>';
$(collapseId).append(nnn);
Exactly this line of code:
'<a id="replyC_24_20" class="" role="button" data-toggle="collapse" href="#replyComment_0000" aria-expanded="false" aria-controls="collapseExample">reply</a>'
I expect this event to fire after clicking the tag that I have created dynamically.
But it doesn't work!
$("a[id^='replyC_']").on("click", function (event) {
var nodeId = event.target.id;
});

var collapseId = document.getElementById('collapseId')
var nnn = '<div class="media mt-3 w-100" id="commentNode_0000">' +
'<a class="pr-0" href = "#" >' +
'<img class="mr-3" src="/images/comment1.png" alt="x">' +
'</a>' +
'<div class="media-body w-100">' +
'<h5 class="mt-0 mb-1">User</h5>' +
'<div id="collapse_0000" class="">' +
'<div id="cardId_0000" class="card">' +
'<p>TEST TEST</p>' +
'</div>' +
'<div class="comment-meta" id="commentId_0000">' +
'<span><input id="deleteC_24_20" type="submit" class="submitLink" value="delete"></span>' +
'<span><input id="editC_24_20" type="submit" class="submitLink" value="edit"></span>' +
'<span>' +
'<a id="replyC_24_20" class="" role="button" data-toggle="collapse" href="#replyComment_0000" aria-expanded="false" aria-controls="collapseExample">reply</a>' +
'</span>' +
'<div id="replyComment_0000" class="collapse"></div>' +
'</div>' +
'</div>' +
'</div>' +
'</div>';
$(collapseId).append(nnn);
$("a[id^='replyC_']").on("click", function (event) {
var nodeId = event.target.id;
console.log(nodeId);
});
<div id="collapseId"></div>

it works fine :)

Remove DIV dynamically with JQuery

i have a problem to reference an identifier of a DIV. I allow to add a div with a text field and a button to delete the text field, and i set a id to the DIV like an array with this code:
$('#aggiungi').on('click',function () {
$count ++;
$('#corsi').append(
'<div class="form-group row" id="corso['+$count+']>' +
'<label class="col-sm-2 col-form-label" for="corsi">Corso ' + $count +'</label>' +
'<div class="col-sm-10 form-inline">' +
'<input type="text" class="form-control" id="corso" name="corso['+ $count + ']"/>' +
'<a class="btn btn-default" id="eliminacorso['+$count+']" aria-label="Elimina">' +
'<i class="fa fa-times" aria-hidden="true"></i>' +
'</a>' +
'</div>' +
'</div>' +
'');
});
So.. if i press on the botton at the at the side of the text area, i'll call a function that will remove it.
The skeleton of the function is the follow:
$('#eliminacorso[]').on('click', function() {
$count --;
$('#corso[]').remove();
});
So my ask is: How can i insert between the square brackets the right identifier of the div?

A better choice is:-
1.Instead of using id use button class
2.And then use event delegation concept like below:-
$(document).on('click','.btn-default',function(){
$(this).closest('.form-group').remove();
});
Reference:- https://api.jquery.com/closest/

Use as below the script that add DIV. Remove '[' from id attribute from div tag and anchor tag as below
$('#aggiungi').on('click',function () {
$count ++;
$('#corsi').append(
'<div class="form-group row" id="corso'+$count+'>' +
'<label class="col-sm-2 col-form-label" for="corsi">Corso ' + $count +'</label>' +
'<div class="col-sm-10 form-inline">' +
'<input type="text" class="form-control" id="corso" name="corso['+ $count + ']"/>' +
'<a class="btn btn-default" id="corso'+$count+'" aria-label="Elimina">' +
'<i class="fa fa-times" aria-hidden="true"></i>' +
'</a>' +
'</div>' +
'</div>' +
'');
});
And then script to get the clicked id and remove the matched div on click of button as below
$('.btn').on('click', function() {
var selectedId = $(this).attr('id');
$('#'+selectedId).remove();
});

Try below code.It may help you
var $count =0
$('#aggiungi').on('click',function () {
$count ++;
$('#corsi').append(
'<div class="form-group row" id="corso_'+$count+'">' +
'<label class="col-sm-2 col-form-label" for="corsi">Corso ' + $count +'</label>' +
'<div class="col-sm-10 form-inline">' +
'<input type="text" class="form-control" id="corso" name="corso_'+ $count + '"/>' +
'<a class="btn btn-default" id="eliminacorso_'+$count+'" aria-label="Elimina" onclick="remove(this);">' +
'Test' +
'</a>' +
'</div>' +
'</div>' +
'');
});
function remove(aRemove){
console.log(aRemove);
var divid = aRemove.id.replace("eliminacorso_","corso_");
$("#" + divid).remove();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="aggiungi"> Click ME </button>
<div id="corsi">
</div>

https://codepen.io/vino4all/pen/vZrQEX
Try this code.
<button id="aggiungi">Click</button>
<div id="corsi"></div>
Add a class attribute to the <a> tag.
var $count = 0;
$('#aggiungi').on('click',function () {
$count ++;
$('#corsi').append(
'<div class="form-group row" id="corso['+$count+']>' +
'<label class="col-sm-2 col-form-label" for="corsi">Corso ' + $count +'</label>' +
'<div class="col-sm-10 form-inline">' +
'<input type="text" class="form-control" id="corso" name="corso['+ $count + ']"/>' +
'<a class="btn btn-default delBtn" id="eliminacorso['+$count+']" aria-label="Elimina"><span>X</span>' +
'<i class="fa fa-times" aria-hidden="false"></i>' +
'</a>' +
'</div>' +
'</div>' +
'');
});
$('#corsi').on('click', '.delBtn', function() {
console.log('this :'+$(this));
$count --;
$(this).parent().parent().remove();
});
Notice the usage of on function.
It should be like below
$('#corsi').on('click', '.delBtn', fun);

You can use something like this
var count = 3;
$('button').click(function(){
count--;
$($('.corso')[count]).remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="corso">1. <input type="text" /></div><br />
<div class="corso">2. <input type="text" /></div><br />
<div class="corso">3. <input type="text" /></div><br />
<br />
<button>Remove</button>

Try this:
var $count = 0
$('#aggiungi').on('click', function () {
$count++;
let divId = `input_div_${$count}`;
let html = `<div class="form-group row" id="${divId}">
<label class="col-sm-2 col-form-label" for="corsi">Input ${$count}</label>
<div class="col-sm-10 form-inline">
<input type="text" class="form-control" id="input" name="${divId}"/>
<button type="button" id="remove_btn_${$count}" aria-label="Elimina" onclick="remove('${divId}');">
remove
</a>
</div>
</div>`;
$('#main-div').append(html);
});
function remove(removeDivId) {
console.log(removeDivId);
$("#" + removeDivId).remove();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" id="aggiungi"> Click ME </button>
<div id="main-div">
</div>

Adding Dynamic Inputs , getting value from Dynamic dynamic generate input

I created a dynamic Form with JavaScript, with AddChapitre function and I want to get number value from an input text <input type="text" class="form-control" id="grandTitreNbr1">. And created "numbers value" inputs when I click to addChapitre button using AddFeild() function <button id="b1" class="btn btn-primary" onclick="addFields()">add titres</button> .
The problem is when I click in addChapitre I get the The Chapitre Form hidden.
Here is it in JsFiddle : http://jsfiddle.net/javagose/6veqe55v/1/
This image will show the problem:
function addChapitre() {
var newdiv = document.createElement('div');
var addChapitre =
'<div class="panel panel-success"> <div class="panel-heading"> <h2 class="panel-title">' +
'<a data-toggle="collapse" data-target="#collapse" href="#collapse" class="collapsed">chapitre : ' + j +
' </a></h2></div><div class="panel-body" id="Chapitre' + j + '">';
newdiv.innerHTML += addChapitre;
addChapitre1 =
'<div class="panel-collapse" id="collapse' + j + '" >' +
'<form class="form-horizontal"><div class="form-group">' +
'<label for ="ChapTitre' + j + '">Titre du chapitre</label>' +
'<input type="text" class="form-control" id="ChapTitre' + j +
'" placeholder=" titre du chapitre ' + j + '"></div></form></div>';
newdiv.innerHTML += addChapitre1;
addChapitre2 =
'<div class="panel panel-success" id="grandTitres' + j + '">' +
'<div class="panel-heading"><h2 class="panel-title">' +
'<a data-toggle="collapse" data-target="#collapseTitre" ' +
'href="#collapseTitre" class="collapsed"> Grands titres des chapitre: ' + j + '</a></h2></div>';
newdiv.innerHTML += addChapitre2;
addChapitre2 =
'<div class="panel-body"><div class="panel-collapse" id="collapseTitre" >' +
'<form class="form-horizontal"><div class="form-group" id ="grandTitres1">' +
'<label for ="grandTitreNbr1"> GRAND TITRE</label>' +
'<input type="text " class="form-control" id="grandTitreNbr' + j + '">' +
'<button id="b1" class="btn btn-primary" onclick="addFields()">add titres</button>' +
'<div id="grandTitresDiv' + j + '">' +
'</div></div> </form></div></div> </div></div></div>';
newdiv.innerHTML += addChapitre2;
document.getElementById('conteneur').appendChild(newdiv);
j++;
}
function addFields() {
var number = document.getElementById("grandTitreNbr" + j + "").value;
var container = document.getElementById("grandTitresDiv" + j + "");
for (i = 0; i < number; i++) {
// Append a node with a random text
var newdiv = document.createElement('div');
var grandTitreTxt =
'<input type="text" class="form-control" id="grandTitreTxt' + j +
'" name="grandTitreTxt' + j + '"></div>';
newdiv.innerHTML += grandTitreTxt;
var grandTitreUpload =
'<div class="checkbox"><label><input type="checkbox"> Pdf </label></div>' +
' <input type="file" name="fichier" id="fichier"' + j + ' accept="pdf" />';
newdiv.innerHTML += grandTitreUpload;
var grandTitreUpload =
'<div class="checkbox"><label><input type="checkbox">video </label>' +
'</div> <input type="file" name="fichier" id="fichier"' + j +
' accept="video" />';
newdiv.innerHTML += grandTitreUpload;
container.appendChild(newdiv);
// Append a line break
container.appendChild(document.createElement("br"));
}
}

document.getElementById is returning null on the button click

I have a textarea and a button. The button submits the data to a page through AJAX through a function. When the button is clicked it calls a function that takes in 3 parameters for this question only one of them is necessary.
Let's look at the code to understand more clearly:
var offers = <? php echo PostOffer::GetOffers($_GET["id"]); ?> ;
for (var i = 0; i < offers.length; i++) {
var date = offers[i].Date.split(" ");
document.write('<div class="row-fluid offer">' +
'<div class="span2">' +
'<img class="profile_picture" src="' + offers[i].Picture_Path + '" />' +
'</div>' +
'<div class="span10">' +
'<div class="row-fluid">' +
'<div class="username">' +
'<p style="font-weight: bold;">' + offers[i].Name + '</p>' +
'</div>' +
'</div>' +
'<div class="row-fluid">' +
'<div class="content">' +
'<p class="content">' + offers[i].Text + '</p>' +
'<textarea class="hide span12" id="edited_content">' + offers[i].Text + '</textarea>' +
'<button type="button" class="hide btn btn-primary btn-small" id="save_edits" onclick=\'editPostOffer("<?php echo $_GET["id"]; ?>","' + offers[i].Offer_ID + '","' + document.getElementById("edited_content") + '");\'>Save Edits</button> ' +
'<button type="button" class="hide btn btn-primary btn-small cancel_edits">Cancel Edits</button>' +
'</div>' +
'</div>' +
'<div class="row-fluid">' +
'<div class="date">' +
'<p class="pull-right"><strong><span class="muted">Offered on: </span></strong>' + date[0] + '</p>' +
'</div>');
if (offers[i].Username == "<?php echo $_SESSION["
username "]; ?>") {
document.write('<div class="controls pull-right">' +
'Edit ' +
'Delete | ' +
'</div>');
}
document.write('</div>' +
'</div>' +
'</div>' +
'<hr />');
}
The important part is:
...
'<div class="row-fluid">' +
'<div class="content">' +
'<p class="content">' + offers[i].Text + '</p>' +
'<textarea class="hide span12" id="edited_content">' + offers[i].Text + '</textarea>' +
'<button type="button" class="hide btn btn-primary btn-small" id="save_edits" onclick=\'editPostOffer("<?php echo $_GET["id"]; ?>","' + offers[i].Offer_ID + '","' + document.getElementById("edited_content") + '");\'>Save Edits</button> ' +
'<button type="button" class="hide btn btn-primary btn-small cancel_edits">Cancel Edits</button>' +
'</div>' +
'</div>' +
...
The most important is:
...
'<button type="button" class="hide btn btn-primary btn-small" id="save_edits" onclick=\'editPostOffer("<?php echo $_GET["id"]; ?>","' + offers[i].Offer_ID + '","' + document.getElementById("edited_content") + '");\'>Save Edits</button> ' +
...
In the onclick of that button the function document.getElementById("edited_content") returns a null value. I've tried logging it to the console it prints null. Why is that happening?
Any help would be appreciated!

Because at the point you call document.getElementById("edited_content"), edited_content does not exist.
You are creating it by appending a string, so you'd need to do something like:
// Add the first part
document.write('<div class="row-fluid offer">' +
'<div class="span2">' +
'<img class="profile_picture" src="' + offers[i].Picture_Path + '" />' +
'</div>' +
'<div class="span10">' +
'<div class="row-fluid">' +
'<div class="username">' +
'<p style="font-weight: bold;">' + offers[i].Name + '</p>' +
'</div>' +
'</div>' +
'<div class="row-fluid">' +
'<div class="content">' +
'<p class="content">' + offers[i].Text + '</p>' +
'<textarea class="hide span12" id="edited_content">' + offers[i].Text + '</textarea>');
// Now we can get edited_content
document.write('<button type="button" class="hide btn btn-primary btn-small" id="save_edits" onclick=\'editPostOffer("<?php echo $_GET["id"]; ?>","' + offers[i].Offer_ID + '","' + document.getElementById("edited_content") + '");\'>Save Edits</button> ');
// Write the rest of the HTML
document.write('<button type="button" class="hide btn btn-primary btn-small cancel_edits">Cancel Edits</button>' +
'</div>' +
'</div>' +
'<div class="row-fluid">' +
'<div class="date">' +
'<p class="pull-right"><strong><span class="muted">Offered on: </span></strong>' + date[0] + '</p>' +
'</div>');
P.S. You tagged the question with jQuery - there are much better ways of doing what you are trying to achieve. Better still, use a templating engine.
