Issue on getting id from Selected HTML elements from Ajax GET response with jQuery

I am using ajax to display product data and then delete on click a specific on using the product id but am not able to get the product id as it is showing undefine can you guys suggest something.
In this code first I am getting the product details for the cart dropdown menu and then displaying it in list format with delete button through the first ajax and then on clicking delete should delete the element in the second ajax using the elements product id which I have saved inside data-r but on console, it showing undefined can anyone tell me what is the issue. As I know that the elements are created dynamically but I am not getting a solution
function TopCartVal() {
// Used Route inside the ajax
var url = "{{ route('pdt.details', ':id') }}";
var yui = "{{ route('delete_fr.cart', ':id') }}";
// Ajax Structure
$.getJSON( "{{ route('my.cart','json') }}", function( data ) {
console.log(data);
var Cart = $('#cart_dp_sec_pdt_desc');
// Loop for data
$.each(data, function(key , value) {
console.log(value);
url = url.replace(':id', value.product_id);
yui = yui.replace(':id', value.product_id);
Cart.append(`
<div class="row">
<div class="col-xs-4">
<div class="image">
<a href="`+url+`">
<img src="{{ asset('')}}`+value.image+`" alt=""/>
</a>
</div>
</div>
<div class="col-xs-7">
<h3 class="name">
`+value.product_name+`
</h3>
<div class="price">`+value.currency+value.product_price+`</div>
</div>
<div class="col-xs-1 action">
<a href="#"
data-r"`+value.id+`"
class="cart_dp_btn_ctn_delete">
<i class="fa fa-trash"></i>
</a>
</div>
</div>
`);
});
});
}
// delete part
$(document).on('click', '.cart_dp_btn_ctn_delete', function(e){
e.preventDefault();
var id = $(this).attr('data-r'); // id of to be deleted element
var yui = "{{ route('delete_fr.cart', ':id') }}";
yui = yui.replace(':id', id);
console.log(yui);
console.log(id); // it is showing undefined`enter code here`
// $.getJSON( yui, function(data){
// TopCartVal();
// });
});

You are missing an = here:
data-r"`+value.product_id+`"
But using template literals correctly will make it easier to see
`<div class="row">
<div class="col-xs-4">
<div class="image">
<a href="${url">
<img src="{{ asset('')}}${value.image}" alt=""/>
</a>
</div>
</div>
<div class="col-xs-7">
<h3 class="name">
${value.product_name}
</h3>
<div class="price">${value.currency+value.product_price}</div>
</div>
<div class="col-xs-1 action">
<a href="#" data-r="${value.product_id}" class="cart_dp_btn_ctn_delete">
<i class="fa fa-trash"></i>
</a>
</div>
</div>`

Understanding Ajax and adding cart count

website: https://www.fermento24.com
If you add a product to the cart, it'll show you the recently added product, total and possibility to go to cart. What I wanted to add was a count of the sort, like: There are currently another 5 products in the cart.
I tried to use {{ cart.item_count }}, but since the popup works on Ajax it doesn't seem to update on time, only showing me at the first time how many products were in the cart (thus, incorrect informations).
How do I go and implement something like this? What follows under is a test I did based on other answers I found here, but that still didn't work.
<div class="loading-modal modal">{{ 'general.search.loading' | t }}</div>
<div class="newsletter-success-modal">
<div class="modal-overlay"></div>
<div class="ajax-modal-content">
<a class="close close-window btn" title="{{ 'general.password_page.close' | t }}">
<i class="fa fa-times"></i>
</a>
<i class="fa fa-check" aria-hidden="true"></i>
<span>{{ 'general.newsletter_form.mailing_list_success_message' | t }}</span>
</div>
</div>
<div class="ajax-error-modal modal">
<div class="modal-inner">
<div class="ajax-error-title">{{ 'general.search.error' | t }}</div>
<div class="ajax-error-message"></div>
</div>
</div>
<div class="ajax-success-modal modal">
<div class="overlay"></div>
<div class="content">
<div class="ajax-left">
<p class="added-to-cart info">{{ 'cart.general.added_to_cart' | t }}</p>
<p class="added-to-wishlist info">{{ 'products.wishlist.added_to_wishlist' | t }}</p>
<img class="ajax-product-image" alt="modal window" src="/" />
<div class="ajax-cart-desc">
<h3 class="ajax-product-title"></h3>
<span class="ajax_price"></span>
<p>{{ 'cart.general.qty' | t }}: <span class="ajax_qty"></span></p>
</div>
</div>
<div class="ajax-right">
<div>Totale nel carrello: <span class="ajax_cartTotal"></span><br>
<span class="cart-item-count"> </span>
</div>
<button class="btn continue-shopping" onclick="javascript:void(0)">{{ 'cart.general.continue_shopping' | t }}</button>
<div class="success-message added-to-cart"><i class="fa fa-shopping-cart"></i>{{ 'cart.general.view_cart' | t }} </div>
</div>
<i class="fa fa-times-circle"></i>
</div>
</div>
<script type="text/javascript">
$(function(){
var cartCount = {{ cart.item_count }};
$('.varients-item').on('click', function(){
var obj = $(this);
$.ajax({
type: 'POST',
url: '/cart/add.js',
data: {
quantity: 1,
id: $(this).attr("data-variant")
},
dataType: 'json',
success: function (data) {
$.ajax({
type: 'GET',
dataType: 'json',
url: '/cart.json',
success: function(cart){
cartCount++;
$('.cart-item-count').html(cartCount);
}
});
}
});
});
});
</script>

You need to update the code and your JS code is looks like similar to demo code below:
$(function(){
$('.varients-item').on('click', function(){
var obj = $(this);
$.ajax({
type: 'POST',
url: '/cart/add.js',
data: {
quantity: 1,
id: $(this).attr("data-variant")
},
dataType: 'json',
success: function (data) {
$.ajax({
type: 'GET',
dataType: 'json',
url: '/cart.js',
success: function(cart){
// once you get the data from AJAX API you need to get the latest count
let total = cart.item_count;
$('.cart-item-count').html(total);
}
});
}
});
});
});
Here is the reference for the cart.js over Shopify documentation.

How to identify multiple forms in one template?

I'm trying to implement a follower/following system in Django. In the template, all follow requests have a user and they all have user id's that can be displayed. The template is a profile page that contains several follow requests made by other users. I have created a separate form for each accept/decline and I want to uniquely identify each form so that I can submit that one and remove it subsequently.
<div class="col s12 l6 trending-panel container">
<h4>
Requests
</h4>
<div class="divider"></div>
{% for bond_request in bond_requests %}
{% if bond_request.accepted == False %}
<div>
<div class="row bond-request-row" id="{{bond_request.by_user.id}}">
<div class="col s6">
<a href="{% url 'accounts:profile' bond_request.by_user.username %}">
<div class="col s8">
<img class="profile-image-request" src="https://m.media-amazon.com/images/M/MV5BNjUxNDcwMTg4Ml5BMl5BanBnXkFtZTcwMjU4NDYyOA##._V1_.jpg" alt="">
</div>
<div class="col s4">
<h6 id="follower-username">
#{{bond_request.by_user}}
</h6>
</div>
</a>
</div>
<div class=" col s12 center accept-decline-margin">
<div class="col s12 l6">
<form action="accounts:accept_bond_request" method="POST" id="bond-request-accept-form">
<!-- <a href="#" id="bond-request-accept" class="green-text white btn">
<div>
<ion-icon name="add"></ion-icon>
<span>Accept</span>
</div>
</a> -->
<button id="bond-request-accept" class="green-text white btn" type="submit">Accept</button>
</form>
</div>
<div class="col s12 l6">
<a href="" class="grey-text white btn">
<div class="">
<ion-icon name="remove"></ion-icon>
<span>Ignore</span>
</div>
</a>
</div>
</div>
</div>
<!-- HERE -->
</div>
{% else %}
{% endif %}
<div class="divider">
</div>
{% endfor %}
</div>
$("#bond-request-accept-form").on('submit',function(){
// Cleans the username
// var each_bond_request = $();
var raw_follower_username = $("#follower-username").text().trim();
var follower_username = raw_follower_username.replace("#","");
console.log("Follower username: ",follower_username);
$.ajax({
type: "POST",
url: "/accounts/user/" + follower_username + "/accept_request",
data:{
"follower_username" : follower_username,
},
success: function(data){
console.log(data);
M.toast({html: follower_username + ' started following you',classes: 'green'}, );
},
error: function(data){
console.log("All error data: ",data);
M.toast({html: 'Failure',classes: 'red'}, );
},
});
});

You should create a standalone function to handle submit. And reference this function in each form you created.
function SubmitHandler (e) {
// Cleans the username
// var each_bond_request = $();
var raw_follower_username = $(e).find("#follower-username").text().trim();
var follower_username = raw_follower_username.replace("#","");
console.log("Follower username: ",follower_username);
$.ajax({
type: "POST",
url: "/accounts/user/" + follower_username + "/accept_request",
data:{
"follower_username" : follower_username,
},
success: function(data){
console.log(data);
M.toast({html: follower_username + ' started following you',classes: 'green'}, );
},
error: function(data){
console.log("All error data: ",data);
M.toast({html: 'Failure',classes: 'red'}, );
},
});
return false;
}
Then in your template:
...
<form id="bond-request-accept-form" onsubmit="SubmitHandler(this)">
...
Note the #follower-username should be nested within the form tag for jQuery to find the correct one.

First, I just want to say that I may be understanding your question wrong. If so, feel free to correct me.
If I am understanding this right, you have multiple copies of essentially the same form with slight variations depending on the user that is sending the request. Since IDs are meant to be unique and can cause issues in JavaScript if there are more than one instance of them, I would change the bond-request-accept-form to a class rather than an ID, and do something like this in JQuery:
$(".bond-request-accept-form").toArray().forEach(function(elem){
$(elem).on('submit', function(){
// Logic to perform when the form is submitted
});
});

Put different URLs in the action for the two forms. Then you'll have two different view functions to deal with the two different forms.

jquery on click no working on EDIT button

I'm developing CMS. Issue is that jquery on click no working on EDIT Button. Code seems fine to me but I did not understand why it is not working. It is working on Add Button.

Note: - I'm using jQuery 1.11.3

You can only use an ID once, since it has to be unique.

The issue is happening because of same ids.
Replace
$('.edit').on('click',function()
with
$(document).on('click', '.edit', function()

TinyMCE not being added to element on AJAX call

I'm having some issues applying TinyMCE onto the textarea element.
I have a page with a list of passengers. When you click a passsenger, AJAX is called and it displays info for the passenger, one field which happens to be a textarea element. My problem is that the first passenger (any passenger) you click on loads TinyMCE, but from here on out, it's just a normal textarea with no TinyMCE applied. I don't know what's happening. Here is the following code I have:
j$ = jQuery.noConflict();
j$(document).ready(function(e) {
tinyMCE.init({
mode : "textareas",
theme : "advanced",
theme_advanced_buttons1 : "bold, italic, underline, | ,bullist, numlist, | ,outdent, indent, | ,link, unlink, |, code",
relative_urls : false,
remove_script_host : false,
});
j$('.names strong').click(function(e) {
//Find passenger ID
var customer_ID = j$(this).closest('.passenger_Container').find("input[name='customer_ID']").val();
//Find placement of returned data
var insert_Data = j$(this).closest('.passenger_Container').find('.package');
j$.ajax({
type: "POST",
url: "/include/passenger_Detail.php",
data: { customer_ID_Data : customer_ID },
success: function(data) {
//get returned data and add into appropriate place
insert_Data.html(data);
var oldEditor = tinyMCE.get('notes');
if (oldEditor != undefined) {
tinymce.remove(oldEditor);
}
tinyMCE.execCommand('mceAddControl', false, 'notes');
//re-initialise WYSIWYG editor. Notes is the ID to re-initialize
/*tinymce.execCommand('mceRemoveControl',true,'notes');
tinymce.execCommand('mceAddControl',true,'notes');*/
}
});
});
});
<!-- content is displayed using PHP while loop -->
<div class="passenger_Container bottom-buffer">
<div class="names row">
<div class="col-xs-1 text-center">
<!-- Display checkbox -->
</div>
<div class="col-xs-4 col-sm-3">
<strong><?php echo $row['f_Name'].' '.$row['l_Name']; ?></strong> </div>
<div class="col-xs-3 hidden-xs">
<!-- display child names -->
</div>
<div class="col-xs-3">
<!-- Display order status -->
</div>
<div class="col-xs-1 col-sm-2">
<!-- Display form -->
</div>
</div>
<div class="package custom-well well-sm top-buffer">
<!-- passenger detail goes here. You will find the code in includes/passenger_Detail.php -->
</div>
</div>
<!-- end PHP while loop -->
I have left the examples I have tried to get TinyMCE to work. I have a sneaky suspicion bad coding practice is the culprit. Each of the textareas have an ID of #notes which I think is the cause. But looking at documentation I don't think tinyMCE lets you use classes to target textareas. Unless I have to loop through all textareas. I'm just spitballing here.
Please inform me if more info is required. Thanks again.

I ended up solving the issue but using a unique ID for each of the textarea elements. So instead of each textarea having the ID "notes", it is now "notes_unique customer_ID".
Following is my answer:
j$.ajax({
type: "POST",
url: "/include/passenger_Detail.php",
data: { customer_ID_Data : customer_ID },
success: function(data) {
//console.log("Returned data: "+data);
//get returned data and add into appropriate place
insert_Data.html(data);
notes = insert_Data.find('textarea').attr('id');
var oldEditor = tinyMCE.get('notes_'+customer_ID);
if (oldEditor != undefined) {
tinymce.remove(oldEditor);
}
tinyMCE.execCommand('mceAddControl', false, 'notes_'+customer_ID);
}
});
