How can I pass the values of the relevant row into the modal when a click event occurs on a table?

When a click event occurs on a table, I want to pass the values of the relevant row into the modal. I wrote a code like this, but the values of the top row are always passed into the modal. What I want to do is to show the values in the row I clicked in the modal. How can I provide this?
my table codes here:
<table class="table align-middle" id="customerTable">
<thead class="table-light">
<tr>
<th class="sort" data-sort="name">Name Surname</th>
<th class="sort" data-sort="company_name">Phone Number</th>
<th class="sort" data-sort="leads_score">Note</th>
<th class="sort" data-sort="phone">Status</th>
<th class="sort" data-sort="location">Personal Name</th>
<th class="sort" data-sort="tags">Data Name</th>
<th class="sort" data-sort="action">Edit</th>
</tr>
</thead>
<tbody class="list form-check-all">
{% for x in model %}
<tr>
<td class="table-namesurname">{{x.name}}</td>
<td class="table-phonenumber">{{x.phonenumber}}</td>
<td class="table-note">{{x.note}}</td>
<td class="table-status">{{x.status}}</td>
<td class="table-callname">{{x.callname}}</td>
<td class="table-dataname">{{x.dataname}}</td>
<td>
<ul class="list-inline hstack gap-2 mb-0">

<a class="edit-item-btn" id="call-button" href="#showModal" data-bs-toggle="modal" data-id="{{x.id}}"><i class="ri-phone-line fs-16"></i></a> <!-- Here is the edit button -->

{% endfor %}

The problem here is that the values of the clicked element in the table are not coming. Whichever I click, the values of the element at the top of the table are displayed. How can I solve this problem?

HTML id attribute should be unique, adding multiple elements with the same id, when you select, you will only get the first element that has this id, you need to select the rows by class, you have edit-item-btn class for the button.
<script type="text/javascript">
$(document).ready(function () {
$(".edit-item-btn").click(function() {
var nameSurname = $(this).closest('tr').find('.table-namesurname').text();
var phoneNumber = $(this).closest('tr').find('.table-phonenumber').text();
var note = $(this).closest('tr').find('.table-note').text();
var status = $(this).closest('tr').find('.table-status').text();
var callName = $(this).closest('tr').find('.table-callname').text();
var dataName = $(this).closest('tr').find('.table-dataname').text();
$("#call-name-surname").val(nameSurname)
$("#call-phone-number").val(phoneNumber)
$("#call-note-field").val(note)
$("#call-status-field").val(status)
$("call-persnoel-name").val(callName)
});
});

How to update values for each columns of row from modal?

I have an HTML code like this:
<body>
<div class="container">
<div style="margin-top: 50px;">
<table class="table table-hover" style="width: 100%;">
<tbody>
<tr>
<th>0</th>
<td class="cTenSanPham">Samsung Galaxy Note 8</td>
<td class="cGiaSanPham">23.000.000 VND</td>
<td>
<button type="button" class="btn btn-primary edit" data-toggle="modal" data-target="#exampleModal" onclick="editProductModal()">Chỉnh sửa</button>
<button type="button" class="btn btn-danger delete-row-tb">Xóa</button>
</td>
</tr>
</tbody>
</table>
</div>
</div>
In modal code
<div class="modal-body">
<form>
<div class="form-group">
<label>
<h5 class="">Mã sản phẩm</h5>
</label>
<input type="text" class="form-control" id="iMaSanPham" name="nMaSanPham" readonly>
</div>
<div class="form-group">
<label>
<h5 class="">Tên sản phẩm</h5>
</label>
<input type="text" class="form-control" id="iTenSanPham" name="nTenSanPham">
</div>
<div class="form-group">
<label>
<h5 class="">Giá sản phẩm</h5>
</label>
<input type="number" min="500" max="999999999" class="form-control" id="iGiaSanPham"
name="nGiaSanPham">
</div>
</form>
</div>
And an Javascript code like this:
function editProductModal() {
$(document).on("click", ".edit", function () {
$(this).parents("tr").find("th").each(function () {
document.getElementById("iMaSanPham").value = $(this).text();
});
$(this).parents("tr").find(".cTenSanPham").each(function () {
document.getElementById("iTenSanPham").value = $(this).text();
});
$(this).parents("tr").find(".cGiaSanPham").each(function () {
document.getElementById("iGiaSanPham").value = parseInt($(this).text().replace(/\D/g, ''));
});
});
}
I want when I click the button 'Chỉnh sửa' on any row, a modal will open and fill data from this row into this modal (the modal of bootstrap 4). I can edit on this modal, then I press a button to pass updated data to table. How to do it in function editProductModal() in file JS. Thank you so much

var $currentEditRow;
$(document).on("click", ".edit", function() {
$currentEditRow = $(this).parents("tr");
editProductModal($(this).parents("tr"));
});
function editProductModal(row) {
document.getElementById("iMaSanPham").value = $(row).find("th").text();
document.getElementById("iTenSanPham").value = $(row).find(".cTenSanPham").text();
document.getElementById("iGiaSanPham").value = parseInt($(row).find(".cGiaSanPham").text().replace(/\D/g, ''));
}
function update() {
$currentEditRow.find("th").text(document.getElementById("iMaSanPham").value);
$currentEditRow.find(".cTenSanPham").text(document.getElementById("iTenSanPham").value);
$currentEditRow.find(".cGiaSanPham").text(document.getElementById("iGiaSanPham").value);
$('#exampleModal').modal('hide');

When editing the current tr row, store the dom of the current row, so you can determine which line to update to in the modal.
You can try to update the row data in my code snippet.

You are improperly mixing inline onclick and jQuery click event listeners together.
Remove the function and the onclick and just use the jQuery code inside the function by itself to manage the event
You also don't need an each loop to access the elements within the row.
Simplified version:
$(document).on("click", ".edit", function() {
var $row = $(this).closest('tr'),
thText = $row.find('th').text(),
cTenSanPham = $row.find('.cTenSanPham').text(),
cGiaSanPham = $('.cGiaSanPham').text().replace(/\D/g, '');
$('#iMaSanPham').val(thText);
$('#iTenSanPham').val(cTenSanPham);
$('#iGiaSanPham').val(cGiaSanPham);
});

Laravel: javascript for some reasons is not working

I have to develop a CRUD function to manage a DB. The button EDIT and DELETE open modal window and interact with the DB. What I cannot get is that the script works perfectly for EDIT but seems to be ignored for DELETE...what is wrong?
Those are my routes:
Route::get('/', 'DataController#overview');
Route::get('/myproject', 'ProjectsController#getForm');
Route::post('/myproject/create', 'ProjectsController#create');
Route::post('/myproject/update', 'ProjectsController#update');
Route::post('/myproject/delete', 'ProjectsController#delete');
Route::get('/upload','DataController#showform');
Route::post('/upload', 'DataController#read_xsl');
Route::get('/jobcontents', 'DataController#showscrape');
Route::post('/jobcontents', 'DataController#scrape');
This is my controller:
public function update(Request $request)
{
#$projectID = \DB::table('projects')->select('id')->get(),
try
{
//Find the project id in Project_model
#var_dump($request->toArray());
#var_dump($request->get('id'));
#exit;
$project = Project_model::findOrFail($request->get('id'));
//Set project object attributes
$project->name = $request->get('name');
$project->description = $request->get('description');
// Save/update project.
$project->save();
#return view('form_project')->with('project', $project);
return redirect()->back()->with('project', $project);
#return back();
}
catch(ModelNotFoundException $err)
{
return redirect()->action('ProjectsController#getForm');
}
}
public function delete(Request $request)
{
try
{
var_dump($request->toArray());
exit;
$project = Project_model::findOrFail($request->get('id'));
$project->delete();
return redirect()->back()->with('project', $project);
}
catch(ModelNotFoundException $err)
{
return redirect()->action('ProjectsController#getForm');
}
}
This is my blade:
//search and retrieve data from Modal
$(document).ready(function() {
$('#editModal').on('show.bs.modal', function(event) {
var button = $(event.relatedTarget)
var name = button.data('myname')
var description = button.data('mydesc')
var project_id = button.data('projectid')
var modal = $(this)
//put the values in modal <input>
modal.find('.modal-body #name').val(name);
modal.find('.modal-body #description').val(description);
modal.find('.modal-body #project_id').val(project_id);
})
$('#deleteModal').on('show.bs.modal', function(event) {
var button = $(event.relatedTarget)
var projctid = button.data('projid')
var modal = $(this)
modal.find('.modal-body #projid').val(projctid);
})
});

The problem was just related to Chrome CACHE REFRESH!!!
So be sure to clear cache (Shift+F5) and not only refresh the page when something does not work!

document.getElementById() on a value that is set through a Meteor template

So I've been trying to build a website using Meteor and am quite new with it. I am trying to have javascript that will make use of the values on the page and then create a download from those values. These values differ depending on which page the user is on as the meteor template is loaded with specific information. The way I would think is would work is:
var thing = document.getElementById("tcpout").value;
but when I test this I get "undefined". Now if I don't do .value then do something like
console.log(document.getElementById("tcpout"));
the output in the console is this:
<td id="tcpout"> 50443</td>
where 50443 is the value that I want. Yet I can't seem to figure out how to get that into the javascript. I am using meteor and have tried a few things through meteor's project .js file, but can't seem to figure out how to incorporate dynamic fields into javascript. Essentially I just want to figure out the easiest and best way to work with the mongodb data on the client-side with javascript. Here is the template and the meteor js file.

to change the value of input you need to use val() :
<script type="text/javascript">
$(document).ready(function () {
$('.update').on('click', function () {
var $this = $(this);
var idProduct = $this.data('id');
var nameProduct = $this.data('name');
var costProduct = $this.data('cost')
var profitProduct = $this.data('profit')
$('#nameProduct').val(nameProduct);
$('#costProduct').val(costProduct);
$('#profitProduct').val(profitProduct);
$("#updateModal #form_update #idProduct").val(idProduct);
$('#updateModal').modal();
});
});

Your modal contains only inputs.
For setting the value of input you used $('#nameProduct').text(nameProduct) and that's the wrong thing. You need the val() method.
$('#nameProduct').val(nameProduct);
.text() method is used specially for div, span, etc.
UPDATE
<td>#Html.DisplayFor(model => sale.idProduct)</td> generates a span with the follow properties: id and name have value idProduct. The problem is that you have two elements with same id(in table and in modal). id attribute must be unique in DOM.
Modal
<div id="updateModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dissmiss="modal">×</button>

JAVASCRIPT
<script type="text/javascript">
$(document).ready(function () {
$('.update').on('click', function () {
var modal=$('#updateModal');
var idInput = modal.find('input.modalInput').eq(0);
var nameInput = modal.find('input.modalInput').eq(1);
var costInput = modal.find('input.modalInput').eq(2);
var profitInput = modal.find('input.modalInput').eq(3);
idInput.val($(this).data('id'));
nameInput .val($(this).data('name'));
costInput.val($(this).data('cost'));
profitInput .val($(this).data('profit'));
modal.modal();
});
});
</script>
HTML
foreach(var sale in Model)
{
<tr>
<td>#Html.DisplayFor(model => sale.idProduct)</td>
<td>#Html.DisplayFor(model => sale.nameProduct)</td>
<td>#Html.DisplayFor(model => sale.costProduct)</td>
<td>#Html.DisplayFor(model => sale.profitProduct)</td>
<!--Get values to put on Modal-->
<td><a class="update" data-id="#sale.idProduct" data-name="#sale.nameProduct" data-cost="#sale.costProduct" data-profit="#sale.profitProduct"><span class="glyphicon glyphicon-edit">Alterar</span></a></td>
</tr>
}

you must use val().You use like a text("asda").you change these problem resolve
