jQuery validation on dynamic table form not working on using blur

I am creating form dynamically which has n rows (coming from array having n elements). Form fields have two type of columns (text & number) which I have given different id.
Although JQuery validation is working but "validate parts button" is not responding correctly. From the code condition it should not be enabled in case text is not valid.
Thanks..!

$(...).cells is undefined in jQuery

i have two forms, form1 contains the date and the display button, the show button allows you to hide the form1 and display the form2, the form2 contains the chosen date and a datatable with checkboxes and button valider, i want when i click the show button console show matricules of salaries.
$(document).ready(function() {
$('#check_all').on('click', function(e) {
if ($(this).is(':checked', true)) {
$(".checkbox").prop('checked', true);
} else {
$(".checkbox").prop('checked', false);
}
});
$('.checkbox').on('click', function() {
if ($('.checkbox:checked').length == $('.checkbox').length) {
$('#check_all').prop('checked', true);
} else {
$('#check_all').prop('checked', false);
}
});
$("#form2").hide();
$("#hide").click(function() {
$("#form1").hide();
$("#form2").show();
let dat = $("#dateS").val();
$("#da").text(dat);
$("tr").each(function(i, r) {
let mat = $(r).cells[2].innerText;
console.log(mat);

Instead of $(r).cells[2].innerText use jQuery
$(r).find('td').eq(2).text()
or:
$(this).find('td:eq(2)').text();
cells is used in vanilla JavaScript to get the cells from TableRowElement, while your $(r) is a reference to a collection of elements wrapped into a jQuery object
therefore if you want to use JavaScript you still can, but like:
r.cells[2].textContent
also, notice the use of the preferred textContent vs innerText

best approach in adding a comma to a number like 123,456.78 in jquery

found this solution in this solution
function commaSeparateNumber(val){
while (/(\d+)(\d{3})/.test(val.toString())){
val = val.toString().replace(/(\d+)(\d{3})/, '$1'+','+'$2');
}
return val;
}
in this link add commas to a number in jQuery
I am trying to apply it in my project. it works in one column but it doesn't work in price and sub total
function commaSeparateNumber(val){
while (/(\d+)(\d{3})/.test(val.toString())){
val = val.toString().replace(/(\d+)(\d{3})/, '$1'+','+'$2');
}
return val;
}

Thank you so much in advance!

The problem is that parseFloat fails to correctly parse the value from the total cost textbox because it contains one or more ,. You need to remove the , from the string before parsing to float. You can remove any ,'s by calling .replace(/,/g,'') on the textbox value in the calculateSubTotal function.
It seems that for some values the function commaSeparateNumber doesn't work as expected. I removed it from the snippet below and replaced it with toLocaleString() which takes parameters for locale and minimum/maximum fraction digits .toLocalString("en-US", { maximumFractionDigits: 2}). Set the locale to one you know uses , to separate thousands. If you know that won't be an issue you can pass undefined for the locale.
Your snippet has been updated below:
var rowCount = 1;
$('#add').click(function() {
rowCount++;
$('#orders').append('<tr id="row'+rowCount+'"><td><input class="form-control product_price" type="number" data-type="product_price" id="product_price_'+rowCount+'" name="product_price[]" for="'+rowCount+'"/></td><input class="form-control" type="hidden" data-type="product_id" id="product_id_'+rowCount+'" name="product_id[]" for="'+rowCount+'"/><td><input class="form-control quantity" type="number" class="quantity" id="quantity_'+rowCount+'" name="quantity[]" for="'+rowCount+'"/> </td><td><input class="form-control total_cost" type="text" id="total_cost_'+rowCount+'" name="total_cost[]" for="'+rowCount+'" readonly/> </td><td><button type="button" name="remove" id="'+rowCount+'" class="btn btn-danger btn_remove cicle">-</button></td></tr>');
});
// Add a generic event listener for any change on quantity or price classed inputs
$("#orders").on('input', 'input.quantity,input.product_price', function() {
getTotalCost($(this).attr("for"));
});
$(document).on('click', '.btn_remove', function() {
var button_id = $(this).attr('id');
$('#row'+button_id+'').remove();
});
// Using a new index rather than your global variable i
function getTotalCost(ind) {
var qty = $('#quantity_'+ind).val();
var price = $('#product_price_'+ind).val();
var totNumber = (qty * price);
// .toLocaleString
var tot = totNumber.toLocaleString("en-US", { maximumFractionDigits: 2});
$('#total_cost_'+ind).val(tot);
calculateSubTotal();
}
function calculateSubTotal() {
var subtotal = 0;
$('.total_cost').each(function() {
// replace ',' here
subtotal += parseFloat($(this).val().replace(/,/g,''));
});
// toLocaleString
$('#subtotal').val(subtotal.toLocaleString("en-US", { maximumFractionDigits: 2}));

How to select a table row data and send it to a Edit Modal for update data using jQuery, JavaScript and AJAX?

I have a dynamic table, which contains some data.In my table there is a option called Edit,by clicking the edit option a SideNav is opening.I want to fetch that particular row from the table and want to place those information into my sideNav.
My HTML and JS file is below.
/index.html
<table class="table-bordered mytable">
<thead class="table-head">
<tr>
<th>Name</th>
<th>Email</th>
<th>Status</th>
<th>Address</th>
<th>Action</th>

</div>
<div class="form-group">

</div>

$(function(){
$.get("/api/dashboard/v1", function (response) {
// console.log(response);
var myhtmlsec= "";
for(var i=0; i<response.data.length; i++) {
myhtmlsec += "<tr>";
myhtmlsec +="<td>"+response.data[i].user_name+"</td>";
myhtmlsec +="<td>"+response.data[i].email+"</td>";
myhtmlsec +="<td></td>";

});
});
function myEdit(a) {

var tdEmail = par.children("td:nth-child(2)");
var tdAddress = par.children("td:nth-child(3)");
//want to edit/update userinformation through this "api/updateUser/v1:id" using put method
}
function myDelete() {
alert();
};

using jquery
function myEdit(elem)
{
$('#user_name').val($(elem).parent().parent().find('td:nth-child(1)').html());
...
/* fill other fields */
}

Here is perfect and clean solution:
$('tbody tr').click(
function(){
var name = $(this).find("td:nth-child(1)").html();
var email = $(this).find("td:nth-child(2)").html();
var addr = $(this).find("td:nth-child(3)").html();
$('#user_name').val(name);
$('#email_id').val(email);
$('#address').val(addr);
});

It's happening because you don't have ng-model set for the 3rd input box,
you could write a function to calculate the sum and assign the value to the $scope variable.
Demo
var app = angular.module("myapp", [])
app.controller("ListController", ['$scope', function($scope) {
$scope.personalDetails = [{
'num1': '',
'num2': '',
'add': ''
}];
$scope.calculateSum = function(val) {
val.add = parseFloat(val.num1) + parseFloat(val.num2);
}
$scope.addNew = function(personalDetail) {
$scope.personalDetails.push({
'num1': "",
'num2': "",
'add': ""
});
};
$scope.parseFloat = function(value) {
return parseFloat(value);
}
}]);
