How can I correctly count rows in multirow form script?

I have problem with multirow form script modified by me. I added function who is filling ean, product_description and category_id inputs by values from ProductsData json array on the basis of manufacturer_catalog_nr value. Everything is OK when I'm adding rows singly and at once I fill manucaturer_catalog_nr. Script is filling rest of inputs. But when I add two or more rows script is filling only last ean, product_description and category_id inputs. The same problem is when remove row and add next one.
I know only that the problem is in counting but I don't have idea how can I fix this.
$(document).ready(function(){
var count = 0;
$('#add').click(function(){
count = document.getElementById("product_table_rows").rows.length;
var html_code = '';
var html_code = "<tr id='row"+(count+1)+"'>";
html_code += '<td><div class="input-group"><div class="input-group-addon">P</div><input list="manufacturer_catalog_nr_list" autocomplete="off" type="text" id="manufacturer_catalog_nr_'+count+'" name="manufacturer_catalog_nr['+count+']" class="form-control catalog-filter" title="Numer katalogowy producenta. Jeśli go nie znasz, wpisz numer dystrybutora." required /></div><div class="input-group"><div class="input-group-addon">D</div><input type="text" id="supplier_catalog_nr_'+count+'" name="supplier_catalog_nr['+count+']" class="form-control catalog-filter" title="Numer katalogowy dystrybutora. Jeśli go nie znasz wpisz numer producenta." required /></div>';
html_code += '<td><input type="text" id="ean_'+count+'" name="ean['+count+']" pattern="[0]|.{8,8}|.{13,13}" required title="Wpisz 8 lub 13 cyfr numeru EAN lub 0 jeżeli go nieznasz" class="form-control ean-filter" /></td>';
html_code += '<td><input type="text" id="quantity_'+count+'" name="quantity['+count+']" class="form-control qty-filter" required/></td>';
html_code += '<td><select id="unit_'+count+'" name="unit['+count+']" class="form-control"><option value="szt.">szt.</option><option value="m">m</option><option value="kg">kg</option><option value="kpl.">kpl.</option></select></td>';
html_code += '<td><textarea rows="2" cols="50" style="width:100%; height:66px; resize: vertical; min-height:34px;" id="product_description_'+count+'" name="product_description['+count+']" class="form-control" /></textarea></td>';
html_code += '<td><div class="input-group"><input type="text" id="price_'+count+'" name="price['+count+']" class="form-control price-filter"/><div class="input-group-addon">zł</div></div></td>';
html_code += '<td><select id="category_id_'+count+'" name="category_id" class="form-control" required></select><select onchange="this.className=this.options[this.selectedIndex].className" id="" name="" value="" class="form-control green"><option class="form-control green" selected>Normalny</option><option class="form-control red">Wysoki</option></select></td></td>';
html_code += '<td><textarea rows="1" cols="50" style="width:100%; height:66px; resize: vertical; min-height:34px;" id="assembly_'+count+'" name="assembly['+count+']" class="form-control" /></textarea></td>';
html_code += "<td><button type='button' name='remove' data-row='row"+(count+1)+"' class='btn btn-danger btn-xs remove'><span class='glyphicon glyphicon-minus'></span></button></td>";
html_code += "</tr>";
$.getJSON('../manage_categories.php', function(data) {
var html = "";
html += '<option hidden selected disabled>Wybierz kategorię</option>';
for(var option in data){
html += `<optgroup label="`+ option +`">`;
data[option].forEach(function(item){
html += `<option value="` + item["pc_option_value"] + `" >`+ item["pc_option_name"] +`</option>`
});
html += `</optgroup>`;
}
$('#category_id_'+count).append(html);
});
$('#product_table').append(html_code);
$('#manufacturer_catalog_nr_'+count).change(function () {
var input_catalog_nr = $(this).val();
var check = false;
for (var index = 0; index < ProductsData.length; ++index) {
var product = ProductsData[index];
if(product.manufacturer_catalog_nr == input_catalog_nr){
check = true;
break;
}
}
if(check == true) {
$('#ean_'+count).val(ProductsData[index].ean);
$('#product_description_'+count).val(ProductsData[index].product_description);
$('#category_id_'+count).val(ProductsData[index].category_id);
}
});
$.getScript("js/input_filters.js",function(){
Inputs_filters();
});
});
$(document).on('click', '.remove', function(){
var delete_row = $(this).data("row");
$('#' + delete_row).remove();
});
});

I found the solution:
Add an attribute data-line='+count+' in manufacturer_catalog_nr input,
Set var "input_line" with data-line value in input filling function,
var input_line = $(this).data("line");`
Add var input_line to input to be filled,
$('#ean_'+input_line).val(ProductsData[index].ean);
$('#product_description_'+input_line).val(ProductsData[index].product_description);
$('#category_id_'+input_line).val(ProductsData[index].category_id);
Enjoy.

dynamically add input field value jQuery

html code we can get the value
<input type="text" name="value1[]" id="value1"/>
<input type="mail" name="value2[]" id="value2"/>
<input type="text" name="total[]" id="total" />
i can try with this in jQuery i can get only html value result, after add new row i can't get the value
$(document).ready(function () {
var counter = 0;
$("#addrow").on("click", function () {
var newRow = $("<tr>");
var cols = "";
cols += '<td>Item1</td>';
cols += '<td><input type="text" class="form-control" name="value1[]" id="value2' + counter + '"></td>';
cols += '<td><input type="text" class="form-control" name="foreign_milion[]" id="foreign_milion_' + counter + '"></td>';
cols += '<td><input type="text" readonly class="form-control" name="total_milion[]" id="total_"' + counter + '"></td>';
cols += '<td><input type="button" class="ibtnDel btn btn-md btn-danger " value="Delete"></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
counter++;
});
$("#value2").keyup(function () {
var value1 = $("#value1").val();
var value2 = $("#value2").val();
var totalincome = parseInt(value1) + parseInt(value2);
//alert(totalincome);
$("#total").val(totalincome);
})
});

First of all the id must be unique in the same document, else you'll end up with incorrect HTML code, so you need to replace the ids with common classes instead in your code as a first step.
Then you need to use event delegation to attach the event to your inputs since the must of them are created dynamically with the JS code.
I prefer the use of input event instead of keyup when you track the user inputs, so the event will be something like:
$(document).ready(function() {
var counter = 1;
$("body").on("input", ".calculated_value", function() {
var parent_row = $(this).closest('tr');
var totalincome = 0;
parent_row.find('.calculated_value').each(function() {
totalincome += parseInt($(this).val() || 0);
});
parent_row.find(".total").val(totalincome);
});
$("#addrow").on("click", function() {
var newRow = $("<tr>");
var cols = "";
cols += '<td>Item ' + counter + '</td>';
cols += '<td><input type="text" class="form-control calculated_value" name="value1[]"></td>';
cols += '<td><input type="text" class="form-control calculated_value" name="foreign_milion[]"></td>';
cols += '<td><input type="text" class="form-control total" name="total_milion[]" readonly></td>';
cols += '<td><input type="button" class="ibtnDel btn btn-md btn-danger " value="Delete"></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
counter++;
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table class="order-list">
<tr>
<td>Item </td>
<td><input type="text" class="form-control calculated_value" name="value1[]"></td>
<td><input type="text" class="form-control calculated_value" name="foreign_milion[]"></td>
<td><input type="text" class="form-control total" name="total_milion[]" readonly></td>
</tr>
</table>
<button id="addrow">Add row</button>

I have tried this one, may be this is what you are looking into.
please take a look at the snippet.
jQuery(document).ready(function () {
var count = 1;
jQuery('#add').on('click', function(){
var el = `<section id="inpFields">
<input type="text" name="value1[]" id="value`+count+`" placeholder="value `+count+`"/>
<input type="text" name="value2[]" id="value2`+count+`" placeholder="value `+count+`"/>
<input type="text" name="total[]" id="total`+count+`" placeholder="total" />
<button class="totalBtn" data-id="`+count+`">Total</button>
</section>`;
jQuery('#inpFields').append(el);
count++;
});
jQuery('#add').click();
jQuery(document).on('click', '.totalBtn', function(){
var i = this.dataset.id;
var value1 = jQuery('#value'+i).val();
var value2 = jQuery('#value2'+i).val();
var totalincome = parseInt(value1) + parseInt(value2);
//alert(totalincome);
jQuery('#total'+i).val(totalincome);
})
});

i have add dynamic row using jquery now i want to add those column

i have add dynamic row using jquery now i want to add those column of the row. Down below is my code i am not able to add the column that is created dynamically.the first textbox is calculated and answer is displayed in grandtotal textbox but the rest textbox cannot be calculated.
<tbody>
<tr class="data-contact-person">
<td>
<input type="text" name="a" class="form-control a" />
</td>
<td>
<input type="text" name="b" class="form-control b" />
</td>
<td>
<input type="text" name="c" class="form-control c" />
</td>
<td>
<input type="text" name="d" class="form-control d" />
</td>
<td>
<button type="button" id="btnAdd" class="btn btn-xs btn-primary classAdd">Add More</button>
</td>
</tr>
</tbody>
<tfoot>
<tr>
<td></td>
<td>Grand-Total</td>
<td>
<input data-val="true" id="grdtol1" name="grdtol1" value="" class="form-control text-box single-line" type="text">
</td>
<td>
<input data-val="true" id="grdtol" name="grdtol2" value="" class="form-control text-box single-line" type="text">
</tr>
</tfoot>
$(document).ready(function () {
$(document).on("click", ".classAdd", function () { //
var rowCount = $('.data-contact-person').length + 1;
var contactdiv = '<tr class="data-contact-person">' +'<td><input type="text" name="a' + rowCount + '" class="form-control a" /></td>' +
'<td><input type="text" name="b' + rowCount + '" class="form-control b" /></td>' +
'<td><input type="text" name="c' + rowCount + '" class="form-control c" /></td>' +
'<td><input type="text" name="d' + rowCount + '" class="form-control d" /></td>' +
'<td><button type="button" id="btnAdd" class="btn btn-xs btn-primary classAdd">Add More</button>' +
'<button type="button" id="btnDelete" class="deleteContact btn btn btn-danger btn-xs">Remove</button></td>' +
'</tr>';
$('#maintable').append(contactdiv); // Adding these controls to Main table class
});
});
$(document).on("click", ".deleteContact", function () {
$(this).closest("tr").remove(); // closest used to remove the respective 'tr' in which I have my controls
});
$(document).ready(function (e) {
$("input").change(function () {
var grdtol1 = 0;
$("input[name=c]").each(function () {
grdtol1 = grdtol1 +parseInt( $(this).val());
})
$("input[name=grdtol1]").val(grdtol1);
});
})

First, a piece of advice, don't create multiple $(document).ready() functions in the same javascript file, you just need one.
You haven't post your html code, so I'm guessing here, but I suppose you initially have row with the inputs and you also have an input with name="grdtol1" where you want to calculate the sum of the values of the column, and it has to refresh when you change the value in any of the inputs.
According to that, I see this problems...
You need to use event delegation for the input onchange event (like you do for the .deleteContact button). You're associating the event directly, so it only applies to the elements that are in the DOM when the page loads, and not for the rows you add dinamically. You can associate the event to the table and delegate it to the input, for example.
Inside of the event, you're selecting $("input[name=c]"), but according to the previous code, your inputs will have name="c' + rowCount + '". You chould use the class to select them.
If you delete one row, you should also recalculate the sum, because the input of that row will disappear.
Putting all together...
$(document).ready(function () {
$(document).on("click",".classAdd",function() {
var rowCount = $('.data-contact-person').length + 1;
var contactdiv = '<tr class="data-contact-person">' +'<td><input type="text" name="a' + rowCount + '" class="form-control a" /></td>' +
'<td><input type="text" name="b' + rowCount + '" class="form-control b" /></td>' +
'<td><input type="text" name="c' + rowCount + '" class="form-control c" /></td>' +
'<td><input type="text" name="d' + rowCount + '" class="form-control d" /></td>' +
'<td><button type="button" id="btnAdd" class="btn btn-xs btn-primary classAdd">Add More</button>' +
'<button type="button" id="btnDelete" class="deleteContact btn btn btn-danger btn-xs">Remove</button></td>' +
'</tr>';
$('#maintable').append(contactdiv); // Adding these controls to Main table class
});
function calculateGrandtotal() {
var grdtol1 = 0;
$('input.c').each(function() {
grdtol1 += parseInt($(this).val());
})
$("input[name=grdtol1]").val(grdtol1);
}
$('#maintable').on('click','.deleteContact',function () {
$(this).closest('tr').remove();
calculateGrandtotal()
})
.on('change','input.c',function() {
calculateGrandtotal()
});
});
I hope it helps

How to use loop inside append in jQuery function

i would like to append a new html code, buy clicking a button. however in the append there are a looping to show the html code.
<script>
var day_left = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
$(".add_schedule").click(function () {
if ($('.day-part').is(':empty')){
alert("You have limit schedule time!")
}else{
var stack = $(this).parent().find('#stack').val();
alert("form-schedule-"+stack);
$(this).before('<div class="form-schedule" id="form-schedule-'+stack+'">' +
'<div class="col-md-4">' +
'<label>Start Time</label><input type="time" placeholder="ex : 00:00" name="time['+stack+'][open_time]" class="open_time form-control" id="open_time'+stack+'">' +
'</div>' +
'<div class="col-md-4">' +
'<label>End Time</label><input type="time" placeholder="ex : 21:00" name="time['+stack+'][close_time]" class="close_time form-control" id="close_time"></div>' +
'<div class="col-md-4">' +
'<label>Pilih Hari</label> ' +
'<div class="dropdown dropdown-payment">' +
'<button class="btn btn-primary btn-sm dropdown-toggle" type="button" data-toggle="dropdown">Select Date <span class="caret"></span></button> ' +
'<div class="dropdown-menu"><div class="everyday-part">' +
'<li> <label> ' +
'<input type="checkbox" id="everyday" class="everyday_check_box form form-control" name="time['+stack+'][everyday]" value="7"> Everyday </label>' +
'</li>' +
'</div>' +
'<div class="day-part">'+
// The Problem is Started From Here
$.each(day_left,function (i,val) {
$('<li><label><input type="checkbox" checked="checked" id="date_check_box" class="form form-control" name="time[' + stack + '][date][]" value="' + i + '">'+val+'</label> </li>');
})+'</div> </div> </div> </div></div><div class="clearfix"></div><br> ');
// End Of the Problem
stack = parseInt(stack)+1;
$(this).parent().find('#stack').val(stack);
}
});
</script>
actually i could append the html. But there is a bug in my $.each(day_left,function(i,val)){});
its only return the value of day_left which they are like sunday,monday,.... The code doesn't show the html code
My expected is it would be returned like this
but my code is only return :

Please make a function like this
function makeString(day_left,stack){
var str = '';
for(var i = 0; i <= day_left.length ; i++ ){
str += '<li><label><input type="checkbox" checked="checked" id="date_check_box" class="form form-control" name="time[' + stack + '][date][]" value="' + i + '">'+day_left[i]+'</label> </li>';
}
return str;
}
and change as following
$(this).before('<div class="form-schedule" id="form-schedule-'+stack+'">' +
'<div class="col-md-4">' +
'<label>Start Time</label><input type="time" placeholder="ex : 00:00" name="time['+stack+'][open_time]" class="open_time form-control" id="open_time'+stack+'">' +
'</div>' +
'<div class="col-md-4">' +
'<label>End Time</label><input type="time" placeholder="ex : 21:00" name="time['+stack+'][close_time]" class="close_time form-control" id="close_time"></div>' +
'<div class="col-md-4">' +
'<label>Pilih Hari</label> ' +
'<div class="dropdown dropdown-payment">' +
'<button class="btn btn-primary btn-sm dropdown-toggle" type="button" data-toggle="dropdown">Select Date <span class="caret"></span></button> ' +
'<div class="dropdown-menu"><div class="everyday-part">' +
'<li> <label> ' +
'<input type="checkbox" id="everyday" class="everyday_check_box form form-control" name="time['+stack+'][everyday]" value="7"> Everyday </label>' +
'</li>' +
'</div>' +
'<div class="day-part">'+
// The Problem is Started From Here
makeString(day_left,stack)+'</div> </div> </div> </div></div><div class="clearfix"></div><br> ');
plnkr https://plnkr.co/edit/aBLj49Yv2g4EakeKjlqI?p=preview

you can do like that......
just use return function or make you iteration returnable.
<script>
var day_left = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
$(".add_schedule").click(function () {
if ($('.day-part').is(':empty')){
alert("You have limit schedule time!")
}else{
var stack = $(this).parent().find('#stack').val();
alert("form-schedule-"+stack);
$(this).before('<div class="form-schedule" id="form-schedule-'+stack+'">' +
'<div class="col-md-4">' +
'<label>Start Time</label><input type="time" placeholder="ex : 00:00" name="time['+stack+'][open_time]" class="open_time form-control" id="open_time'+stack+'">' +
'</div>' +
'<div class="col-md-4">' +

'<div class="day-part">'+
// The Problem is Solved
function(){var s='';
$.each(day_left,function (i,val) {
s += '<li><label><input type="checkbox" checked="checked" id="date_check_box" class="form form-control" name="time[' + stack + '][date][]" value="' + i + '">'+val+'</label> </li>';

return s;}

How to get the checkbox valu from below code

newTextBoxDiv.html(
'<td border="2">'+number+'</td>'+
'<td>'+grouptext+'</td>'+
'<td style="display:none">'+groupVal+'</td>'+
'<td>'+itemText+'</td>'+
'<td style="display:none">'+itemId+'</td>'+
'<td>'+cuttingText+'</td>'+
'<td style="display:none">'+cuttingId+'</td>'+
'<td>
<input type="text" class="ui-state-default ui-corner-all"
name="textbox' + counter + '" id="textbox' + counter + '" value="" size="13" />
</td>'+
'<td> <input type="checkbox" name="samples"/> </td>'+
'<td>
<input type="text" class="ui-state-default ui-corner-all" size="8"
name="textbox' + counter +'" id="textbox1' + counter + '" value="" size="13" />
</td>'
);
newTextBoxDiv.appendTo("#example");
Now how can i get the check box true false values please help me

after the edit by #Daff it seems like you can use the below code...
$("#example").on("click",function(){
var val = $(this).find(":checkbox[name='samples']").val();
});

Later within the same block of code:
var isChecked = newTextBoxDiv.find('input[name="samples"]').is(':checked');
Or, in another context:
var isChecked = jQuery('#example').find('input[name="samples"]').is(':checked');

Make use of .is(':checked') it returns boolean
$('input[type="checkbox"][name="samples"]').click(function(){
alert($(this).is(':checked'));
});
fiddle : http://jsfiddle.net/2jZM2/1/

Try this...
$(':checkbox',newTextBoxDiv).each(function(){
alert($(this).attr('checked'));
})
