Get all values per table column dynamically using javascript or jquery

I need to get all values per column dynamically and save it using JS or Jquery. I have a photo here so that you guys can visualize what I am trying to do. Please see the image.
Sad to say this is as far as I can go. I cant seems to get what I realy want to achieve. Just a beginner here.
$(function() {

);
$('#supplier_table > thead > tr#second-header').append(
'<th>Price</th>' +
'<th>Total</th>'
);

javascript function in dynamically input

I'm having an issue using jQuery function multiplication (math) with dynamically created inputs (again created with jQuery). I can't get my function to bind to the new inputs. for the first row its work, but for second row it did not work (second row and more using dynamically input).
Here my html code
<table class="table table-condensed" style="margin-left: 10px;">
<thead>
<tr>
<th width="100px">Nama</th>
<th width="100px">Kode</th>
<th width="100px">Harga</th>
<th width="100px">Jumlah</th>
<th width="100px">Total</th>
<th width="80px"></th>
</tr>
</thead>
<tbody id='itemlist' >
<tr>
<td><input id='nama' name='nama_input[]' class='form-control' /></td>
<td><input id='kode' readonly name='kode_input[]' class='form-control' /></td>
<td><input id='harga' name='harga_input[]' class='form-control' onkeyup="sum();" /></td>
<td><input id='jumlah' autocomplete="off" name='jumlah_input[]' class='form-control' onkeyup="sum();" /></td>
<td><input id='total' name='total_input[]' class='form-control' value=" " /></td>
<td></td>
</tr>
</tbody>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td>
<button type="button" class="btn btn-default" onclick="additem(); return false">
<b>Tambah</b>

</td>

</table>
And this my script
function additem() {

Any help is appreciated.

You are not passing current id's of inputs to your sum method. and one more thing add jquery onkeyup event to your dynamic inputs. please refer below code -
$(function() {
$('#sample').on('click',additem)
$( "#nama" ).autocomplete({
source: "get_barang.php",
minLength: 2,
select: function( event, ui ) {
$('#kode').val(ui.item.kode);
$('#harga').val(ui.item.harga);
}
});
});
function sum() {
var hrg = document.getElementById('harga').value;
var jml = document.getElementById('jumlah').value;
var result = parseInt(hrg) * parseInt(jml);
if (!isNaN(result)) {
document.getElementById('total').value = result;
}
}
var i = 1;

Incrementing id attribute value through javascript

I am trying to dynamically add rows to a table to take orders and have created a javascript function for it.
function addnewrow()
{
var lastid = $("#table tr:last").attr("id");
var newid=lastid+1;
var newcolumn = document.createElement("tr");
newcolumn.id=newid;
newcolumn.innerHTML = "<td id='no"+newid+"'><a class='cut'>-</a>"+newid+"</td>"+
"<td>"+
"<ajaxToolkit:ComboBox ID='prod"+newid+"' runat='server' DataSourceID='SqlDataSource2' DataTextField='pname' DataValueField='pid' MaxLength='0' style='display: inline;'></ajaxToolkit:ComboBox>" +
"</td>"+
"<td><input type='number' required='required' min='1' name='quantity" + newid + "' /></td>" +
"<td id='price" + newid + "'></td>" +
"<td id='amount" + newid + "'></td>";
document.getElementById("table").appendChild(newcolumn);
}
I am doing this to get the values of all the elements in the code behind file to put them in database.
but due to this i get an error in the aspx.designer.cs page saying semicolon expected
protected global::AjaxControlToolkit.ComboBox prod" + newid + ";
ASP.NET Code
<table class="Grid" id="table">

Check this
$("#btnAddSchedule").click(function () {
var trs = $("[id^=trSchedules]");
var numberofrows = trs.length;
var newtr = $('#' + trs[0].id).clone();
$(newtr).attr('id', $(newtr).attr('id').replace(/\d+/, numberofrows));
newtr.find("input,select,img").each(function () {
$(this).attr('id', $(this).attr('id').replace(/\d+/, numberofrows));
$(this).attr('name', $(this).attr('name').replace(/\d+/, numberofrows));
if ($(this).attr('type') != "hidden") {
$(this).val('');
}
else if ($(this).attr('id').indexOf('DataExportQueueID') == -1) {
$(this).val('');
}
if ($(this).attr("type") == "checkbox") {
$(this).removeAttr("checked");
$(this).parent().html($(this).parent().html().replace(/\d+/g, numberofrows));
}
if ($(this).attr("type") == "button") {
$(this).attr("onclick", "deleteSchedule(this,0);");
}
});
$('#' + trs[numberofrows - 1].id).after(newtr);
CrossCheckScheduleRows();
});
function CrossCheckScheduleRows() {
$('[id^=trSchedules]').each(function () {
var row = $(this);
var index = row[0].rowIndex - 2;
row.attr('id', row.attr('id').replace(/\d+/, index));
row.find("input,select,img").each(function () {
$(this).attr('id', $(this).attr('id').replace(/\d+/, index)).attr('name', $(this).attr('name').replace(/\d+/, index));
});
});
}
I use this for the same purpose, maybe it will help you

jQuery invoice and HTML

I am currently working on a dynamic invoice system for myself. But I can't seem to completely get it working correctly.
I have a invoice table like this in HTML:
Product name -- Quantity -- Tax -- Price (without tax) -- total price
My HTML looks like this:
<td><input type="text" placeholder="Item name" class="form-control" /></td>
<td class="text-center"><input type="number" min="1" id="target" placeholder="Quantity" class="form-control quantity" /></td>
<td class="text-center"><input type="text" placeholder="TAX" class="form-control tax" /></td>
<td class="text-right"><input type="text" placeholder="Price" class="form-control" /></td>
<td class="text-right"><input type="text" disabled placeholder="0,00" class="form-control price" /></td>
I can add rows with this Javascript code:
<script>
function addItem(){
var itemRow =
'<tr>' +
'<td><input type="text" class="form-control" placeholder="Item name" /></td>' +
'<td><input type="text" class="form-control" placeholder="Quantity" /></td>' +
'<td><input type="text" class="form-control tax" placeholder="Tax" /></td>' +
'<td><input type="text" class="form-control" placeholder="Price" /></td>' +
'<td><input type="text" class="form-control price" disabled placeholder="0,00" /></td>' +
'</tr>';
$("#items_table tr:last").after(itemRow);
}
</script>
And I calculate it with this jQuery code:
<script>
var total = 0;
var taxTotal = 0;
(function() {
$('#items_table').on('change', 'input', function() {
if( !$(this).hasClass('tax')) {
totalPrice = 0;
var row = $(this).closest('tr');
// ## Get quantity
var qty = parseFloat(row.find('input:eq(1)').val());
if (qty < 0) {
row.addClass('danger');
return;
} else {
row.removeClass('danger');
}
// ## Get the entered price
var price = parseFloat(row.find('input:eq(3)').val());
if (price < 0) {
row.addClass('danger');
return;
} else {
row.removeClass('danger');
}
// ## Calculate total price
var total = qty * price;
// ## Set total price at the end

Although, its not exactly doing what I want. I want the total price to be at the end of the table row (total price disabled row)
And I want the tax to be added below the invoice (a new table), like this:
Sub total: (Total price without tax)
TAX 10%: (The tax ammount according to the 10%)
TAX 15%: (The tax ammount according to the 15%)
Total: (Sub total price + the tax prices)
But the problem I get is once I have 2 items in the table, and I change the first row's TAX, it gets all messed up.
I am currently out of idea's how to correctly do this. So I all I need is once I filled 1 item row, the tax gets in the total table added, and once I change that tax in that row, it changes below aswell, and the price has to be changed aswell.
Can someone get me back on the right track?

It's not exactly clear what you want to display in the second table,however, I believe the below will suite your needs.
Here is a jsFiddle as well
$('#addRow').click(function () {
addItem();
});
$('#items_table').on('keyup', '.update', function () {
var key = event.keyCode || event.charCode; // if the user hit del or backspace, dont do anything
if( key == 8 || key == 46 ) return false;
calculateTotals();
});
$('#taxPercentage').change(function () {
calculateTotals(); // user changed tax percentage, recalculate everything
});
function calculateTotals(){
// get all of the various input typs from the rows
// each will be any array of elements
var nameElements = $('.row-name');
var quantityElements = $('.row-quantity');
var taxElements = $('.row-tax');
var priceElements = $('.row-price');
var totalElements = $('.row-total');
// get the bottom table elements
var taxPercentageElement =$('#taxPercentage');
var subTotalElement =$('#subTotal');
var totalTaxElement =$('#totalTax');
var grandTotalElement =$('#grandTotal');
var subTotal=0;
var taxTotal=0;
var grandTotal=0;
$(quantityElements).each(function(i,e){
// get all the elements for the current row
var nameElement = $('.row-name:eq(' + i + ')');
var quantityElement = $('.row-quantity:eq(' + i + ')');
var taxElement = $('.row-tax:eq(' + i + ')');
var priceElement = $('.row-price:eq(' + i + ')');
var totalElement = $('.row-total:eq(' + i + ')');
// get the needed values from this row
var qty = quantityElement.val().trim().replace(/[^0-9$.,]/g, ''); // filter out non digits like letters
qty = qty == '' ? 0 : qty; // if blank default to 0
quantityElement.val(qty); // set the value back, in case we had to remove soemthing
var price = priceElement.val().trim().replace(/[^0-9$.,]/g, '');
price = price == '' ? 0 : price; // if blank default to 0
priceElement.val(price); // set the value back, in case we had to remove soemthing
// get/set row tax and total
// also add to our totals for later
var rowPrice = (price * 1000) * qty
subTotal = subTotal + rowPrice;
var tax = taxPercentageElement.val() * rowPrice;
taxElement.val((tax / 1000).toFixed(2));
taxTotal = taxTotal + tax;
var total = rowPrice + tax
totalElement.val((total / 1000).toFixed(2));
grandTotal = grandTotal + total;
});
// set the bottom table values
subTotalElement.val((subTotal / 1000).toFixed(2));

Clone a row in an HTML table and call JavaScript function with the new row

I have a table which has one row in which I multiply two fields, namely quantity and rate/quantity, to get the product total. I have provided a button to add a new row which basically clones the 1st row. Now I want the cloned row to also have the same product as the 1st row. I have tried the following code:
<!DOCTYPE html>
<html>
<h3 align="center">K J Somaiya College Of Engineering, Vidyavihar, Mumbai-400 077</h3>
<h3 align="center">Department Of Information Technology</h3>
<body>
<script>
function WO1() {
var qty = document.getElementById('qty').value;
var price = document.getElementById('price').value;
answer = (Number(qty) * Number(price)).toFixed(2);
document.getElementById('totalprice').value = answer;
}
function WO2() {
var qty = document.getElementById('qty1').value;
var price = document.getElementById('price1').value;
answer = (Number(qty) * Number(price)).toFixed(2);
document.getElementById('totalprice1').value = answer;
}
function WO3() {
var qty = document.getElementById('qty2').value;
var price = document.getElementById('price2').value;
answer = (Number(qty) * Number(price)).toFixed(2);
document.getElementById('totalprice2').value = answer;
}
</script>
<script>

{
var x=document.getElementById("floor").value;

{
alert("Floor must be entered");
return false;
