How to loop table HTML in javascript?

I have mockup like this
The HTML table to work with
The table above will calculate subtotal and total_harga using the entered value in jumlah. Calculations work fine, but my code is still using static JavaScript.
If there are a lot of rows in the table, it will be troublesome, if you have to write the getElementById code for all the inputs. How to use looping so that all the inputs can be handled without describing the table rows one by one. This is my HTML and JavaScript.
<div class="container">
<table class="tg" id="sales">
<thead>
<tr>
<th class="tg-0lax">No.</th>
<th class="tg-0lax">Item</th>
<th class="tg-0lax">Jumlah</th>
<th class="tg-0lax">Harga Satuan</th>
<th class="tg-0lax">Diskon Satuan</th>
<th class="tg-0lax">Sub-Total</th>
</tr>
</thead>
<tbody>
<tr>
<td class="tg-0lax">1</td>
<td class="tg-0lax">MIE INSTAN</td>
<td class="tg-keyup"> <input type="text" id="input1" name="fname" onkeyup="CalculationPrice()" placeholder="Masukan jumlah"><br></td>
<td class="tg-0lax" id="harga_satuan1">5000</td>
<td class="tg-0lax" id="diskon_satuan1">500</td>
<td class="tg-0lax" id="sub_total1"></td>
</tr>
<tr>
<td class="tg-0lax">2</td>
<td class="tg-0lax">SUSU UHT</td>
<td class="tg-keyup"><input type="text" id="input2" name="fname" onkeyup="CalculationPrice()" placeholder="Masukan jumlah"><br></td>
<td class="tg-0lax" id="harga_satuan2">6000</td>
<td class="tg-0lax" id="diskon_satuan2">1000</td>
<td class="tg-0lax" id="sub_total2"></td>

<tr>
<td class="tg-0lax">3</td>
<td class="tg-0lax">KERIPIK</td>
<td class="tg-keyup"> <input type="text" id="input3" name="fname" onkeyup="CalculationPrice()" placeholder="Masukan jumlah"><br></td>
<td class="tg-0lax" id="harga_satuan3">8000</td>
<td class="tg-0lax" id="diskon_satuan3">500</td>
<td class="tg-0lax" id="sub_total3"></td>
</tr>
<tr>
<td class="tg-0lax"></td>
<td class="tg-1lax" colspan="4">TOTAL HARGA</td>
<td class="tg-0lax" id="total_price"></td>
</tr>
</tbody>
</table>
this is my code javascript :
function CalculationPrice() {
let input1 = document.getElementById("input1").value;
let input2 = document.getElementById("input2").value;
let input3 = document.getElementById("input3").value;
let hargaSatuan1 = document.getElementById("harga_satuan1").innerText;

let hargaSatuan3 = document.getElementById("harga_satuan3").innerText;
let diskonSatuan1 = document.getElementById("diskon_satuan1").innerText;
let diskonSatuan2 = document.getElementById("diskon_satuan2").innerText;
let diskonSatuan3 = document.getElementById("diskon_satuan3").innerText;
if(input1.length == 0){
let total1 = document.getElementById("sub_total1").innerHTML = 0;
}else if(input1.length > 0){
let subinput = (parseInt(hargaSatuan1) - parseInt(diskonSatuan1)) * parseInt(input1)
let total1 = document.getElementById("sub_total1").innerHTML = subinput;
}
if(input2.length == 0){
let total2 = document.getElementById("sub_total2").innerHTML = 0;
}
else if(input2.length > 0){
let subinput2 = (parseInt(hargaSatuan2) - parseInt(diskonSatuan2)) * parseInt(input2)
let total2 = document.getElementById("sub_total2").innerHTML = subinput2;
}
if(input3.length == 0){
let total3 = document.getElementById("sub_total3").innerHTML = 0;
}
else if(input3 !== null){
let subinput3 = (parseInt(hargaSatuan3) - parseInt(diskonSatuan3)) * parseInt(input3)
let total3 = document.getElementById("sub_total3").innerHTML = subinput3;
}
let total1 = document.getElementById("sub_total1").innerText
let total2 = document.getElementById("sub_total2").innerText
let total3 = document.getElementById("sub_total3").innerText
let total_price = parseInt(total1) + parseInt(total2) + parseInt(total3)
let totalPriceHtml = document.getElementById("total_price").innerHTML = formatRupiah(total_price, "Rp.");
}
function formatRupiah(angka, prefix) {
let number_string = angka.toString().replace(/[^,\d]/g, ""),
split = number_string.split(","),
sisa = split[0].length % 3,
rupiah = split[0].substr(0, sisa),
ribuan = split[0].substr(sisa).match(/\d{3}/gi);
if (ribuan) {
separator = sisa ? "." : "";
rupiah += separator + ribuan.join(".");
}
rupiah = split[1] != undefined ? rupiah + "," + split[1] : rupiah;
return prefix == undefined ? rupiah : rupiah ? "Rp. " + rupiah : "";
}

Using ids on a table makes a lot of unnecessary work, it's much easier to rely on the structure of a static table. And, instead of inline event handlers, we can benefit from event delegation. Here's an example of how to listen input event on tbody and a simple reduce loop to calculate the total sum of subtotals.
const tbody = document.querySelector('#sales'),
rows = Array.from(tbody.rows), // All the rows of the tbody
total = rows.pop().cells[2]; // The TOTAL HARGA cell
function calcTot(e) {
const value = +e.target.value || 0,
rowIndex = e.target.closest('tr').rowIndex - 1, // Constant 1 = the amount of the rows in thead
cells = Array.from(rows[rowIndex].cells),
harga = +cells[3].textContent,
diskon = +cells[4].textContent,
sub = cells[5];
sub.textContent = harga - diskon * value;
total.textContent = rows.reduce((acc, row) => {
return acc += +row.cells[5].textContent;
}, 0);
}
// Calculate the first sums
rows.forEach(row => {
// Call calcTot with a fake event object
calcTot({target: row.cells[2]});
});
tbody.addEventListener('input', calcTot);
<div class="container">
<table class="tg">
<thead>
<tr>
<th class="tg-0lax">No.</th>
<th class="tg-0lax">Item</th>
<th class="tg-0lax">Jumlah</th>
<th class="tg-0lax">Harga Satuan</th>
<th class="tg-0lax">Diskon Satuan</th>
<th class="tg-0lax">Sub-Total</th>
</tr>

<tbody id="sales">

<td class="tg-0lax">1</td>

<td class="tg-keyup"> <input type="text" name="fname[]" placeholder="Masukan jumlah"></td>

Notice also, that I've moved the sales id from the table tag to the tbody tag, and how the event handler function is used to calculate the subtotal and total sums without an actual event by passing an object which contains the needed information of the event object.

First, you should have the data source (in an array of objects). Such as:
var dataSource = [
{ id: 1, item: "MIE INSTAN", HargaSatuan: 5000, DiskonSatuan: 500 },
{ id: 2, item: "SUSU UHT", HargaSatuan: 6000, DiskonSatuan: 1000 },
{ id: 3, item: "KERIPIK", HargaSatuan: 8000, DiskonSatuan: 500 },
]
Then, you can loop through this array to construct your table, using either JQuery or JavaScript's "insertRow()".

var table = document.getElementById("myTable");
dataSource.forEach(function(data, index) {
var row = table.insertRow(index + 1);
var noCell = row.insertCell(0);
var itemCell = row.insertCell(1);
var jumlahCell = row.insertCell(2);
var hargaSatuanCell = row.insertCell(3);
var diskonSatuanCell = row.insertCell(4);
var subTotalCell = row.insertCell(5);
noCell.innerHTML = data.id;

hargaSatuanCell.innerHTML = data.hargaSatuan;
diskonSatuanCell.innerHTML = data.diskonSatuan
})
}

You only need to modify the datasource and refresh the table if there are any new data.
This might not be the best method of doing this, but this will give you a basic understanding on the algorithm and steps required for your needs.

How to enable/disable a row with checkbox?

I am trying to do a form, when you click on checkbox it has to enables the rows of the form, but it's not working...
For example, there's a checkbox above the by clicking it, it has to enable the rest of rows
I'll appreciate any help,
Thanks in advance.

Javascript countdown clock in foreach loop

I would like to display the live countdown clock for each row of my diagram.
and #solicitation.SolicitationResponseDeadLine is the due time for each row.
I can display the countdown, but only for first row(duplicate ID). Please help me. Thank you
<tbody>
#foreach (var solicitation in Model)
{
<tr>
<td scope="row">
<a href="#string.Format(ConfigurationManager.AppSettings["FBOListingLink"], (string) ViewBag.CallingIC, solicitation.SolicitationNumber)" target="_blank">
#solicitation.SolicitationNumber
</a>
</td>
<td>
#solicitation.GetNoticeTypeName()
</td>
<td>
#solicitation.SolicitationTitle
</td>
<td style="width: 15%;">
#*#solicitation.eCPSUser_UserType.AppUser.AppUserFullName*#
#solicitation.PrimaryAssociation.appUser.AppUserFullName
</td>
<td align="center" style="width: 15%;">
#solicitation.SolicitationResponseDeadline
</td>
<td>
<span style="display: block;">#solicitation.SolicitationResponseDeadline</span>
<span class="#countDownCell"></span>
</td>
</tr>
}

#{
var vYear = Convert.ToDateTime(solicitation.SolicitationResponseDeadline).Year;
var vMonth = Convert.ToDateTime(solicitation.SolicitationResponseDeadline).Month;
var vDay = Convert.ToDateTime(solicitation.SolicitationResponseDeadline).Day;
var vMinute = Convert.ToDateTime(solicitation.SolicitationResponseDeadline).Minute;
var vSecond = Convert.ToDateTime(solicitation.SolicitationResponseDeadline).Second;
}
<script type="text/javascript">
var note = "the winter is coming";
var nYear = [#vYear];
var nMonth = [#vMonth];
var nDay = [#vDay];
var nMinute = [#vMinute];
var nSecond = [#vSecond];
tdy = new Date(nYear, nMonth, nDay, nMinute, nSecond);
$("#testCountDown").countdown({

JQuery For each loop with HTML table data

So I have an HTML table that looks like the following.
<div class="timecard">
<h3>tommytest</h3>
<table class="misc_items timecard_list" border="0" cellpadding="2" cellspacing="0" style="margin:0 auto;">
<tbody>
<tr class="display_row odd">
<td align="left" class="job_code" style="color:#000099">2400-Orchard</td>
<td align="right">9:47am</td>
<td align="right">5/19/2014</td>
<td align="right" class="hrs">01:00</td>
</tr>
<tr class="display_odd row">
<td align="left" class="job_code" style="color:#000099">1200-Duffy's</td>
<td align="right">12:37am</td>
<td align="right">5/17/2014</td>
<td align="right" class="hrs">2:00</td>
</tr>
</tbody>
</table>
</div>
<div class="timecard">
<h3>testtest</h3>
<table class="misc_items timecard_list" border="0" cellpadding="2" cellspacing="0" style="margin:0 auto;">
<tbody>
<tr class="display_row odd">
<td align="left" class="job_code" style="color:#000099">2400-Orchard</td>
<td align="right">9:47am</td>
<td align="right">5/19/2014</td>
<td align="right" class="hrs">01:00</td>
</tr>
<tr class="display_odd row">
<td align="left" class="job_code" style="color:#000099">1200-Duffy's</td>
<td align="right">12:37am</td>
<td align="right">5/17/2014</td>
<td align="right" class="hrs">2:00</td>
</tr>
</tbody>
</table>
</div>
<div id="total"></div>
Then I have a jquery script that takes the total "job_code" hours and adds them up for each individual one. However, right now the script combines "tommytest" and "testtest" job codes together. I'm trying to get it to calculate each one individually and print it underneath each's respected table. Any ideas are greatly appreciated.
$(document).ready(function () {
var timeString = $(this).next('td.hrs').text();
var components = timeString.split(':');
var seconds = components[1] ? parseInt(components[1], 10) : 0;
var hrs = parseInt(components[0], 10) + seconds / 60;
total += hrs;
var temp = [];
$('.job_code').each(function (index, element) {
var text = $(this).text();
if (text != 'Out') {
temp.push(text);
}
});
// remove duplicates
var job_code = [];
$.each(temp, function (index, element) {
if ($.inArray(element, job_code) === -1) job_code.push(element);
});
var sum = {};
$.each(job_code, function (index, element) {
var total = 0;
$('.job_code:contains(' + element + ')').each(function (key, value) {
var timeString = $(this).siblings('td.hrs').text();
var components = timeString.split(':');
var seconds = components[1] ? parseInt(components[1], 10) : 0;
var hrs = parseInt(components[0], 10) + seconds / 60;
total += hrs;
sum[index] = {
'job_code': element,
'total': total
};
});
});
console.log(sum);
$.each(sum, function (index, element) {
$('#total').append('<p>Total for ' + element.job_code + ': ' + element.total + '</p>');
});
});

If at all possible I'd like this to be dynamic as there will be more than just these two tables. Thanks ahead of time for the help.

When you query for the TD tags, $(this).next('td.hrs') you are not being specific enough about which table you want the TD tags from. If you are more specific, for example, adding an id to the tables,
<table id="tommytest">...</table>
<table id="testtest">...</table>
then you can query by table like so:
var tdsFromTommytest = $(this).next('#tommytest td.hrs')
var tdsFromTesttest = $(this).next('#testtest td.hrs')
Now that you have the two separate TD lists, you can process how you want. That, I think is the crux of your problem. But hopefully that helps you enough to see how you'd update a separate total tag under each table.

You could do this for tommyTest and subsequently for testtest :
Add id to the individual table
<table id="tommyTest">
And in javascript create different method for calculating the value :
$('#tommyTest').find('.job_code').each(function (index, element) {
var text = $(this).text();
if (text != 'Out') {
temp.push(text);
}
});
