Why the text generated from the previous table row of number cannot be displayed in the next table row?

Here's another problem encountered with js/html code. I typed some numbers at the top of the page, then after I pressed the button First Line, it will display the numbers I inputted in the first table row accordingly. If I press the button Last Line, I'd like it to display some numbers after getting done with some arithmetics, which is in the btn2 part in the js file, in the last table row of the page. I'd like to find out if it is the problem of innerHTML or valueAsNumber in the if statements, or the variables declared in the for loop not applicable in the later if statements, that caused the numbers in the last row cannot be displayed eventually.
The for loop and the if statement is intended for the page to scan the numbers inputted in the first row, do some arithmetics with them, and display them in the last row, in each respective cell. Is there any other way out to do so?
Thank you very much!

So you can Iterate the td by iterating the elements HTMLCollection property of the tr. Iterate two Iterables by using the index from one.
const tab = document.getElementById("tab");
const btn1 = document.getElementById('btn1');
const btn2 = document.getElementById('btn2');
const firstRow = tab.firstElementChild.children[1].children;
const secondRow = tab.firstElementChild.children[2].children;
btn1.addEventListener('click', () => {
for (var i = 0; i <= 7 /* <- This is a magic value - avoid these */; i++) {
let row = tab.rows[1];
let c = row.cells[i];
let inpId = 'inp' + (i + 1);
let inpEl = document.getElementById(inpId);
c.innerHTML = inpEl.value;
}
});
btn2.addEventListener('click', () => {
[...secondRow].forEach((el,index)=>{
//let group = Math.floor(index / 4);
let inp = parseInt(firstRow[index].innerText, 10);
if (!inp) return;
let choices = [0, inp, (inp + 2), (inp - 2)];
let x = (Math.floor(Math.random() * choices.length) + 7) % 7;
el.innerText = x;
})

Some additional advice:
I couldn't be bothered to clean up all of your code, next time please provide a Minimal Example, tree fields would have been plenty to ask the question.
Further please avoid magic numbers, like you use in your loops. Get the size of what you are iterating when you use it. This makes your code more flexible and reusable.
In the same vein: Please do not throw ids everywhere. They just beg to break your code if you ever try to reuse it somehow.

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">

}
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);

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>

</tr>

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
})
}
myFunction()
</script>

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...

How to get value of checkbox in table?

How can I get value of checkbox in table? I want use it for in this case in order get parameter. Now, please see html table:
<table id="div_func" class="table table-bordered" style="width: 100%">
<thead>
<tr>
<th>
<input type="checkbox" id="chk_all" /></th>
<th>Name</th>
</tr>
</thead>
<tbody>
<tr>
<td> <input type="checkbox" class="checkbox1" id="chk" name="check[]" value="D01" /></td>
<td>Banana </td>
</tr>
<tr>
<td> <input type="checkbox" class="checkbox1" id="chk" name="check[]" value="D02" /></td>
<td>Orange </td>
</tr>
<tr>
<td> <input type="checkbox" class="checkbox1" id="chk" name="check[]" value="D03" /></td>
<td>Apple </td>
</tr>
</tbody>
</table>
And this is my script , I use for get value in checkbox , then put parameter
function add_funcgroup() {
var func_group = [];
var chk_allow = "";
var table = document.getElementById("div_func");
for (var i = 0; i < table.rows.length; i++) {
if ($('#chk')[i].is(':checked')) {
chk_allow = "True";
}
else {
chk_allow = "False";
}
var group_func = {
GROUP_MOD_ID: id_temp,
FUNCTION_MOD_ID: $('#chk')[i].val(),
ALLOW: chk_allow
};
func_group[i] = group_func;
}
var func_group_temp = {
FUNC_MOD: func_group
};
var DTO = {
'func_group_temp': func_group_temp
};
$.ajax(
{
And it's not working.

What you have done is right, but you are not outputting it to the table!
var table = $("#div_func");
var value_check = "";
for (var i = 1; i < table.rows.length; i++) {
if ($('#chk')[i].is(':checked')) {
value_check += i + ": " + $('#chk')[i].val();
}
}
alert(value_check);
And you aren't appending it, instead saving!

Try to this
$('#div_func tbody tr input:checkbox').each(function() {
if (this.checked) {
//Do something
}
});.

Not getting input inside td with jQuery?

I have a problem not getting the <input> inside a specified <td>. Through jQuery, I want once an "input search" entered, get just those <tr> that have these entries.Then when the input is empty return all the entries.
Here is my code :
<table id="hosts">
<tr>
<th>First</th>
<th>Second</th>
</tr>
<tr>
<td id="host"><input type="text" id="inputhost" value="214215" size="16"></td>
<td id="rand"><input type="text" id="inputrand" value="442" size="16"></td>
</tr>
<tr>
<td id="host"><input type="text" id="inputhost" value="1252512" size="16"></td>
<td id="rand"><input type="text" id="inputrand" value="556" size="16"></td>
</tr>
<tr>
<td id="host"><input type="text" id="inputhost" value="2114" size="16"></td>
<td id="rand"><input type="text" id="inputrand" value="4666" size="16"></td>
</tr>
<tr>
<td id="host"><input type="text" id="inputhost" value="3245466" size="16"></td>
<td id="rand"><input type="text" id="inputrand" value="22654" size="16"></td>
</tr>
<tr>
<td id="host"><input type="text" id="inputhost" value="24588" size="16"></td>
<td id="rand"><input type="text" id="inputrand" value="54877" size="16"></td>
</tr>
</table>
<br />
<input type="text" id="search" placeholder=" live search"></input>
and this is my jQuery code:
function removeHighlighting(highlightedElements) {
highlightedElements.each(function () {
var element = $(this);
element.replaceWith(element.html());
})
}
function addHighlighting(element, textToHighlight) {
var text = element.text();
var highlightedText = '<em>' + textToHighlight + '</em>';
var newText = text.replace(textToHighlight, highlightedText);
element.html(newText);
}
$("#search").on("keyup", function () {
var value = $(this).val();
removeHighlighting($("table tr em"));
$("#hosts tr").each(function (index) {
if (index !== 0) {
$row = $(this);
var $host = $row.find("#host input#inputhost");
var $dest = $row.find("#rand input#inputrand");
var host_id = $host.text();
var dest_id = $dest.text();
var hostIndex = host_id.indexOf(value);
var destIndex = dest_id.indexOf(value);
if ((hostIndex == -1) && (destIndex == -1)) {
$row.hide();
}
else if ((hostIndex != -1) && (destIndex != -1)) {
addHighlighting($host, value);
addHighlighting($dest, value);
$row.show();
}
else if (hostIndex != -1) {
addHighlighting($host, value);
$row.show();
}
else {
addHighlighting($dest, value);
$row.show();
}
}
});
});

Duplicate IDs! You don't really need them; remove them and then your code will be:
var $host = $row.find("td:first input");
var $dest = $row.find("td:eq(1) input");
UPDATE
You also have to update your code to:
var host_id = $host.val();
var dest_id = $dest.val();
DEMO

You cant give Id like that. Id should be unique. change them to class. then it will work. Then your selector will be
$(this).find(".host input.inputhost")
