My validation does not work on added rows and autonumbering

I have a function where i can add rows and autonumbering. The add rows works when you click the "add row" button, and auto numbering works when you press Ctrl+Enter key when there's 2 or more rows. My problem is, my validation does not work on my autonumbering.
For example: when I type manually the "1" on the textbox, it works.
But when I do my auto numbering, "Not good" does not appear on my 2nd
textbox.
Is there anything I missed? Any help will be appreciated.
//this is for adding rows
$("#addrow").on('click', function() {
let rowIndex = $('.auto_num').length + 1;
let rowIndexx = $('.auto_num').length + 1;
var newRow = '<tr><td><input class="auto_num" type="text" name="entryCount" value="' + rowIndexx + '" /></td>"' +
'<td><input name="lightBand' + rowIndex + '" value="" class="form" type="number" /> <span class="email_result"></span></td>"' +
'<td><input type="button" class="removerow" id="removerow' + rowIndex + '" name="removerow' + rowIndex + '" value="Remove"/></td>';
$("#applicanttable > tbody > tr:last").after(newRow);
});
//this is for my validation
$(document).on('change', 'input[name*=lightBand]', function() {
var lightBand1 = $(this).val(); //get value
var selector = $(this) //save slector
selector.next('.email_result').html("") //empty previous error
if (lightBand1 != '') {
/*$.ajax({
url: "<?php echo base_url(); ?>participant/check_number_avalibility",
method: "POST",
data: {
lightBand1: lightBand1
},
success: function(data) {*/
selector.next('.email_result').html("NOT GOOD"); //use next here ..
/* }
});*/
}
});
// this is for autonumbering when ctrl+enter is pressed.
const inputs = document.querySelectorAll(".form");
document.querySelectorAll(".form")[0].addEventListener("keyup", e => {
const inputs = document.querySelectorAll(".form");
let value = parseInt(e.target.value);
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10)) {
inputs.forEach((inp, i) => {
if (i !== 0) {
inp.value = ++value;
}
})
}
});
Add a row and type any number at number textbox column and press ctrl+enter. You'll see the "Not good" is not working on added rows. It'll only work if you enter the number manually per row.

You can call your event handler i.e : change whenever you change your input values by auto numbering . So , use $(this).trigger("change") where this refer to input where value is changed .
Demo Code :
$("#addrow").on('click', function() {
let rowIndex = $('.auto_num').length + 1;
let rowIndexx = $('.auto_num').length + 1;
var newRow = '<tr><td><input class="auto_num" type="text" name="entryCount" value="' + rowIndexx + '" /></td>"' +
'<td><input name="lightBand' + rowIndex + '" value="" class="form" type="number" /> <span class="email_result"></span></td>"' +
'<td><input type="button" class="removerow" id="removerow' + rowIndex + '" name="removerow' + rowIndex + '" value="Remove"/></td>';
$("#applicanttable > tbody > tr:last").after(newRow);
});
//this is for my validation
$(document).on('change', 'input[name*=lightBand]', function() {
var lightBand1 = $(this).val(); //get value
var selector = $(this) //save slector
selector.next('.email_result').html("") //empty previous error
if (lightBand1 != '') {
/*$.ajax({
url: "<?php echo base_url(); ?>participant/check_number_avalibility",
method: "POST",
data: {
lightBand1: lightBand1
},
success: function(data) {*/
selector.next('.email_result').html("NOT GOOD"); //use next here ..
/* }
});*/
}
});
// this is for autonumbering when ctrl+enter is pressed.
$(document).on('keyup', '.form', function(e) {
let value = parseInt(e.target.value);
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10)) {
//loop through all values...
$(".form").each(function(i) {
if (i !== 0) {
$(this).val(++value); //assign new value..
$(this).trigger("change") //call your change event to handle further...
}
})
}
})
Add a row and type any number at number textbox column and press ctrl+enter. You'll see the "Not good" is not working on added rows. It'll only work if you enter the number manually per row.

I want to add new data from second table to main table

I want to add new data to the main table using the checkbox option, but the data added is not the same as the selected data. this is my code ...
<table border="1" id="table2">
<tr>
<td>Raka</td>
<input type="hidden" id="fname" value="Raka">
<td>Gilbert</td>
<input type="hidden" id="lname" value="Gilbert">
<td><input type="checkbox" name="chk"></td>
</tr>
<tr>
<td>Achyar</td>
<input type="hidden" id="fname" value="Achyar">
<td>Lucas</td>
<input type="hidden" id="lname" value="Lucas">
<td><input type="checkbox" name="chk"></td>
</tr>
</table>
<script>
$(document).on('click', '#Add', function() {
$("table").find('input[name="chk"]').each(function(){
if($(this).is(":checked")){
var fname = $('#fname').val();
var lname = $('#lname').val();
var newData = '<tr>'+
'<td>'+fname+'</td>'+
'<td>'+lname+'</td>'+
'<tr>';
$('table').append(newData);
}
});
})
</script>

You need to change your id="fname" to class="fname" and get the input value closest to checkbox. Currently you are getting data from the first inputs as they have the same id's.
function valueExists(value) {
if (!value) {
return true;
}
let exists = false;
$("#main-table").find('tr').each(function() {
let fname = $(this).find("td:nth-child(1)").text(),
lname = $(this).find("td:nth-child(2)").text();
const fullName = `${fname}${lname}`;
if (value.toLowerCase() === fullName.toLowerCase()) {
exists = true;
}
});
return exists;
}
$(document).on('click', '#add', function() {
$("table").find('input[name="chk"]').each(function(e) {
if ($(this).is(":checked")) {
var fname = $(this).parents('tr').find('.fname').val();
var lname = $(this).parents('tr').find('.lname').val();
if (valueExists(`${fname}${lname}`)) return;
var newData = '<tr>' +
'<td>' + fname + '</td>' +
'<td>' + lname + '</td>' +
'<tr>';
$('#main-table').append(newData);
}
});
})

Try this. I have used plain javascript
document.addEventListener("click", function() {
[...document.querySelectorAll("input[name='chk']")].forEach(data => {
console.log(data);
if (data.checked) {
const fname = document.getElementById("fname").value;
const lname = document.getElementById("lname").value;
const newData = `<tr><td>${ fname }</td><td>${ lname }</td</tr>`;
// "<tr>" + "<td>" + fname + "</td>" + "<td>" + lname + "</td>" + "<tr>";
document.getElementById("table2").innerHTML += newData;
}
});
});

Here is a neater solution, using 2 tables as requested, without hidden inputs and a better use of 'tables' and 'trs' in jquery
$(function(){
$("#btnAdd").click(function(){
let table1 = $("#table1");
table2 = $("#table2");
$.each(table2.find('tr'), function(i, tr){
tr = $(tr);
let new_tr = $('<tr>');
if (tr.find("td input").is(":checked")) {
let fname = tr.find("td:nth-child(1)").html(),
lname = tr.find("td:nth-child(2)").html();
new_tr.append(
'<td>' + fname + '</td>' +
'<td>' + lname + '</td>' +
'<td><input type="checkbox" name="chk"></td>'
);
table1.append(new_tr)
}
})
});
});

ı want to do a table or webgrid for my data input help pls.

You must to write something like this
HTML
<div id="tableResult"></div>
JAVASCRIPT - JQUERY
var table = "<table>",
tableEnd = "</table>"
$("#btn1").click(function () {
table += "<tr><td>"+$("#cariKod").val() + "</td></tr>"
table += "<tr><td>"+$("#cariAd").val() + "</td></tr>"
table += "<tr><td>"+$("#Adress").val() + "</td></tr>"
table += tableEnd;
$("#tableResult").html(table)
})

<fieldset>
<table id="dinamiktablo">
<tr>
<td>
<div id="tableResult"></div>
</td>
</tr>
tr += "<tr>";
tr += "<td>" + $("#cariKod").val() + "</td>"
tr += "<td>" + $("#cariAd").val() + "</td>"
tr += "<td>" + $("#Adress").val() + "</td>"
tr += "</tr>";
$("#dinamiktablo").append(tr)
its fixed

Show all names found in table when click display button

$('#btndis').click(function(){
$('ul').empty();
$("#tb").find('tr').each(function(i,el){
var $tds = $(this).find('td');
//for name
$('ul').append("<li>"+$tds.eq(1).text()+"</li>");
});
});

Please check below code.
$("#btndis").on('click',function(){
$("body").append("<ul id='listNames''></ul>");
$('#tb td:nth-child(2)').each(function() {
$("#listNames").append("<li>"+$(this).text()+"</li>")
});
})
Please refer code on this Link. https://jsfiddle.net/gq5f5ux2/2/
On click of the display button iterate loop through all the tr>td-second child to get all the names and then append a UL and LI in the body to display list all the names.

Add a class for colum called "name" and then you can iterate over and select the text in the element
<td class="name">John</td>
Then in JQuery:
$(document).ready(function() {
$('#tb').find('tr').each(function() {
var name = $(this).find('.name').text();
$('#result').append('<p>'+name+'</p>');
});
});

Explanation :
First, we create the ul to store data. Then, we iterate each tr child (td) with a for loop, we create a li and store data into it. It will be displayed in a list, as asked.

Jquery .on(change) event on <select> input only changes first row.

I have a table whereby people can add rows.
There is a select input in the table that when changed, changes the values in a second select field via ajax.
The problem I have is that if a person adds an additional row to the table, the .on(change) event alters the second field in the first row, not the subsequent row.
I've been racking my brain, trying to figure out if I need to (and if so how to) dynamically change the div id that the event binds to and the div that it affects. Is this the solution? If so, could someone please demonstrate how I'd achieve this?
The HTML form is

This prepares the id to be incrementd as we add on new elements. Making use of the class, we can bind a .change() to each of them.
$(document).ready(function() {
$("#add").click(function() {
var newgroup = $('#myassettable tbody>tr:last');
newgroup
.clone(true)
.find("input").val("").end()
.insertAfter('#myassettable tbody>tr:last')
.find(':input')
.each(function() {
this.name = this.name.replace(/\[(\d+)\]/,
function(str, p1) {
return '[' + (parseInt(p1, 10) + 1) + ']';
});
});
var lastId = parseInt(newgroup.find(".chooseSite").attr("id").substring(5), 10);
newId = lastId + 1;
$("#myassettable tbody>tr:last .chooseSite").attr("id", "site-" + newId);
$("#myassettable tbody>tr:last select[id='new-site-" + lastId + "']").attr("id", "new-site-" + newId);
return false;
});
$("#delete").click(function() {
var $last = $('#myassettable tbody').find('tr:last');
if ($last.is(':nth-child(2)')) {
alert('This is the only one');
} else {
$last.remove();
}
});
$(".chooseSite").change(function(event) {
console.log($(this).attr("id") + " changed to " + $(this).val());
var target = "new-" + $(this).attr('id');
/*$.ajax({
type: 'post',
url: 'assetprocess.php',
data: {
get_option: $(this).val()
},
success: function(response) {
$("#" + target).html(response);
}
});*/
var response = "<option>New</option>";
$("#" + target).html(response);
});

Can save some time by setting a counter in global space for the number of Rows, something like var trCount = 1; and use that to set array indexes and IDs. Cloning is fast and easy, but it also means we have to go back and append various attributes. Could also make a function to draw up the HTML for you. Like: https://jsfiddle.net/Twisty/1c98Ladh/10/
function cloneRow(n) {
if (n - 1 < 0) return false;
var html = "";
html += "<tr class='removable' data-row=" + n + ">";
html += "<td><select name='asset[" + n + "][type]' id='type-" + n + "'>";
html += $("#type-" + (n - 1)).html();
html += "<select></td>";
html += "<td><select name='asset[" + n + "][manuf]' id='manuf-" + n + "'>";
html += $("#manuf-" + (n - 1)).html();
html += "<select></td>";
html += "<td><input type='text' placeholder='Serial #' name='asset[" + n + "][serial_num]' id='serial-" + n + "' /></td>";
html += "<td><input type='text' placeholder='MAC Address' name='asset[" + n + "][mac_address]' id='mac-" + n + "' /></td>";
html += "<td><input type='text' placeholder='Name or Desc.' name='asset[" + n + "][description]' id='desc-" + n + "' /></td>";
html += "<td><select name='asset[" + n + "][site]' class='chooseSite' id='site-" + n + "'>";
html += $("#site-" + (n - 1)).html();
html += "<select></td>";
html += "<td><input type='text' placeholder='E.G. Level 3 Utility Room' name='asset[" + n + "][location]' id='loc-" + n + "' /></td>";
html += "<td><select name='asset[" + n + "][contact]' id='contact-" + n + "'><select></td>";
html += "</tr>";
return html;
}
It's more work up front, yet offers a lot more control of each part. And much easier to use later.
