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);
}
});
})

<h1>Main Table</h1>
<table class="table table-dark" border="1" id="main-table">
</table>
<hr>
<h1>Second table</h1>
<table border="1" id="table2">
<tr>
<td class="name">Raka</td>
<input type="hidden" class="fname" value="Raka">
<td class="last">Gilbert</td>
<input type="hidden" class="lname" value="Gilbert">
<td><input class="check" type="checkbox" name="chk"></td>
</tr>
<tr>
<td class="name">Achyar</td>
<input type="hidden" class="fname" value="Achyar">

<input type="hidden" class="lname" value="Lucas">
<td><input class="check" type="checkbox" name="chk"></td>
</tr>
</table>
<button type="button" id="add" name="button">Add</button>

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;
}
});
});
Hope was useful. If any flaws please update

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)
}
})
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
TABLE 1
<table border="1" id="table1">
</table>
<hr/>
TABLE 2
<table border="1" id="table2">
<tr>
<td>Raka</td>
<td>Gilbert</td>
<td><input type="checkbox" name="chk"></td>
</tr>
<tr>
<td>Achyar</td>
<td>Lucas</td>
<td><input type="checkbox" name="chk"></td>
</tr>
</table>

Dynamically Built Jquery Table Assigning Row Data to Variables

I have a table built dynamically in my view, I populated a table with values from a jquery popup modal dialog. What i am trying to accomplish is getting each cell in the row and assigning it to variable, at which point I am going to post the data to the database via an ajax call
I am fairly new to JS and jnquery and following many examples, I cant seem to figure out to assign the cell values to the variable, I have included the code below.
Here is the html for the table
<div class="row">
<div class="col-md-12">
<table id="myTest" class="table table-responsive">
<thead>
<tr>
<th>Sku Number</th>
<th>Product Name</th>
<th style="width:300px">Description</th>
<th>Quantity</th>
<th>Border</th>
<th>Ink Color</th>
<th>Action</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<div style="padding:10px 0; text-align: right; ">
<input id="submit" type="button" value="Save Order" class="btn btn-warning" style="padding: 10px 20px; margin-right: 15px;" />
</div>
</div>
Here is the JS for populating the table
function addItem() {
var remove = $('<input type="button" id="remove" value="remove" style="width:80px" class="btn btn-danger" />');
var td = $("<td></td>");
td.append(remove);
var valid = true;
allFields.removeClass("ui-state-error");
if (valid) {
$("#myTest tbody").append(
"<tr>" +
"<td>" + skuNumber.val() + "</td>" +
"<td>" + productName.val() + "</td>" +
"<td>" + description.val() + "</td>" +
"<td>" + quantity.val() + "</td>" +
"<td>" + border.val() + "</td>" +
"<td>" + inkColor.val() + "</td>" +
"</tr>");
dialog.dialog("close");
$("#myTest > tbody tr:last").append(td);
//console.log(td);
}
return valid;
}
And when you hit the submit button I want to create a list of objects that contains each row in the table, and this is where I am having problems.
$("#submit").click(function () {
var isAllValid = true;
var list = [];
$("#myTest tbody tr td")
.each(function(index, ele) {
var orderItem = {
SkuNumber: skuNumber.val(),
ProductName: productName.val(),
Description: description.val(),
Quantity: quantity.val(),
Border: border.val(),
InkColor: inkColor.val()
};
list.push(orderItem);
console.log(orderItem);
});

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
<form action="assets.php" method="post">
<button type="button" id="add">Add Row</button>
<button type="button" id="delete">Remove Row</button>
<table id="myassettable">
<tbody>
<tr>
<th>Asset Type</th>
<th>Manufacturer</th>
<th>Serial #</th>
<th>MAC Address</th>
<th>Description</th>
<th>Site</th>
<th>Location</th>
</tr>
<tr class="removable">
<!--<td><input type="text" placeholder="First Name" name="contact[0][contact_first]"></td>
<td><input type="text" placeholder="Surname" name="contact[0][contact_surname]"></td>-->
<td><select name="asset[0][type]">
<option><?php echo $typeoption ?></option>
</select></td>
<td><select class="manuf_name" name="asset[0][manuf]">
<option><?php echo $manufoption ?></option>
</select></td>
<td><input type="text" placeholder="Serial #" name="asset[0][serial_num]"></td>
<td><input type="text" placeholder="Mac Address" name="asset[0][mac_address]"></td>
<td><input type="text" placeholder="Name or Description" name="asset[0][description]"></td>
<td><select id="site" name="asset[0][site]">
<option><?php echo $siteoption ?></option>
</select></td>
<td><input type="text" placeholder="e.g Level 3 Utility Room" name="asset[0][location]"></td>
<td><select id="new_select" name="asset[0][contact]"></select></td>
<!--<td><input type="email" placeholder="Email" name="contact[0][email]"></td>
<td><input type="phone" placeholder="Phone No." name="contact[0][phone]"></td>
<td><input type="text" placeholder="Extension" name="contact[0][extension]"></td>
<td><input type="phone" placeholder="Mobile" name="contact[0][mobile]"></td>-->
</tr>
</tbody>
</table>
<input type="submit" value="Submit">
<input type="hidden" name="submitted" value="TRUE" />
</form>
The script I have is
<script type="text/javascript">
$(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)+ ']'
})
})
return false;
});
});
$(document).ready(function() {
$("#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()
}
});
});
$(document).ready(function() {
$("#myassettable").on("change","#site",function(event) {
$.ajax ({
type : 'post',
url : 'assetprocess.php',
data: {
get_option : $(this).val()
},
success: function (response) {
document.getElementById("new_select").innerHTML=response;
}
})
});
});
</script>
and the assetprocess.php page is
<?php
if(isset($_POST['get_option'])) {
//Get the Site Contacts
$site = $_POST['get_option'];
$contact = "SELECT site_id, contact_id, AES_DECRYPT(contact_first,'" .$kresult."'),AES_DECRYPT(contact_surname,'" .$kresult."') FROM contact WHERE site_id = '$site' ORDER BY contact_surname ASC";
$contactq = mysqli_query($dbc,$contact) or trigger_error("Query: $contact\n<br />MySQL Error: " .mysqli_errno($dbc));
if ($contactq){
//$contactoption = '';
echo '<option>Select a Contact (Optional)</option>';
while ($contactrow = mysqli_fetch_assoc($contactq)) {
$contactid = $contactrow['contact_id'];
$contactfirst = $contactrow["AES_DECRYPT(contact_first,'" .$kresult."')"];
$contactsurname = $contactrow["AES_DECRYPT(contact_surname,'" .$kresult."')"];
$contactoption .= '<option value="'.$contactid.'">'.$contactsurname.', '.$contactfirst.'</option>';
echo $contactoption;
}
}
exit;
}
?>
The code is ugly as sin, but this is only a self-interest project at this stage.
Any assistance would be greatly appreciated.
Cheers,
J.

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.

jQuery: How to update row number when first row added?

I've a table like this:
<table class="table table-striped table-bordered table-hover table-condensed" id="table">
<tr>
<td>rowNumber</td>
<td>Product Name</td>
<td>Price</td>
</tr>
<tr>
<td>1</td>
<td>item1</td>
<td>250000</td>
</tr>
<tr>
<td>2</td>
<td>item2</td>
<td>250000</td>
</tr>
</table>
I also adding new row this way (data will be adding to table when new record added):
if ($('#table').length) {
$('#table tr:first').after("<tr>" +
"<td>" + ? + "</td>" +
"<td>" + data.Title + "</td>" +
"<td>" + data.Price + "</td>" +
"</tr>");
}
As you can see, I add new row to the first row of the table. Now I want to add new row with rowNumber 1 then all other rowNumber get update.
Any idea?

Once you have appended the new row, you can set the rowNumber going through all rows (except the first one):
if ($('#table').length) {
$('#table tr:first').after("<tr>" +
"<td></td>" +
"<td>" + data.Title + "</td>" +
"<td>" + data.Price + "</td>" +
"</tr>");
$("#table tr:not(:first-child) td:first-child").each(function(index,item){
$(this).text(index+1);
});
}

jquery live function for adding/removing rows

I' m trying to enable adding/deleting rows to/from table using folowing code:
Script:
$(document).ready(function() {
$('#btnAdd').live('click', function() {
var name = $('#txtName').val();
var name2 = $('#txtName2').val();
$("#tbNames tr:last").append("<tr><td>" + name + "</td><td>" + name2 + "</td><td><simg ssrc='delete.gif' class='delete' height='15' /></td></tr>");
});
$('#tbNames td img.delete').live('click',function() {
$(this).parent().parent().remove();
});
});
HTML
<input id="txtName" type="text" />
<input id="txtName2" type="text" />
<input id="btnAdd" type="button" value="Add" />
<table id="tbNames" >
<tr>
<td>Name</td>
<td>Name2</td>
<td>Delete</td>
</tr>
<tr>
<td>Bingo</td>
<td>Tingo</td>
<td><simg ssrc="Delete.gif" height="15" class="delete" /></td>
</tr>
</table>
Adding works fine, but deleting does not.
It deletes all dynamically added rows behind the clicked one.

I changed the add function from "append" to "after"
$("#tbNames tr:last").after("<tr><td>" + name + "</td><td>" + name2 + "</td><td><img src='delete.gif' class='delete' height='15' /></td></tr>");
And corrected the markup cos it said "simg" instead of "img"
So the compelte solution is
<script type="text/javascript">
$(document).ready(function() {
$('#btnAdd').live
('click',
function() {
var name = $('#txtName').val();
var name2 = $('#txtName2').val();
$("#tbNames tr:last").after("<tr><td>" + name + "</td><td>" + name2 + "</td><td><img src='delete.gif' class='delete' height='15' /></td></tr>");
}
);
$('#tbNames td img.delete').live('click',function() { $(this).parent().parent().remove(); });
}
);
</script>
<input id="txtName" type="text" />
<input id="txtName2" type="text" />
<input id="btnAdd" type="button" value="Add" />
<table id="tbNames" >
<tr>
<td>Name</td>
<td>Name2</td>
<td>Delete</td>
</tr>
<tr>
<td>Bingo</td>
<td>Tingo</td>
<td><img src="Delete.gif" height="15" class="delete" /></td>
</tr>
</table>

You are appending a TR to a TR, it should be appended to the tbody (or table) of the table. or .after() the TR.
$("#tbNames tbody").append("<tr><td>" + name + "</td><td>" + name2 + "</td><td><img src='delete.gif' class='delete' height='15' /></td></tr>")
Also, you should probably specify which parent you are looking for .closest() makes that pretty easy:
$("#tbNames td img.delete").live('click', function() {
$(this).closest('tr').remove();
});
