How can I get only one column value from html table?

I have a html table that shows a list of users ID, Name and E-mail. When my user clicks in any row, I get the id number of that row and send to my backend. So, I did this:
//Making the table
var trs = document.getElementsByTagName('tr');
for (var i = 0; i < trs.length; i++) {
trs[i].onclick = clickHandler;
}
Function that handles the click:
function clickHandler(event) {
var numb = this.innerText.match(/\d/g);
numb = numb.join("");
window.location.replace("chooseParticipant.php?id="+numb);
}
Table Example:
<div id="table">
<table>
<thead>
<tr>
<th>ID</th>
<th>Name</th>
<th>E-mail</th>
</tr>
</thead>
<tbody>
<td>7</td>
<td>Test User</td>
<td>testuser123#example.com</td>
</tbody>
</table>
</div>
What happens then? If an user have numbers in their e-mail, the "numb" variable gets these numbers too. I don't know how to filter only the id number. Did someone have any ideas?

You could assign a class to you tag.
Something like below:-
<td class="id">7</td>
And in the javascript code you could fetch all the elements with class "id".
And then perform your click handler on each one.
var trs = document.getElementsByClassName('id');
I hope this helps.

Try this code snippet which use data-* attribute
document.addEventListener('DOMContentLoaded', function(e) {
var trs = document.querySelectorAll('#table tbody tr');
var repeater = Array.prototype.slice;
repeater.call(trs).forEach(function(tr) {
tr.addEventListener('click', function(e) {
var data = tr.querySelector('td[data-id]').dataset;
console.log('id=', data.id);
});
});
});
tbody {
cursor: pointer;
}
<div id="table">
<table border="1" cellspacing="0" cellpadding="3">
<thead>
<tr>
<th>ID</th>
<th>Name</th>
<th>E-mail</th>
</tr>
</thead>
<tbody>
<tr>
<td data-id="7">7</td>
<td>Test User 1</td>
<td>testuser1231#gmail.com</td>
</tr>
<tr>
<td data-id="8">8</td>
<td>Test User 2</td>
<td>testuser1232#gmail.com</td>
</tr>
<tr>
<td data-id="9">9</td>
<td>Test User 3</td>
<td>testuser1233#gmail.com</td>
</tr>
</tbody>
</table>
</div>

How can I target a table cell in the same row with jQuery?

I have a table with a single input field and an AJAX script that runs when the input field value is modified. This is all working well. I now need to extend this to insert a date into another cell in the same row, but now sure how to target this as the ID will have to be dynamic. Here's the current table:
<table class="table table-condensed table-striped table-bordered">
<thead>
<th class="text-center" scope="col">Order Number</th>
<th class="text-center" scope="col">Order Date</th>
<th class="text-center" scope="col">Con Note</th>
</thead>
<tbody>
<tr>
<td>123456</td>
<td id="85759.OrderDate"></td>
<td id="85759"><input type="text" class="form-control" placeholder="Con Note" name="conNote" value=""></td>
</tr>
<tr>
<td>987654</td>
<td id="85760.OrderDate"></td>
<td id="85760"><input type="text" class="form-control" placeholder="Con Note" name="conNote" value=""></td>
</tr>
</tbody>
</table>
I need to insert the current data into the Order Data cell when the AJAX script is run, something like this:
$("#85759.OrderDate").html('current date');
but not sure how to dynamically target the Order Data cell? I'm setting the ID for the Order Data cell to be the same ID as the input field with ".OrderDate" appended. Current script is:
$(document).ready(function() {
$("input[type='text']").change(function() {
var recid = $(this).closest('td').attr('id');
var conNote = $(this).val();
$this = $(this);
$.post('updateOrder.php', {
type: 'updateOrder',
recid: recid,
conNote: conNote
}, function(data) {
data = JSON.parse(data);
if (data.error) {
var ajaxError = (data.text);
var errorAlert = 'There was an error updating the Con Note Number - ' + ajaxError;
$this.closest('td').addClass("has-error");
$("#serialNumberError").html(errorAlert);
$("#serialNumberError").show();
return; // stop executing this function any further
} else {
$this.closest('td').addClass("has-success")
$this.closest('td').removeClass("has-error");
}
}).fail(function(xhr) {
var httpStatus = (xhr.status);
var ajaxError = 'There was an error updating the Con Note Number - AJAX request error. HTTP Status: ' + httpStatus;
$this.closest('td').addClass("has-error");
//display AJAX error details
$("#serialNumberError").html(ajaxError);
$("#serialNumberError").show();
});
});
});

You can get the parent element 'tr' and then find the 'td.OrderDate', I suggest you to use a class to identify the td in the context of its parent.
$(function () {
$("input[type='text']").change(function() {
var parent = $(this).parents('tr');
// Get any element inside the tr
$('td.OrderDate', parent).text('[current date]')
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td>987654</td>
<td id="85760.OrderDate" class="OrderDate"></td>
<td id="85760"><input type="text" class="form-control" placeholder="Con Note" name="conNote" value=""></td>
</tr>
</table>

You can select the cell by $this.closest('tr').children('td[id$="OrderDate"]').
You can simplify it more by:
Instead of using attribute ends with selector ([id$=".."]), if you can, add a CSS class "OrderDate" for example to all the order date cells, and simplify the selector to $this.closest('tr').children('.OrderData')
Instead of closest() use parents(). This is a micro-optimization. The only difference is that closest tests the actual element itself for matching the selector, and in this case you know you only need to check parent elements
You can also optionally rely on the fact that the cells are siblings and instead of children use siblings like like$this.parents('td').siblings('.OrderDate')

Check the code below. I've removed the ajax call and replaced it with the success block, but the concept is still the same. It gets the cell that has an id that ends with "OrderDate" on the same row and sets the html for that cell. I've used the jQuery Ends With selector for this.
$(document).ready(function() {
$("input[type='text']").change(function() {
var recid = $(this).closest('td').attr('id');
var conNote = $(this).val();
var $this = $(this);
$this.parents('tr:first').find("td[id$='OrderDate']").html(new Date());
$this.closest('td').addClass("has-success")
$this.closest('td').removeClass("has-error");
});
});
.has-success {
border: 1px solid green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="table table-condensed table-striped table-bordered">
<thead>
<th class="text-center" scope="col">Order Number</th>
<th class="text-center" scope="col">Order Date</th>
<th class="text-center" scope="col">Con Note</th>
</thead>
<tbody>
<tr>
<td>123456</td>
<td id="85759.OrderDate"></td>
<td id="85759"><input type="text" class="form-control" placeholder="Con Note" name="conNote" value=""></td>
</tr>
<tr>
<td>987654</td>
<td id="85760.OrderDate"></td>
<td id="85760"><input type="text" class="form-control" placeholder="Con Note" name="conNote" value=""></td>

get the values of all cells in table row using jquery

I would like to get the values in each cell in table row which is selected using a checkbox.
Scenario: Whenever user clicks the show table button, my page is dynamically loaded with some data from tables, which has columns like checkbox, Item name, Item code, Quantity, Rejected and Accepted. Now I want to get the values of selected rows when the user clicks the button called "save".
<script type="text/javascript">
$(document).ready(function() {
$("#tablediv").hide();
$("#showTable").click(function(event){
$.post('PopulateTable',{grn : $('#grn').val()},function(responseJson) {
if(responseJson!=null){
$("#itemtable").find("tr:gt(0)").remove();
var table1 = $("#itemtable");
$.each(responseJson, function(key,value) {
var rowNew = $("<tr><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr>");
rowNew.children().eq(0).html('<input type="checkbox" />');
rowNew.children().eq(1).text(value['itemname']);
rowNew.children().eq(2).text(value['itemcode']);
rowNew.children().eq(3).text(value['supplier']);
rowNew.children().eq(4).text(value['receivedqty']);
rowNew.children().eq(5).html('<input type="text" class="tb2"/>');
rowNew.children().eq(6).html('<input type="text" class="tb2"/>');
rowNew.children().eq(7).html('<input type="text" class="tb2"/>');
rowNew.appendTo(table1);
});
}
});
$("#tablediv").show();
});
});
<br/>
<div id="tablediv">
<table cellspacing="0" id="itemtable" align="center">
<tr>
<td><input type="checkbox" /></td>
<th scope="col">Item name</th>
<th scope="col">Item code</th>
<th scope="col">Supplier</th>
<th scope="col">Received qty</th>
<th scope="col">Accepted qty</th>
<th scope="col">Rejected qty</th>
<th scope="col">Remarks</th>
</tr>
</table>
</div>
$(document).ready(function(){
// code to read selected table row cell data (values).
$("#itemtable").on('click','.btnSelect',function(){
// get the current row
alert("i am inside select");
// get the current row
var currentRow=$(this).closest("tr");
var col1=currentRow.find("td:eq(0)").text(); // get SI no from checkbox
var col2=currentRow.find("td:eq(1)").text(); // get item name
var col3=currentRow.find("td:eq(2)").text(); // get item code
var col4=currentRow.find("td:eq(3)").text(); // get supplier
var col5=currentRow.find("td:eq(4)").text(); // get received qty
var col6=currentRow.find("td:eq(5)").text(); // get accepted qty
var col7=currentRow.find("td:eq(6)").text(); // get rejected qty
var col8=currentRow.find("td:eq(7)").text(); // get remarks
var data=col1+"\n"+col2+"\n"+col3+"\n"+col4+"\n"+col5+"\n"+col6+"\n"+col7+"\n"+col8;
alert(data);
});
});
<!--btnSelect is class of checkbox -->

I come across below exaple to get all value of table cell of checked row.
$('.chk').change(function () {
if($(this).is(':checked'))
{
$(this).closest('tr').find('td').each(
function (i) {
console.log($(this).text());
});
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="tablediv">
<table border="1" id="itemtable" align="center">
<tr>
<th>check</th>
<th scope="col">Item name</th>
<th scope="col">Item code</th>
<th scope="col">Supplier</th>
<th scope="col">Received qty</th>
<th scope="col">Accepted qty</th>
<th scope="col">Rejected qty</th>
<th scope="col">Remarks</th>
</tr>
<tr>
<td><input type="checkbox" class="chk" ></td>
<td>Pencil</td>
<td>101</td>
<td>Supplier</td>
<td>10</td>
<td>5</td>
<td>5</td>
<td>Remarks</td>
</tr>
<tr>
<td><input type="checkbox" class="chk" ></td>
<td>Pen</td>
<td>102</td>
<td>Supplier</td>
<td>25</td>
<td>20</td>
<td>5</td>
<td>Remarks</td>
</tr>
</table>
</div>

First give "name" to your checkbox, such as :
<input type="checkbox" name="case[]" />
JS code:
var values = new Array();
$("#saveButton").click(function(){
$.each($("input[name='case[]']:checked"), function() {
var data = $(this).parents('tr:eq(0)');
values.push({ 'Item name':$(data).find('td:eq(1)').text(), 'Item code':$(data).find('td:eq(2)').text() , 'Supplier':$(data).find('td:eq(3)').text()});
});
console.log(JSON.stringify(values));
});

Cloning closest table row

I recently asked this question
Since then I have discovered that what I wanted to do wont work. This is because the table is generated by a for loop, with their id incrementing each time. As such, I needed to amend things so that it would add rows for the table it is supposed too. I have updated my fiddle to show an example with two table JSFiddle
Essentially, I now do this
$(function() {
$(".addCF").click(function(){
var clone = $(this).closest('tr').clone(true).insertAfter($(this).closest('tr'));
});
$("#customFields").on('click','.remCF',function(){
$(this).parent().parent().remove();
});
});
I can get the name and label of the cloned rows done myself using the previous examples. My main problem is that I do not want to clone the whole row. At the moment, it is cloning this
<tr>
<td><label class="subjectline" for="User1">User NOC M1</label></td>
<td id="slLabel">SL_A</td>
<td id="slInput"><input type="text" name="slOptions[User][NOC M1]" class="form-control" id="User1"></td>
<td><a class="addCF" href="javascript:void(0);">+ additional user</a></td>
</tr>
I need it to clone this but make the first td empty. Additionally, like the initial question, the last td should be a close button
Remove
Is it possible to do this?
Thanks

From the cloned tr,
empty its first-child(td) 's content.
Set its last-child(td) 's html as the close element's html,
$(function() {
$(".addCF").click(function(){
var clone = $(this).closest('tr').clone(true);
$("td:first-child", clone).empty();
$("td:last-child", clone).html('Remove');
clone.insertAfter( $(this).closest('tr'));
});
$("table.table").on('click','.remCF',function(){
$(this).parent().parent().remove();
});
});
DEMO

You need to change your Cloned TR's html:
HTML:
<table id="customFields1" class="table table-bordered table-hover additionalMargin alignment">
<thead>
<tr>
<th colspan="2"></th>
<th>Some Title</th>
</tr>
</thead>
<tbody>
<tr>
<td><label class="subjectline" for="User1">User NOC M1</label></td>
<td id="slLabel">SL_A</td>
<td id="slInput"><input type="text" name="slOptions[User][NOC M1]" class="form-control" id="User1"></td>
<td><a class="addCF" href="javascript:void(0);">+ additional user</a></td>
</tr>
</tbody>
</table>
<table id="customFields2" class="table table-bordered table-hover additionalMargin alignment">
<thead>
<tr>
<th colspan="2"></th>
<th>Some Title</th>
</tr>
</thead>
<tbody>
<tr>
<td><label class="subjectline" for="User1">User NOC M1</label></td>
<td id="slLabel">SL_A</td>
<td id="slInput"><input type="text" name="slOptions[User][NOC M1]" class="form-control" id="User1"></td>
<td><a class="addCF" href="javascript:void(0);">+ additional user</a></td>
</tr>
</tbody>
</table>
JQUERY:
$(function() {
$(".addCF").click(function(){
var closest_tr =$(this).closest('tr').clone(true);
closest_tr = $(closest_tr).find("td:first").html("").parent();
var clone = closest_tr.insertAfter( $(this).closest('tr'));
});
$("#customFields").on('click','.remCF',function(){
$(this).parent().parent().remove();
});
});
DEMO: https://jsfiddle.net/116hvkhe/

is this something you were looking for: https://jsfiddle.net/8zwf9njr/13/
$(".addCF").click(function(){
var clone = $(this).closest('tr').clone(true);
clone.find('td:first-child').html('');
clone.find('td:last-child').html('Remove');
clone.insertAfter( $(this).closest('tr'));
});
you find the first td element of the clone and empty it.
then you find the last td of the clone and you replace whatever is in it with your remove button.
ps. i think there's also a typo in your original remove click code:
it should be $("#customFields1").on('click', instead of just #customFields. alternatively you can target both tables by using a more generic selector like table or add a class to the tables and use that.

How to copy the contents of one row in a table to another table and add the identical ones

var Sell_Button = document.getElementById('sellbtn'),
secondTable = document.getElementById("secondTableBody");
Sell_Button.addEventListener('click', function() {
var Row = secondTable.insertRow();
for (var c = 0; c < 2; c += 1) {
Row.insertCell(c);
}
Row.cells[0].innerHTML = this.parentNode.parentNode.cells[0].innerHTML;
Row.cells[2].innerHTML = this.parentNode.parentNode.cells[1].innerHTML;
//checks to see if the secondTable has a row containing the same name
for (var f = 0; f < secondTable.rows.length; f += 1) {
//adds only the sold amount if the second table has a row with the same name
//error
if (secondTable.rows[f].cells[0].innerText === this.parentNode.parentNode.cells[0].innerText) {
secondTable.rows[f].cells[1].innerHTML = +this.parentNode.parentNode.cells[2].innerHTML;
//deletes an extra row that is added at the bottom
if (secondTable.rows.length > 1) {
secondTable.deleteRow(secondTable.rows.length - 1);
}
//if nothing matched then a new row is added
} else {
secondTable.insertRow();
Row.cells[0].innerHTML = this.parentNode.parentNode.cells[0].innerHTML;
Row.cells[1].innerHTML = this.parentNode.parentNode.cells[2].innerHTML;
}
}
}

Ok, this example isn't exactly what i'm working on but it's very similar. The only difference is that in mine the rows and buttons are dynamically added by the user and he inserts the details. What I want is that when i press on the button of each row (sell) the details (Item and Sold only) are copied into a row in the second table and checks if the same item exists in this second table if so then it adds the amount of sold of both items in one row. For instance I press on the first row button the Apples it copies the listed above details to the second table in a row and then when i click on the button of the second row (Apples also) it only adds the sold amount up and doesn't add a second apples row because an apples row already exists in the second table but when i click on the oranges button it makes a new row because the oranges row doesn't exist. So how do I do this in JavaScript? i hope i was thorough and made any sense. I have no idea why the code isn't working here but i hope you get the point. This code works perfectly just as i want it to until for some reason i get this error: Cannot read property 'innerText' of undefined when i press the buttons approx. 6-7 times targeting the if statement where i commented error.

This sets a click handler to all buttons. If the row doesn't exist in the second table it's created. It sets a data-type referring to the item. When somebody clicks the sell button again and there is a row containing the data-type the row is updated instead of created. All in plain JavaScript.
var Sell_Button = document.querySelectorAll('.sellbtn'),
secondTable = document.getElementById("secondTableBody");
Array.prototype.slice.call(Sell_Button).forEach(function(element){
element.addEventListener('click', function(e) {
//since the button is an element without children use e.
var clickedElement = e.target;
var parentRow = clickedElement.parentNode.parentNode;
//check if second table has a row with data-type
var rowWithData = secondTable.querySelector("[data-type='"+parentRow.cells[0].childNodes[0].nodeValue+"']");
if (rowWithData)
{
rowWithData.cells[1].innerHTML = parseInt(rowWithData.cells[1].childNodes[0].nodeValue) + parseInt(parentRow.cells[2].childNodes[0].nodeValue);
}
else
{
var Row = secondTable.insertRow();
Row.setAttribute("data-type", parentRow.cells[0].childNodes[0].nodeValue);
for (var c = 0; c < 2; c += 1) {
Row.insertCell(c);
}
Row.cells[0].innerHTML = parentRow.cells[0].childNodes[0].nodeValue;
Row.cells[1].innerHTML = parentRow.cells[2].childNodes[0].nodeValue;
}
});
});

Do you mean something like:
$(document).on("click", "#firstTable tr button", function(b) {
b = $(this).closest("tr");
var d = $.trim(b.find("td:first").text());
b = parseFloat($.trim(b.find("td:nth-child(3)").text()));
var a = $("#secondTable"),
c = a.find("tr").filter(function(a) {
return $.trim($(this).find("td:first").text()) == d
});
c.length ? (a = c.find("td:nth-child(2)"), c = parseFloat($.trim(a.text())), a.text(b + c)) : (a = $("<tr />").appendTo(a), $("<td />", {
text: d
}).appendTo(a), $("<td />", {
text: b
