Calculate the row date depending on previous row in the table

I have this dynamic table. Add more button append a new row. Row consists of number or days and date field. Means how many days added results in date.
Now in the second row, if I add a number of days; it must check the previous previous row date or number and result the date. But rowSelected.prev('tr')[0] gives me no value.
Can anybody please help me.
$(function() {
$("#add-more").click(function() {
$("#main-table").each(function() {
let tds = '<tr>';
jQuery.each($('tr:last td', this), function() {
tds += '<td>' + $(this).html() + '</td>';
});
tds += '</tr>';
if ($('tbody', this).length > 0) {
$('tbody', this).append(tds);
} else {
$(this).append(tds);
}
});
});
$(document).on('change', '.total-days', function(e) {
let rowSelected = $(this).closest('tr');
const someDate = new Date();
someDate.setDate(someDate.getDate() + parseInt($(this).val()));
const newDate = someDate.toISOString().substr(0, 10);
rowSelected.find('.expected-delivery-date').val(newDate);
});
});

Dynamically add row with jQuery

I have an application that integrated with barcode scanner, like this:
I have made a row dynamically with this snippet of code:
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet" id="bootstrap-css">
<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>
<div class="container" align="top" style="margin-top: 0px;">
<h1 align="center">
Barcode: <br><input type="text" id="myHeader" value="5555">
</h1>
<table id="myTable" class=" table order-list">
<thead>
<tr>
<td>Barcode</td>
<td>Item</td>
</tr>
</thead>
<tbody>
</tbody>
<tfoot>
<tr>
<td colspan="7" style="text-align: left;">
<div align="right">
<p style="color: black;margin-right: 90px;">9.999.999</p>
</div>
<input type="button" class="btn btn-lg btn-block " id="addrow" value="Add Row" style="border-color: black;" />
</td>
</tr>
<tr>
</tr>
</tfoot>
</table>
</div>
and here is the code that I wrapped with script tag:
<script >
$(document).ready(function() {
var counter = 0;
$("#addrow").on("click", function() {
var newRow = $("<tr>");
var cols = "";
cols += '<td><input type="text" disabled value="123123123" class="form-control" name="name' + counter + '"/></td>';
cols += '<td><input type="text" disabled value="Sekop" class="form-control" name="mail' + counter + '"/></td>';
cols += '<td><input type="button" class="ibtnDel btn btn-md btn-danger " value="Delete"></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
counter++;
});
$("table.order-list").on("click", ".ibtnDel", function(event) {
$(this).closest("tr").remove();
counter -= 1
});
});
function calculateRow(row) {
var price = +row.find('input[name^="price"]').val();
}
function calculateGrandTotal() {
var grandTotal = 0;
$("table.order-list").find('input[name^="price"]').each(function() {
grandTotal += +$(this).val();
});
$("#grandtotal").text(grandTotal.toFixed(2));
} </script>
But the code above just add the row only when I clicked the Add Row button.
What I want for now is, when I scan a barcode with a barcode scanner, the row automatically added follow the scanned barcode result.
In this case it will be: "When the value on barcode on the header changed ( <h1 align="center">Barcode: 123123123</h1> , the result is same when I clicked the Add Row button.
So, please refer any approach, tutorial or example code how to do that, it would be very appreciated :)
For additional information: The purpose of this app is for cashier app on a store, like when the cashier scan a product, the result automatically appear on the app. And I developing it using Python Flask.

You have to listen to the changes made in the element. You can try with MutationObserver
$(document).ready(function() {
var counter = 0;
$("#addrow").on("click", function() {
var newRow = $("<tr>");
var cols = "";
cols += '<td><input type="text" disabled value="123123123" class="form-control" name="name' + counter + '"/></td>';
cols += '<td><input type="text" disabled value="Sekop" class="form-control" name="mail' + counter + '"/></td>';
cols += '<td><input type="button" class="ibtnDel btn btn-md btn-danger " value="Delete"></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
counter++;
});
$("table.order-list").on("click", ".ibtnDel", function(event) {
$(this).closest("tr").remove();
counter -= 1
});
});
function calculateRow(row) {
var price = +row.find('input[name^="price"]').val();
}
function calculateGrandTotal() {
var grandTotal = 0;
$("table.order-list").find('input[name^="price"]').each(function() {
grandTotal += +$(this).val();
});
$("#grandtotal").text(grandTotal.toFixed(2));
}
// Listen to the changes in the header element and add row
var target = document.querySelector('#myHeader');
setTimeout(function() {
target.textContent = "New Barcode: XXXXXXXXX"; // change text after 2 seconds
}, 2000)
var observer = new MutationObserver(function(mutations) {
mutations.forEach(function(mutation) {
$("#addrow").trigger("click"); // trigger the click event to add row if the header text is changed
});
});
var config = {
attributes: true,
childList: true,
characterData: true
};
observer.observe(target, config);
// otherwise
observer.disconnect();
observer.observe(target, config);
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet" id="bootstrap-css">
<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>
<div class="container" align="top" style="margin-top: 0px;">

Update: The updated question indicates that you can trigger the click event on blur event of the barcode input element:
$(document).ready(function() {
var counter = 0;
$("#addrow").on("click", function() {
var newRow = $("<tr>");
var cols = "";
var barcode = $("#myHeader").val().trim();// take the current barcode value
cols += '<td><input type="text" disabled value= '+ barcode +' class="form-control" name="name' + counter + '"/></td>';
cols += '<td><input type="text" disabled value="Sekop" class="form-control" name="mail' + counter + '"/></td>';
cols += '<td><input type="button" class="ibtnDel btn btn-md btn-danger " value="Delete"></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
counter++;
});
$("table.order-list").on("click", ".ibtnDel", function(event) {
$(this).closest("tr").remove();
counter -= 1
});
});
function calculateRow(row) {
var price = +row.find('input[name^="price"]').val();
}
function calculateGrandTotal() {
var grandTotal = 0;
$("table.order-list").find('input[name^="price"]').each(function() {
grandTotal += +$(this).val();
});
$("#grandtotal").text(grandTotal.toFixed(2));
}
// Add new row by triggering the click event on focus out
var target = document.querySelector('#myHeader');
target.addEventListener('blur', function(){
$("#addrow").trigger("click");
});
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet" id="bootstrap-css">

I think you have problem with your jQuery selector.
Try the code shown above - hope it works for you.

Validate form using Jquery with border and blur effects

I wish to validate a simple table form using jquery. So far I have a for loop that loops through all the fields and checks if they are empty. Then I have another for loop that checks to see if the age is within a certain range. And finally, the last loop checks to see if the email is in the correct RegEx pattern.
Currently only the first loop is working while the others are not being looped through. I have tried to do console.logs and it confirmed that the other loops are not being touched. Any ideas or help would be appreciated!

How the table is created
function GetDynamicTextBox(value1, value2, value3) {
return '<td><input name = "DynamicTextBox" id="name" type="text" value = "" placeholder = "' + value1 + '" class="form-control data" /></td>' +
'<td><input name = "DynamicTextBox" id="age" type="number" min="3" max="100" value = "" placeholder = "' + value2 + '" class="form-control data" /></td>' +
'<td><input name = "DynamicTextBox" id="email" type="email" value = "" placeholder="' + value3 + '" class="form-control data email" /></td>' +
'<td><button type="button" class="btn btn-danger remove"><i class="glyphicon glyphicon-remove-sign"></i></button><button type="button" class="btn btn-success edit"><i class="glyphicon glyphicon-ok"></i></button></td>';
}
When this button is pressed:
$(function () {
$("#btnAdd").bind("click", function () {
var div = $("<tr />");
div.html(GetDynamicTextBox("Enter Name", "Enter Age", "Enter Email"));
$("#TextBoxContainer").append(div);
$('#btnAdd').attr("disabled", "disabled");
$(".data").blur(function() {
validate($(this))
});
});
});

You lacked the relevant piece of code in the question, had to find it in your pen.
In your anonymous "Add Row" function you need to call validation with all of the input fields, using the selector you attempted to use can be done like so:
validate( $( ".data" ) )
Also other issues found in validate method: $(input[i]).val() is a string, convert it to a number using prefix +, +$(input[i]).val()

Duplicating table rows with clone

One table has 3 inputs, the other has 2. When the add button is pushed on either table, I am cloning the table row, which includes cloning a datepicker.
Things have been going fine but now I have a problem. The second table I end everything with 4 e.g. table4, template4, add4 and delete4. I then duplicated the Javascript from the preious table but added 4 to everything (I duplicated it because this table has different inputs). This resulted in the following code.
$(function() {
initJQueryPlugins();
$('#add').on('click', function() {
$last_row = $('#table1 > tbody > tr').last();
if(!hasValues($last_row)){
alert('You need to insert at least one value in last row before adding');
} else {
add_row($('#table1'));
}
});
$('#delete').on('click', function() { delete_row($('#table1')); });
$('#add4').on('click', function() {
$last_row = $('#table4 > tbody > tr').last();
if(!hasValues4($last_row)){
alert('You need to insert at least one value in last row before adding');
} else {
add_row4($('#table4'));
}
});
$('#delete4').on('click', function() { delete_row4($('#table4')); });
});
function add_row($table) {
var tr_id = $table.find('tr').length - 1;
var $template = $table.find('tr.template');
var $tr = $template.clone().removeClass('template').prop('id', tr_id);
$tr.find(':input').each(function() {
if($(this).hasClass('hasDatepicker')) {
$(this).removeClass('hasDatepicker').removeData('datepicker');
}
var input_id = $(this).prop('id');
input_id = input_id + tr_id;
$(this).prop('id', input_id);
var new_name = $(this).prop('name');
new_name = new_name.replace('[0]', '['+ tr_id +']');
$(this).prop('name', new_name);
$(this).prop('value', '');
});
$table.find('tbody').append($tr);
$(".dateControl", $tr).datepicker({
dateFormat: "dd-mm-yy"
});
$(".selectType", $tr).select2({
tags: true
});
}
function hasValues($row){
$optVal = $row.find('td option:selected').text();
$inputVal = $row.find('td input').val();
$textVal = $row.find('td textarea').val();
if($optVal != "" || $inputVal != "" || $textVal != ""){
return true;
} else {
return false;
}
}
function delete_row($table) {
var curRowIdx = $table.find('tr').length - 1;
if (curRowIdx > 2) {
$("#" + (curRowIdx - 1)).remove();
curRowIdx--;
}
}
function add_row4($table4) {
var tr_id = $table4.find('tr').length - 1;
var $template = $table4.find('tr.template4');
var $tr = $template.clone().removeClass('template4').prop('id', tr_id);
$tr.find(':input').each(function() {
if($(this).hasClass('hasDatepicker')) {
$(this).removeClass('hasDatepicker').removeData('datepicker');
}
var input_id = $(this).prop('id');
input_id = input_id + tr_id;
$(this).prop('id', input_id);
var new_name = $(this).prop('name');
new_name = new_name.replace('[0]', '['+ tr_id +']');
$(this).prop('name', new_name);
$(this).prop('value', '');
});
$table4.find('tbody').append($tr);
$(".dateControl", $tr).datepicker({
dateFormat: "dd-mm-yy"
});
}
function hasValues4($row4){
$inputVal = $row4.find('td input').val();
$textVal = $row4.find('td textarea').val();
if($inputVal != "" || $textVal != ""){
return true;
} else {
return false;
}
}
function delete_row4($table4) {
var curRowIdx = $table4.find('tr').length - 1;
if (curRowIdx > 2) {
$("#" + (curRowIdx - 1)).remove();
curRowIdx--;
}
}
function initJQueryPlugins() {
add_row($('#table1'));
add_row4($('#table4'));
}
I have set up a working FIDDLE
The problem is this. If you start adding a few rows in the first table, this all works fine. After this, add a few rows in the second table. This seems to work fine. However, now start deleting rows in the second table. For some reason it seems to also delete rows in the first table.
So my main question is why does this happen? Additionally, is there any way I can do this without duplicating the code? The second table does not use select2.
Thanks

You are deleting this:
$("#" + (curRowIdx - 1)).remove();
This id is also available in the first table, you have to choose a more specified selector
like:
$table4.find("#" + (curRowIdx - 1)).remove();
or better: (comment from K. Bastian above)
$table4.find('tr').last().remove()
I edited your sample here:
https://jsfiddle.net/cLssk6bv/
Here I also deleted the dublicated code, only the different insert method still exist:

Issue with genenerating form fields dynamically

I am using the below script in my python application for generating rows of form fields by clicking an “add row” button. But I am able to do this only if there is at-least one blank row, can I get some help in getting the below script changed so that new row can be added without any blank rows. Also I need to have a timepicker field in the same row
$(function() {
$("div[data-toggle=fieldset]").each(function() {
var $this = $(this);
//alert($this)
//Add new entry
$this.find("button[data-toggle=fieldset-add-row]").click(function() {
var target = $($(this).data("target"))
console.log(target);
var oldrow = target.find("tr[data-toggle=fieldset-entry]:last");
var row = oldrow.clone(true, true);
console.log(row.find(":input")[0]);
var elem_id = row.find(":input")[0].id;
var elem_num = parseInt(elem_id.replace(/.*-(\d{1,4})-.*/m, '$1')) + 1;
row.attr('data-id', elem_num);
row.find(":input").each(function() {
console.log(this);
var id = $(this).attr('id').replace('-' + (elem_num - 1) + '-', '-' + (elem_num) + '-');
$(this).attr('name', id).attr('id', id).val('').removeAttr("checked");
});
oldrow.after(row);
}); //End add new entry
//Remove row
$this.find("button[data-toggle=fieldset-remove-row]").click(function() {
if($this.find("tr[data-toggle=fieldset-entry]").length > -1) {
var thisRow = $(this).closest("tr[data-toggle=fieldset-entry]");
thisRow.remove();

//End remove row

try this its working..
