Appended new row is not behaving like previous one (row)

Question

I have a HTML table in side which i have several td as input field,my table is dynamic, when page loads i am appending the 1st row of my table and

Answer 1

I think you should assign a variable to the table:

document. getElementById('I'd of table body');

To create the record build it as elements:

document.createElement('tr'), document.createElement('td'); Append to to tr. repeat as necessary...

Then append the new record element to the table body. Each element may be added to, such as adding attributes like class or events.

For this final record event add an on blur handler. document.addEventHandler('blur', function callback);

Answer 2

You can assign the element selector target in this case markup. You have to add the listener again after you create a new DOM element.

function rowappend() // this one is appending row
{
  var markup = $('<tr><td><input type="text" class="form-control commantd"name="itemNametd" id="itemNametd">' +
    '</td><td id="itemCodetd" class="commantd"></td>' +
    '<td><input type="text" class="form-control commantd"name="unitQtytd" id="unitQtytd"></td>' +
    '<td id="purRatetd" class="commantd"></td>' +
    '<td><input type="text" class="form-control commantd"name="discPercentagetd" id="discPercentagetd"></td>' +
    '<td id="discAmttd" class="commantd"></td>' +
    '<td id="gstPercentagetd" class="commantd"></td>' +
    '<td id="gstAmttd" class="commantd"></td>' +
    '<td id="totalAmttd" class="commantd"></td></tr>');
    
  $("table tbody").append(markup);
  $("#itemNametd",markup).focus();
}
rowappend()


var data = [ //data to populate Item Name search input field
  {
    "ItemName": "Butter"
  },
  {
    "ItemName": "Rice"
  },
  {
    "ItemName": "Milk"
  },
  {
    "ItemName": "Ice Cream"
  },
  {
    "ItemName": "Curd"
  }
]
var data1 = [{ // this data will be dynamic but for now to test i am using this single data
  "ItemName": "Butter",
  "ItemCode": 400564,
  "PurRate": 8,
  "DiscAmt": 6,
  "gstPercentage": 35,
  "gstAmt": 5
}]
var totalAmount = "";
var unitQuantity = "";
$(function() {
  let itemName = data.map(value => { //using autocomplete to for searching input field

    return value.ItemName;
  });
  $("#itemNametd").autocomplete({
    source: itemName
  });
});
$("#itemNametd").focusout(function() { //when user focus out from Item Name doing this

  data1.map(value => {
    $("#itemCodetd").text(value.ItemCode);
    $("#purRatetd").text(value.PurRate);
    $("#discAmttd").text(value.DiscAmt);
    $("#gstPercentahgetd").text(value.gstPercentage);
    $("#gstAmttd").text(value.gstAmt);

  });

});
$("#unitQtytd").focusout(function() { //when user focus out Unit Qty doing some calculation
  unitQuantity = $("#unitQtytd").val();
  purchaseRate = $("#purRatetd").text();
  totalAmount = (parseInt(unitQuantity) * parseInt(purchaseRate));
  $("#totalAmttd").text(totalAmount);

});

    $('body').on('focusout','#discPercentagetd', function(){
      rowappend()
});

Answer 3

There are several issues with your code

The two most important are

• You use multiple elements with the same id. But ids must be unique. JavaScript/jQuery will always use the first element with the id if multiple elements have the same (CSS is different). I used name instead of id here
• You add event listeners to elements, which are not there at run-time. Only the first input-row is created, when you listen to the focusout events. I listen to the focusout event on the whole document. If you focus out of an input, the event will bubble up to the document, where I decide, what to do based on the event's target property.

I restructured your code a bit and made some improvements, but it's far from perfect.

"use strict";
console.clear()


const data = [ //data to populate Item Name search input field
  {"ItemName": "Butter"},
  {"ItemName": "Rice"},
  {"ItemName": "Milk"},
  {"ItemName": "Ice Cream"},
  {"ItemName": "Curd"}
]

const data1 = {// this data will be dynamic but for now to test i am using this single data
  butter: { 
    "ItemName": "Butter",
    "ItemCode": 400564,
    "PurRate": 8,
    "DiscAmt": 6,
    "gstPercentage": 35,
    "gstAmt": 5
  },
  rice: { 
    "ItemName": "Rice",
    "ItemCode": 400565,
    "PurRate": 3,
    "DiscAmt": 2,
    "gstPercentage": 20,
    "gstAmt": 8
  },
  milk: { 
    "ItemName": "Milk",
    "ItemCode": 200569,
    "PurRate": 1,
    "DiscAmt": 1,
    "gstPercentage": 50,
    "gstAmt": 2
  },
  'ice cream': { 
    "ItemName": "Ice cream",
    "ItemCode": 800002,
    "PurRate": 16,
    "DiscAmt": 2,
    "gstPercentage": 15,
    "gstAmt": 2
  },
  curd: { 
    "ItemName": "Curd",
    "ItemCode": 100289,
    "PurRate": 9,
    "DiscAmt": 1,
    "gstPercentage": 12,
    "gstAmt": 4

}

var totalAmount = "";
var unitQuantity = "";


function rowappend(tbody) {// this one is appending row{
  
  const markup =

  const itemName = data.map(value => { //using autocomplete to for searching input field
    return value.ItemName;
  });
  $("[name=itemNametd]", tbody).last().autocomplete({
    source: itemName
  });
}
rowappend($('tbody', '#tableInvoice'))


function getValues(row) {
  const search = ($('[name=itemNametd]', row).val()).toString()
  const value = data1[search.toLowerCase()];
  if (value) {
    $(row).find("[name=itemCodetd]").text(value.ItemCode);

  const totalAmount = (parseInt(unitQuantity) * parseInt(purchaseRate));
  
  $(row).find("[name=totalAmttd]").text(totalAmount);
  
}

$(document).on('focusout', (e) => {
  const row = e.target.parentElement.parentElement
  if (e.target.matches('[name=discPercentagetd]')) {
    if ($(row).parent().find('tr').length - $(row).index() === 1) { // only last row
        rowappend(e.target.parentElement.parentElement.parentElement)
    }

  if (e.target.matches('[name=unitQtytd]')) {
    calc(e.target.parentElement.parentElement)
