I'm nearing the end of this script and I've noticed an error.
It's possible to add rows to the table, however when I try to remove them it doesn't seem to work. I'm guessing the error is somewhere in my JS. It was working before and then stopped working all of a sudden! Can someone please shed some light on it?
Thanks,
Snelly

Here are the code to work:
function deleteRow(tableID) {
debugger;
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for (var i = 0; i < rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0].nextElementSibling;
if (chkbox != null && chkbox.checked) {
if (rowCount <= 1) { // limit the user from removing all the fields
alert("Cannot Remove all of the items!.");
break;
}
table.deleteRow(i);
rowCount--;
i--;
}
}
}
For some reason childNodes[0] is text and childNodes[1] is the input you're looking for.

I have a table that a user can dynamically add a row as needed. And as you can see underneath the table that is a sum of the last column's value which is dynamically added. I need to add two text boxes above the sum from that one textbox(name as discount) take input(as a number) from user and the second textbox(name as finalsum) display the output as the value(finalsum=sum-discount). and if the user does not give any input value then the discount should be initially zero. and the finalsum should be equal to sum
if you want more info let me know thank you! Any help will be greatly appreciated :)

Hi am not much expertise in javascript, In my code I have Add-Items & Delete-Items button which is working fine.First row works fine for total calculation function but rest of rows not working because of that Am not able to assign different names and ids for created row. How I can reuse javascript. Also please let me know how to receive data on submit using POST method or this code and how to find total amount of all rows I inserted at the bottom of table.
Thanks in Advance

Here's my script
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
if(rowCount < 100){
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for(var i=0; i<colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[0].cells[i].innerHTML;
}
}else{
alert("Maximum items is 100.");
}
}
function deleteRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for(var i=0; i<rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
if(null != chkbox && true == chkbox.checked) {
if(rowCount <= 1) {
alert("Cannot Remove all the Items.");
break;
}
table.deleteRow(i);
rowCount--;
i--;
}
}
}
Instead to use IDs you may change them to class names like in:
<input type="text" required="required" name="Qty[]" class="qty" value="" oninput="func(this)">
Because you are using inline events you can:
use input event because the DOM input event is fired synchronously when the value of an <input>, <select>, or <textarea> element is changed.
this as parameter to the inline function: it will be the current element
Hence, change your func to:
function func(ele) {
var parentRow = ele.parentNode.parentNode;
var w = parentRow.querySelector('input.qty').value;
var x = parentRow.querySelector('input.price').value;
var z = parentRow.querySelector('input.total');
z.value = Number(w)*Number(x);
}
The this parameter now is the ele, current element. You can now get the parent row and using the classes and querySelector you can find all elements.
The snippet:
function updateGrandTotal() {
var gt = document.querySelector('input.grantotal');
gt.value = 0;
document.querySelectorAll('input.total').forEach(function(ele, idx) {
gt.value = +gt.value + +ele.value;
});
}
function func(ele) {
var parentRow = ele.parentNode.parentNode;
var w = parentRow.querySelector('input.qty').value;
var x = parentRow.querySelector('input.price').value;
var z = parentRow.querySelector('input.total');
z.value = Number(w)*Number(x);
updateGrandTotal();
}
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length -1;

for(var i=0; i<colCount; i++) {

newcell.innerHTML = table.rows[1].cells[i].innerHTML;

I am using this code this is html form where i need the javascript onblur calculation of qty * rate = amount
<div>
<p>
<input type="button" value="Add Product" onClick="addRow('dataTable')" />
<input type="button" value="Remove Product" onClick="deleteRow('dataTable')" />
</p>
<table style="width: 100%;" id="dataTable" class="responstable" border="1">
<tbody>
<tr>
<p>
<td><input type="checkbox" required="required" name="chk[]" checked="checked" /></td>
<td><input type="text" name="prod" maxlength="100" placeholder="Product *" required></td>
<td>
<input type="number" name="qty[]]" maxlength="10" placeholder="QUANTITY *" required>
</td>
<td>
<input type="number" step="0.01" name="rate[]" maxlength="10" placeholder="RATE *" required>
</td>
<td>
<input type="number" step="0.01" name="amt[]" placeholder="AMOUNT *" required>
</td>
</p>
</tr>
</tbody>
</table>
</div>
And this is Javascript code i am using for add input fields
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
if(rowCount < 25){ // limit the user from creating fields more than your limits
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for(var i=0; i<colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[0].cells[i].innerHTML;
}
}else{
alert("Maximum Limit is 25.");
}
}
function deleteRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for(var i=0; i<rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
if(null != chkbox && true == chkbox.checked) {
if(rowCount <= 1) { // limit the user from removing all the fields
alert("Cannot Remove all the Products.");
break;
}
table.deleteRow(i);
rowCount--;
i--;
}
}
}
I need also auto calculation of total amount.
I know it is done by using input field id but here the problem is i don't know how to add different input field ID when i click add product here the same id comes on next input field so what is the best solution for this.
Try this fiddle for dynamic added elements jsfiddle.net/bharatsing/yv9op3ck/2/
HTML:
<div>
<p>
<input type="button" value="Add Product" id="btnAddProduct" />
<input type="button" value="Remove Product" id="btnRemoveProduct" />
<label>Total Amount:</label><label id="lblTotal">0</label>
</p>
<table style="width: 100%;" id="dataTable" class="responstable" border="1">
<tbody>
<tr>
<p>
<td><input type="checkbox" required="required" name="chk[]" checked="checked" /></td>
<td><input type="text" name="prod" maxlength="100" placeholder="Product *" required></td>
<td>
<input type="number" name="qty[]" maxlength="10" placeholder="QUANTITY *" required>
</td>
<td>
<input type="number" step="0.01" name="rate[]" maxlength="10" placeholder="RATE *" required>
</td>
<td>
<input type="number" step="0.01" name="amt[]" placeholder="AMOUNT *" required>
</td>
</p>
</tr>
</tbody>
</table>
</div>
Javascript/jQuery:
$("#btnAddProduct").click(function(){
addRow('dataTable');
});
$("#btnRemoveProduct").click(function(){
deleteRow('dataTable');
});
function CalculateAll(){
$('input[name="rate[]"]').each(function(){
CalculateAmount(this);
});
var total=0;
$('input[name="amt[]"]').each(function(){
total+= parseFloat($(this).val());
});
$("#lblTotal").html(total);
}
$(document).on("blur",'input[name="qty[]"]',function(){
CalculateAmount(this);
});
$(document).on("blur",'input[name="rate[]"]',function(){
CalculateAmount(this);
});
var totalAll=0;
function CalculateAmount(ctl){
var tr=$(ctl).parents("tr:eq(0)");
var qty=parseFloat($(tr).find('input[name="qty[]"]').val());
var rate=parseFloat($(tr).find('input[name="rate[]"]').val());
var amount=qty*rate;
$(tr).find('input[name="amt[]"]').val(amount);
if(!isNaN(amount)){
totalAll= totalAll + amount;
$("#lblTotal").html(totalAll);
}
}
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
if(rowCount < 25){ // limit the user from creating fields more than your limits

}
}else{
alert("Maximum Limit is 25.");
}
}
function deleteRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for(var i=0; i<rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
if(null != chkbox && true == chkbox.checked) {
if(rowCount <= 1) { // limit the user from removing all the fields

break;
}
table.deleteRow(i);
rowCount--;

}
}
CalculateAll();
}
Since in your code you are only using JavaScript. Here is an attempt with JavaScript. You need not to have ID attribute only to calculate the total amount , you can give your amount element a class amount and use it to get sum on all the elements having this class.
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
if(rowCount < 25){ // limit the user from creating fields more than your limits
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for(var i=0; i<colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[0].cells[i].innerHTML;
}
}else{
alert("Maximum Limit is 25.");
}
}
function deleteRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for(var i=0; i<rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
if(null != chkbox && true == chkbox.checked) {
if(rowCount <= 1) { // limit the user from removing all the fields
alert("Cannot Remove all the Products.");
break;
}
table.deleteRow(i);
rowCount--;
i--;
}
}
}
function amount(event)
{
var rate =parseInt(event.target.value, 10);
var qty = parseInt(event.target.parentElement.previousElementSibling.querySelector("input").value, 10);
event.target.parentElement.nextElementSibling.querySelector("input").value = rate * qty;
}
function calculate()
{
var total = 0;
document.querySelectorAll(".amount").forEach(function(elem)
{
total = total + parseInt(elem.value,10);
});
alert(total);
}

I'm trying to add dynamic row of table in my code. And when I click on the add button it displays the incorrect row. It suppose to display the checkbox, dropdown and input text row instead of the header row. Below are the javascript and html code together with the incorrect output. Do I have to change the javascript code? I've also tried looking for the answer inside the web but I found nothing. Please help me thanks.
Javascript code:
<script>
function addRow(tableID){
var table=document.getElementById(tableID);
var rowCount=table.rows.length;
var row=table.insertRow(rowCount);
var colCount=table.rows[0].cells.length;
for(var i=0;i<colCount;i++){
var newcell=row.insertCell(i);
newcell.innerHTML=table.rows[0].cells[i].innerHTML;
switch(newcell.childNodes[0].type){
case"select-one":newcell.childNodes[0].selectedIndex=0;
break;
case"checkbox":newcell.childNodes[0].checked=false;
break;
case"text":newcell.childNodes[0].value="";
break;}}}
function deleteRow(tableID){
try{
var table=document.getElementById(tableID);
var rowCount=table.rows.length;
for(var i=0;i<rowCount;i++){
var row=table.rows[i];
var chkbox=row.cells[0].childNodes[0];
if(null!=chkbox&&true==chkbox.checked){
if(rowCount<=1){alert("Cannot delete all the rows.");
break;}
table.deleteRow(i);
rowCount--;
i--;}}}
catch(e){alert(e);}}
</script>
HTML Code :
<input type="button" value="Add More" onClick="addRow('dataTable')">
<input type="button" value="Delete" onClick="deleteRow('dataTable')">
<table id="dataTable" border="1">
<tr>
<th>✓</th>
<th> Relationship </th>
<th> Name </th>
<th> Occupation </th>
<th> Phone Number </th>
</tr>
<tr>
<td><input type="checkbox" name="chk"></td>
<td>
<select name="fam_relationship[]" id="fam_relationship">
<option value="">Select one</option>
<option value="Spouse">Spouse</option>
<option value="Father">Father</option>
<option value="Mother">Mother</option>
</select>
</td>
<td><input type="text" name="fam_name[]" id="fam_name"> </td>
<td><input type="text" name="fam_occupation[]" id="fam_occupation"></td>
