how to find discount from total sum using javascript

how to find discount from total sum using javascript - javascript

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 :)

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;
if(rowCount < 100){
var row = table.insertRow(rowCount + 1);
var colCount = table.rows[1].cells.length;
for(var i=0; i<colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[1].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) {

break;

Every time, that function is being called, you are changing the innerHTML of of 'demo2' whereas what you need to do is append to it. Use
document.getElementById("demo2").innerHTML += html;
Also, it is not a good idea to use the innerHTML property.It destroys references thus killing eventListeners or similar stuff linked to the object. Hope it helps !

Dynamic HTML form not removing rows - Javascript error

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

For some reason childNodes[0] is text and childNodes[1] is the input you're looking for.

How do I Change id's name or number sequentially after pressing remove row button

My problem before How do I change the select id's name after add table rows? The case is done, but one more problem is change the select id's name or number after remove rows? I have tried using replace and childnodes, but they are still not working.
For example:
I add three rows,
facility1
facility2
facility3
Then remove row for #2, this is exactly what I want
facility1
facility2
but I got,
facility1
facility3
This is the table:
<table id="tableInformation">
<tr>
<td><label>No</label></td>
<td><label>Facility</label></td>
<td><label>Currency</label></td>
<td></td>
</tr>
<tbody>
<tr>
<td><label>1</label></td>
<td><div id="facility">
<select id="facility1" name="facility">
<option value=""></option>
<option value="AL">AL</option>
<option value="BL">BL</option>
<option value="CL">CL</option>
</select>
</td>
<td><div id="currency">
<select id="currency1" name="currency">
<option value=""></option>
<option value="idr">IDR</option>
<option value="usd">USD</option>
<option value="aud">AUD</option>
<option value="jpy">JPY</option>
</select>
</td>
<td><input type="button" id="btnAddRows" value=" + "
onclick=\'addRows()\' />
<input type="button" id="btnRemRows" value=" - "
onclick=\'removeRows(this)\' />
</tr>
</tbody>
</table>
The javascript:
function addRows() {
var table = document.getElementById('tableInformation');
var rowCount = table.rows.length;
var iteration = rowCount -1;
var numbers = iteration +1;
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
// Cell for number
var cell = row.insertCell(0);
var label = document.createElement('label');
label.textContent = numbers;
cell.appendChild(label);
for(var i=1; i<colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML =
table.rows[1].cells[i].innerHTML.replace(/id="(.+)1"/,'id="$1' +
rowCount + '"');
}
}
function removeRows(index) {
var i = index.parentNode.parentNode.rowIndex;
var table = document.getElementById('tableInformation');
var rowCount = table.rows.length;
var iteration = rowCount -1;
/*var numbers = iteration +1;*/
if(iteration == 1) {
alert("Cannot remove");
}else{
table.deleteRow(i);
//alert(iteration);
for(var j=1; j<iteration; j++) {
table.rows[j].cells[0].childNodes[0].id = 'number'+(j-1+1);
table.rows[j].cells[0].childNodes[0].textContent = (j-1+1);
table.rows[j].cells[1].innerHTML.replace(/id="(.+)1"
/,'id="$1' + rowCount + '"');
table.rows[j].cells[2].innerHTML.replace(/id="(.+)1"
/,'id="$1' + rowCount + '"');
table.rows[j].cells[3].innerHTML.replace(/id="(.+)1"
/,'id="$1' + rowCount + '"');
table.rows[j].cells[4].innerHTML.replace(/id="(.+)1"
/,'id="$1' + rowCount + '"');
}
}
}

Use .cloneNode to make copy of the existing element.
Use .remove() to remove the element from the DOM.
Use querySelector to select the element from DOM by specifying selector
On remove() of every element, re-assign id attributes in a loop using setAttribute
var table = document.getElementById('tableInformation');
function addRows() {
var toClone = document.getElementById('toClone').cloneNode(true);
toClone.removeAttribute('id');
var len = table.querySelectorAll('tr').length;
toClone.querySelector('label').textContent = len;
toClone.querySelector('[name="facility"]').setAttribute('id', 'facility' + len);
toClone.querySelector('[name="currency"]').setAttribute('id', 'currency' + len);
table.appendChild(toClone.cloneNode(true));
}
function removeRows(elem) {
var trElems = table.querySelectorAll('tr');
if (trElems.length > 2) {
elem.parentNode.parentNode.remove();
trElems = table.querySelectorAll('tr');
for (var i = 1, len = trElems.length; i < len; i++) {
trElems[i].querySelector('label').textContent = i;
trElems[i].querySelector('[name="facility"]').setAttribute('id', 'facility' + i);
trElems[i].querySelector('[name="currency"]').setAttribute('id', 'currency' + i);
}
} else {
alert('Atleast one row should be there!')
}
}
<table id="tableInformation">

<label>No</label>

Try this:
add one line in your remove function -
table.rows[j].cells[1].childNodes[0].children[0].id = 'facility'+(j-1+1);
as
function removeRows(index) {
var i = index.parentNode.parentNode.rowIndex;
var table = document.getElementById('tableInformation');
var rowCount = table.rows.length;
var iteration = rowCount -1;
/*var numbers = iteration +1;*/
if(iteration == 1) {
alert("Cannot remove");
}else{
table.deleteRow(i);
//alert(iteration);
for(var j=1; j<iteration; j++) {
table.rows[j].cells[0].childNodes[0].id = 'number'+(j-1+1);
table.rows[j].cells[0].childNodes[0].textContent = (j-1+1);
table.rows[j].cells[1].childNodes[0].children[0].id = 'facility'+(j-1+1);
table.rows[j].cells[1].innerHTML.replace(/id="(.+)1"/,'id="$1' + rowCount + '"');
table.rows[j].cells[2].innerHTML.replace(/id="(.+)1"/,'id="$1' + rowCount + '"');
table.rows[j].cells[3].innerHTML.replace(/id="(.+)1"/,'id="$1' + rowCount + '"');
}
}
}
