how can i get sum of one columns rows? [duplicate]

I am trying to add Price from table column to a total.
I am having problem adding values such as 10.00 or 5.99. I am able to calculate prices with int values, but not with values 10.00 or 5.99, etc.
Here is what I have below.
var table = document.getElementById("myTable"),
sumVal = 0;
for (var i = 1; i < table.rows.length; i++) {
sumVal = sumVal + parseF(table.rows[i].cells[2].innerHTML);
}
document.getElementById("val").innerHTML = "SubTotal =" + sumVal;
console.log(sumVal);
<table id="myTable">
<tr>
<th>Item</th>
<th>Price</th>
<th>Remove</th>
</tr>
<tr>
<td>Hoddie</td>
<td class="count-me">15.00</td>
<td><button onClick="myFunction()">Remove</button></td>
</tr>
<tr>
<td>Nike Cap</td>
<td class="count-me">10.99</td>
<td><button onClick="myFunction()">Remove</button></td>
</tr>
</table>
<span id="val"></span>

You have three issues:
You are grabbing the wrong cell index, indices start at 0:
table.rows[i].cells[1]
You need to call the correct parse function:
parseFloat(table.rows[i].cells[1].innerHTML);
You need to format your output:
"SubTotal = $" + sumVal.toFixed(2);
Update: Added functionality for removing rows.
updateSubTotal(); // Initial call
function updateSubTotal() {
var table = document.getElementById("myTable");
let subTotal = Array.from(table.rows).slice(1).reduce((total, row) => {
return total + parseFloat(row.cells[1].innerHTML);
}, 0);
document.getElementById("val").innerHTML = "SubTotal = $" + subTotal.toFixed(2);
}
function onClickRemove(deleteButton) {
let row = deleteButton.parentElement.parentElement;
row.parentNode.removeChild(row);
updateSubTotal(); // Call after delete
}
#myTable td {
padding: 0.25em;
}
#val {
display: block;
margin-top: 0.5em;
}
<table id="myTable">
<tr>
<th>Item</th>
<th>Price</th>
<th>Remove</th>
</tr>
<tr>
<td>Hoodie</td>
<td class="count-me">15.00</td>
<td><button onClick="onClickRemove(this)">Remove</button></td>
</tr>
<tr>
<td>Nike Cap</td>
<td class="count-me">10.99</td>
<td><button onClick="onClickRemove(this)">Remove</button></td>
</tr>
</table>
<span id="val"></span>

You are accessing the incorrect array element and also need to use parseFloat
The cells array is zero-based so you need to use cells[1] to access the second column:
var table = document.getElementById("myTable"),
sumVal = 0;
for (var i = 1; i < table.rows.length; i++) {
sumVal = sumVal + parseFloat(table.rows[i].cells[1].innerHTML);
}
document.getElementById("val").innerHTML = "SubTotal =" + sumVal;
console.log(sumVal);
<table id="myTable">
<tr>
<th>Item</th>
<th>Price</th>
<th>Remove</th>
</tr>
<tr>
<td>Hoddie</td>
<td class="count-me">15.00</td>
<td><button onClick="myFunction()">Remove</button></td>
</tr>
<tr>
<td>Nike Cap</td>
<td class="count-me">10.99</td>
<td><button onClick="myFunction()">Remove</button></td>
</tr>
</table>
<span id="val"></span>

updateSubTotal(); // Initial call
function updateSubTotal() {
var table = document.getElementById("myTable");
let subTotal = Array.from(table.rows).slice(1).reduce((total, row) => {
return total + parseFloat(row.cells[1].innerHTML);
}, 0);
let subTotal2 = Array.from(table.rows).slice(1).reduce((total, row) => {
return total + parseFloat(row.cells[2].innerHTML);
}, 0);
document.getElementById("val").innerHTML = "SubTotal = $" + subTotal.toFixed(2);
document.getElementById("val1").innerHTML = subTotal2.toFixed(2);
}
function onClickRemove(deleteButton) {
let row = deleteButton.parentElement.parentElement;
row.parentNode.removeChild(row);
updateSubTotal(); // Call after delete
}
#myTable td {
padding: 0.25em;
}
#val {
display: block;
margin-top: 0.5em;
}
<table id="myTable">
<tr>
<th>Item</th>
<th>Price</th>
<th>M2</th>
<th>Remove</th>
</tr>
<tr>
<td>Hoodie</td>
<td class="count-me">15.00</td>
<td class="count-me">34.00</th>
<td><button onClick="onClickRemove(this)">Remove</button></td>
</tr>
<tr>
<td>Nike Cap</td>
<td class="count-me">10.99</td>
<td class="count-me">22.34</th>

var cell = document.getElementsByClassName("count-me");
var val = 0;
var i = 0;
while (cell[i] != undefined) {
val += parseFloat(cell[i].innerHTML);
i++;

I have two html table which make sum each it row and last row show sum.
Now I what calculate rate from sum result from this html table
I want show result like this
rate1 = (box1-total-1) * 100 / box2-total-1
rate2 = (box1-total-2) * 100 / box2-total-2
<div class="rate1"></div>
<div class="rate2"></div>

You are using incorrect class names. In line - $('.box1 .box_price-1') there is a class with name box_price1 not box_price-1.
let box1Sum1 = 0;
$('.box1 .box_price1').each(function() {
box1Sum1 += parseInt($(this).text());
});
$('.box1 .box_sum-1').text(box1Sum1);
let box1Sum2 = 0;
$('.box1 .box_price2').each(function() {
box1Sum2 += parseInt($(this).text());
})
$('.box1 .box_sum-2').text(box1Sum2);
let box2Sum1 = 0;
$('.box2 .box_price1').each(function() {
box2Sum1 += parseInt($(this).text());
});
$('.box2 .box_sum-1').text(box2Sum1);
let box2Sum2 = 0;
$('.box2 .box_price2').each(function() {
box2Sum2 += parseInt($(this).text());
});
$('.box2 .box_sum-2').text(box2Sum2);
const rate1 = box1Sum1 * 100 / box2Sum1;
const rate2 = box1Sum2 * 100 / box2Sum2;
console.log(rate1, rate2);
$('div.rate1').text('Rate 1: ' + rate1 );

While loop inside a for loop concatening

when I execute this code it spits out a new row inside the table but it includes the previous iteration along with the newest one. I want all "As" to be in the first row in the main table. And then I want all "Bs" to be in the second , etc, etc. Then for A0, A1, and A2, I want them to be in their own table within the first row, same for B0, B1 in the second row, etc, etc

Initialize the text variable to the empty string inside the first loop instead:
for (var i = 0; i < array.length; i++) {
let text = '';
But note that you can make your code more functional, shorter, and easier to read by using array methods like .map and forEach rather than using for, while, and manual iteration (better not to have to keep track of indicies):
array.forEach((subArr, i) => {
const text = subArr.map(item => "<tr><td>" + item + "</td></tr>");
document.getElementById(i).innerHTML = text.join('');
});
var array = [
["A0---", "A1----", "A2---"],
["B0----", "B1---"],
["C0---", "C1---"],
["D0---", "D1---"]
];
array.forEach((subArr, i) => {
const text = subArr.map(item => "<tr><td>" + item + "</td></tr>");
document.getElementById(i).innerHTML = text.join('');
});

Declare this variable var text = ""; inside of the for-loop

How To Sum All Table Rows td (TotalPrice) using td id Jquery

I am adding values to table like:
Item,Quantity,Price,TotalPrice
Now there are multiple rows: How can i sum TotalPrice of all to get GrandTotal using Jquery.
Code:
$("#Product").append(" <tr><td id='clientname'>" +ClientName+ "</td> <td id='item'>"+ItemName+"</td> <td id='quantity'>"+Quantity+"</td> <td id='price'>"+Price+"</td> <td id='totalprice'>"+TotalPrice+"</td> <td> <a onClick='deleteRow(this);'>Delete</a> </td> </tr>");
Its possible when i insert new row data its show grand total in textbox/label,Like:
function TotalPriceCalc()
{
var lblTotalPrice = document.getElementById('lblTotalPrice');
lblTotalPrice.value = sum;
}

Here's an example that will sum whatever column index you provide.
$(function() {
$("#subtotal").html(sumColumn(4));
$("#total").html(sumColumn(5));
});
function sumColumn(index) {
var total = 0;
$("td:nth-child(" + index + ")").each(function() {
total += parseInt($(this).text(), 10) || 0;
});
return total;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table style="border-spacing: 10px;">
<tr>
<td>ClientName</td>
<td>ItemName</td>
<td>Quantity</td>
<td>12</td>
<td>34</td>
</tr>
<tr>
<td>ClientName</td>
<td>ItemName</td>
<td>Quantity</td>
<td>56</td>
<td>78</td>
</tr>
<tr>
<td>ClientName</td>
<td>ItemName</td>
<td>Quantity</td>
<td>90</td>
<td>12</td>
</tr>
<tr>
<td colspan="3">Totals</td>
<td id="subtotal"></td>
<td id="total"></td>
</tr>
</table>

After you use class= instead of id= .Cause ID MUST be unique. you need to loop through each row and find totalPrice
$(document).ready(function(){
var TotalValue = 0;
$("#Product tr").each(function(){
TotalValue += parseFloat($(this).find('.totalprice').text());
});
alert(TotalValue);
});
While you tagged Jquery .. This is a Jquery solution so please be sure to include Jquery

You should use classes, not IDs, to name repeated elements. So it should be:
...<td class="totalprice">'+TotalPrice+'</td>...
Then you can do
function TotalPriceCalc() {
var total = 0;
$(".totalprice").each(function() {
total += parseFloat($(this).text());
});
$("#lblTotalPrice").val(total);
}

Have look, this is our table
<table class="table table-bordered">
<thead>
<tr>
<th>1</th>
<th>Price</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td id="loop">50</td>
</tr>
<tr>
<td>1</td>
<td id="loop">60</td>
</tr>
<tr>
<td>1</td>
<td id="loop">70</td>
</tr>
</tbody>
<tbody>
<tr>
<td class="text-right">Total</td>
<td></td>
</tr>
</tbody>
And this is loop to have sum of price
$(function() {
var TotalValue = 0;
$("tr #loop").each(function(index,value){
currentRow = parseFloat($(this).text());
TotalValue += currentRow
});
console.log(TotalValue);
});

how to get value from table td using javascript

i want to get the value of Save using jquery through input on keyup function.. i am matching value with Buy..means if value matched with the value(range) of Buy..then get the value of Save..
for example if i entered 3 in textfield then it gets value from Save 45%..and if i entered 8 then result should be 51%..entered 15 result 56% and so on.
here is image link for better understanding.

here is input field
<label for="">Enter Quantity</label>
<input type="text" name="qty" id="qty"></input>
i have tried some code but still no luck..

Try adding data attributes holding the price limits on each td contains the price limits:
$(document).on('input', '#qty', function() {
var that = $(this);
var val = that.val();
if (!isNaN(val)) {
$('.limitTd').each(function() {
var thatTd = $(this);
//var from = parseInt(thatTd.attr('data-from'));
//var to = parseInt(thatTd.attr('data-to'));
var lim = thatTd.html().toString().split('-');
if (lim.indexOf('-') != -1) {
var from = parseInt(lim[0]);
var to = parseInt(lim[1]);
} else {
var from = parseInt(lim.toString().replace('+'));
var to = 9999999;
}
console.log(lim);
if ((val >= from) && (val <= to)) {
var save = thatTd.closest('tr').find('.save_red').html();
$('#saveDiv').html(save);
}
});
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table class="attribute_table">
<tbody>
<tr>
<th>Buy</th>
<th>Unit</th>
<th>Price/unit</th>
<th class="save_red">Save</th>
</tr>
<tr>
<td class="limitTd" data-from="3" data-to="5">3-5</td>
<td>Pairs</td>
<td class="td_price"><span class="price">$4.99</span></td>
<td class="save_red">45%</td>
</tr>
<tr>
<td class="limitTd" data-from="6" data-to="11">6-11</td>
<td>Pairs</td>
<td class="td_price"><span class="price">$4.49</span></td>
<td class="save_red">51%</td>
</tr>
<tr>
<td class="limitTd" data-from="12" data-to="23">12-23</td>
<td>Pairs</td>
<td class="td_price"><span class="price">$3.99</span></td>
<td class="save_red">56%</td>
</tr>
<tr>
<td class="limitTd" data-from="24" data-to="99999">24+</td>
<td>Pairs</td>
<td class="td_price"><span class="price">$3.90</span></td>
<td class="save_red">57%</td>
</tr>
</tbody>
</table>
<label for="">Enter Quantity</label>
<input type="text" name="qty" id="qty"></input>
<div id="saveDiv" style="border:1px solid #d8d8d8;width: 100px;height:50px;float:left"></div>
ALTERNATIVE (No data attributes)
If you don't want to use data attributes, you must manipulate the html to extract the price limits.
For example:
var lim = $('.limitTd').html().split('-');
var from = lim[0];
var to = lim[1];

var mapUnits = [];
$('tr').each(function(i) {
if (!$(this).find("td:nth-child(1)")[0]) {
return;
}
var units = $(this).find("td:nth-child(1)")[0].innerText;
var saveperc = $(this).find("td:nth-child(4)")[0].innerText;
var splits = units.split('-');
var range1 = parseInt(splits[0]);
var range2 = parseInt(splits[1] ? splits[1] : 10000);
mapUnits.push({
range1: range1,
range2: range2,
saveperc: saveperc
})
});
$("#qty").keyup(function() {
$('#saveperc').html('');
var val = $("#qty").val();
for (var m in mapUnits) {
if (mapUnits[m].range1 <= val && mapUnits[m].range2 >= val) {
$('#saveperc').html(mapUnits[m].saveperc);
}
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="attribute_table">
<tbody>
<tr>
<th>Buy</th>
<th>Unit</th>
<th>Price/unit</th>
<th class="save_red">Save</th>
</tr>
<tr>
<td>3-5</td>
<td>Pairs</td>
<td class="td_price"><span class="price">$4.99</span>
</td>
<td class="save_red">45%</td>
</tr>
<tr>
<td>6-11</td>
<td>Pairs</td>
<td class="td_price"><span class="price">$4.49</span>
</td>
<td class="save_red">51%</td>
</tr>
<tr>
<td>12-23</td>
<td>Pairs</td>
<td class="td_price"><span class="price">$3.99</span>
</td>
<td class="save_red">56%</td>
</tr>
<tr>
<td>24+</td>
<td>Pairs</td>
<td class="td_price"><span class="price">$3.90</span>
</td>
<td class="save_red">57%</td>
</tr>
</tbody>
</table>
<label for="">Enter Quantity</label>
<input type="number" name="qty" id="qty"></input>
<div id='saveperc'></div>
If you cant change the Html, do like this.

Try with -
$('#qty').on('keyup', function() {
var trs = $('table.attribute_table').find('tr:not(:first)');
var val = trs.find('td:first').text();
values = val.split('-');
if ($(this).val() >= values[0] && $(this).val() <= values[1]) {
var dis = trs.find('td.save_red').text();
alert(dis);
}
})
