I want to create a quality control table using javascript, but when I add more than two variables everything stops working, even though I need 20 sequences in the table.
For now, I'm trying with javascript, maybe you can help with other alternatives like using JQuery
JavaScript I use:
function testfunction(){
var arr = document.getElementsByName('hp');
var arr2 = document.getElementsByName('sd-sum');
var v1 = document.getElementById("v_1").value;
var v2 = document.getElementById("v_2").value;
/**
* I want to add more
* var v3 = document.getElementById("v_3").value;
* var v4 = document.getElementById("v_4").value;
* ............
* up to 20
*/
var tot=0;
for(var i=0;i<arr.length;i++){
if(parseInt(arr[i].value))
tot += parseInt(arr[i].value);
}
var tot_sd=0;
for(var i=0;i<arr2.length;i++){
if(parseInt(arr2[i].value))
tot_sd += parseInt(arr2[i].value);
}
tot_ = document.getElementById('tot_result');
tot_sdsum = document.getElementById('tot_sd');
mean_ = document.getElementById('mean');
sd_ = document.getElementById('SD');
cv_ = document.getElementById('CV');
mean_all = tot / 20;
x1_v = mean_all - v1;
x2_v = mean_all - v2;
y1_x = Math.pow(x1_v,2).toFixed(2);
y2_x = Math.pow(x2_v,2).toFixed(2);
/**
* I want to add more
* x3_v = mean_all - v3;
* x4_v = mean_all - v4;
* ............
* up to 20
*/
tot_.innerHTML = tot;
mean_.value = mean_all;
document.getElementById("x_1").value = x1_v;
document.getElementById("x_2").value = x2_v;
document.getElementById("y_1").value = y1_x;
document.getElementById("y_2").value = y2_x;
/**
* I want to add more
* document.getElementById("x_3").value = x3_v;
* document.getElementById("x_4").value = x4_v;
* ............
* up to 20
*/
tot_sdsum.innerHTML = tot_sd;
sd_cal = (tot_sd / 19).toFixed(2);
sd_.value = sd_cal ;
cv_.value =(sd_cal / mean_all * 100).toFixed(2);
};
document.addEventListener("DOMContentLoaded", function(event) {
testfunction();
});
and HTML
<table class="table">

Any help would be appreciated.
Instead of storing values in individual variables you can use array.
I have created a JSFiddle for your reference : https://jsfiddle.net/dt1m9oc8/19/

How can I make sure that the second part of function runs, calculating the columns and showing the result at the end of each row?
function sum_row_qty(el, poOrigin) {
let rowTotal = 0
if (el) {
let parent = el.closest("tr")
parent.querySelectorAll('.size_qty').forEach(function(e) {
rowTotal += parseFloat(e.value);
})
if (rowTotal) {
parent.querySelector('.qty').value = rowTotal;
}
} else {
document.querySelectorAll("#tableRows > tr > td:first-child input").forEach(sum_row_qty);
}
}
<table class="table table-hover table-vcenter" id="dtable">

Here is the answer proposed by a gentleman on another platform:
function sumInputs(row) {
const inputsArr = [...row.querySelectorAll('.size_qty')];
return inputsArr.reduce((total, {
value
}) => total += parseFloat(value), 0);
}
function sum_row_qty(el) {
if (el) {
const currentRow = el.closest("tr");
currentRow.querySelector('.qty').value = sumInputs(currentRow);
}
}
tableRows.querySelectorAll('tr').forEach(row => {
row.querySelector('.qty').value = sumInputs(row);
});
<table class="table table-hover table-vcenter" id="dtable">

I have already tried
function Next(e) {
if (e.which === 13) {
var Element = $(this).closest('tr').next().find('.input');
Element.focus();
} else {
$("#Msg").html('another Pressed');
}
}
You can use nextElementSibling.focus():
function Next(e) {
if (e.which === 13) {
e.target.nextElementSibling.focus();
}
else {
$("#Msg").html('another Pressed');
}
}
Hey #NibrasAffairs use :first selector.
$('.input').keydown(function (e) {
if (e.which === 13) {
$(this).closest('tr').next().find('input[type=text]:first').focus();
}
});

I have a Client Data Entry Form, it is quite large but works great. Except for one problem I added a script to calculate the total of up to 5 fields Max. The script works, it does the calculation and the total appears. When I submit the form the data isn't being submitted to mysql.
Here is the script:
<script>
var calculateForm = function () {
document.getElementById("total_paid").value = (Number(document.getElementById("amount1").value) + Number(document.getElementById("amount2").value) + Number(document.getElementById("amount3").value) + Number(document.getElementById("amount4").value) + Number(document.getElementById("amount5").value));
};
</script>
Here is part of the form:
<div class="rent_own_info">

Thanx ZZ
I am stuck at jQuery Problem. i think i am going wrong in this code. please help.
I'm trying to get value of input box by clicking update button. but everytime i get only first number.
I want text value according update button.
$(".update").click(function(){
qty = $(".qty").val();
alert(qty);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td><input type="text" name="qty" value="5" class="qty" id="qty"/></td>
<td><button class="update">↻</button></td>

<td><button class="update">↻</button></td>

You have to "link" your update button whith the input ".qty" you want to associate to
$(".update").click(function(){
qty = $(this).closest("tr").find(".qty").val();
alert(qty);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td><input type="text" name="qty" value="5" class="qty" id="qty"/></td>
<td><button class="update">↻</button></td>
</tr>
<tr>
<td><input type="text" name="qty" value="20" class="qty" id="qty"/></td>
<td><button class="update">↻</button></td>
</tr>
<tr>
<td><input type="text" name="qty" value="30" class="qty" id="qty"/></td>
<td><button class="update">↻</button></td>
</tr>
<tr>
<td><input type="text" name="qty" value="50" class="qty" id="qty"/></td>
<td><button class="update">↻</button></td>
</tr>
<tr>
<td><input type="text" name="qty" value="45" class="qty" id="qty"/></td>
<td><button class="update">↻</button></td>
</tr>
<tr>
<td><input type="text" name="qty" value="15" class="qty" id="qty"/></td>
<td><button class="update">↻</button></td>
</tr>
<tr>
<td><input type="text" name="qty" value="70" class="qty" id="qty"/></td>
<td><button class="update">↻</button></td>
</tr>
</table>
change the qty variable as below:
var thisObj = $(this);
qty = $(thisObj).parent().parent().find("input").val();
$(".update").click(function(){
qty = $(".qty").val();
alert(qty);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I'm looking to Group my Table data and Sum by the group (like sum price by product). In a second Table.
I want group or filter by Item column, and sum the result of the Price column.
So Oranges (having two lines) should be one line with Sum price.
See this example below:
<table width="400" border="1">
<tr>
<td>Item</td>
<td>Location</td>
<td>Quantity</td>
<td>Price</td>
</tr>
<tr>
<td><input name="item" type="text" id="item" value="Orange" /></td>
<td><input name="location" type="text" id="location" value="Tree" /></td>
<td><input name="quantity" type="text" id="quantity" value="3" /></td>
<td><input name="price" type="text" id="price" value="3.00" /></td>
</tr>
<tr>
<td><input name="item" type="text" id="item2" value="Apple" /></td>
<td><input name="location" type="text" id="location" value="Tree" /></td>
<td><input name="quantity" type="text" id="quantity" value="1" /></td>
<td><input name="price" type="text" id="price" value="1.00" /></td>
</tr>
<tr>
<td><input name="item" type="text" id="item" value="Orange" /></td>
<td><input name="location" type="text" id="location" value="Tree" /></td>
<td><input name="quantity" type="text" id="quantity" value="4" /></td>
<td><input name="price" type="text" id="price" value="4.00" /></td>
</tr>
<tr>
<td><input name="item" type="text" id="item" value="Grapes" /></td>
<td><input name="location" type="text" id="location" value="Vine" /></td>
<td><input name="quantity" type="text" id="quantity" value="10" /></td>
<td><input name="price" type="text" id="price" value="10.00" /></td>
</tr>
</table>
<p> </p>
<table width="400" border="1">
<tr>
<td>Orange</td>
<td>7</td>
<td>7.00</td>
</tr>
<tr>
<td>Apple</td>
<td>1</td>
<td>1.00</td>
</tr>
<tr>
<td>Grapes</td>
<td>10</td>
<td>10.00</td>
</tr>
</table>
First change id "price" to class, then
$(document).ready(function(){
var sum = 0;
$('.price').each(function(){
sum += $(this).val();
});
alert("The sum is " + sum);
});
You can modify above code to get sum in button click event too.
