Why does the page reload when the button is pressed - javascript

I have a input text field with datalist. The Datalist data comes from a database. The input field is generated dynamically with javascript and if i transfer the value of the input field into the textarea field with the button, the page is reloading and I don't know why.
If someone could help me, that would pretty nice :)
This is the snippet of the button in line 10:
<button class="button3" style="width:185px;" onclick="artikeleinfuegen()">Artikel übernehmen</button>
And this is the function:
function artikeleinfuegen() {
var x = document.getElementById("artikelsuche").value;
document.getElementById("artikelbeschreibung[]").innerHTML = x;
}
This is the whole script.
var steuer = '19,00';
function O(id) {
return document.getElementById(id)
}
function insertPos() {
pos = '<table><tr>';
pos += '<td valign=top style="width:100px;"><input type=text name="anz[]" value="1" size=4 onKeyUp="calculate()" /></td>';
pos += '<td valign=top style="width:100px;"><select name="einheit[]"><option value="Lfm.">Lfm.</option><option value="Pal.">Pal.</option><option value="pschl.">pschl.</option><option value="Pkg.">Pkg.</option><option value="Std.">Std.</option><option value="Stk.">Stk.</option> size=4 onKeyUp="calculate()" /></td>';
pos += '<td valign=top><input type="text" list="artikelliste" name="artikelsuche" id="artikelsuche" autocomplete="off" placeholder="Artikelsuche" style="width:700px;"><button class="button3" style="width:185px;" onclick="artikeleinfuegen()">Artikel übernehmen</button><br><textarea style="width:900px;" rows=7 name=dsc[] id=artikelbeschreibung[] onKeyUp="typeAhead(event, this)"></textarea></td>';

pos += '<td valign=top><input style="color:red;" type=button name="del[]" value=" X " onclick="deletePos(this);"/></td>';
pos += '</tr></table>';
obj = document.createElement("DIV");
obj.innerHTML = pos;
O("docpos").appendChild(obj);
a_anz = document.getElementsByName("anz[]");
a_anz[a_anz.length - 1].focus()
}
function Rabatt() {
return '<div class="column1">Gesamtrabatt €<input type=text name="geserab" value="0" size=4 onKeyUp="calculate()"></div><div class="column1">Gesamtrabatt %<input type=text name="gesprab" value="1" size=4 onKeyUp="calculate()"></div>';
}
function deletePos(obj) {

calculate()
}
function calculate() {

if (!(isNaN(menge) || isNaN(preis))) sum = sum + (((menge * preis) - (menge * postenrabatteuro)) * postenrabattprozent)
}
gesamtrabatteuro = parseFloat(b_geserab[0].value.replace(/,/, "."));
gesamtrabattprozent = parseFloat(b_gesprab[0].value.replace(/,/, "."));

gr = (sum * gesamtrabattprozent - gesamtrabatteuro) - sum;
nettoabzug = sum + gr;
total = sum + st;
O("netto").value = sum.toFixed(2).toString().replace(/\./, ",") + " €";
O("gr").value = gr.toFixed(2).toString().replace(/\./, ",") + " €";

How to change value inside input box that generated by jQuery?

please help me resolved this problem, I have an input value (weight) that generated by jQuery, I know it won't change it's value because of looping in my code, but is there another way to do this ?
The goal is I want to autogenerate the weight input value, but I can change it too.
if the snippet don't work, here's the link :
https://jsfiddle.net/s3grkqxm/
Thank you for your help.
var numRows = 2, ti = 5;

var grandtotal = 0;
var grandtotalbtg = 0;
$('#kas_table').find('tr').each(function() {
var berat = $(this).find('input.berat').val();
var qty = $(this).find('input.qty').val();
var subtotal = (berat * qty);
let berat_max = $(this).find('option:selected').data('berat');
$(this).find('input.subtotal').val(Math.round(subtotal * 100) / 100);
$(this).find('input.berat').val(berat_max).text();
});
}
$(function() {

</div>
the reason when you change Weight it back to the original value is because you refresh the whole table including the drop-down that's why it set back the value which must be set after the dropdown change.$('div.table-responsive').on("keyup change blur", recalc); due this.
you just need to separate each element change event to get the proper results.
I set the value in Weight on the change dropdown by adding this
$(document).on('change', 'select', function() {
$('#kas_table').find('tr').each(function() {
let berat_max = $(this).find('option:selected').data('berat');
$(this).find('input.berat').val(berat_max).text();
});
});
and separately call qty and weight using this
$('.qty').on("keyup change blur", recalc);
$('.berat').on("keyup change blur", recalc);
finally here is your updated code working as expected hope it will helpful for you.

How to fix duplicate entries in number field in javascript

I have nine number fields to calculate. I need to check for duplicate entries in these 9 number fields and if found duplicate values, change the background color of the screen to 'red'. I'm not able to find solution for the mentioned.
I have created a table with 9 nine number fields to input the numbers and calculate the sum.
I searched for code to check for duplicate values in number fields, but found code to check for duplicate values in text fields.
<html>
<head>
<script>
function Sum() {
alert("hi");
var num1 = Number(document.getElementById("qty1").value);
var num2 = Number(document.getElementById("qty2").value);
var num3 = Number(document.getElementById("qty3").value);
var num4 = Number(document.getElementById("qty4").value);
var num5 = Number(document.getElementById("qty5").value);
var num6 = Number(document.getElementById("qty6").value);
var num7 = Number(document.getElementById("qty7").value);
var num8 = Number(document.getElementById("qty8").value);
var num9 = Number(document.getElementById("qty9").value);
var sum=num1+num2+num3+num4+num5+num6+num7+num8+num9
document.getElementById("answer").value = sum;
}
</script>
<style>
table>tbody>tr:nth-child(odd){
background-color: blue;
}
table>tbody>tr:nth-child(even){
background-color: green;
}
table>tbody>tr:nth-child(odd)>td:nth-child(odd){

}
table>tbody>tr:nth-child(even)>td:nth-child(even){

<div align="center">
<input type="button" onclick="Sum()" name="Sum" value="Sum" id="sum">
<input id="answer">
</div>
</body>
</html>
The above code generates 9 input number fields in table format to enter numbers and calculate the sum
Add your numbers to an array and loop through. One possible example, see https://codepen.io/anon/pen/yZaBrb:
var a = new Array(1,2,3,4,5,6,7,9,2,4);
var duplicate = false;
for (i=0;i<a.length;i++){
duplicate = false;
for(j=0;j<a.length;j++){
if(i != j && a[i]==a[j])
duplicate = true;
}
if(duplicate)
document.write('<span style="background-color:red;">')
document.write(a[i]);
if(duplicate)
document.write('</span>')
}
Create two events blur & keyup. On blur get the value from the input and push it in an array, on keyup check if the array contains the same value. If the value is present in the array then add a class to the target element or remove it
function Sum() {
alert("hi");
var num1 = Number(document.getElementById("qty1").value);
var num2 = Number(document.getElementById("qty2").value);
var num3 = Number(document.getElementById("qty3").value);
var num4 = Number(document.getElementById("qty4").value);
var num5 = Number(document.getElementById("qty5").value);
var num6 = Number(document.getElementById("qty6").value);
var num7 = Number(document.getElementById("qty7").value);
var num8 = Number(document.getElementById("qty8").value);
var num9 = Number(document.getElementById("qty9").value);
var sum = num1 + num2 + num3 + num4 + num5 + num6 + num7 + num8 + num9
document.getElementById("answer").value = sum;
}
let sumArray = []
document.querySelectorAll('input[type="number"]').forEach((item) => {
item.addEventListener('blur', (e) => {
sumArray.push(e.target.value)
})
item.addEventListener('keyup', (e) => {
if (sumArray.indexOf(e.target.value) !== -1) {
e.target.parentNode.classList.add('error')
} else if (e.target.parentNode.classList.contains('error')) {
e.target.parentNode.classList.remove('error')
}
})
})

its pretty simple just put same class in input field and loop through it like
In Html ,
<td>
<input type="number" class="checkSame" placeholder="input1" value="input1"id="qty1"></td>
<td>
<input type="number" class="checkSame" placeholder="input2" value="input2" id="qty2"></td>
<td>
<input type="number" class="checkSame" placeholder="input3"value="input3"id="qty3"></td>
then in javascript ,
var inputs = document.getElementsByClassName("checkSame");
var temp;
var count = 1;
for(var i = 0; i < inputs .length; i++)
{
temp = document.getElementsByClassName("checkSame")[i].value;
if(temp == document.getElementsByClassName("checkSame")[count++].value)
{
//change your background color here
break;
}
}
i think it works.
I hope this will help you to find duplicate fields
function Sum() {
alert("hi");
let arr = [];
let sum;
let duplicate = false;
for (let i = 1; i <= 9; i++) {
let num = Number(document.getElementById(`qty${i}`).value);
let indexOfDuplicateNum = arr.indexOf(num);
if (indexOfDuplicateNum > -1){
duplicate = true;
alert('Duplicate value found!');
document.getElementsByTagName('body')[0].style.background = 'red';
document.getElementById(`qty${i}`).classList.add('duplicate-error');
document.getElementById(`qty${indexOfDuplicateNum+1}`).classList.add('duplicate-error');
break;
} else{
//remove error class if value is not duplicate
document.getElementById(`qty${i}`).classList.remove('duplicate-error');
arr.push(num);
sum = arr.reduce((a, b) => a+b, 0);
}
}
if (!duplicate) {
document.getElementById('answer').value = sum;
document.getElementsByTagName('body')[0].style.background = 'white';
}
}

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

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];

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 manage to calculate total per row
now I need your help to sum all total and put the value in the grandtotal textbox
I guess on every change of a value of one of your input elements in your form the grand total should be updated, right? I 'd place an event listener on the form tag to keep it simple.
<form id="your-form" method="post" action="">
<!-- All your other inputs here -->
<input type="text" name="grandtotal" id="grandtotal">
</form>
<script>
document.querySelector('#your-form').addEventListener('change', function( event ) {
if (event.target.id && event.target.id !== 'grandtotal') {
var allTotals = document.querySelectorAll('input[name^="total"]'),
allTotalSum = 0;
Array.prototype.forEach.call(allTotals, function( element ) {
if (element.value) {
allTotalSum += parseFloat(element.value);
}
});
document.querySelector('#grandtotal').value = allTotalSum;
}
});
</script>
So on every change of one of your input fields the sum is updated. This code is untested.

how to find total value from adding value in html and value in dynamic form with javascript?

i have problem to find total_penjualan value.
i use dynamic form here. i want add all total's value in dynamic form with biayalainlain's value. i think the problem is in var ttl2 = document.getElementById(totalid).value; how to get id in additem() to put in prosestotal()?
this is my html and javascript code:
function sum() {
var hrg = document.getElementById('harga').value;
var jml = document.getElementById('jumlah').value;
var result = parseInt(hrg) * parseInt(jml);
if (!isNaN(result)) {
document.getElementById('total').value = result;
}
}
function additem() {
//menentukan target append
var itemlist = document.getElementById('itemlist');
// membuat element
var row = document.createElement('tr');

var kode = document.createElement('td');
var harga = document.createElement('td');
var jumlah = document.createElement('td');
var total = document.createElement('td');
var aksi = document.createElement('td');
// meng append element
itemlist.appendChild(row);
row.appendChild(nama);
row.appendChild(kode);
