How do I display a dynamically created html table only once?

Each time I input another football score, the league table is updated and displayed but it's appended to a list of tables. How do I display only the latest table?
Here is an extract of the html:
<div>
<table id="matches" border="1"> </table>
</div>
<div>
<table id="standings" border="1"> </table>
</div>
<input type="button" value="Update" onclick="update()" />
Here is the javascript that displays the fixtures for inputting scores:
// Display fixtures to input the scores
window.onload = function()
{
table = document.getElementById("matches");
var row;
var cell1;
var cell2;
var cell3;
for (i = 1; i < Results.length; i++)
{
row = table.insertRow(i-1); //table starts row 0 but Results row 1 so i-1 used
cell1 = row.insertCell(0);
cell2 = row.insertCell(1);
cell3 = row.insertCell(2);
cell4 = row.insertCell(3);
cell1.innerHTML = Results[i][0];
cell2.innerHTML = '<input type="number" min="0" max="99"/>'
cell3.innerHTML = '<input type="number" min="0" max="99"/>'
cell4.innerHTML = Results[i][3];
}
}
And here is the code that displays the table after the lastest scores have been inputed:
// Display League Table
standings = document.getElementById("standings");
for (i = 0; i < League.length; i++)
{
row = standings.insertRow(i);
cell1 = row.insertCell(0);
cell2 = row.insertCell(1);
cell3 = row.insertCell(2);
cell4 = row.insertCell(3);
cell5 = row.insertCell(4);
cell6 = row.insertCell(5);
cell7 = row.insertCell(6);
cell8 = row.insertCell(7);
cell1.innerHTML = League[i][0];
cell2.innerHTML = League[i][1];
cell3.innerHTML = League[i][2];
cell4.innerHTML = League[i][3];
cell5.innerHTML = League[i][4];
cell6.innerHTML = League[i][5];
cell7.innerHTML = League[i][6];
cell8.innerHTML = League[i][7];
}
After entering three scores this is what is displayed:
I've tried clearing the league array within javascript but still the same outcome. How do I only display top version of the table? Thanks

Thanks again to comments, and some further googling, the following deletes the table ahead of updating it, unless there's a better way?
for(var i = standings.rows.length - 1; i >= 0; i--)
{
standings.deleteRow(i);
}
Cheers everyone! :)

For your table update/question, focus on the updateRow function. This line does the actual update of contents of row rownum column(<td>) i
rows[rownum].getElementsByTagName('td')[i].innerHTML = coldata[i];
There is more here than just updating the table rows, for that you can review the function updateRow in my name-spaced object. updateRow calls createRow if it needs to (the row at that index does not exist), nothing fancy here, then updates the new row.
I use the array of match objects in matches I created (was not one in the question so I made assumptions) also in the namespace:
matches: [{
match: 1,
score: [{
team: "Ap",
score: 3
}, {
team: "Or",
score: 2
}]
}],
Note where I call this code to update the table for standings in the table with standings-table id. I have no idea what those are so I simply inserted some stuff in the array then update the table using
for (let i = 0; i < myLeague.standings.length; i++) {
myLeague.updateRow('standings-table', myLeague.standings[i], i);
}
Other things: I created the form simply to show how to update the table when a new match is inserted, I trigger an event and it does what it needs to update or insert a row - but really that is just to test the update as new matches are created.
Row in a table are either updated or inserted depending totally on the array of matches content
nothing handles deletions from the table or array since this was just about insert and update
if a row index for a match index does not exist, it creates a new row and updates it
var myLeague = myLeague || {
teamSelect1: "team1",
teamSelect2: "team2",
matchesPlayed: 1,
teams: [{
name: "Apples",
abbreviation: "Ap"
},
{
name: "Oranges",
abbreviation: "Or"
},
{
name: "Pears",
abbreviation: "Pe"
}
],
matches: [{
match: 1,
score: [{
team: "Ap",
score: 3
}, {
team: "Or",
score: 2
}]
}],
standings: [
["A", 2, 1, 1, 3, 2, 3, 0],
["B", 3, 1, 1, 3, 2, 3, 6]
],

Onchange in dynamic table only updates input textbox in first row

I want to thank you guys for your response and assistance rendered so far, i am greatful but please i wouldn't mind if you don't get tired on me.
Thanks.
Please i need help with my dynamic table, everything seems to be working fine except for my onchange event for each dynamically added row, it only inserts into the first row, but when i select an option from the second added row, the feilds to be updated from the database remains blank.
I used alert to check, and the onchange seems to be working on all rows just that it is only the first row that changes are effected to the required fields. Bellow is my code for your review.
php script at the top of the page that populates select option data from the database
<?php
$query1 = "SELECT * FROM products";
$result1 = mysqli_query($con, $query1);
$options = "";
while($row3 = mysqli_fetch_array($result1))
{
$options = $options."<option value='$row3[1]'>$row3[2]</option>";
}
?>

Already mentoined here, but still: How to submit form on change of dropdown list? . When user submits form, use php fetch from databse, with isset($_POST['name'])

I was able to fix it with making the some changes in my get_item() javascript function
function get_item(dropDown){
$.ajax({
method:"POST",
url:"get_item.php",
data:{item:dropDown.value},
success:function(data){
alert(data);

thanks everyone.

How to get values from option-list into consecutive input-fields by onclick-function

I have a html-form to read out data from a database.
By clicking a button, there is the possibility to create additional input fields.
<table>
<tr>
<td>
<input type="text" id="productinput" name="productinput[]" class="awesomplete" list="productselect" size="20"/>
</td>
</tr>
<tr>
<td>
<input type="text" id="productinput2" name="productinput[]" class="awesomplete" list="productselect" size="20"/>
</td>
</tr>
<tr>
<td>
<input type="text" id="productinput3" name="productinput[]" class="awesomplete" list="productselect" size="20"/>
</td>
</tr>
</table>
<script>
var counter = 1;
var limit = 10;
function addInput(divName){
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
}
else {
// Create new div
var newdiv = document.createElement('div');
newdiv.innerHTML = '<br><input type="text" name="productinput[]" class="awesomplete" list="productinputselect" size="20"/>';
document.getElementById(divName).appendChild(newdiv);
// Re instantiate Awesomplete
new Awesomplete(newdiv.querySelector('input'), { list: document.querySelector('#productinputselect') });
// Set counter
counter++;
}
}
</script>
<div id="dynamicInput">
<b></b><input type="text" id="productinput4" name="productinput[]" class="awesomplete" list="productinputselect" size="20"/>
</div>
<input type="button" value="Additional Input Field" onClick="addInput('dynamicInput');">
<select name="productselect" id="productselect" size="9" onclick="sendproductnameinput()">
<?php
include("../files/zugriff.inc.php"); // database access
$sql = "SELECT * FROM product_main ORDER BY Name";
$result = mysqli_query($db, $sql);
while ($row = mysqli_fetch_assoc($result)) {
echo '<option class="optproduct" value='. $row['Name'] . '>' . $row['Name']. '</option>';
echo '<br>';
}
mysqli_close($db);
?>
</select>
So far, this works fine!
By using the following javascript-function the selected value from the -list is displayed in the first input-field.
function sendproductnameinput() {
document.formdatabase.productinput.value = document.formdatabase. productselect.value;
}
How can I get the next selected value in the second input-field and so on? This function should work in the additionally added fields, too.

You can use this :
for (var i = document.formdatabase.length - 1; i >= 0; i--) {
document.formdatabase[i].value = document.formdatabase.productselect.value;
}
Your Select seems to be not Multiple select, so I suppose you want to put the same selected value in each input.
And if multiple select than you can use this:
function getSelectValues(select) {
var result = [];
var options = select && select.options;
var opt;
for (var i=0, iLen=options.length; i<iLen; i++) {
opt = options[i];
if (opt.selected) {
result.push(opt.value || opt.text);
}
}
return result;
}
function sendproductnameinput() {
var selected = getSelectValues(document.formdatabase.productselect);
for (var i = document.formdatabase.length - 1; i >= 0; i--) {
if(i < selected.length) {
document.formdatabase[i].value = selected[i];
}
}
}
here is a fiddle https://jsfiddle.net/586menbv/16/

Well, it depends on where the function sendproductnameinput() is defined, but if the variable counter is visible from it's scope, I would dare to write something like this:
var timesSomethingSelected = 1;
function sendproductnameinput() {
var productinput = 'productinput';
if(timesSomethingSelected > 1) {
productinput += timesSomethingSelected;
timesSomethingSelected++;
} else if(timesSomethingSelected == counter) {
//Do something if there aren't more inputs.
}
document.formdatabase[productinput].value = document.formdatabase. productselect.value;
}

Get values from dynamic table and draws it with google charts

I'm trying to get the values from the dynamic table and after that I want draw it with Google charts, but the code doesn't work, I can't understand what's the problem. I think the problem is related to the method that I use to get the value from the table, but I'm not sure.
When I get the values and I try to draw it, Google returns the following error:
Data column(s) for axis #0 cannot be of type string
Can anyone help me to fix my code please?

You should try to narrow down your questions and post only related code.
The problem you have is you're not converting your HTML Table values from strings to numbers when you add the values from the table to your "dataArray", which causes the whole input to try to represent strings with numbers.
I modified your array building loop, and added if(i > 0) (if it's not the first row (the headings) anymore). Whole loop now looks like:
for (var i=0;i<valori.rows.length;i++) {
f[i]=new Array();
for (var j=0;j<valori.rows[i].cells.length;j++) {
if(i > 0){
f[i][j]= Number(valori.rows[i].cells[j].innerHTML);
}else{
f[i][j]= valori.rows[i].cells[j].innerHTML;
}
}
}
and it now works like a charm.

Javascript: fetch values from textbox of a dynamic datagrid. (skipping some textboxes)

i have seen similar questions to this but none can assist me.as my code is missing some results and i don't now why.
as seen on the image above the output is 6 results instead of 12
This is the code am using to get the values
//Fetch Sales**********************************************
function fetchsales(){
var Dt = document.getElementById("sDate").value;
var Usr = document.getElementById("UserID").value;
var Stp = document.getElementById("tstamp").value;
var e = document.getElementById("sdepot");
var Dpt = e.options[e.selectedIndex].value;
var sale = new Array();
var Tbl = document.getElementById('tbl_sales'); //html table
var tbody = Tbl.tBodies[0]; // Optional, based on what is rendered
for (var i = 2; i < tbody.rows.length; i++) {
var row = tbody.rows[i];
for (var j = 2; j < row.cells.length; j++) {
var cell = row.cells[j];
// For Every Cell get the textbox value
var unitsold = cell.childNodes[0].value ;
//Get selectbox distributor
var Sdist = row.cells[1].childNodes[0]; //Select box always on second coloumn
var Distributor = Sdist.options[Sdist.selectedIndex].value;
//Get selectbox Product
var Sprod = tbody.rows[1].cells[j].childNodes[0];
var Product = Sprod.options[Sprod.selectedIndex].value;
sale[(j*i)] = new Array ('('+Dt,Dpt,Product,unitsold,Distributor,Usr,Stp+')<br/>');
}
}
//Debug
var fsale = new Array();
fsale = sale.filter(function(n){return n});
document.getElementById("output").innerHTML = fsale;
}
//End Fetch Sales******************************************************

NB: am hoping to concatenate the result to a mysql insert statement
Any assistance will be greatly appreciated.

The problem comes from this line:
sale[(j*i)] = new Array ('('+Dt,Dpt,Product,unitsold,Distributor,Usr,Stp+')<br/>');
using the for loops indexes multiplied by themselves doesnt ensure unique array indexes, in some cases they are repeated (like for example 2*3 and 3*2) and the previous value in the array gets overwritten.
