I have a scoreboard where the user can enter the score and when the user presses the "Submit" button it will show a table that will contain the information that the user has entered. But when I try it in the browser, my table doesn't show the information that was entered in the previous form, it only show the table heading. Let me explain like below:
var testScore = {
name: "",
math: 0,
physical: 0,
chemistry: 0,
avg: 0
};
var i = 1;
// This is the table will show after submited
function score_table() {
document.getElementById("divTable").style.display = "block";
// Gathering the data
testScore.name = document.getElementById("name").value;
testScore.math = document.getElementById("math").value;
testScore.physical = document.getElementById("physics").value;
testScore.chemistry = document.getElementById("chemical").value;
testScore.avg = (parseFloat(testScore.math) + parseFloat(testScore.physics) + parseFloat(testScore.chemistry)) / 3;
// How to get this average score has the form like 8,33 or 6,69, I need //help
document.getElementById("name").value = "";
document.getElementById("math").value = "";
document.getElementById("physics").value = "";
document.getElementById("chemical").value = "";
// Add the information but why it does not work
var table = document.getElementById("tableScore");
var row = table.insertRow(i);
var number = row.insertCell(0);
var name = row.insertCell(1);
var math = row.insertCell(2);
var physics = row.insertCell(3);
var chemistry = row.insertCell(4);
var avg = row.insertCell(5);
number.innerHtml = i;
name.innerHtml = testScore.name;
math.innerHtml = testScore.math;
physics.innerHtml = testScore.physics;
chemistry.innerHtml = testScore.chemistry;
avg.innerHtml = testScore.avg;
i++;
}
#divTable {
display: none;
width: 100%;
}
#tableScore th:nth-child(6),
#tableScore td:nth-child(6) {
display: none;
}

In js code you have used innerHtml instead of innerHTML.
Updated code:
var testScore = {
name: "",
math: 0,
physical: 0,
chemistry: 0,
avg: 0
};
var i = 1;
// This is the table will show after submited
function score_table() {
document.getElementById("divTable").style.display = "block";
// Gathering the data
testScore.name = document.getElementById("name").value;
testScore.math = document.getElementById("math").value;
testScore.physical = document.getElementById("physics").value;
testScore.chemistry = document.getElementById("chemical").value;
testScore.avg = (parseFloat(testScore.math) + parseFloat(testScore.physics) + parseFloat(testScore.chemistry)) / 3;
// How to get this average score has the form like 8,33 or 6,69, I need //help
document.getElementById("name").value = "";
document.getElementById("math").value = "";
document.getElementById("physics").value = "";
document.getElementById("chemical").value = "";
// Add the information but why it does not work
var table = document.getElementById("tableScore");
var row = table.insertRow(i);
var number = row.insertCell(0);
var name = row.insertCell(1);
var math = row.insertCell(2);
var physics = row.insertCell(3);
var chemistry = row.insertCell(4);
var avg = row.insertCell(5);
number.innerHTML = i;
name.innerHTML = testScore.name;
math.innerHTML = testScore.math;
physics.innerHTML = testScore.physics;
chemistry.innerHTML = testScore.chemistry;
avg.innerHTML = testScore.avg;
i++;

When you use insertCell you need to use innerHTML or appendChild instead of the non-existent innerHtml
Also you do not need to have any integer in insertCell/Row
Also your HTML was invalid
number.appendChild(document.createTextNode(i));
name.appendChild(document.createTextNode(testScore.name));
math.appendChild(document.createTextNode(testScore.math));
physics.appendChild(document.createTextNode(testScore.physics));
chemistry.appendChild(document.createTextNode(testScore.chemistry));
avg.appendChild(document.createTextNode(testScore.avg));
var testScore = {
name: "",
math: 0,
physical: 0,
chemistry: 0,
avg: 0
};
var i = 1;
// This is the table will show after submited
function score_table() {
document.getElementById("divTable").style.display = "block";
// Gathering the data
testScore.name = document.getElementById("name").value;
testScore.math = document.getElementById("math").value;
testScore.physics = document.getElementById("physics").value;
testScore.chemistry = document.getElementById("chemical").value;
testScore.avg = (parseFloat(testScore.math) + parseFloat(testScore.physics) + parseFloat(testScore.chemistry)) / 3;
// How to get this average score has the form like 8,33 or 6,69, I need //help
document.getElementById("name").value = "";
document.getElementById("math").value = "";
document.getElementById("physics").value = "";
document.getElementById("chemical").value = "";
// Add the information but why it does not work
var table = document.querySelector("#tableScore tbody");

You have some misspelled variables but you can also minimize your output with only one global innerHTML like in my example below:
var testScore = {
name: "",
math: 0,
physical: 0,
chemistry: 0,
avg: 0
};
var i = 1;
// This is the table will show after submited
function score_table() {
document.getElementById("divTable").style.display = "block";
// Gathering the data
testScore.name = document.getElementById("name").value;
testScore.math = document.getElementById("math").value;
testScore.physical = document.getElementById("physics").value;
testScore.chemistry = document.getElementById("chemical").value;
testScore.avg = (parseFloat(testScore.math) + parseFloat(testScore.physics) + parseFloat(testScore.chemistry)) / 3;
// How to get this average score has the form like 8,33 or 6,69, I need //help
document.getElementById("name").value = "";
document.getElementById("math").value = "";
document.getElementById("physics").value = "";
document.getElementById("chemical").value = "";
//MINIMIZED VERSION
document.getElementById("tableScore").innerHTML +=
"<td>" + i + "</td>" +
"<td>" + testScore.name + "</td>" +
"<td>" + testScore.math + "</td>" +
"<td>" + testScore.physical + "</td>" +

I have a form within a table with Title and description columns and the rows can be added dynamically by a button. I need to access and save the input values in text boxes created by javascript function when saving the form by save button. the input values are later saved on local storage. The saved values are used to repopulate the form in case of unsuccessful validation.
function add_text_input() {
var table = document.getElementById('mytable');
var x = table.rows.length;
table.insertRow(-1).innerHTML = '<tr>' +
'<td> <input type="text" id="title' + x + '" /></td>' +
'<td> <input type="text" id="description' + x + '" /></td></tr>';
}
function save_data() {
var table = document.getElementById('mytable');
var tableRows = table.rows.length;
var data = [];
for (var i = 1; i <= tableRows; i++) {
for (var j = 0; j < 2; j++) {
var title = document.getElementById('title' + i).value;
var desc = document.getElementById('description' + i).value;
var temp = {
title: title,
description: desc
};
data.push(temp);
}
}
window.localStorage.setItem('Table1', JSON.stringify(data));
}
<form>
<table id="mytable">
<tr>
<td> Title </td>
<td> Description </td>
</tr>
</table>
<input type="button" onclick="add_text_input()" value="add row">
<input type="button" onclick="save_data()" value="save">
</form>
did you mean something like this?
$(document).ready(()=>{
$('#container').append('<input id="addedTxt" type="text" />');
$('#addedTxt').val('Test');
$('#saveBtn').on('click', ()=>{
alert($('#addedTxt').val());
});
});
<div id="container">
</div>
<input id="saveBtn" type="button" value="save" />
(using jquery)

or where is the problem?
In your code why you use the second For loop? I think it is not necessary.
find the working code snippet

what i have implemented so far:
Enter the values in the input fields and click " Add" button , The entered values gets added to the new row .
And When i click delete button, all the rows are getting deleted .
What I need to implement :
Checkbox should get added to every row .
If i select the checkbox and click "delete" button, only that particular row should get deleted and it should work if i select multiple check boxes as well.
3.Clear the Input fields after i click add button .
Can anyone check this out and tell me how to do that .
//Javascript code to Add new rows onclick of a button and to delete row .
function addMoreRows() {
var user = document.getElementById('user_id').value;
var date = document.getElementById('date').value;
var color = document.getElementById('color').value;
var table = document.getElementById('tbl_id');
var row = table.insertRow();
var userName = row.insertCell(0);
var Date = row.insertCell(1);
var Color = row.insertCell(2);
var checkbox = row.insertCell(3);
userName.innerHTML = user;
Date.innerHTML = date;
Color.innerHTML = color;
}
function deleteMoreRows(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for (var i = 0; i < rowCount; i++) {
table.deleteRow(i);
rowCount--;
i--;
}
}

How I can insert all data from a generated HTML table into my database using PHP?
I have tried with a foreach loop, but it gives me an error all the time.
I have this code in JavaScript to adding a new row using a button:
var i=1;
function addRow()
{
var tbl = document.getElementById('table1');
var lastRow = tbl.rows.length;
var iteration = lastRow - 1;
var row = tbl.insertRow(lastRow);
var firstCell = row.insertCell(0);
var el = document.createElement('input');
el.type = 'text';
el.name = 'to' + i;
el.id = 'to' + i;
el.size = 40;
firstCell.appendChild(el);
var secondCell = row.insertCell(1);
var el2 = document.createElement('input');
el2.type = 'text';
el2.name = 'cost' + i;
el2.id = 'cost' + i;
el2.size = 40;
secondCell.appendChild(el2);
frm.h.value=i;
i++;
}
And this is my HTML code:
<table id="table1" width="40%" border="2" cellpadding="0" cellspacing="0">
<tr>
<td><strong>To Address</strong></td>
<td><strong>Delivery Cost</strong></td>
</tr>
<tr>
<td><input name="to" type="text" id="to" size="40"/></td>
<td><input name="cost" type="text" id="cost" size="40"/></td>
</tr>
</table>
<br/><br/>
<input style="float: right;background-color: #57a000;height: 30px;font-weight: bold; font-family: cursive;margin-left: 10px;"
type="submit" value="Save All" name="SaveCost"/>
<input style="float: right;background-color: #57a000;height: 30px;font-weight: bold; font-family: cursive;"
type="button" value="Add New Place" onclick="addRow();"/>
<input name="h" type="hidden" id="h" value="0"/>
Finally I want to write some PHP to insert all the data from the generated HTML table into my database.
I have this code that a user can upload pictures. It works just fine, but the user can submit unlimited pictures, and I want to put a limit to four.
when the user reaches four input fields then they won't be allowed to add any input.
<script type="text/javascript">
function addItems()
{
var table1 = document.getElementById('tab1');
var newrow = document.createElement("tr");
var newcol = document.createElement("td");
var input = document.createElement("input");
input.type="file";
input.name="image[]";
newcol.appendChild(input);
newrow.appendChild(newcol);
table1.appendChild(newrow);
}
function remItems()
{
var table1 = document.getElementById('tab1');
var lastRow = table1.rows.length;
if(lastRow>=2)
table1.deleteRow(lastRow-1);
}
</script>
<form method="post" action="" enctype="multipart/form-data">
<table align="center" border="0" id="tab1">
<tr>
<td width="218" align="center">
<input type="file" name="image[]" /></td>
<td width="54" align="center">
<img src="Button-Add-icon.png" alt="Add" style="cursor:pointer"
onclick="addItems()" /></td>
<td>
<img src="Button-Delete-icon.png" alt="Remove" style="cursor:pointer"

</tr>
</table>
<table align="center" border="0" id="tab2">

</table>
</form>
Thanks
Add a global counter.. and check on your addItems function.. something like:
var totalItems = 0;
function addItems()
{
if(totalItems < 4) {
var table1 = document.getElementById('tab1');
var newrow = document.createElement("tr");
var newcol = document.createElement("td");
var input = document.createElement("input");
input.type="file";
input.name="image[]";
newcol.appendChild(input);
newrow.appendChild(newcol);
table1.appendChild(newrow);
totalItems++; //increment the global counter...
} else {
//Display your message here.. with an alert or something...
}
}
function remItems()
{
var table1 = document.getElementById('tab1');
var lastRow = table1.rows.length;
if(lastRow>=2) {
table1.deleteRow(lastRow-1);
totalItems--;
}
}
