studentInfo.points++

}
}

. use in php to concat string
+ use in javascript to concat string
try like this
cell3.innerHTML =studentInfo[index]+
'<input type="checkbox" name="student attendance" value="absent" id="checkboxab"</input>';

I think that you are confusing PHP string concatenating with Javascript string concatenating:
PHP
$variable = $other_variable . '<span>hello world</span>'
Javascript
var variable = other_variable + '<span>hello world</span>'
I get it?

The dot is a syntax error. You should use a +.
cell3.innerHTML = studentInfo[index].
'<input type="checkbox" name="student attendance" value="absent" id="checkboxab"</input>';
If you don't have another way to validate your JS, put it into a jsfiddle and press JSHint.

How to show JSON response in datatable using JavaScript [duplicate]

I have an HTML table with a header and a footer:
<table id="myTable">
<thead>
<tr>
<th>My Header</th>
</tr>
</thead>
<tbody>
<tr>
<td>aaaaa</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>My footer</td>
</tr>
<tfoot>
</table>
I am trying to add a row in tbody with the following:
myTable.insertRow(myTable.rows.length - 1);
but the row is added in the tfoot section.
How do I insert tbody?

If you want to add a row into the tbody, get a reference to it and call its insertRow method.
var tbodyRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];
// Insert a row at the end of table
var newRow = tbodyRef.insertRow();
// Insert a cell at the end of the row
var newCell = newRow.insertCell();
// Append a text node to the cell
var newText = document.createTextNode('new row');
newCell.appendChild(newText);
<table id="myTable">
<thead>
<tr>
<th>My Header</th>
</tr>
</thead>
<tbody>
<tr>
<td>initial row</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>My Footer</td>
</tr>
</tfoot>
</table>
(old demo on JSFiddle)

You can try the following snippet using jQuery:
$(table).find('tbody').append("<tr><td>aaaa</td></tr>");

Basic approach:
This should add HTML-formatted content and show the newly added row.
var myHtmlContent = "<h3>hello</h3>"
var tableRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];
var newRow = tableRef.insertRow(tableRef.rows.length);
newRow.innerHTML = myHtmlContent;

I think this script is what exactly you need
var t = document.getElementById('myTable');
var r =document.createElement('TR');
t.tBodies[0].appendChild(r)

You're close. Just add the row to the tbody instead of table:
myTbody.insertRow();
Just get a reference to tBody (myTbody) before use. Notice that you don't need to pass the last position in a table; it's automatically positioned at the end when omitting argument.
A live demo is at jsFiddle.

Add rows:
<html>
<script>
function addRow() {
var table = document.getElementById('myTable');
//var row = document.getElementById("myTable");
var x = table.insertRow(0);
var e = table.rows.length-1;
var l = table.rows[e].cells.length;
//x.innerHTML = " ";
for (var c=0, m=l; c < m; c++) {
table.rows[0].insertCell(c);
table.rows[0].cells[c].innerHTML = " ";
}
}
function addColumn() {
var table = document.getElementById('myTable');
for (var r = 0, n = table.rows.length; r < n; r++) {
table.rows[r].insertCell(0);
table.rows[r].cells[0].innerHTML = " ";
}
}
function deleteRow() {
document.getElementById("myTable").deleteRow(0);
}
function deleteColumn() {
// var row = document.getElementById("myRow");
var table = document.getElementById('myTable');
for (var r = 0, n = table.rows.length; r < n; r++) {
table.rows[r].deleteCell(0); // var table handle
}
}
</script>
<body>
<input type="button" value="row +" onClick="addRow()" border=0 style='cursor:hand'>
<input type="button" value="row -" onClick='deleteRow()' border=0 style='cursor:hand'>
<input type="button" value="column +" onClick="addColumn()" border=0 style='cursor:hand'>
<input type="button" value="column -" onClick='deleteColumn()' border=0 style='cursor:hand'>
<table id='myTable' border=1 cellpadding=0 cellspacing=0>
<tr id='myRow'>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
</body>
</html>
And cells.

let myTable = document.getElementById('myTable').getElementsByTagName('tbody')[0];
let row = myTable.insertRow();
let cell1 = row.insertCell(0);
let cell2 = row.insertCell(1);
let cell3 = row.insertCell(2);
cell1.innerHTML = 1;
cell2.innerHTML = 'JAHID';
cell3.innerHTML = 23;
row = myTable.insertRow();
cell1 = row.insertCell(0);
cell2 = row.insertCell(1);
cell3 = row.insertCell(2);
cell1.innerHTML = 2;
cell2.innerHTML = 'HOSSAIIN';
cell3.innerHTML = 50;
table {
border-collapse: collapse;
}
td, th {
border: 1px solid #000;
padding: 10px;
}
<table id="myTable">
<thead>
<tr>
<th>ID</th>
<th>NAME</th>
<th>AGE</th>
</tr>
</thead>
<tbody></tbody>
</table>

Add Column, Add Row, Delete Column, Delete Row. Simplest way
function addColumn(myTable) {
var table = document.getElementById(myTable);
var row = table.getElementsByTagName('tr');
for(i=0;i<row.length;i++){
row[i].innerHTML = row[i].innerHTML + '<td></td>';
}
}
function deleterow(tblId)
{
var table = document.getElementById(tblId);
var row = table.getElementsByTagName('tr');
if(row.length!='1'){
row[row.length - 1].outerHTML='';
}
}
function deleteColumn(tblId)
{
var allRows = document.getElementById(tblId).rows;
for (var i=0; i<allRows.length; i++) {
if (allRows[i].cells.length > 1) {
allRows[i].deleteCell(-1);
}
}
}
function myFunction(myTable) {
var table = document.getElementById(myTable);
var row = table.getElementsByTagName('tr');
var row = row[row.length-1].outerHTML;
table.innerHTML = table.innerHTML + row;
var row = table.getElementsByTagName('tr');
var row = row[row.length-1].getElementsByTagName('td');
for(i=0;i<row.length;i++){
row[i].innerHTML = '';
}
}
table, td {
border: 1px solid black;
border-collapse:collapse;
}
td {
cursor:text;
padding:10px;
}
td:empty:after{
content:"Type here...";
color:#cccccc;
}

You can also use querySelector to select the tbody, then insert a new row at the end of it.
Use append to insert Node or DOMString objects to a new cell, which will then be inserted into the new row.
var myTbody = document.querySelector("#myTable>tbody");
var newRow = myTbody.insertRow();
newRow.insertCell().append("New data");
<table id="myTable">
<thead>
<tr>
<th>My Header</th>
</tr>
</thead>
<tbody>
<tr>
<td>Data</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>My footer</td>
</tr>
</tfoot>
</table>

I have tried this, and this is working for me:
var table = document.getElementById("myTable");
var row = table.insertRow(myTable.rows.length-2);
var cell1 = row.insertCell(0);

You can use the following example:
<table id="purches">
<thead>
<tr>
<th>ID</th>
<th>Transaction Date</th>
<th>Category</th>
<th>Transaction Amount</th>
<th>Offer</th>
</tr>
</thead>
<!-- <tr th:each="person: ${list}" >
<td><li th:each="person: ${list}" th:text="|${person.description}|"></li></td>
<td><li th:each="person: ${list}" th:text="|${person.price}|"></li></td>
<td><li th:each="person: ${list}" th:text="|${person.available}|"></li></td>
<td><li th:each="person: ${list}" th:text="|${person.from}|"></li></td>
</tr>
-->
<tbody id="feedback">
</tbody>
</table>

$.ajax({
type: "POST",
contentType: "application/json",

for (var i = 0; i < data.length; i++) {

$('#feedback').append('<tr><td>' + data[i].accountNumber + '</td><td>' + data[i].category + '</td><td>' + data[i].ssn + '</td><td>' + data[i].ssn + '</td><td>' + data[i].ssn + '</td></tr>');
alert(data[i].accountNumber)
}
},
error: function (e) {
var json = "<h4>Ajax Response</h4><pre>" + e.responseText + "</pre>";

Make table via value

How do I do that JavaScript will print in my HTML page a table via the value the user will choose?
That the JS script:
let numCol = document.getElementById('txtColumns').value;
let numRow = document.getElementById('txtRows').value;
let go = document.getElementById('btn');
let table = document.getElementById('table');
let td = "<td></td>" * numCol;
let tr = ("<tr>" + td + "</tr>") * numRow;
go.addEventListener('click', function(){
table.innerHTML = tr;
})
That the HTML code:
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="style.css">
</head>
<body>
<table class="workTable">
<tr>
<td>
<input type="number" placeholder="Columns Number" id="txtColumns">
</td>
<td>
<input type="number" placeholder="Rows Number" id="txtRows">
</td>
</tr>
<tr>
<td colspan="2" align="center">
<button id="btn">
Print
</button>
</td>
</tr>
<div>
<table id="table">
<!--Here I want to print the table-->
</table>
</div>
</table>
<script src="script.js"></script>
</body>
</html>
At first I thought about that way with the script but its only appear as a NaN and not table...

The following syntax:
let td = "<td></td>" * numCol;
does not produce numCol cells, so the following syntax:
let tr = ("<tr>" + td + "</tr>") * numRow;
does not produce numRow rows also.
So, the whole source code should be:
let go = document.getElementById('btn');
let table = document.getElementById('table');
go.addEventListener('click', () => {
let numCol = document.getElementById('txtColumns').value; //Get the value of txtColumns at the button click moment.
let numRow = document.getElementById('txtRows').value;
let td = "",
tr = "";
for (let i = 0; i < numCol; i++) {
td = td + "<td></td>";
}
for (let i = 0; i < numRow; i++) {
tr = tr + "<tr>" + td + "</tr>";
}
table.innerHTML = tr;
})
<table class="workTable">
<tr>
<td>
<input type="number" placeholder="Columns Number" id="txtColumns">
</td>
<td>
<input type="number" placeholder="Rows Number" id="txtRows">
</td>
</tr>
<tr>
<td colspan="2" align="center">
<button id="btn">
Print
</button>
</td>
</tr>
<div>
<table id="table" border="1">

My submited table does not show on the browser

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++;

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() {

// 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 = "";

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));

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>" +
"<td>" + testScore.chemistry + "</td>" +
"<td>" + testScore.avg + "</td>";
i++;
}
#divTable {

}
#tableScore th:nth-child(6),
#tableScore td:nth-child(6) {

Moving data from one html table to another

I am struggling with something that should be so simple.
I am trying to move a row from one html table to another, basically a table with selection options and input to another table with the final selections and values.
Image for UI
My Html code is as follow,
function GetIndex()
{
var table = document.getElementById("table1");
var rows = table.getElementsByTagName("tr");
for (i = 0; i < rows.length; i++) {
var currentRow = table.rows[i];
var createClickHandler = function(row) {
return function() {
var cell = row.getElementsByTagName("td")[0];
var id = cell.innerHTML;
console.log("HERE " + id );
localStorage.setItem("ID", id);
};
};
currentRow.onclick = createClickHandler(currentRow);
AddNextTable();
}
}
function AddNextTable()
{
var ID= localStorage.getItem("ID");
var table1 = document.getElementById("table1"),
table2 = document.getElementById("table2");
var table = document.getElementById("table1");
var rows = table.getElementsByTagName("tr");
for (i = 0; i < rows.length; i++) {
var currentRow = table.rows[i];
var createClickHandler = function(row) {
return function() {
var cell = row.getElementsByTagName("td")[0];
var id = cell.innerHTML;
var Counter= 0;
Counter++;
var InputSelect= "input" + ID;
console.log(InputSelect);
var NewText= document.getElementById(InputSelect).value;
var newRow = table2.insertRow(table2.length),
cell1 = newRow.insertCell(0),
cell2 = newRow.insertCell(1),
cell3 = newRow.insertCell(2),
cell4 = newRow.insertCell(3);
cell1.innerHTML = table1.rows[id].cells[0].innerHTML;
cell2.innerHTML = table1.rows[id].cells[1].innerHTML;
cell3.innerHTML = table1.rows[id].cells[2].innerHTML;
cell4.innerHTML = "<input type='checkbox' name='check-tab2'>";
cell3.innerHTML= "<input type='text' value="+ NewText+ ">"
var index = table1.rows[1].rowIndex;
};
};
currentRow.onclick = createClickHandler(currentRow);
}
}
function tab2_To_tab1()
{
var table1 = document.getElementById("table1"),
table2 = document.getElementById("table2"),
checkboxes = document.getElementsByName("check-tab2");
console.log("Val1 = " + checkboxes.length);
for(var i = 0; i < checkboxes.length; i++)
if(checkboxes[i].checked)
{
// create new row and cells
var newRow = table1.insertRow(table1.length),
cell1 = newRow.insertCell(0),
cell2 = newRow.insertCell(1),
cell3 = newRow.insertCell(2),
cell4 = newRow.insertCell(3);
// add values to the cells
cell1.innerHTML = table2.rows[i+1].cells[0].innerHTML;
cell2.innerHTML = table2.rows[i+1].cells[1].innerHTML;
cell3.innerHTML = table2.rows[i+1].cells[2].innerHTML;
cell4.innerHTML = "<input type='checkbox' name='check-tab1'>";
// remove the transfered rows from the second table [table2]
var index = table2.rows[i+1].rowIndex;
table2.deleteRow(index);
// we have deleted some rows so the checkboxes.length have changed
// so we have to decrement the value of i
i--;
console.log(checkboxes.length);
}
}

My end goal will be for the user to enter a certain amount of an item in the first table, and have it display in the next. I am looping through something incorrectly somewhere.

I found it quite complicated about your code. Just why not giving it a param that describes which button/input called the function? It will be much easier and also this will no longer require the use of localStorage. Hope this solves your problem.
On the html:
<button onclick="GetIndex('input1')"></button>
On the js
function GetIndex(src) {
...
AddIndex(src);
...
}
function AddIndex(src) {
...
var ID = src;
...
}
function GetIndex(src)
{
var table = document.getElementById("table1");
var rows = table.getElementsByTagName("tr");
for (i = 0; i < rows.length; i++) {
var currentRow = table.rows[i];
var createClickHandler = function(row) {
return function() {
var cell = row.getElementsByTagName("td")[0];
var id = cell.innerHTML;
console.log("HERE " + id );
localStorage.setItem("ID", id);
};
};
currentRow.onclick = createClickHandler(currentRow);
AddNextTable(src);
}
}
function AddNextTable(src)
{
var table1 = document.getElementById("table1"),
table2 = document.getElementById("table2");
var table = document.getElementById("table1");
var rows = table.getElementsByTagName("tr");
for (i = 0; i < rows.length; i++) {
var currentRow = table.rows[i];
var createClickHandler = function(row) {
return function() {
var cell = row.getElementsByTagName("td")[0];
var id = cell.innerHTML;
var Counter= 0;
Counter++;
var InputSelect= src;
console.log(InputSelect);
var NewText= document.getElementById(InputSelect).value;
var newRow = table2.insertRow(table2.length),
cell1 = newRow.insertCell(0),
cell2 = newRow.insertCell(1),
cell3 = newRow.insertCell(2),
cell4 = newRow.insertCell(3);
cell1.innerHTML = table1.rows[id].cells[0].innerHTML;
cell2.innerHTML = table1.rows[id].cells[1].innerHTML;
cell3.innerHTML = table1.rows[id].cells[2].innerHTML;
cell4.innerHTML = "<input type='checkbox' name='check-tab2'>";
cell3.innerHTML= "<input type='text' value="+ NewText+ ">"
var index = table1.rows[1].rowIndex;
};
};
currentRow.onclick = createClickHandler(currentRow);
}
}
function tab2_To_tab1()
{
var table1 = document.getElementById("table1"),

I think you're overcomplicating.
You don't need localStorage, you don't need almost anything. Just a bit of JS .append() to move back and forth your rows. Than using CSS you can additionally pimp the desired items to show/hide or even the button text:
const moveTR = (ev) => {
const EL_tr = ev.currentTarget.closest("tr");
const sel = EL_tr.closest("table").id === "table1" ? "#table2" : "#table1";
document.querySelector(sel + " tbody").append(EL_tr);
};
document.querySelectorAll("table button")
.forEach(EL => EL.addEventListener("click", moveTR));
table {border-collapse: collapse;}
th, td {border: 1px solid #ddd; padding: 5px 10px;}
#table1 button::after {content: "Add"}
#table2 button::after {content: "\2715"}
<table id="table1">
<thead>
<tr><th>Code</th><th>Name</th><th>Amount</th><th>Action</th></tr>
</thead>
<tbody>
<tr>
<td>8</td><td>Fred</td><td><input type="text"></td>
<td><button type="button"></button></td>
</tr>
<tr>
<td>4</td><td>Dean</td><td><input type="text"></td>
<td><button type="button"></button></td>
</tr>
<tr>
<td>1</td><td>Mark</td><td><input type="text"></td>
<td><button type="button"></button></td>
</tr>
</tbody>
</table>
<table id="table2">
<thead>
<tr><th>Code</th><th>Name</th><th>Amount</th><th>Action</th></tr>
</thead>
<tbody>
</tbody>
</table>

Insert a row in a table based on a value of another row with user input

I'm trying to find a way to insert a row in a table based on a value that the user inputs and if that value exists in the table. For example, the table will have 10 rows. The user would like to add a row beneath row number 8. Please see screenshot.
<form>
<table class="myTable" id="myTable">
<tr>
<th class="myTable th">PALLET #</th>
<th class="myTable th">CASE COUNT</th>
<th class="myTable th">HILLTOP LOT #</th>
<th class="myTable th">SSCC (LAST 4)</th>
</tr>
<?php
for ($x=1 ; $x <=2 4; $x++) {
echo
'<tr>
<td style="font-size: 160%" id="pallet">' .$x. '</td>
<td id="caseCount"><input type="text" id="inputText_Small" name="caseCount" value="" maxlength="2"/></td>
<td id="hilltopLot"><input type="text" id="inputText_Order" name="hilltopLot" value="" maxlength="10"/></td>
<td id="sscc"><input type="text" id="inputText_Medd" name="sscc" value="" maxlength="4"/></td>
</tr>';
}
?>
</table>
After clicking on the "Add Line" button and typing 8, it will look for row number 8 and insert a row beneath it also naming it row 8.
<br />
<br />
<p class="center">
<input type="submit" value="Submit" name="submit" class="blueButt_Big" />&nbsp&nbsp
<input class="blueButt_Big" type="button" value="Cancel" onclick="parent.location='view_prodLine.php'" />&nbsp&nbsp
<input class="blueButt_Big" type="button" value="Add Line" onclick="addLine()" />&nbsp&nbsp
<input class="blueButt_Big" type="button" value="Delete Line" onclick="myDeleteFunction()" />
</form>
<script>
function addLine() {
var person = prompt("Please enter the pallet number");
if (person != null) {
var table = document.getElementById("myTable");
var row = table.insertRow(-1);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
cell1.innerHTML = person;
cell2.innerHTML = '<input type="text" id="inputText_Small" name="caseCount" value="" maxlength="2"/>';
cell3.innerHTML = '<input type="text" id="inputText_Order" name="hilltopLot" value="" maxlength="10"/>';
cell4.innerHTML = '<input type="text" id="inputText_Medd" name="sscc" value="" maxlength="4"/>';
I've only been able to add a row to the very bottom of the table after prompting the user for input. I know I can specify where the row is inserted using the code I commented out. The obvious problem is that the position where it will insert the new row will change if the user adds more than one line. I fear I may be overthinking it, any thoughts?
//var x = document.getElementById("myTable").rows[22].cells;
//x[0].innerHTML = person;
}
}
function myDeleteFunction() {
document.getElementById("myTable").deleteRow(-1);
}
</script>

You can do it this way:
<table id="myTable">
<tr>
<td>Row1 cell1</td>
<td>Row1 cell2</td>
</tr>
<tr>
<td>Row2 cell1</td>
<td>Row2 cell2</td>
</tr>
<tr>
<td>Row3 cell1</td>
<td>Row3 cell2</td>
</tr>
</table>
<br>
<input type="number" id="RowNumber"/>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction() {
var RowNumber = document.getElementById("RowNumber").value;
var table = document.getElementById("myTable");
var row = table.insertRow(RowNumber);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
cell1.innerHTML = "NEW CELL1";
cell2.innerHTML = "NEW CELL2";
}
</script>

Uncaught SyntaxError: Unexpected string in my Javascript code - javascript

. use in php to concat string + use in javascript to concat string try like this cell3.innerHTML =studentInfo[index]+ '<input type="checkbox" name="student attendance" value="absent" id="checkboxab"</input>';

I think that you are confusing PHP string concatenating with Javascript string concatenating: PHP $variable = $other_variable . '<span>hello world</span>' Javascript var variable = other_variable + '<span>hello world</span>' I get it?

The dot is a syntax error. You should use a +. cell3.innerHTML = studentInfo[index]. '<input type="checkbox" name="student attendance" value="absent" id="checkboxab"</input>'; If you don't have another way to validate your JS, put it into a jsfiddle and press JSHint. http://jsfiddle.net/mgb8x7pd/
