Dynamic creation of table with DOM

Dynamic creation of table with DOM - javascript

Can someone tell me what's wrong with this code? I want to create a table with 2 columns and 3 rows, and in the cells I want Text1 and Text2 on every row. This code creates a table with 2 columns and 3 rows, but it's only text in the cells in the third row (the others are empty).
var tablearea = document.getElementById('tablearea');
var table = document.createElement('table');
var tr = [];
var td1 = document.createElement('td');
var td2 = document.createElement('td');
var text1 = document.createTextNode('Text1');
var text2 = document.createTextNode('Text2');
for (var i = 1; i < 4; i++){
tr[i] = document.createElement('tr');
for (var j = 1; j < 4; j++){
td1.appendChild(text1);
td2.appendChild(text2);
tr[i].appendChild(td1);
tr[i].appendChild(td2);
}
table.appendChild(tr[i]);
}
tablearea.appendChild(table);

You must create td and text nodes within loop. Your code creates only 2 td, so only 2 are visible. Example:
var table = document.createElement('table');
for (var i = 1; i < 4; i++){
var tr = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
var text1 = document.createTextNode('Text1');
var text2 = document.createTextNode('Text2');
td1.appendChild(text1);
td2.appendChild(text2);
tr.appendChild(td1);
tr.appendChild(td2);
table.appendChild(tr);
}
document.body.appendChild(table);

It is because you're only creating two td elements and 2 text nodes.
Creating all nodes in a loop
Recreate the nodes inside your loop:
var tablearea = document.getElementById('tablearea'),
table = document.createElement('table');
for (var i = 1; i < 4; i++) {
var tr = document.createElement('tr');
tr.appendChild( document.createElement('td') );
tr.appendChild( document.createElement('td') );
tr.cells[0].appendChild( document.createTextNode('Text1') )
tr.cells[1].appendChild( document.createTextNode('Text2') );
table.appendChild(tr);
}
tablearea.appendChild(table);
Creating then cloning in a loop
Create them beforehand, and clone them inside the loop:
var tablearea = document.getElementById('tablearea'),
table = document.createElement('table'),
tr = document.createElement('tr');
tr.appendChild( document.createElement('td') );
tr.appendChild( document.createElement('td') );
tr.cells[0].appendChild( document.createTextNode('Text1') )
tr.cells[1].appendChild( document.createTextNode('Text2') );
for (var i = 1; i < 4; i++) {
table.appendChild(tr.cloneNode( true ));
}
tablearea.appendChild(table);
Table factory with text string
Make a table factory:
function populateTable(table, rows, cells, content) {
if (!table) table = document.createElement('table');
for (var i = 0; i < rows; ++i) {
var row = document.createElement('tr');
for (var j = 0; j < cells; ++j) {
row.appendChild(document.createElement('td'));
row.cells[j].appendChild(document.createTextNode(content + (j + 1)));
}
table.appendChild(row);
}
return table;
}
And use it like this:
document.getElementById('tablearea')
.appendChild( populateTable(null, 3, 2, "Text") );
Table factory with text string or callback
The factory could easily be modified to accept a function as well for the fourth argument in order to populate the content of each cell in a more dynamic manner.
function populateTable(table, rows, cells, content) {
var is_func = (typeof content === 'function');
if (!table) table = document.createElement('table');
for (var i = 0; i < rows; ++i) {
var row = document.createElement('tr');
for (var j = 0; j < cells; ++j) {
row.appendChild(document.createElement('td'));
var text = !is_func ? (content + '') : content(table, i, j);
row.cells[j].appendChild(document.createTextNode(text));
}
table.appendChild(row);
}
return table;
}
Used like this:
document.getElementById('tablearea')
.appendChild(populateTable(null, 3, 2, function(t, r, c) {
return ' row: ' + r + ', cell: ' + c;
})
);

You need to create new TextNodes as well as td nodes for each column, not reuse them among all of the columns as your code is doing.
Edit:
Revise your code like so:
for (var i = 1; i < 4; i++)
{
tr[i] = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
td1.appendChild(document.createTextNode('Text1'));
td2.appendChild(document.createTextNode('Text2'));
tr[i].appendChild(td1);
tr[i].appendChild(td2);
table.appendChild(tr[i]);
}

You can create a dynamic table rows as below:
var tbl = document.createElement('table');
tbl.style.width = '100%';
for (var i = 0; i < files.length; i++) {
tr = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
var td3 = document.createElement('td');
::::: // As many <td> you want
td1.appendChild(document.createTextNode());
td2.appendChild(document.createTextNode());
td3.appendChild(document.createTextNode();
tr.appendChild(td1);
tr.appendChild(td2);
tr.appendChild(td3);
tbl.appendChild(tr);
}

when you say 'appendchild' you actually move your child from one parent to another.
you have to create a node for each cell.

In my example, serial number is managed according to the actions taken on each row using css. I used a form inside each row, and when new row created then the form will get reset.
/*auto increment/decrement the sr.no.*/
body {
counter-reset: section;
}
i.srno {
counter-reset: subsection;
}
i.srno:before {
counter-increment: section;
content: counter(section);
}

Hope this helps.

In My example call add function from button click event and then get value from form control's and call function generateTable.
In generateTable Function check first Table is Generaed or not. If table is undefined then call generateHeader Funtion and Generate Header and then call addToRow function for adding new row in table.
<input type="button" class="custom-rounded-bttn bttn-save" value="Add" id="btnAdd" onclick="add()">
<div class="row">
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
<div class="dataGridForItem">
</div>
</div>
</div>
//Call Function From Button click Event
var counts = 1;
function add(){
var Weightage = $('#Weightage').val();
var ItemName = $('#ItemName option:selected').text();
var ItemNamenum = $('#ItemName').val();
generateTable(Weightage,ItemName,ItemNamenum);
$('#Weightage').val('');
$('#ItemName').val(-1);
return true;
}
function generateTable(Weightage,ItemName,ItemNamenum){
var tableHtml = '';
if($("#rDataTable").html() == undefined){
tableHtml = generateHeader();
}else{
tableHtml = $("#rDataTable");
}
var temp = $("<div/>");
var row = addToRow(Weightage,ItemName,ItemNamenum);
$(temp).append($(row));
$("#dataGridForItem").html($(tableHtml).append($(temp).html()));
}
//Generate Header
function generateHeader(){
var html = "<table id='rDataTable' class='table table-striped'>";
html+="<tr class=''>";
html+="<td class='tb-heading ui-state-default'>"+'Sr.No'+"</td>";
html+="<td class='tb-heading ui-state-default'>"+'Item Name'+"</td>";
html+="<td class='tb-heading ui-state-default'>"+'Weightage'+"</td>";
html+="</tr></table>";
return html;
}
//Add New Row
function addToRow(Weightage,ItemName,ItemNamenum){
var html="<tr class='trObj'>";
html+="<td>"+counts+"</td>";
html+="<td>"+ItemName+"</td>";
html+="<td>"+Weightage+"</td>";
html+="</tr>";
counts++;
return html;
}

You can do that using LemonadeJS.
<html>
<script src="https://lemonadejs.net/v2/lemonade.js"></script>
<div id='root'></div>
<script>
var Component = (function() {
var self = {};
self.rows = [
{ title:'Google', description: 'The alpha search engine...' },
{ title:'Bind', description: 'The microsoft search engine...' },
{ title:'Duckduckgo', description: 'Privacy in the first place...' },
];
// Custom components such as List should always be unique inside a real tag.
var template = `<table cellpadding="6">
<thead><tr><th>Title</th><th>Description</th></th></thead>
<tbody #loop="self.rows">
<tr><td>{{self.title}}</td><td>{{self.description}}</td></tr>
</tbody>
</table>`;
return lemonade.element(template, self);
});
lemonade.render(Component, document.getElementById('root'));
</script>
</html>

Just create a new row inside the table, loop through the array and create a cell for each item.
Here's the code snippet for the same:
var arrHead = new Array();
arrHead = ['', 'Student Name', 'Department', 'Age'];
function createTable() {
var stuTable = document.createElement('table');
stuTable.setAttribute('id', 'stuTable');
var tr = stuTable.insertRow(-1);
for (var h = 0; h < arrHead.length; h++) {
var th = document.createElement('th');
th.innerHTML = arrHead[h];
tr.appendChild(th);
}
var div = document.getElementById('cont');
div.appendChild(stuTable);
}
function addRow() {
var stuTab = document.getElementById('stuTable');
var rowCnt = stuTab.rows.length;
var tr = stuTab.insertRow(rowCnt);
tr = stuTab.insertRow(rowCnt);
for (var c = 0; c < arrHead.length; c++) {
var td = document.createElement('td');
td = tr.insertCell(c);
if (c == 0) {
var button = document.createElement('input');
button.setAttribute('type', 'button');
button.setAttribute('value', 'Remove');
button.setAttribute('onclick', 'removeRow(this)');
td.appendChild(button);
} else {
var ele = document.createElement('input');
ele.setAttribute('type', 'text');
ele.setAttribute('value', '');
td.appendChild(ele);
}
}
}
function removeRow(oButton) {
var stuTab = document.getElementById('stuTable');
stuTab.deleteRow(oButton.parentNode.parentNode.rowIndex);
}
function submit() {
var myTab = document.getElementById('stuTable');
var arrValues = new Array();
for (row = 1; row < myTab.rows.length - 1; row++) {
for (c = 0; c < myTab.rows[row].cells.length; c++) {
var element = myTab.rows.item(row).cells[c];
if (element.childNodes[0].getAttribute('type') == 'text') {
arrValues.push("'" + element.childNodes[0].value + "'");
}
}
}
var tbodyRef = document.querySelector('#show');
var newRow = tbodyRef.insertRow();
// Insert a cell at the end of the row
arrValues.forEach(item => {
var newCell = newRow.insertCell();
var newText = document.createTextNode(item);
newCell.appendChild(newText);
});

Adding table rows and column dynamically with jQuery

I'm trying to add rows and columns to a table using user input values to determine the number of rows and columns dynamically using jQuery. Below is my code which actually adds rows and columns but not according to the user's inputs
function makeGrid() {
let numOfRow = 0; let numOfCol = 0;
$('#submit').on('click', function() {
numOfRow = $('#height').val();
numOfCol = $('#width').val();
for (var i = 1; i <= numOfRow; i++) {
let row = $('.grid-canvas').append('<tr>');
for (col = 1; col <= numOfCol; col++) {
$('tr').append('<td></td>');
}
}
});
}
makeGrid();
Assuming a user inputs numOfRow = 2 and numOfCol = 2, I should have a table like this
<tbody class="grid-canvas">
<tr>
<td></td>
<td></td>
</tr>
<tr>
<td></td>
<td></td>
</tr>
Problem is my code seems to be adding extra but I haven't been able to figure it out. This is the result of my code
<tbody class="grid-canvas">
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td></td>
<td></td>
</tr>
</tbody>
How do I fix my code?

try changing your code from:
$('#submit').on('click', function() {
numOfRow = $('#height').val();
numOfCol = $('#width').val();
for (var i = 1; i <= numOfRow; i++) {
let row = $('.grid-canvas').append('<tr>');
for (col = 1; col <= numOfCol; col++) {
$('tr').append('<td></td>');
}
}
});
into this
$('#submit').on('click', function() {
numOfRow = $('#height').val();
numOfCol = $('#width').val();
var body = $('.grid-canvas');
for (var i = 1; i <= numOfRow; i++) {
let row = $('<tr></tr>');
for (col = 1; col <= numOfCol; col++) {
row.append('<td></td>');
}
body.append(row);
}
});
what i have done in the above code is created a separate object for the table's body and then once my rows are created with the columns, I append them back to the table object.

Pure javascript code is here
function f(x, y) {
var rows = x,
rowButtonNumber = y;
var table = document.getElementById("myTable");
table.innerHTML = "";
for (var i = 0; i < rows; i++) {
var tr = document.createElement("tr");
table.appendChild(tr);
for (var j = 0; j < rowButtonNumber; j++) {
var td = document.createElement("td");
var btn = document.createElement("button");
btn.innerHTML = "btn " + (i + 1);
btn.id = "btn-" + i;
btn.onclick = function() {
alert(this.innerHTML);
};
td.appendChild(btn);
tr.appendChild(td);
}
}
}
function go() {
var row = document.getElementById("row").value;
var col = document.getElementById("col").value;
f(row, col);
}
<html>
<head>
<style>
td {
width: 200px;
height: 200px;
}
button {
width: 100%;
height: 100%;
}
</style>
</head>
<body>
Rows
<input id="row" type="number" placeholder="Rows" />
<br> Columns
<input id="col" type="number" placeholder="Columns" />
<button onclick="go()">Go</button>
<table id="myTable" cellspacing="50">
</table>
</body>

It does not seem you are using the row variable. I would suggest appending newly created td to row instead of $('tr').

jQuery to JavaScript function

Please someone help me convert this jQuery function into a JavaScript onkeyup or onchange function. I'm always getting an error undefined when I try to alter it as a JavaScript.
Your help will be deeply appreciated.
var inp = $("#txt");
var tbl = document.getElementById("myTable");
// where #txt is the id of the textbox
inp.keyup(function (event) {
if (event.keyCode == 13) {
if (inp.val().length > 0) {
var trow = document.createElement('tr');
var tdata_type = document.createElement('td');
var tdata_code = document.createElement('td');
tdata_type.textContent = $("#select option:selected").text();
tdata_code.textContent = inp.val();
trow.appendChild(tdata_code);
trow.appendChild(tdata_type);
tbl.insertBefore(trow,tbl.firstChild);
}else{
alert("Barcode length insufficient");
}
inp.val('');
}
});
Tried this but I got errors. (index):86 Uncaught ReferenceError: barcode is not defined
at HTMLInputElement.onkeyup
<input type="text" name="yes" id="txt" onkeyup="barcode()">
function barcode(){
var inp = $("#txt");
var tbl = document.getElementById("myTable");
if (event.keyCode == 13) {
if (inp.val().length > 0) {
var trow = document.createElement('tr');
var tdata_type = document.createElement('td');
var tdata_code = document.createElement('td');
tdata_type.textContent = $("#select option:selected").text();
tdata_code.textContent = inp.val();

You have set the LOAD TYPE as onLoad.
So jsfiddle has added a wrapper around your function.
$(window).load(function(){
function barcode() {
}
});
Change the LOAD TYPE to No wrap - in <head>
Updated fiddle

<input type="text" name="yes" onkeyup="barcode()" />
<script>
function barcode( event ) {
if ( event.keyCode == 13 ) {
if ( this.value.length > 0 ) {
var tbl = document.getElementById( 'myTable' ),
trow = document.createElement( 'tr' ),
tdata_type = document.createElement( 'td' ),
tdata_code = document.createElement( 'td' ),
select_el = document.getElementById( 'select' );
tdata_type.innerHTML = select_el.options[ select_el.selectedIndex ].value;
tdata_type.innerHTML = this.value;
trow.appendChild( tdata_code );
trow.appendChild( tdata_type );
tbl.insertBefore( trow, tbl.firstChild );
} else {
alert( 'Barcode length insufficient' );
}
this.value = '';

Datatable not working properly

So I am generating a table with results which are returned from a JSON that is searched through and I would like to table to have pagionation, search, sorting options so I decided to use Data Tables. The table is being generated and populated with the correct results but the sorting options, the search and the pagination options do not appear at all. What am I doing wrong?

I think DataTable is not applying on your table as you are applying datatable on $(document).ready and creating table in your function.
You can apply datatable after you have created the table.
function addTable() {
document.getElementById("results").innerHTML = "";
var myTableDiv = document.getElementById("results")
var tableBody = document.createElement('TBODY')
myTableDiv.border = '1'
myTableDiv.appendChild(tableBody);
var heading = [];
heading[0] = "Бренд"
heading[1] = "Модел"
heading[2] = "Капацитет"
heading[3] = "Коњски сили"
heading[4] = "Цена"
//koloni
var tr = document.createElement('TR');
tableBody.appendChild(tr);
for (a = 0; a < heading.length; a++) {
var th = document.createElement('TH')
th.width = '75';
th.appendChild(document.createTextNode(heading[a]));
tr.appendChild(th);
}
//table rows
for (a = 0; a < finalKola.length; a++) {
var tr = document.createElement('TR');
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].Brand));
tr.appendChild(td);
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].Model));
tr.appendChild(td);
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].engineCap));
tr.appendChild(td);
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].sili));
tr.appendChild(td);
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].amount + " €"));
tr.appendChild(td);
tableBody.appendChild(tr);
}
$('#results').dataTable().fnDestroy();
$('#results').dataTable();
}

Your script is adding tbody before the thead, changed that to append Thead tr first and then tbody.
var selected = [];
var kapacitet = [];
var cena = [];
var hp = [];
var niza = [];
var finalKola = [];
function addTable() {
document.getElementById("results").innerHTML = "";
var myTableDiv = document.getElementById("results")
var tableBody = document.createElement('TBODY')
myTableDiv.border = '1'
var heading = [];
heading[0] = "Бренд"
heading[1] = "Модел"
heading[2] = "Капацитет"
heading[3] = "Коњски сили"
heading[4] = "Цена"
//koloni
var tr = document.createElement('TR');
tableBody.appendChild(tr);
for (a = 0; a < heading.length; a++) {
var th = document.createElement('TH')
th.width = '75';
th.appendChild(document.createTextNode(heading[a]));
tr.appendChild(th);
}
myTableDiv.appendChild(tableBody);
//table rows
for (a = 0; a < finalKola.length; a++) {
var tr = document.createElement('TR');
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].Brand));
tr.appendChild(td);
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].Model));
tr.appendChild(td);
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].engineCap));
tr.appendChild(td);
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].sili));
tr.appendChild(td);
var td = document.createElement('TD')
td.appendChild(document.createTextNode(finalKola[a].amount + " €"));
tr.appendChild(td);
tableBody.appendChild(tr);
}
$(document).ready(function (){

loop through checkbox value to check if its checked

I am working on a thing there a user can input some data, date, activity, and time. And when the user clicks on add, it adds it to a table. This table contains a 4 cell (checkbox) that is checked. Now the point is that a user can add many rows with data and then click on the checkbox, if its unchecked it will not be send to JSON string, but the rows that are checked should be send!
The problem is if i have 1 row thats green and 1 row thats red its still print out all the rows when i click on send greenmarked data.
Below is the code:
<!doctype html>
<html lang="en">
<head>
<style>
table, td {
border: 1px solid black;
padding: 0 40px 0 40px;
}
tr {
background-color: #00FF00;
}
.Green {
background-color: #00FF00;
}
.Red {
background-color: #FF0000;
}
</style>
<meta charset="utf-8">

$check.setAttribute("checked", "true");
$check.setAttribute("id", "checks");
$check.addEventListener("click", toggleClass);
function toggleClass() {
console.log("clicked");
if (this.checked == true)
{
this.parentNode.parentNode.className = "Green";
}
else
{
this.parentNode.parentNode.className = "Red";
}
}
var date = document.getElementById("Datum");
var activity = document.getElementById("Activity");
var time = document.getElementById("time");
var table = document.getElementById("myTable");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML= date.value;
row.insertCell(1).innerHTML= activity.value;
row.insertCell(2).innerHTML= time.value;
row.insertCell(3).appendChild($check).value;
}
function addTable() {

You can find all the checked checkboxes in the table, and then add only the values of rows with a checked checkbox
function AddRow() {
var $check = document.createElement("INPUT");
$check.setAttribute("type", "checkbox");
$check.setAttribute("checked", "true");
$check.setAttribute("class", "checks");
$check.addEventListener("click", toggleClass);
function toggleClass() {
if (this.checked == true) {
this.parentNode.parentNode.className = "Green";
} else {
this.parentNode.parentNode.className = "Red";
}
}
var date = document.getElementById("Datum");
var activity = document.getElementById("Activity");
var time = document.getElementById("time");
var table = document.getElementById("myTable");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML = date.value;
row.insertCell(1).innerHTML = activity.value;
row.insertCell(2).innerHTML = time.value;
row.insertCell(3).appendChild($check).value;
}
function addTable() {
var myTableDiv = document.getElementById("myDynamicTable");
var table = document.createElement('TABLE');
table.border = '1';
var tableBody = document.createElement('TBODY');
table.appendChild(tableBody);
for (var i = 0; i < 3; i++) {
var tr = document.createElement('TR');
tableBody.appendChild(tr);
for (var j = 0; j < 4; j++) {
var td = document.createElement('TD');
td.width = '75';
td.appendChild(document.createTextNode("Cell " + i + "," + j));
tr.appendChild(td);
}
}
myTableDiv.appendChild(table);
}
function CheckData() {
var $arr = [];
var tb = document.getElementById("myTable");
var checks = tb.querySelectorAll(".checks"),
chk, tr;
for (var i = 0; i < checks.length; i++) {
chk = checks[i];
if (chk.checked) {
tr = chk.closest ? chk.closest('tr') : chk.parentNode.parentNode;
$arr.push({
date: tr.cells[0].innerText,
activity: tr.cells[1].innerText
});
}
}
return $arr;
}
function SendData() {
var obj = {
test: CheckData()
};
var jsonString = "jsonString=" + (JSON.stringify(obj));
document.getElementById('jsonString').innerHTML = jsonString;
return; // for testing
var xmlhttp = new XMLHttpRequest();

Since, id of an element must be unique, the id attribute of checkbox is changed to class
