Rows are added in thead instead of tbody

The following HTML file contains an add button. When clicked, it should add a row. When I inspect the code, I find the rows added under the thead not the tbody tag. Why is that? how to avoid this?
addButton = document.getElementById("add-button");
table = document.getElementById("data-table");
addButton.addEventListener('click', add, false);
function add() {
var tableLength = table.length;
var row = table.insertRow(tableLength);
var col1 = row.insertCell(0);
var col2 = row.insertCell(1);
col1.innerHTML = "col1";
col2.innerHTML = "col2";
}
var delLink = document.getElementById("delete-link");
delLink.addEventListener('click', del, false);
function del() {
var rowstoDelete = table.querySelectorAll("tbody tr");
[].slice.call(rowstoDelete).forEach(function(row) {
row.remove()
});
}
<table align="center" cellspacing=1 cellpadding=1 id="data-table" border=1 class="data-table">
<thead>
<tr id="head" class="head">

How to use jquery autocomplete in dynamically form input

I'm having an issue using jQuery autocomplete with dynamically created inputs. I can't get autocomplete to bind to the new inputs.

// membuat aksi delete element
hapus.onclick = function () {
row.parentNode.removeChild(row);
};
i++;
}
</script>
Any advice?

You can use JS Math functions to create a random and unique id.. then you will need to call the autocomplete inside the function. Just repeat this process for each of your autocomplete methods.
var namaid = 'nama' + (Math.floor((1 + Math.random()) * 0x10000));
nama_input.setAttribute('id', namaid);
$("#" + namaid).autocomplete({
source: "get_barang.php",
minLength: 2,
select: function(event, ui) {
$('#kode').val(ui.item.kode);
$('#harga').val(ui.item.harga);
}
});
Handy tip: Since you're using jQuery, you can create elements with jQuery a lot easier than in vanilla JS.. have a look at this.

Jquery - add new rows table into wrong div

I am pretty new to jquery. I have the following code. Here I wants to get new rows in the table on clicking add button in Fill 3. I succeend to add that row, but when I get new divs then I wants to get new rows in the table on clicking add button in Fill 3. It added into wrong div.
can someone tell me what mistake I've done here?
var id = 0; //global id to create unique id
$(document).ready(function() {
//attach click event to element/button with id add and remove
$("#add,#remove").on('click', function() {
var currentElemID = $(this).attr('id'); //get the element clicked
if (currentElemID == "add") { //if it is add elem
var cloneParent = $("#dataTes").clone(); //clone the dataTes element
id=$("div[id^=dataTes]").length + 1;//get the count of dataTes element
//it will be always more than last count each time
cloneParent.find('[id]').each(function() {
//loop through each element which has id attribute in cloned set and replace them
//with incremented value
var $el = $(this); //get the element
$el.attr('id', $el.attr('id') + id);
//ids would now be add1,add2 etc.,
});
cloneParent.attr('id', cloneParent.attr('id') + id);//replace cloneParent id
cloneParent.appendTo('#result');//append the element to fieldset
$("#remove").show();//show remove button only if there is more than one dataTes element
} else {
$("div[id^=dataTes]:last").remove();
//just remove the last dataTes
//[id^=dataTes]:last annotates remove last div whose id begins with dataTes
//remember we have id like dataTes1,dataTes2 etc
if($("div[id^=dataTes]").length==1){
//check if only one element is present
$("#remove").hide();//if yes hide the remove button
}
}
});
});
function addRow(tableID) {
var table = document.getElementById(tableID);

Thanks in advance!

<input type="submit" class="button" value="-" onClick="deleteRow('dataIP')" title = "#">
</td>
</tr>
</table>`
so what will we do here is that we will change addRow(this) instead of addRow('dataIp') because we know that "this" keyword has a high priority in terms of passing the ID of the element .. the "this" keyword has a general purpose vs passing of id into a function .. just try changing all parameter to the "this".

function addRow(tableID) {
var par = tableID.parentNode.parentNode.parentNode.id;
var table = document.getElementById(par);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for (var i = 0; i < colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[0].cells[i].innerHTML;
}
this is what ive done when I change the parameter of the add and delete function in your input i get the param parent node the element for the purpose of specific element inside the parent element...
}

by the way.. you must change your third index table to tbody. the result of getting the parentnode will be a tbody. because putting table inside a table is redundant window read it as tbody
we must follow the rule
<table>
<tbody>
</tbody>
<tfoot>
</tfoot>
</table>

Creating 2 html tables using javascript

I'm trying to create 2 dynamic html tables using Javascript with data from html inputs. I was able to create the first table I wanted but I've been unable to create 2 different tables using different inputs on the same page.
I tried changing the addRow() functions in the html and JS to have different names but this caused both tables to fail.
Any help would be appreciated. Here's the test code I've been using.
<!DOCTYPE html>
<body onload="load()">
<div id="myform">
<table>
<tr>
<td>Name:</td>
<td><input type="text" id="name"></td>
</tr>
<tr>
<td>Age:</td>
<td><input type="number" id="age">
<input type="button" id="add" value="Add" onclick="addRow()"></td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
</table>
<br>
<table>
<tr>
<td>Height:</td>
<td><input type="text" id="height"></td>
</tr>
<tr>
<td>Width:</td>
<td><input type="text" id="width">
<input type="button" id="addDim" value="Add" onclick="addRow()"></td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
</table>
</div>
<div id="mydata">
<table id="myTableData" border="1" cellpadding="2">
<tr>
<td> </td>
<td><b>Name</b></td>
<td><b>Age</b></td>
</tr>
</table>
<table id="myTableData2" border="1" cellpadding="2">
<tr>
<td> </td>
<td><b>Height</b></td>
<td><b>Width</b></td>
</tr>
</table>
</body>
</html>
function addRow() {
var myName = document.getElementById("name");
var age = document.getElementById("age");
var table = document.getElementById("myTableData");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML= '<input type="button" value = "Delete" onClick="deleteRow(this)">';
row.insertCell(1).innerHTML= myName.value;
row.insertCell(2).innerHTML= age.value;
var width = document.getElementById("width");
var height = document.getElementById("height");
var table2 = document.getElementById("myTableData2");
var rowCount2 = table2.rows.length;
var row2 = table2.insertRow(rowCount2);
row.insertCell(0).innerHTML = '<input type="button" value="Delete" onClick="deleteRow(this)">';
row.insertCell(1).innerHTML = width.value;
row.insertCell(2).innerHTML = height.value;
}
function deleteRow(obj) {
var index = obj.parentNode.parentNode.rowIndex;
var table = document.getElementById("myTableData");
table.deleteRow(index);
}
function load() {
console.log("Page load finished");
}

Looks like in the bottom section, you're not using the row2 variable you've defined.
Should be:
var rowCount2 = table2.rows.length;
var row2 = table2.insertRow(rowCount2);
row2.insertCell(0).innerHTML = '<input type="button" value="Delete" onClick="deleteRow(this)">';
row2.insertCell(1).innerHTML = width.value;
row2.insertCell(2).innerHTML = height.value;

here how i did it. you can use the same function for any amount of table, if pass the parameter in the function.
http://jsfiddle.net/8t5aqomk/2/
function myFunction(thisTable) {
var firstName = document.getElementById('firstName').value;
var lastName = document.getElementById('lastName').value;
var age = document.getElementById('age').value;
var info = [firstName,lastName,age]
var table = document.getElementById(thisTable);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cellCount = table.rows[0].cells.length;
for(var i=0; i<cellCount; i++) {
row.insertCell(i).innerHTML=info[i];
}
}

How to insert a row in an HTML table body in JavaScript

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>
JavaScript file:
$.ajax({
type: "POST",
contentType: "application/json",
url: "/search",
data: JSON.stringify(search),
dataType: 'json',
cache: false,
timeout: 600000,
success: function (data) {
// var json = "<h4>Ajax Response</h4><pre>" + JSON.stringify(data, null, 4) + "</pre>";
// $('#feedback').html(json);
//
console.log("SUCCESS: ", data);
//$("#btn-search").prop("disabled", false);
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></tr>');
$('#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>";
$('#feedback').html(json);
console.log("ERROR: ", e);
$("#btn-search").prop("disabled", false);
}
