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?
This question is related to

row
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)
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);
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;

</html>And cells.
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;
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);
}
});
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.
