How can have multirows Footer in Datatables?

I want make two rows at my footer datatables. First row of footer for sum columns and second row of footer for search columns.
This is my code in javascript
$(function () {
$('#ntable1 tfoot th').each( function () { //for search columns in footer
var title = $(this).text();
$(this).html( '<input type="text" placeholder="'+title+'"/>' );
} );
var table = $("#ntable1").DataTable({
"responsive": false, "scrollX": true, "lengthChange": true, "autoWidth": false,
"buttons": [
{
extend: 'copy',
exportOptions: {
columns: [':visible' ]
}
},
{
extend: 'excel',
exportOptions: {
columns: [':visible' ]
},
messageBottom: textTop,
},
{
extend: 'print',
footer: true,
exportOptions: {
columns: [':visible' ]
},
messageTop: textTop
},
{
extend: 'colvis',
exportOptions: {
columns: [':visible' ]
}
}
],
footerCallback: function (row, data, start, end, display) { //for sum of columns in footer
var api = this.api();
// Remove the formatting to get integer data for summation
var intVal = function (i) {
return typeof i === 'string' ? i.replace(/[\$,]/g, '') * 1 : typeof i === 'number' ? i : 0;
};
// Total over all pages
total = api
.column(3)
.data()
.reduce(function (a, b) {
return intVal(a) + intVal(b);
}, 0);
// Total over this page
pageTotal = api
.column(3, { page: 'current' })
.data()
.reduce(function (a, b) {
return intVal(a) + intVal(b);
}, 0);
// Update footer
$('tr:eq(0) td:eq(3)', api.table().footer()).html(format('$' + pageTotal + ' ( $' + total + ' total)')); //not work
// $(api.column(3).footer()).html('$' + pageTotal + ' ( $' + total + ' total)'); //not work
},
initComplete: function () {
// Apply the search
this.api().columns().every( function () {
var that = this;
$( 'input', this.footer() ).on( 'keyup change clear', function () {
if ( that.search() !== this.value ) {
that
.search( this.value )
.draw();
}
} );
} );
}
}).buttons().container().appendTo('#ntable1_wrapper .col-md-6:eq(0)');
});

</tr>
</tfoot>
</table>
If I add row in footer, my search column doesn't work. My problem only how to have multiple rows in footer datatables, which first row for calculate sum and second row for search column. Hope anyone can help.

How to create nested datatable from JSON array object response

I get API response in JSON format with nested arrays in it. I want to parse it in nested datatable. I've tried for this, but it won't work. Can anyone let me know where I made a mistake. In JSON I have passenger data & each passenger having multiple drivers, I want to show it in datatable in nested format, like Passenger is parent & respective drivers of it as child.
Expected Result
Here is my JSON response:
/* Formatting function for row details - modify as you need */
function format(driver_data) {
// `d` is the original data object for the row
return '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">' +
'<tr>' +
'<td>Full name:</td>' +
'<td>' + driver_data.employeename + '</td>' +
'</tr>' +
'<tr>' +
'<td>Extension number:</td>' +
'<td>' + driver_data.email + '</td>' +
'</tr>' +
'</table>';
}
$(document).ready(function () {
var table = $('.trip_unmacthed').DataTable({
type: "GET",
url: "https://api.myjson.com/bins/13woes",
dataType: "json",
"columns": [
{
"className": 'details-control',
"orderable": false,
"data": null,
"defaultContent": ''
},
{
"data": "employeename"
},
{
"data": "email"
}
],
"order": [[1, 'asc']]
});
// Add event listener for opening and closing details
$('.trip_unmacthed tbody').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var row = table.row(tr);
if (row.child.isShown()) {
// This row is already open - close it
row.child.hide();
tr.removeClass('shown');
} else {
// Open this row
row.child(format(row.data())).show();
tr.addClass('shown');
}
});
});
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script src="https://cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js"></script>
<table class="table table-striped table-bordered table-hover trip_unmacthed">
<thead>
<tr>
<th>User Type</th>
<th> Name</th>
<th>Start Location</th>
<th>Drop Location</th>
<th> Date </th>
<th>Actions</th>
</tr>
</thead>
<tbody id="myData">
</tbody>
</table>

Change the passenger_data to data according to API Docs and your format function.
$(document).ready(function () {
function format(driver_data) {
console.log(driver_data); var b = ''; var i;
for (i = 0; i < driver_data.length; i++) {
b = b + '<tr>' +
'<td></td>' +
'<td>' + driver_data[i].employeename + '</td>' +
'<td>' + driver_data[i].email + '</td>' +
'<td>' + driver_data[i].distance + '</td>' +
'</tr>';
}
return b;
}
var table = $('#example').DataTable({
"ajax": "https://api.myjson.com/bins/y53hs",
"columns": [
{
"className": 'details-control',
"orderable": false,
"data": null,
"defaultContent": ''
},
{
"data": "employeename"
},
{
"data": "email"
},
{
"data": "mobilenumber"
}
],
"order": [[1, 'asc']]
});
// Add event listener for opening and closing details
$('#example tbody').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var row = table.row(tr);
if (row.child.isShown()) {
// This row is already open - close it
row.child.hide();
tr.removeClass('shown');
} else {
// Open this row
console.log(row.data());
row.child(format(row.data().driver_data)).show();
tr.addClass('shown');
}
});
});

Not sure about what your JSON is . If you have a passenger in your JSON e.g.
{
"passenger_data": [
{
"employeename": "Passenger A",
"email": null,
"driver_data": [
{
"employeename": "Driver A1",
"email": null,
"distance": 0,
},
{
"employeename": "Driver A2",
"email": null,
"distance": 0,
},
],
"mobilenumber": "+12344576",
},
]
}
then you should do it like
"columns": [
{"passenger_data": "employeename"},
{"passenger_data": "driver_data.employeename"},
{"passenger_data": "driver_data.email"}
],
may be your are not using the . operator

unable to display sum in footer using datatable

I have created a datatable using jQuery. The table has seven columns , among one column is for Grand Total (column 6). I have to display the sum of Grand Total (column 6) in the Grand Total (column 6) at the bottom of Grand Total (column 6).
How can I do that? I have tried some code but nothing worked.
Outout is blank column.
here is the code that I found.
below is the html code
HTML
<table class="display table table-bordered table-striped" id="dynamic-table">
<thead>
<tr>
<th>Invoice Type</th>
<th>Invoice No</th>
<th>Invoice Date</th>
<th>Customer Name</th>
<th>City </th>
<th>Grand Total</th>
<th class="hidden-phone">Action</th>
</tr>
</thead>
<tbody>
</tbody>
<tfoot>
<tr>
<th></th>
<th></th>
<th></th>
<th></th>
<th>Total:</th>
<th></th>
<th></th>
</tr>
</tfoot>
</table>
JavaScript
function load_datatable() {
var data = $('input[name=report]:Checked').val();
var date = $('#rep_date').val();
var type = $('#type_id').val();
datatable = $("#dynamic-table").dataTable({
"bAutoWidth": false,
"bFilter": true,
"bSort": true,
"bProcessing": true,
"bDestroy": true,
"bServerSide": true,
"oLanguage": {
"sLengthMenu": "_MENU_",
"sProcessing": "<img src='" + root_domain + "img/loading.gif'/> Loading ...",
"sEmptyTable": "NO DATA ADDED YET !",
},
"aLengthMenu": [
[10, 20, 30, 50],
[10, 20, 30, 50]
],
"iDisplayLength": 10,
"sAjaxSource": root_domain + 'app/invoice/',
"fnServerParams": function(aoData) {
aoData.push({
"name": "mode",
"value": "fetch"
}, {
"name": "report",
"value": data
}, {
"name": "type_id",
"value": type
}, {
"name": "date",
"value": date
});
},
"footerCallback": function(row, data, start, end, display) {
var api = this.api(),
data;
// Remove the formatting to get integer data for summation
var intVal = function(i) {
return typeof i === 'string' ?
i.replace(/[\$,]/g, '') * 1 :
typeof i === 'number' ?
i : 0;
};
// Total over this page
pageTotal = api
.column(5, {
page: 'current'
})
.data()
.reduce(function(a, b) {
return intVal(a) + intVal(b);
}, 0);
console.log(pageTotal);
// Update footer
$(api.column(5).footer()).html('$' + pageTotal);
},
"fnDrawCallback": function(oSettings) {
$('.ttip, [data-toggle="tooltip"]').tooltip();
}
}).fnSetFilteringDelay();
//Search input style
$('.dataTables_filter input').addClass('form-control').attr('placeholder', 'Search');
$('.dataTables_length select').addClass('form-control');
}

do this example :
const Table = $('#foo').DataTable({
. . . . . .,
. . . . . .,
drawCallback: function(){
Table.columns(5, {
page: 'current'
}).every(function() {
var sum = this
.data()
.reduce(function(a, b) {
var x = parseFloat(a) || 0;
var y = parseFloat(b) || 0;
return x + y;
}, 0);
console.log(sum);
$(this.footer()).html(sum);
});
}
});
in this case the column was column number 5

How to search child row content

I would like this demo to work with the filter, not removing entries whose children have the data that you are filtering for.
E.g. in the example if you filter for 5407 Airi Satou does not get deleted and maybe even the child data gets expanded.
HTML and JS
/* Formatting function for row details - modify as you need */
function format ( d ) {
// `d` is the original data object for the row
return '<div class="slider">'+
'<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+
'<tr>'+
'<td>Full name:</td>'+
'<td>'+d.name+'</td>'+
'</tr>'+
'<tr>'+
'<td>Extension number:</td>'+
'<td>'+d.extn+'</td>'+
'</tr>'+
'<tr>'+
'<td>Extra info:</td>'+
'<td>And any further details here (images etc)...</td>'+
'</tr>'+
'</table>'+
'</div>';
}
$(document).ready(function() {
var table = $('#example').DataTable( {
"ajax": "/examples/ajax/data/objects.txt",
"columns": [
{
"class": 'details-control',
"orderable": false,
"data": null,
"defaultContent": ''
},
{ "data": "name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "salary" }
],
"order": [[1, 'asc']]
} );
// Add event listener for opening and closing details
$('#example tbody').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var row = table.row( tr );
if ( row.child.isShown() ) {
// This row is already open - close it
$('div.slider', row.child()).slideUp( function () {
row.child.hide();
tr.removeClass('shown');
} );
}
else {
// Open this row
row.child( format(row.data()), 'no-padding' ).show();
tr.addClass('shown');
$('div.slider', row.child()).slideDown();
}
} );
} );
CSS
td.details-control {
background: url('/examples/resources/details_open.png') no-repeat center center;
cursor: pointer;
}
tr.shown td.details-control {
background: url('/examples/resources/details_close.png') no-repeat center center;
}
div.slider {
display: none;
}
table.dataTable tbody td.no-padding {
padding: 0;
}

SOLUTION
In order for jQuery DataTables to search child rows you need to add data displayed in the child rows to the main table as hidden columns.
For example, you can add hidden column for extn data property using columns.visible option as shown below:
JavaScript:
"columns": [
{
"class": 'details-control',
"orderable": false,
"data": null,
"defaultContent": ''
},
{ "data": "name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "salary" },
{ "data": "extn", "visible": false }
],
HTML:
<thead>
<tr>
<th></th>
<th>Name</th>
<th>Position</th>
<th>Office</th>
<th>Salary</th>
<th>Extn.</th>
</tr>
</thead>

See this jsFiddle for code and demonstration.

how to get the inner html value from Datatable cell

I am newbie to DataTable. here I am trying to get the of first cell value of a row when I click the viewlink associated with the row, instead of the value I am getting [object object].
heres my code
$(document).ready(function() {
// Delete a record
$('#example').on('click', 'a.editor_view', function (e) {
e.preventDefault();
var rowIndex = oTable.fnGetPosition( $(this).closest('tr')[0] );
aData = oTable.fnGetData($(this).parents('tr')[0]);
alert(aData);
} );
// DataTables init
var oTable=$('#example').dataTable( {
"sDom": "Tfrtip",
"sAjaxSource": "php/browsers.php",
"aoColumns": [
{ "mData": "browser" },
{ "mData": "engine" },
{ "mData": "platform" },
{ "mData": "grade", "sClass": "center" },
{
"mData": null,
"sClass": "center",
"sDefaultContent": 'view / Delete'
}
]
} );
} );
HTML Table:
<table cellpadding="0" cellspacing="0" border="0" class="display" id="example" width="100%">
<thead>
<tr>
<th width="30%">Browser</th>
<th width="20%">Rendering engine</th>
<th width="20%">Platform(s)</th>
<th width="14%">CSS grade</th>
<th width="16%">Admin</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Browser</th>
<th>Rendering engine</th>
<th>Platform(s)</th>
<th>CSS grade</th>
<th>Admin</th>
</tr>
</tfoot>
Now when I Click on the view I need to Navigate to another page with the id like
view.php?id=125
Thank you

$('#example').on('click', 'a.editor_view', function (e) {
e.preventDefault();
var rowIndex = oTable.fnGetPosition( $(this).closest('tr')[0] );
aData = oTable.fnGetData(rowIndex,0);
alert(aData);
} );
From the api docs:
fnGetData
Input parameters:
{int|node}: A TR row node, TD/TH cell node or an integer. If given as a TR node then the data source for the whole row will be returned. If given as a TD/TH cell node then iCol will be automatically calculated and the data for the cell returned. If given as an integer, then this is treated as the aoData internal data index for the row (see fnGetPosition) and the data for that row used.
{int}: Optional column index that you want the data of.

Assuming your first row is your id, would you want to include the links in your dataTable initializer like this?
$(document).ready(function () {
var oTable = $('#example').dataTable({
"aoColumnDefs": [{
"fnRender": function (oObj) {
var id = oObj.aData[0];
var links = [
'View',
'Delete'];
return links.join(' / ');
},
"sClass": "center",
"aTargets": [4]
}, {
"sClass": "center",
"aTargets": [3]
}]
});
});
