How to create jQuery datatable with multiple child rows(nested table)? - json

Question

Question:
I need to create a table with a nested table format. When a user clicks plus button it should show the nested table. If they click minus button it should hide.
I have done jquery datatable its working fine. but I'm not able to display multiple rows for child table. I have tried so many times I'm not able to display proper format.
This is the link I have referred to create a table
https://datatables.net/examples/api/row_details.html
Database:
Actual data coming from the database as per the below format and I have converted JSON format to display :
C# Code:
return new JsonResult { Data = new { data = test }, JsonRequestBehavior =
JsonRequestBehavior.AllowGet };
I need an output like this with a nested table:
UI CODE:
/* Formatting function for row details - modify as you need */
function format ( d ) {
// `d` is the original data object for the row
return '<table cellpadding="5" cellspacing="0" border="0" style="padding-
left:50px;">'+
'<tr>' +
'<td>City Name</td>' +
'<td>Permission</td>' +
'</tr><tr>' +
'<td>' + d.City+ '</td>' +
'<td>' + d.Permission+ '</td>' +
'</tr>' +
'</table>';
}
$(document).ready(function() {
var table = $('#example').DataTable( {
"ajax": "../ajax/data/objects.txt",
"columns": [
{
"className": 'details-control',
"orderable": false,
"data": null,
"defaultContent": ''
},
{ "data": "UserName" },
{ "data": "Email" },
{ "data": "UserId" },
],
"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
row.child( format(row.data()) ).show();
tr.addClass('shown');
}
} );
} );
JSON FORMAT:
{"data":[
{"UserId":"ABC","UserName":"Peter","Email":"abc#gmail.com.com","CityName":"Chennai","Permission":"Manager,LocalUser"},
{"UserId":"ABC","UserName":"Peter","Email":"abc#gmail.com.com","CityName":"Bangalore","Permission":"Admin,LocalUser"},
{"UserId":"xyz","UserName":"Haiyan","Email":"abc2#gmail.com.com","CityName":"Bangalore","Permission":"LocalUser"},
{"UserId":"xyz","UserName":"Haiyan","Email":"abc2#gmail.com.com","CityName":"Chennai","Permission":"LocalUser,Manager"}]}
Technology used: ASP.Net MVC5
Any other way I'm ready to use either linq or modify JSON data format.

Answer 1

You can give Id to your child table like this
function format ( d ) {
// `d` is the original data object for the row
return '<table id="childtable" cellpadding="5" cellspacing="0" border="0" style="padding-
left:50px;">'+
'<tr>' +
'<td>City Name</td>' +
'<td>Permission</td>' +
'</tr><tr>' +
'<td>' + d.City+ '</td>' +
'<td>' + d.Permission+ '</td>' +
'</tr>' +
'</table>';
}
and do the same thing which you did for your parent table
var childTable = $('#childtable').DataTable( {
"ajax": "../ajax/data/objects.txt",
"columns": [
],
"order": [[1, 'asc']]
} );
bind your json object in columns section.
