I want to show the data received in my socket event into ajax datatable

I am using socket to receive the json data from my backend. I am receiving the data in the DATA variable and want to iterate it into the ajax datatable. Here is my code.
`
socket.on('getinvoices', (data) => {
var table = $('#table1').DataTable( {
dom: 'Bfrtip',
buttons: [
'copy', 'csv', 'excel', 'pdf', 'print'
],
order: false,
ajax: {
url : "https://testdma.tech-east.com.pk/dma/invoices/getAllInvoices",
dataSrc: "doc",
order: [[0]],
},
columns: [
{ data: 'recipientName' },
{ data: 'recipientAddress' },
{ data: 'recipientPhoneNumber' },
{ data: 'recipientEmail' },
{ data: 'services[/ ].serviceName' },
{ data: 'services[/ ].servicePrice' },
{
data: null,
className: "dt-center editor-delete",
orderable: true,
"mRender" : function ( data, type, row ) {
return '<button class="btn viewbtn" value=' +data._id +'>Edit</button>';
}
},
{
data: null,
className: "dt-center editor-delete",
orderable: true,
"mRender" : function ( data, type, row ) {
return '<button class="btn viewbtn2" value=' +data._id +'>Print Invoice</button>';
}
}
],
});
The data variable on in the socket is where I am receiving my data into.
I tried putting the DATA instead of URL into the ajax datatable but it didnt worked.Kindly guide me how can i populate table with that data

I'm pretty sure to populate a jQuery DataTable with data from a socket event, you can use the ajax.reload() method to update the table's data. Here is an example of how you could do this:
// Define the table
var table = $('#table1').DataTable({
dom: 'Bfrtip',
buttons: [
'copy', 'csv', 'excel', 'pdf', 'print'
],
order: false,
columns: [
{ data: 'recipientName' },
{ data: 'recipientAddress' },
{ data: 'recipientPhoneNumber' },
{ data: 'recipientEmail' },
{ data: 'services[/ ].serviceName' },
{ data: 'services[/ ].servicePrice' },
{
data: null,
className: "dt-center editor-delete",
orderable: true,
"mRender" : function ( data, type, row ) {
return '<button class="btn viewbtn" value=' +data._id +'>Edit</button>';
}
},
{
data: null,
className: "dt-center editor-delete",
orderable: true,
"mRender" : function ( data, type, row ) {
return '<button class="btn viewbtn2" value=' +data._id +'>Print Invoice</button>';
}
}
]
});
// Handle the 'getinvoices' socket event
socket.on('getinvoices', (data) => {
// Update the table data with the data from the socket event
table.ajax.reload(null, false);
});
You can also specify the data source and other options for the table by passing an object to the ajax.reload() method.
table.ajax.reload({
url: "https://testdma.tech-east.com.pk/dma/invoices/getAllInvoices",
dataSrc: "doc",
order: [[0]],
});

column buttons missing from datatables column visibility

We have a datatable that looks like this. As you can see, when you click the column visibility button only a line is appearing:
var dataTableDefaults ={
columnDefs: [
{
"targets": -1,
"orderable": false,
"searchable": false
},
{
"targets": "noSearchOrSort",
"orderable": false,
"searchable": false
},
{
"targets": "noSort",
"orderable": false,
},
{
"targets": "noSearch",
"searchable": false
},
{
"targets": "invisible",
"visible": false
}
],
buttons: [
{
extend : 'colvis',
columns : ":visible"
}
],
order: [[0, 'asc']],
lengthMenu: [[10, 25, 50, 100, -1], [10, 25, 50, 100, "All"]],
language: {
loadingRecords: 'Loading...',
emptyTable: 'No Data available'
},
pagingType: 'full_numbers',
processing: true
};
var cols = [
null,
null,
null,
{ "bVisible" : false }
];
jointDefaults = $.extend(true,{},dataTableDefaults);
jointDefaults.columns = cols
$('#table').DataTable(
$.extend(
jointDefaults,
{
bServerSide: true,
bProcessing: true,
sAjaxSource: 'ajax.php',
fnServerData: function(sSource, aoData, fnCallback) {
aoData.push(
{
name: 'gt',
value: 1
},
{
name: 'mode',
value: pageMode
},
);
$.ajax({
dataType: 'json',
type: 'GET',
url: sSource,
data: aoData,
success: function (response) {
fnCallback(response);
}
});
}
}
)
);
Why are the show/hide buttons on the column visibility not appearing?

How to add Dropdown in JQUERY DataTable?

I want to add Drop down with in a Data Table. But it's not working.
Here I am adding the code I tried:
_dataTables.markAttendanceTable = $('#markAttendanceTable').DataTable(
{
dom: '<"pull-right"f>rt<"bottom"ip><"clear">',
ordering: false,
searching: false,
paging: true,
pageLength: 10,
fixedColumns: false,
data: GetAllMarkAttendance(eventId),
language: {
search: "_INPUT_",
searchPlaceholder: "Search"
},
columns: [
{ "data": "Login.Name", "defaultContent": "<i>-</i>" },
{"data":null ,
render: function (d, t, r) {
debugger;
var $select = $("<select></select>", {
//"id": //r[0]+"start",
"id": "Select",
"value": "Select"
});
$.each(attended, function(k,v){
var $option = $("<option></option>", {
"text": v,
"value": k
});
if(d === v){
$option.attr("selected", "selected")
}
$select.append($option);
});
return $select.prop("outerHTML");
}
},
],
columnDefs: [
{ className: "text-left", "targets": [0] },
{ className: "text-center", "targets": [] },
//{ width: "30%", "targets": [0] },
//{ width: "25%", "targets": [1] },
],
});
Please give me your suggestions.

Reset Count using Data Tables on draw

I am currently using Data Tables. I have two tables that Add and Remove data from one table to another. I have a count at the moment that is working somewhat, but when the table draws from one table to another the count is not being reset. It also seems to happen when moving pagination. Is there a way I can get JQuery to set a dynamic id.
Currently, this is what I have:
var selectedContractsTable = $('#catalogueLinkedContractsTable').DataTable({
sAjaxSource: linkedUrl,
columns: [
{ "data": "ID" },
{ "data": "Selected"},
{ "data": "Name"},
{ "data": "ContractType"},
{ "data": "StartDate"},
{ "data": "TerminationDate"},
{ "button": "Action" }
],
serverSide: false,
sDom: 't<"dt-panelfooter clearfix"ip>',
pageLength: pageSize,
bSort: false,
bLengthChange: false,
bSearch: true,
paging: true,
searching: true,
order: [[2, "asc"]],
language: {
emptyTable: "No linked contracts found.",
zeroRecords: "No linked contracts found.",
info: "_START_ to _END_ of _TOTAL_",
paginate: {
first: "First",
previous: "Previous",
next: "Next",
last: "Last"
}
},
columnDefs: [
{
targets: [0],
visible: false
},
{
targets: [1],
visible: false
},
{
targets: [3],
sClass: "hidden-xs hidden-sm contractType"
},
{
targets: [4],
sClass: "hidden-xs fromDate"
},
{
targets: [5],
sClass: "hidden-xs terminationDate"
},
{
data: null,
targets: [6],
sClass: "updateTableRow text-center",
render: function ( data, type, full, meta )
{
var id = data["ID"];
// id number added for testing purposes
var removebuttonData = `<button class=\"btn btn-danger br2 btn-xs fs12 table-btn button-selector-${id}\" id=\"RemoveContractBtn_` + count + `\">Remove</button>`;
count++;
return removebuttonData;
}
}
],
autoWidth: false
});
#* Setup the (Non-Selected) Contracts table (data, search, paging handled server side) *#
count = 0;
var url = "/ClientSetup/GetCatalogueContracts";
var contractsTable = $('#catalogueContractsTable').DataTable({

Found that I could use meta.row
Which was in the documentation: https://datatables.net/reference/option/columns.render

Problems displaying array data for datatables

I'm having problems display data in datatables, if I put the array straight in like this it works
$.parseJSON("[[\"1\",\"New Zealand\",\"20\"],[\"2\",\"Australia\",\"30\"]]");
but when I do it using a variable it doesn't it says read the error docs https://datatables.net/manual/tech-notes/4
I don't understand what's going on here
var self = this;
var data = $.parseJSON(self.model.get('shipping'));
// data is in this format [["1","New Zealand","20"],["2","Australia","30"]]
var intfreight = $('#edit-int-freight').DataTable(
{
//"aoColumnDefs": [{ "aTargets": [ 2 ] }] ,
'columnDefs': [
{
"targets": [ 0 ],
"visible": false,
"searchable": false
}
],
data: data,
columns: [
{ title: 'id' },
{ title: 'country', searchable: true},
{ title: 'shipping_rate',
render: function (data, type, row) {
return '$' + data;
}},
{ title: 'action', orderable: false, searchable: false, render: function() {
return '<a class="delete" href="#edit/delete-freight">Delete</a>';
}}
]
});
