I'm using DataTables to fill a table and need some data from a different source. So I started off with render and made a second ajax request by the ID's of what I need the name of.
Here is my code, that will explain it more clearly.
$('#table').DataTable({
"ajax": "/api/url",
"language": {
"url": "//cdn.datatables.net/plug-ins/9dcbecd42ad/i18n/German.json"
},
"order": [[0, "asc"]],
"pagingType": "simple",
"responsive": {details: false},
"bAutoWidth": true,
"lengthChange": true,
"scrollX": false,
"aoColumnDefs": [{}],
"columns": [
{
"data": "typ_name"
},
{
"data": "mietpreise",
render: function (data, type, row, meta) {
let tmp = [],
currentCell = $("#table").DataTable().cells({
"row": meta.row,
"column": meta.col
}).nodes(0);
data.forEach(function (item) {
$.get("/api/url2/" + item.preis_kundengruppe_id, function (row, status) {
tmp.push(row.data.kundengruppe_name);
});
});
console.log(tmp);
return $(currentCell).text(tmp);
}
},
I'm expecting to have the value of kundengruppe_name in the array like ['case1', 'case2'] but in the console I get this
[]
0: "Endkunden"
1: "Händler"
length: 2
__proto__: Array(0)
So what I want is to find under 0 and 1 and not in the array as expected. What am I doing wrong? What's going on with the array?

I am trying to add a select dropdown to each of my rows in a dataTable from datables version 1.10.23. Both my table data and select data is coming from an API that returns JSON. I have a separate funtion that gets the select data, builds the selected element in JS and returns the whole element. Normally I can append this to a div no problem, but when trying to add to my data tabel I get: [object HTMLSelectElement] in my table instead of the actual select element.
Code:
async function buildRentalReturnTable() {
// table data
let rentalData = await getRentalDetails();
if ($.fn.DataTable.isDataTable('#rentalReturnTable')) {
$('#rentalReturnTable').DataTable().destroy();
}
// returns whole selected element with options populated from API
let selectElement = await buildStatusDDL();
$("#rentalReturnTable").DataTable({
"destroy": true,
"data": rentalData,
"dom": '<"top"i<"clear">><"top d-flex justify-content-between pt-1"lf>rt<"bottom pt-2"p>',
"fixedHeader": true,
"scrollY": "50vh",
"scrollCollapse": true,
"oLanguage": {
"sEmptyTable": "No results found",
"sSearch": "Filter Results:"
},
"columnDefs": [{
"targets": 0,
"orderable": false
}],
"order": [[1, 'asc']],
"columns": [
{
"data": function (data) {
return selectElement
}, "title": "Status"
},
{ "data": "RentalLPID", "title": "RentalLPID" },
{ "data": "SKU", "title": "SKU" },
{ "data": "Description1", "title": "Description1" },
{ "data": "NextRentalDate", "title": "NextRentalDate" },
],
"pagingType": "full_numbers",
"lengthMenu": [
[10, 25, 50, -1],
[10, 25, 50, "All"]
],
responsive: true
});
}
UI example
Any suggestions?
You need the text (string) of the HTML element - not the element itself (which is an object). Try:
return selectElement.outerHTML
See here for documentation.
I have been trying to render my json in datatable. The json format i have been working with is as follows:
{
message: "",
data: {
count: "",
result: [
{
parameter1: "",
parameter2: "",
parameter3: "",
},
{
parameter1: "",
parameter2: "",
parameter3: "",
},
]
}
}
Datatable Code is as follow
$('#example').DataTable({
"processing": true,
"serverSide": true,
"ajax": {
url: "https://c22c6e75-a9b9-4762-8f5d-b25137536fa6.mock.pstmn.io/iprSearchData",
},
"columnDefs": [
{
"targets": [0],
"data": function (row, type, val, meta) {
// not hitting
console.log(row);
console.log(type);
console.log(val);
console.log(meta);
},
"render": function (data, type, row) {
console.log(data);
console.log(row);
return data;
},
},
// {targets: [0], visible: true},
// {targets: '_all', visible: false}
]
});
I read the documentation and I assume the data(JSON) format is creating problems for me in rendering or is it some other issue?
I want to render my parameters in reult array of the JSON to be displayed in a single column.
Thanks in advance.
The JSON format was the issue. Use datasrc in ajax for appropriate data from the returned ajax.
i created a table with jquery datatables. when I want to filter my table with search bar, the browser gives me an alert DataTables warning: table id=grid - Ajax error. For more information about this error, please see http://datatables.net/tn/7.
this is my code :
$("#grid").dataTable({
"processing": true, // control the processing indicator.
"serverSide": true, // recommended to use serverSide when data is more than 10000 rows for performance reasons
"info": true, // control table information display field
"stateSave": true, //restore table state on page reload,
"searching": true,
"language": {
"url": "/translate/datatables.fa-IR.json"
},
"lengthMenu": [[10, 20, 50, -1], [10, 20, 50, "All"]], // use the first inner array as the page length values and the second inner array as the displayed options
"ajax": {
"url": serviceBase + "/Auth/Admin/SearchOrders2/",
"type": "GET",
'beforeSend': function (xhr) {
xhr.setRequestHeader("Authorization", "Bearer " + localStorageService.get("authorizationData").token);
}
},
"columns": [
{ "data": "customerContact", "orderable": true },
{ "data": "isDone", "orderable": true },
{
"mRender":
function (data, type, row) {
var xxx = $scope.name1 = $filter("jalaliDateFromNow")(row["createdDate"]);
return "<span>" + $filter("jalaliDateFromNow")(row["orderCreationTime"]); +'</span>';
}, "orderable": true
},
{ "data": "totalPrice", "orderable": true },
{ "data": "count", "orderable": true },
{ "data": "description", "orderable": true },
{
"mRender": function (data, type, row) {
return '<button class="btn btn-sm btn-circle green tooltips" disabled="disabled"><i class="fa fa-check"></i><span>جزئیات</span></button>'
},
"orderable": false
}
],
"order": [[0, "desc"]]
});
which part of my code is wrong?
I'm using jquery data table to display large amounts of data inside grid. I implemented server side pagination but I'm struggling with sorting data server side.
Below is my datatable initialization, answer with query for sorting is not the subject here, I just need a way to pass information of which column is clicked to the controller, the one upon I will do the sorting.
('#myTable').dataTable({
"processing": true,
"serverSide": true,
"info": false,
"pageLength": 10,
"lengthChange": false,
"stateSave": false,
"bPaginate": true,
"bFilter": false,
"sPaginationType": "full_numbers",
"info": "Page _PAGE_ from _PAGES_",
"infoEmpty": "No data",
"oPaginate": {
"sFirst": "First",
"sPrevious": "Previous",
"sNext": "Next",
"sLast": "Last"
},
"ajax": {
"url": "#string.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Authority, Url.Content("~"))/MyController/GetData",
"type": "GET",
"data": function (d) {
.....
},
},
preDrawCallback: function (settings) {
...
},
drawCallback: function (settings) {
...
},
"columns": [
{ "data": "Id" },
{ "data": "FirstName" },
{ "data": "LastName" },
{ "data": "Age" }
],
"columnDefs": [
{
targets: [0],
orderable: false
},
{
render: function (data, type, row) {
...
}
],
"order": [[0, "desc"]]
});
public ActionResult GetData(){
var sortColumn = ...
...
}
You can bind the 'order' event like this:
$('#myTable').on( 'order.dt', function () {
var order = table.order();
var column_selected = order[0][0];
var order_way= order[0][1];
doStuff(column_selected ,order_way);
});
See it in plugin reference
By specifying "serverSide": true,, datatables will by default add information to the request which you need to use in your server-side code. If you look in the Firebug Network panel, you will be able to see the request with the querystring parameters. See here for the full list of parameters. Note that the link is to the v1.9 documentation, because that's what it looks like you're using.
So for sorting, you'd be interested in iSortCol_0 and sSortDir_0 which relate to the clicked column and the sort direction respectively.
In your controller method, you would access the parameters like this:
var sortColumnIndex = Convert.ToInt32(Request["iSortCol_0"]);
var sortColumnDir = Request["sSortDir_0"];
You then need to incorporate this, and the other parameters into your query.
Here is an article on using server-side datatables with MVC
I am using jquery datatables.net and I have a table with information. In the one column I have true or false values for whether the user is active or not. I am trying to get it so when the value is false, highlight the value. Right now my code for my table settings looks like this:
//Settings for datatable
$('#userTable').DataTable({
"jQueryUI": true,
"serverSide": true,
"ajax": {
"type": "POST",
url: "/Management/StaffGet",
"contentType": 'application/json; charset=utf-8',
'data': function (data) { console.log(data); return data = JSON.stringify(data); }
},
"columns": [
{ "data": "employeeNumber" },
{ "data": "firstName" },
{ "data": "lastName" },
{ "data": "role" },
{
"data": "active",
},
{
"data": "employeeNumber",
"render": function (data, type, full, meta)
{
return 'Edit | Delete ';
}
}
],
"order": [[ 0, "asc"]],
"paging": true,
"deferRender": true,
"processing": true,
"stateSave": false,
"lengthMenu": [[5, 10, 25, 50, -1], [5, 10, 25, 50, "All"]],
"pageLength": 10,
"pagingType": "simple_numbers",
"searching": false,
"createdRow": function ( row, data, index ) {
if (data[4] == "false" ) {
$('td', row).eq(5).addClass('highlight');
}
}
});`
Then my code for css is:
`<style type="text/css">
td.highlight {
font-weight: bold;
color: red;
}
</style>`
I feel like there is a problem with the setting on the column, any help is appreciated.
Try
$('#userTable').DataTable({
...
"createdRow": function( row, data, dataIndex ) {
//console.log(data[4]);
if ( data[4] == "false" ) {
//console.log($(row).find("td").eq(4).html());
$(row).find("td").eq(4).addClass( 'highlight' );
}},
...
The commented log statements are in there to check you are getting and comparing the correct data.
Tested with datatables 1.10.1
