I have a Django Python webapp , i have a function :
def showreport(newrequest) :
rep1 = get_report_data(newrequest,2)
data={['columns':rep1[0],'rows':rep1[1]}
return JsonResponse(data,safe=False)
i call this function from javascript in HTML page , the data return is an array with two elements, 1 represent columns and the other the data.
I want to present in the HTML page the data in a DataTable object , and since the columns and data is dynamic i want to create the DataTable dynamically
In the HTML
In JavaScript
$(document).ready(function () {
$("#showresults").on('click', function(evt) {
evt.preventDefault();
$('#show_loading').show();
$('#theTable').hide();
froms = document.getElementById('startdate').value;
tos = document.getElementById('todate').value;
$.ajax({
type: "POST",
url: 'showreport',
data: {
'start_date' : froms,
'end_date' :tos,
'csrfmiddlewaretoken': '{{ csrf_token }}'
},
success: function (data, textStatus, jqXHR) {
$('#show_loading').hide();
var rowSet=data['rows'];
var columnset =data['columns'];
$('#theTable').DataTable({
"processing": true,
searching: false,
paging: false,
"bInfo" : false,
columns: [columnset] ,
data: [rowSet]
} );
$('#theTable').show();
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
$('#show_loading').hide();
alert("Error, please try again!");
}
});
});
});
Now the problem i have is that the Columns are not presented and the data is presenting only 1 row and it is not separated to columns.
In inspect mode , i can see
{"rows": [["Test1", "Test2"],["Test3", "Test4"] etc..., "columns": ["col1","col2"]}
What am i doing wrong.
Thanks,

I think you have an array of an array :)
try
change this
columns: [columnset],
data: [rowSet]
to this
columns: columnset,
data: rowSet

In laravel 6 app I use "yajra/laravel-datatables-oracle": "^9.4" and I need selecting 1 row and running ajax request on server to delete this row
I try to refresh table with draw() method and it does not work.
In my blade file :
#push('scripts')
var oTable;
$(document).ready(function () {
oTable = $('#my_tasks_data').DataTable({
processing: true,
serverSide: false,
info: false,
order: [],
});
$('div.dataTables_length select').select2({
theme: "bootstrap"
});
...
function taskComplete(rowId) {
$.ajax({
url: 'tasks/' + rowId + '/complete',
type: "post",
dataType: 'json',
data: {'_token': '{{csrf_token()}}'},
success: function (data) {
console.log('taskComplete success data::')
console.log(data)
console.log('oTable::')
console.log(oTable)
oTable.draw(); // THat does not work
alert( 'AFTER::' )
},
error: function (xhr) {
console.error(xhr)
}
});
}
I check oTable var and see : https://prnt.sc/ujyp14 It looks like valid Table object
Why it does not work and how it can be fixed?
Thanks!
I found decision with setting serverSide property to true
oTable = $('#my_tasks_data').DataTable({
processing: true,
serverSide: true,
and after that method oTable.draw() works ok
I have a problem here, first I create data tables after I select the user using select2, so the data is dynamic according to the selected user, then next to it there is an update data button, here serves to update the data from the API if there is the latest data, for the process the data update is no problem, but there is a problem in the data tables process where after the update process, the data tables don't want to be redrawn
$("#name").on("change",function(){
var cek_id = this.value;
$("#user_id").val(cek_id);
console.log(cek_id);
$('#getData').DataTable().clear().destroy();
var i = 1;
var VendorClient = $("#getData").DataTable({
order: [ 0, "asc" ],
processing: true,
serverSide: false,
ajax: "{{route('get-user-data')}}"+"/"+cek_id,
columns: [{
data: null,
render: function ( data, type, full, meta ) {
return meta.row+1;
} },
{
data: "fullname",
name: "fullname",
orderable:false
},
{
data: "date",
name: "date",
orderable:false
}
]
});
});
and here is the process when the data update is clicked
$("#get_data").on("click",function(){
var cek_id = $("#user_id").val();
var url = "{{route('get-update-data')}}"+"/"+cek_id,
$.ajax({
type: "get",
url: url,
dataType: "json",
success:function(data){
if(data.status=='success'){
$('#getData').data.reload();
}else{
$('#getData').data.reload();
}
}
});
});
I have tried various methods, including creating a globe variable for VendorClient, then after response ajax i'm adding this code VendorClient.ajax.reload(null, false); and get errorr (index):406 Uncaught (in promise) TypeError: Cannot read property 'ajax' of undefined
but it's not working, any ideas?
Try to redraw the table:
$('#getData').DataTable().clear().draw();
or
$('#getData').DataTable().columns.adjust().draw();
or
$('#getData').DataTable().columns.adjust().draw(false);
When using the filter box of a datatable, the rowId remains on the first record, and I cannot figure out why.
Here is the datatable (simplified as much as possible):
$.ajax({
url: 'process/getData.php',
type: 'POST',
data: data,
dataType: 'html',
success: function(data, textStatus, jqXHR){
var jsonObject = JSON.parse(data);
var table = $('#example1').DataTable({
"data": jsonObject,
"columns": [
{
"data": "MONDAY",
"fnCreatedCell": function (nTd, sData, oData, iRow, iCol)
{
$(nTd).html("<span class='checkMon'>+oData.MONDAY+</span>");
},
// columns for each work day
}
],
"paging": false,
"scrollY": 730,
"scrollX": true,
"bDestroy": true,
"stateSave": true,
"autoWidth": true
});
},
error: function(jqHHR, textStatus, errorThrown) {
console.log('fail: '+ errorThrown);
return false;
}
});
Outside of the datatable, I have onclick event handler:
$('#example1').on('click', 'tr > td > .checkMon', function(e)
{
e.preventDefault();
var $dataTable = $('#example1').DataTable();
var tr = $(this).closest('tr');
var data = $dataTable.rows().data();
var rowData = data[tr.index()];
console.log(rowData.UID);
});
Prior to filtering, when I click any cell, the console reads the correct rowData.UID.
The problem is when I filter and click the cell again, the console reads the first row's rowData.UID.
Does anyone see why this is happening and how to fix it?
If what you want to achieve is simply log into the console UID property of the object that sourced the row that holds the <span> you've clicked, following approach should work:
$('#example1').on('click', '.checkMon', function(e)
{
e.preventDefault();
const dataTable = $('#example1').DataTable();
const rowData = dataTable.row($(this).closest('tr')).data();
console.log(rowData.UID);
});
Also, consider using ajax option. With that you won't need to waste performance destroying/re-creating your table and that will make your code cleaner and safer.
I have a table using Datatable plugin. I have filtered what I want to delete and after deletion, I manage to empty the value.
After that, if I want to filter using the same text again, for example, I have ba 1 and ba 2 and after deleting ba 1, it still shows the cell when I entered ba on the filter textarea field. It suppose to display the remaining ba which are not deleted yet.
For your information, I'm not using built in Datatable Ajax method.
what I'm trying to do is I want it to reload the table with the new data without refreshing the page after ajax on success. How to do that?
My datatable :
var table1 = $('#table1').DataTable(
{
pageLength : 500,
lengthChange: false,
deferRender: true,
scrollY: 800,
scrollCollapse: true,
scrollX: true,
bSort: false,
cache: true,
autoWidth: false,
columnDefs: [
{
targets: 0,
checkboxes:
{
selectRow: true
}
}
],
select: {
style: 'multi',
selector: 'td:not(:nth-child(4), :nth-child(5), :nth-child(6), :nth-child(9), :nth-child(10), :nth-child(13), :nth-child(14), :nth-child(15), :nth-child(16), :nth-child(17), :nth-child(18), :nth-child(19), :nth-child(20), :nth-child(21), :nth-child(22), :nth-child(23), :nth-child(24), :nth-child(25))'
}
});
Here's my filtering function code :
table1.columns().every(function ()
{
var table = this;
$('.filter', this.header()).on('keyup change', delay(function (settings, data, dataIndex)
{
if (table.search() !== this.value)
{
table.search(this.value).draw();
}
}, 500));
});
Here's my AJAX success code for deletion based on selected checkbox:
$('.btnN2').click(function(){
var answer = confirm('Delete N2 : Are you sure you want to delete selected items?');
if (answer)
{
console.log('yes');
var rows = $(table1.rows({selected: true}).$('input[type="checkbox"]').map(function()
{
return $(this).prop("checked") ? $(this).closest('tr').attr('data-getstockcode') : null;
}));
var getstockcodes = [];
$.each(rows, function(index, rowId)
{
console.log(rowId)
getstockcodes.push(rowId);
});
$.ajax({
url: 'del_n2',
type: 'GET',
data: {"getstockcodes": JSON.stringify(getstockcodes)},
dataType: 'JSON',
success:function(data){
console.log(data);
$(table1.rows({selected: true}).$('input[type="checkbox"]').map(function()
{
if($(this).prop("checked"))
{
$(this).parents("tr:eq(0)").find(".note2").val('');
console.log('reset');
}
}));
}
});
}
else
{
console.log('cancel');
}
});
Here's my insert data based on keyup event
$(".note2").keyup(delay(function()
{
var stockcode = $(this).data("stockcode");
var stockname = $(this).data("stockname");
var value = $(this).val().replace(/(\r\n|\n)/g, "\\n");
$.ajax({
url: 'saveNote2',
type: 'GET',
data: 'stockcode='+stockcode+'&stockname='+stockname+'&value='+value,
dataType: 'JSON',
success: function(data){
console.log(data);
},
error: function(data){
console.log(data);
}
});
}, 300));
Just add this in your success function
table1.ajax.reload()
If you are using ajax datatable or local you need to make it like this
table1.clear();
table1.rows.add(your response data array);
table1.draw()
I have a modal with a search box within it, which when the search button is hit, has an ajax call which goes to the controller, which then returns a table of results, which is then put into a div. Like so:
$.ajax({
url: url,
data: JSON.stringify(viewModel),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
cache: false,
type: "POST",
success: function (result) {
if (result.success === true) {
$("#searchResultsPlaceHolder").show();
$("#searchResultsPlaceHolder").html(result.view, function() {
var noOfRows = $('#searchResultsTable tr').length;
if (noOfRows > 1) {
loadSearchDatatable();
}
});
}
},
error: function (responseText, textStatus, errorThrown) {
alert('Error - ' + errorThrown);
}
});
All that is fine, and works perfectly up until I try to make it a datatable. If I take out the lines
$("#searchResultsPlaceHolder").html(result.view, function() {
var noOfRows = $('#searchResultsTable tr').length;
if (noOfRows > 1) {
loadSearchDatatable();
}
});
and just have
$("#searchResultsPlaceHolder").html(result.view)
it works fine, it gives me a table with my results. But as this is in a modal, and the returned results may get quite lengthy, I want to use a datatable to implement pagination and sorting. But whenever I apply the loadSearchDatatable function to the table after the div is populated with the returned html, I get the error:
table id=searchResultsTable - Ajax error
The datatable actually appears, with the sort buttons and paging buttons present, but none of them do anything, and the table is longer than the length I specified (5). Here is my datatable function:
function loadSearchDatatable() {
$('#searchResultsTable').dataTable({
ajax: "data.json",
"bLengthChange": false,
'iDisplayLength': 5,
"bSort": true,
"sPaginationType": "full_numbers",
"bFilter": false,
"sDom": 'ft<"bottom"ilp>',
"bDestroy": false,
"aaSorting": [[0, "asc"]]
});
};
Does anyone have any idea how to fix this error?
Use the code below instead:
$("#searchResultsPlaceHolder").html(result.view);
var noOfRows = $('#searchResultsTable tr').length;
if (noOfRows > 1) {
loadSearchDatatable();
}
Also remove ajax: "data.json", in your function loadSearchDatatable().
