Error in Refreshing Datatable Using AJAX in Codeigniter

Error in Refreshing Datatable Using AJAX in Codeigniter



First sorry for my bad english.
I am trying to create button in my datatable. The button for delete data in that row. Delete function works. The problem is after the delete, my Datatable did not refresh the content (Only when I refresh the page, the content refreshed).



I already try some suggestion in other's stackoverflow.
My datatble id = "data'
var data as global variable.



This is my JavaScript Code (inside document.ready) :


var temp = $('#data').DataTable
(
"columns":
[
null, null, null, null,
null, null, null,
"width": "17%"
]
);

table = JSON.parse('"' + temp + '"');



This is my code for button function


function delete(kode)

var x = confirm("Do you want to delete this data?");

if (x == true)

jQuery.ajax(
type : "POST",
url : "***"
dataType : 'json',
success : function()

table.ajax.reload();
alert("delete success");
,
error : function()

table.ajax.reload();
alert("delete fail");

);



Error in console :



Uncaught Type-error: Cannot read property 'ajax' of undefined
at Object.error (hotel:191)
at u (VM226 jquery.js:2)
at Object.fireWith [as rejectWith] (VM226 jquery.js:2)
at k (VM226 jquery.js:2)
at XMLHttpRequest. (VM226 jquery.js:2)





"Cannot read property 'ajax' of undefined" - Where do you define a variable called table? Your DataTables instance is called temp. You also may not need to reload the whole set of data, just delete that one record from the data. And you probably don't need to reload or modify the table at all in the error callback, since the delete operation failed.

table


temp


error





Table is global variable. my bad, in my post, it should not data = JSON.parse('"' + temp + '"'); but it should be Table = JSON.parse('"' + temp + '"');

@David if I may know, why you said the delete opeartion failed? When I checked in my table in database (MySQL) , that row (data) deleted.

You need to write below in ajax success. It will retrieve or refresh all the data of it.


var $lmTable = $("#data").dataTable(bRetrieve: true);
$lmTable.fnDraw();





TypeError: table.fnDraw is not a function at Object.error (hotel:243) at u (VM140 jquery.js:2) at Object.fireWith [as rejectWith] (VM140 jquery.js:2) at k (VM140 jquery.js:2) at XMLHttpRequest.<anonymous> (VM140 jquery.js:2)

But even these fine fellas abikejourney.com have flown from Singapore to Australia. With the increasing difficulty in freighter tourism, this will be at least very challenging. – chx Dec 12 '16 at 10:01 add a comment  |  10 Is it possible to ride from Malaysia to Papua New Guinea by motorcycle.
