Jquery Datatables validate server response

Question

I have a datatable pulling data from the server.

If all is ok it returns a perfectly valid json response which datatbles renders happily, if something is wrong server side it returns json error object as follows.

{"success":false,"message":"some error message"}

My table is defined as follows:

    Table = $('#usersTable').DataTable({
    "pagingType": "full_numbers",
    "serverSide": true,
    "processing": true,
     "ajax": {
          url:"/user/getUsers/"
             }
      });

How would I intercede to stop datatables doing anything so I could process the error message if response.success is defined and false?

I am using the latest version of jquery datatables

write your own ajax handler instead of just passing in the url. See docs for how utilize your own ajax within the options object for the plugin — charlietfl

Table.on( 'xhr.dt', function (e, settings, json) {
 if (!typeof json.success !== "undefined"){
 if ( json.success==false){
do something here
}
}
});
