table.data after table.ajax.reload(); shows data from before the reload

mrd05d

I am using DataTables and the TableTools extension. Im using an ajax button to send selected rows to be deleted from the db. On success i am using table.ajax.reload();. Then after I am trying to see if the result set is empty or not if it is i want to reload the page.

I tried to use table.data() but it is seeing what was in the table prior to the reload not after?

So i decided to attach an xhr event handler instead of waiting for the table to reload in order to then try and evaluate for empty.

This works well:

 table = $('#example').on('xhr.dt', function ( e, settings, json ) {
                            if ("data" in json) {
                                if (json['data']===""){
                                    location.reload();

                                }
                            }
                            


                        } ).DataTable( {
                        "processing": true,
                        "serverSide": false,
                        "lengthMenu": [[10,15, 20, 30, -1], [10, 15,20, 30, "All"]],
                        "pageLength":15,
...

That is the correct thing to do :-). The other option is to use initCallback at initialisation time, or the callback for reload.ajax() if you are using that method.
