Hola, estoy usando datatable y necesito eliminar varios datos usando la casilla de verificación, estoy usando el método de publicación javascript,

Controlador

 public function deleteselected(Request $request){ $ids = $request->ids; Product::whereIn('id', $ids)->delete(); return response()->json(['code'=>1, 'msg'=>'Products have been deleted from database']); }

JavaScript

 $.post(url,{countries_ids:checkedCountries, _token: "{{ csrf_token() }}", _method: "POST"},function(data){ if(data.code == 1){ $('#geniustable').DataTable().ajax.reload(null, true); toastr.success(data.msg); } },'json');
