我在Laravel 5.8中使用Yajrabox数据表。在我的一种观点中，我收到此错误： DataTables警告：表格ID = DataTables_Table_0-Ajax错误。
问题是出现错误，对控制器的3/4个调用中有1个。因此，我认为这里存在某种比赛情况，但无法弄清楚哪里。
在控制台中返回的错误是“找不到404”，并且网络响应是：

Ajax代码是：
$(function () {
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
var table = $('.data-table').DataTable({
processing: true,
serverSide: true,
ajax: "{{ route('purchases.index') }}",
columns: [
{data: 'action', name: 'action', orderable: false, searchable: false, width: "55px"},
{data: 'date', name: 'date'},
{data: 'refno', name: 'refno'},
{data: 'title', name: 'title'},
{data: 'sup_invno', name: 'sup_invno'},

{data: 'nettotal', name: 'nettotal'},
{data: 'remarks', name: 'remarks'},
{data: 'status', name: 'status'},
// {data: 'detail', name: 'detail'},

});
，控制器代码为：
public function index(Request $request)
{
$branch_id=session()->get('lbranch','0');
if ($branch_id==0){
return response()->json(['errors'=>'Branch not selected.']);
}
if ($request->ajax()) {
$data = DB::table('purchases')
->where('purchases.branchid',$branch_id)

->leftjoin('accounts','purchases.account_code','=','accounts.code')
->select('purchases.*',
DB::raw('(CASE
WHEN purchases.posted = "1" THEN "Posted"
ELSE "Unposted"
END) AS status'),
'accounts.title')
->latest()->get();
return Datatables::of($data)
->addIndexColumn()
->addColumn('action', function($row){
$btn = '<a href="javascript:void(0)" data-toggle="tooltip" data-id="'.$row->id.'" data-original-title="Edit" class="edit btn btn-primary btn-sm editPurchase"><i class="fa fa-edit"></i></a>';

return $btn;

->make(true);
}
return view('purchases',compact('purchases'));
}
