`<button type="button" class="btn btn-primary refund-initiate-btn"
                                    data-prn="{{ $item->PRN }}"
                                    data-rpptxnid="{{ $item->RPPTxnId }}"
                                    data-amount="{{ $item->AMOUNT }}"
                                    style="width: max-content;">Refund Initiate</button>`

字符串
我有这个按钮包含所有的值，我想在控制器上显示，所以对于这第一次我调用 AJAX 存储值比我在控制器传递AJAX

` <script>
            $(document).ready(function() {
                // Function to handle the "Refund Initiate" button click
                $(".refund-initiate-btn").on("click", function() {
                    var prn = $(this).data("prn");
                    var rpptxnid = $(this).data("rpptxnid");
                    var amount = $(this).data("amount");
        
                    // Create an object with the data to be sent
                    var requestData = {
                        prn: prn,
                        rpptxnid: rpptxnid,
                        amount: amount,
                    };
                    console.log(requestData);
                    // Make the API call using AJAX
                    $.ajax({
                        url: "{{ route('refundlog') }}",
                        type: "POST",
                        data: JSON.stringify(requestData), // Convert data to JSON format
                        contentType: "application/json", // Set content type to JSON
                        dataType: "json",
                        beforeSend: function(xhr) {
                            xhr.setRequestHeader('X-CSRF-TOKEN', "{{ csrf_token() }}"); // Set CSRF token header
                        },
                        success: function(response) {
                            // Handle the API response here
                            console.log(response);
                            // You can process the response here or display it on the page
                        },
                        error: function(xhr, status, error) {
                            console.error(error);
                            // Handle API error here if any
                        }
                    });
                });
            });
        </script>`

控制器

` $prn = $request->input('prn');
        $rpptxnid = $request->input('rpptxnid');
        $amount = $request->input('amount'); `

所有的价值，我可以看到完美 AJAX 调用，但当涉及到控制器，它不取请你能告诉我什么是错的吗
