سلام
کد زیر را زدم ولی وقتی request را dd میکنم مقدار ارسال شده فرم را نشون نمیده و یکسری اطلاعات دیگه مربوط به هدرها و .... نشون میده

    <script>
        function showPrice(valuess) {
            if (valuess == "") {
                document.getElementById("order_price").innerHTML = "";
                return;
            }
            if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
                xmlhttp = new XMLHttpRequest();
            } else {// code for IE6, IE5
                xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
            }
            xmlhttp.onreadystatechange = function () {
                if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                    document.getElementById("order_price").innerHTML = xmlhttp.responseText;
                }
            };
            xmlhttp.open("get", "check_price/" + valuess, true);
            xmlhttp.send();
        }
    </script>

<div class="col-lg-4">
                            <div class="form-label-group position-relative has-icon-left ">
                                <select class="form-control select2" name="product" onchange="showPrice(this.value)">
                                    @foreach($products as $product)
                                        <option value="{{$product->id}}">{{$product->title}}</option>
                                    @endforeach
                                </select>
                                @error('accounting_id') <span class="text-danger">{{$message}}</span> @enderror
                            </div>
                            <div class="text-dark rounded p-1" id="order_price"></div>
