在 Laravel 中，我使用 ajax 通过 Blade 模板从 MySQL 数据库添加和获取数据，我在 onsubmit 事件上添加了表单求和。请帮助我。
我的代码是。 路线.php
Route::get('admin/bill',[BillingController::class, 'bill'])->name('billing');
Route::post('admin/billing/add',[BillingController::class, 'billadd'])->name('admin.bill.add');
控制器.php
public function billadd(Request $request){
$request->validate([
'customer_name'=>'required',
'mobile_number'=>'required',
'current_date'=>'required',
'current_time'=>'required',
'bill_number'=>'required',
'product_name'=>'required',
'batch_number'=>'required',
'variant'=>'required',
'price'=>'required',
'quantity'=>'required',
'tax_percent'=>'required',
]);
$posBill = new PosBilling();
$posBill->customer_name=$request->customer_name;
$posBill->customer_phone=$request->mobile_number;
$posBill->billing_date=$request->current_date;
$posBill->billing_time=$request->current_time;
$posBill->bill_number=$request->bill_number;
$posBill->product_name=$request->product_name;
$posBill->batch_number=$request->batch_number;
$posBill->variant = $request->variant;
$unitPrice = $posBill->price = $request->price; // One product price
$totalQuantity = $posBill->quantity = $request->quantity; // Total quantity of product
$totalAmount = $posBill->quantity_value = $unitPrice * $totalQuantity; // Total amount of product
// Discount Calculation
$discountPercent = $posBill->discount_percent = $request->discount_percent; // Discount percent
$discountPrice= $posBill->discount_amt = ($totalAmount) * ($discountPercent / 100); // Discount amount
$amountWithDiscount= $posBill->amount_with_discount = $totalAmount - $discountPrice; // with Discount amount of products
// Tax Calculation
$taxPercent= $posBill->tax_percent = $request->tax_percent; // Tax percent of product
$TaxPrice = $posBill->tax_amount = ($amountWithDiscount) * ($taxPercent / 100); // Amount of products tax
$CGST = $TaxPrice / 2; // CGST amount of products
$SGST = $TaxPrice / 2; // SGST amount of products
$amountWithTax = $posBill->net_amount = $TaxPrice + $amountWithDiscount; // with Tax amount of products
$i= 1;
if($i == 1){
$posBill->save();
$i++;
// echo $i;
}
if($i>1){
$billNumber = $request->bill_number;
$billingProduct = PosBilling::where('bill_number', $billNumber)->get();
}
return response()->json(['billingProduct'=>$billingProduct]);
}

blade.php（ajax 代码）
<script>
jQuery('#add').onsubmit(function(e){
e.preventDefault();
alert("Test");
break;
var formData = jQuery(this).serialize();
$.ajax({
url: "{{ route('admin.bill.add') }}",
type: "post",
data: formData,
success: function(response){
console.log(response);
}
});
});
</script>
我正在尝试在不加载页面的情况下提交数据并使用一个控制器功能获取数据。
在表单标签中请按以下方式添加操作
<form method="post" action="javascript:void(0)" id="addProduct">
还有一件事 请将行
jQuery(this).serialize()jQuery('#addProduct').serializetype="submit"
