Question

我正在尝试在添加到购物车表格上使用ajax。但似乎html表单未发送任何ajax请求。当我单击添加到购物车按钮时。它显示一个黑页，因为我在控制器上使用了该ajax检查方法。

控制器

 public function addToCart(Request $request){

    $product = Product::find($request->product_id);
    Cart::add($product->id, $product->title, 1, $product->price);

    $response = array(
        'status' => 'success',
        'msg' => 'Setting created successfully',
    );



    if($request->ajax())
        return \Response::json($response);

}

JavaScript-AJAX

$('#add').on('submit', function (e) {
     e.preventDefault();
     var pid = $('#product_id').val();
     var cat = $('#category_id').val();
     $.ajax({
          type: "POST",
          url: host + '/addToCart',
          data: {product_id: pid, category_id: cat},
          success: function( msg ) {
               $("#xx").append("<div>"+msg+"</div>");
          }
     });
 });

HTML表格

<form id="add" action="{{ route('addToCart') }}" method="POST">
    {{csrf_field()}}
    <input type="hidden" id="category_id" name="category_id" value="{{ $px->category_id }}">
    <input type="hidden" id="product_id" name="product_id" value="{{ $px->id }}">
    <input type="submit" value="Add to Cart" class="bg-color-input">
</form>
<div id="xx"></div>

我在哪里弄错了？

如果您忘记发送csrf_token，可以按照以下方法解决：

 <form id="add" action="{{ route('addToCart') }}" method="POST">
{{csrf_field()}}
<input type="hidden" id="category_id" name="category_id" value="{{ $px->category_id }}">
<input type="hidden" id="product_id" name="product_id" value="{{ $px->id }}">
<input type="button" id="submitBtn" value="Add to Cart" class="bg-color-input">
</form>
<div id="xx"></div>


 $('document').on('click','#submitBtn',function(){
 e.preventDefault();
 var pid = $('#product_id').val();
 var cat = $('#category_id').val();
 $.ajax({
      type: "POST",
      url: host + '/addToCart',
      data: {product_id: pid, category_id: cat,'_token','{{csrf_token()}}'},
      success: function( msg ) {
           $("#xx").append("<div>"+msg+"</div>");
      }
 });
});

或者您可以序列化表格：

    $('document').on('click','#submitBtn',function(){
   e.preventDefault();
 $.ajax({
      type: "POST",
      url: host + '/addToCart',
      data:$('#add').serialize(),
      success: function( msg ) {
           $("#xx").append("<div>"+msg+"</div>");
      }
 });
 });

html表单未向控制程序发送ajax请求
