Question

当我使用 jquery 提交表单时，它显示一个空白页面，没有任何反应，日志中没有错误，update in the DB dosen't happen

HTML code：

<form id="editcart" method="post" action="">  
  <input type="text" id="pid" name="pid" value="${product.pid}" hidden/>
  <input type="text" id="spid" name="spid" value="${product.sub_pid}" hidden/>
  <input type="text" id="cartid" name="cartid" value="${product.cart_id}" hidden/>
  <input type="text" id="quantity" name="quantity" value="${product.quantity}" disabled/>
  <input type="button" value="Edit" class="enable"/>
  <input type="submit" value="Save" class="save" hidden/>
</form>

jquery代码：

        $('#editcart').submit(function() {

           var quant = $('#quantity').val();  
           var pid = $('#pid').val();
           var spid = $('#spid').val();
           var cartid = $('#cartid').val();

            $.ajax({
          type: "post",
            url: "/devilmaycry/register?action=editcart",
         data: {pid:pid,quant:quant,spid:spid,cartid:cartid},

         success:   
                   function() 
                    {
                         alert("Item quantity has been changed in cart");
                },
                  error:
                     function(xhr) 
                    {
                         if (xhr.responseText=="Stock left is less than desired")
                            alert("Stock is less"); 

                         else if(xhr.responseText=="Internal server error")
                             alert("item cannot be added , internal server error");
                } 
              });
              return false; 
   });

我无法在表单提交后得到它的功能，但肯定不会做它应该做的事情...... URL也保持不变
