如何在单选按钮中显示金额值

Question

您好，我正在开发我的项目。如何调用onclick按钮的ajax函数。

If(isset($_POST) && ($_POST[‘GET_PAYMENT’] == ‘1’))
{

 $totalAmount = $_POST[‘GET_PAYMENT’]; //Total amount
 $checkbox_id = $_POST[‘VALUE’]; // The radio button value 

        /* Here get the amount values (3,5.5 or 10) from 

         Database based on the $checkbox_id and store it in

 $amount variable*/


 $total_amount = $amount + $totalAmount;


 Echo $total_amount;

}


$.ajax({
   type: "POST",
   url: "ajax.php",
   data: "GET_PAYMENT=1&VALUE=”+ checkboxVal,
   success: function(total_amount)
   {
 //Assigning the final value to the hidden value here
 $(‘#totalamount’).val(total_amount);  

 //Here changing the display of total amount
 $(‘#repair_total_amount’).html(“Total <span class="repair-finalamount-txt">&pound;&nbsp;”+ total_amount+”</span>”);

   }
 });

}

我对此感到困惑：data: "GET_PAYMENT=1&VALUE=”+ checkboxVal，我必须执行哪个操作。这是因为当我单击该单选按钮时，它将与 addcart 一起添加。

任何一个都可以

我认为你应该使用：

$.ajax({
   type: "POST",
   url: "ajax.php",
   data: {GET_PAYMENT: 1, VALUE: checkboxVal},
   success: function(total_amount)
   {
 //Assigning the final value to the hidden value here
 $(‘#totalamount’).val(total_amount);  

 //Here changing the display of total amount
 $(‘#repair_total_amount’).html(“Total <span class="repair-finalamount-txt">&pound;&nbsp;”+ total_amount+”</span>”);

   }
 });

编辑：

好的，等等。我认为这里真正出问题的是您将GET_PAYMENT 的值（始终为1）添加到$total_amount。试试：$total_amount = $amount + $checkbox_id;，或者更好：

$selected_amount = (int) $_POST['VALUE'];
$total_amount = $amount + $selected_amount;
