我无法在全部金额字段中显示选中的单选按钮值。我有10个旅行套餐和旅行详细信息，当有人单击某个特定旅行对应的旅行数量时，将会显示旅行名称

Answer 1

为解决此问题，我创建了一个新的Javascript函数来更新全价单选按钮和标签。您可以使用类似的方法进行预付款。实际上，每次调用DescribeDBInstances()时，我只会调用更新预付款方式，以使它们保持同步。

updateFullPayment

我还更新了您的Javascript函数，以调用我的Java代码并传递当前选择的价格，以便总价始终处于更新状态。

 function updateFullPayment(radio) {
   var value = parseInt(radio.value)
   var full_payment = document.getElementById("full-price");
   var full_payment_radio = document.getElementById("full-price-radio");
   full_payment.innerHTML = value;
   full_payment_radio.value = value;
 };

HTML现在看起来像这样。单击价格单选按钮将调用我创建的更新功能。

 function increasePrice(checkbox) {
   var increase = parseInt(checkbox.value);
   var price_inputs = document.getElementsByClassName("price-input");
   var price_span = document.getElementsByClassName("price");
   for (var i = 0; i < price_inputs.length; i++) {
     var price = price_inputs.item(i);
     var newValue = parseInt(price.value);
     if (price_inputs.item(i).checked) {
       var selectedPrice = price_inputs.item(i);
     }
     if (checkbox.checked) {
       var newValue = newValue + increase;
     } else {
       var newValue = newValue - increase;
     }
     price_span.item(i).innerHTML = newValue;
     price.value = newValue;
 }

   updateFullPayment(selectedPrice);
 };
