price depend on selection of radio input(价格取决于无线电输入的选择)

本文介绍了价格取决于无线电输入的选择的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我尝试了，但在此之后无法获得，因此请帮助我完成此操作。

我想设置成人价格，如果选择私人，则有亚视是100，没有亚视是10

但如果选择共享，则使用ATV时为50，不使用ATV时为5 对于儿童，如果选择了Private，则有ATV的为50，没有ATV的为5 但如果选择共享，则带ATV的为25，不带3的数据-lang="js"数据-隐藏="假"数据-控制台="假"数据-巴贝尔="假">

嗨我试过了，但在此之后无法获得，因此请帮助我处理此问题。

我想设置成人价格，如果选择私人，则有亚视的是100，没有亚视的是10

但如果选择共享，则使用ATV时为50，不使用ATV时为5

对于儿童，如果选择了Private，则有ATV的为50，没有ATV的为5 但如果选择共享，则带ATV的为25，不带3的

推荐答案

现在，您的价格取决于条件。

因此，计算方法略有不同。翻译您的话，在JS代码中应该是这样的：

const adultTripPrice = isPrivate && isWithAtv ? 100 : isPrivate ? 10 : isWithAtv ? 50 : 5;
const childrenTripPrice = isPrivate && isWithAtv ? 50 : isPrivate ? 5 : isWithAtv ? 25 : 3;

const adultPrice = adults * (adultTripPrice)
const childrenPrice = children * (childrenTripPrice)

它针对成人进行评估

isPrivate和isWithATV然后100
isPrivate(但不是isWithATV)然后10
isWithATV(但不是isPrivate)则为50
不是isPrivate也不是isWithATV然后是5。

，然后将该数字乘以成人数。(同样的逻辑也适用于孩子)

更新后的代码如下所示：

function calculateTotal() {
        const privateAdultPrice = 0;
        const sharedAdultPrice = 0;
        const privateChildrenPrice = 0;
        const sharedChildrenPrice = 0;

        const withAtvAdultPrice = 100;
        const withAtvChildrenPrice = 80;

        const noAtvPrice = 10;

        const adults = +document.querySelector('#adults').value;
        const children = +document.querySelector('#children').value;

        const isPrivate = document.getElementById('private').checked;
        const isWithAtv = document.getElementById('withatv').checked;        

        const adultTripPrice = isPrivate && isWithAtv ? 100 : isPrivate ? 10 : isWithAtv ? 50 : 5;
        const childrenTripPrice = isPrivate && isWithAtv ? 50 : isPrivate ? 5 : isWithAtv ? 25 : 3;
        const adultPrice = adults * (adultTripPrice)
        const childrenPrice = children * (childrenTripPrice)

        return adultPrice + childrenPrice;                  

      }
      function updateTotal() {
        const total = calculateTotal();
        console.log(total);
        document.querySelector('#totalPrice').innerHTML = total;
      }

      function increaseCount(e, el) {
        var input = el.previousElementSibling;
        var value = parseInt(input.value, 10);
        value = isNaN(value) ? 0 : value;
        value++;
        input.value = value;
        updateTotal();
      }

      function decreaseCount(e, el) {
        var input = el.nextElementSibling;
        var value = parseInt(input.value, 10);
        if (value > 1) {
          value = isNaN(value) ? 0 : value;
          value--;
          input.value = value;
        }
        updateTotal();
      }

      function decreaseCount2(e, el) {
        var input = el.nextElementSibling;
        var value = parseInt(input.value, 10);
        if (value > 0) {
          value = isNaN(value) ? 0 : value;
          value--;
          input.value = value;
        }
        updateTotal();
      }

      var MainImg = document.getElementById('MainImg');
      var smallimg = document.getElementsByClassName('small-img');

      smallimg[0].onclick = function () {
        MainImg.src = smallimg[0].src;
      };
      smallimg[1].onclick = function () {
        MainImg.src = smallimg[1].src;
      };
      smallimg[2].onclick = function () {
        MainImg.src = smallimg[2].src;

      smallimg[3].onclick = function () {
