根据没有按钮的选择计算价格

人气:126 发布:2023-01-03 标签: html jquery javascript sum multiplication

问题描述

我想将价格和乘法与IF语句相加,以澄清以下是变量的一些价格 私人=成人100,儿童50或共享=成人40,儿童30 成人ATV=100儿童80或无ATV=0

如果唯一的成人在网上预订,我希望价格的反应是两种选择的总和乘以成人的数量示例 与亚视分享的成人书籍SO 40+100=140*成人人数

如果成人和儿童与亚视共享预订,那么它的反应应该是 40+100=140*成人人数 30+80=110*儿童数量 结果应为总和(110*儿童数量)+(140*成人数量)

推荐答案

我做了多次更改,以便能够以更轻松的方式处理此问题:

第0步-HTML在adultschildren输入中包含id(以获取这些值) 步骤1-Html每次修改(更改儿童/成人、ATV/无ATV、私有/共享)后呈现不完全 第2步-JS计算新合计并呈现

带示例的Plnkr:https://plnkr.co/edit/XOebeFyHNXFswNI4

第0步&;1:html:

                onclick="updateTotal()"
              />
              <label for="withatv">With ATV</label>
              <input
                type="radio"
                name="atv"
                id="withoutatv"
                onclick="updateTotal()"
              />
              <label for="withoutatv">Without ATV</label>
            </div>
          </div>

第二步:

      function calculateTotal() {
        // Define based Prices
        const privateAdultPrice = 100;
        const sharedAdultPrice = 40;
        const privateChildrenPrice = 50;
        const sharedChildrenPrice = 30;

        const withAtvAdultPrice = 100;
        const withAtvChildrenPrice = 80;

        const noAtvPrice = 0;

        // Get the amount of adults and guests
        const adults = +document.querySelector('#adults').value;
        const children = +document.querySelector('#children').value;

        // Get the type of trip
        const isPrivate = document.getElementById('private').checked;
        const isWithAtv = document.getElementById('withatv').checked;        

        // Calculate the specific charge per type of user and type of trip
        const adultTripPrice = isPrivate ? privateAdultPrice : sharedAdultPrice;
        const childrenTripPrice = isPrivate ? privateChildrenPrice : sharedChildrenPrice;
        // Calculate the specific charge per type of user and the vehicule
        const adultVehiclePrice = isWithAtv ? withAtvAdultPrice : noAtvPrice;
        const childrenVehiclePrice = isWithAtv ? withAtvChildrenPrice : noAtvPrice;      

        // Finally, do the maths
        const adultPrice = adults * (adultTripPrice + adultVehiclePrice)
        const childrenPrice = children * (childrenTripPrice + childrenVehiclePrice)

        // return the value
        return adultPrice + childrenPrice;                  
      }

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