根据没有按钮的选择计算价格
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)

</html>解决方案
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
adults、children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;
}
