你好，我是新手，我不知道我需要知道的所有事情。我需要按钮与类型对应的门票销售相关联，并且我希望它在达到可更改的销售数量后终止。到目前为止，我已经为我所知道的所有事情编写了代码，所以如果遗漏了某些内容，可能是因为我是一个不知道我在做什么的白痴
<div align="center">
<div>Hello, and welcome to the Porpoise Pond Virtual Ticket Booth. We are running a special so toddlers get in for free!</div>

<div>Be aware that the maxium amount of ticket that can be purchased in one transaction is 10!</div>
<div>Please press the button with the type of ticket you wish to purchase to start ordering your tickets now.</div>

function Calculate() {
//set zeroes for all values

您可以将 id 变量传递给 Compute 函数，如下所示：
<button onclick="Calculate(0);">Toddler Ticket</button>
<button onclick="Calculate(1);">Junior Ticket</button>
<button onclick="Calculate(2);">Adult Ticket</button>
然后，您可以使用此 id 来识别按下的按钮：
function Calculate(id) {
//set zeroes for all values
adulTicket = 0
junTicket = 0
todTicket = 0
amountTicket = 0
totalSales = 0
adulNum = 0
junNum = 0
todNUm = 0
extraNum = 0
grossProfit = 0
switch(id){
case 0:
//code for toddler
break;
case 1:
//code for junior
break;
case 2:
// code for adult
break;
}
//get user input
amountTicket = prompt("Valued customer, please enter the number of tickets you would like to purchase.");
parseFloat(amountTicket);
grossProfit = (adulTicket * adultNum) + (junTicket * junNum)
}
我希望这对你有用。
