【问题描述】：

我被困在二十一点任务上。我不知道如何让用户说出他们想要的多次hitMe Y/N。我的经销商面朝下。

let card = 0;
let total = 0;
let hitMe = true;
let dealer = 0;

//1st card
hitMe = prompt("Current total: " + total, "Take a card? Y/N");
// (hitMe == "Y")hitMe = true;
//se hitMe = false;
if(hitMe)
card = dealer = Math.ceil(11*Math.random()) + Math.ceil(11*Math.random());
total += card;



//final total
dealer = Math.ceil(11*Math.random()) + Math.ceil(11*Math.random()); //dealer always takes 2 cards
alert("Your hand is worth " + total + ". Dealer got " + dealer + ".");

【问题讨论】：

请澄清您的具体问题或提供更多详细信息以准确突出您的需求。正如目前所写的那样，很难准确地说出你在问什么。

【参考方案1】：

使用 if 语句和 while 循环，如下所示：

  let card = 0;
  let total = 0;
  let hitMe = true;
  let dealer = 0;

  hitMe = prompt("Current total: " + total, "Take a card? Y/N");

  if(hitMe == "Y")
    while(hitMe == "Y")
      card = dealer = Math.ceil(11*Math.random()) + Math.ceil(11*Math.random());
      total += card;
      hitMe = prompt("Current total: " + total, "Take a card? Y/N");
    
   else 
    dealer = Math.ceil(11*Math.random()) + Math.ceil(11*Math.random());
    alert("Your hand is worth " + total + ". Dealer got " + dealer + ".");
  

如果用户没有输入 Y，将显示最终的总数。
