Question

我被分配了创建骰子游戏的任务。游戏的目标是下注$金额，骰子将反复滚动，直到用户用完钱。我必须计算用户在钱用完之前掷骰子的次数并将其存储在数组中。我使用了do..while循环来执行骰子滚动功能，我很困惑如何计算do..while循环运行的次数并将其存储在数组中。在正确的方向轻推将不胜感激！

   <script>
        var rolls = new Array();
        var maxMoney = new Array();
        var rollCountMoney = new Array();
        function rollDice(){
        do {
        var userInput = parseInt(document.getElementById("bet").value); 
        var wallet = userInput; 
        var d1 = Math.floor(Math.random() * 6) + 1;
        var d2 = Math.floor(Math.random() * 6) + 1;
        var diceTotal = d1 + d2;
            if(diceTotal === 7) {
                document.getElementById("bet").value = wallet += 4;
                alert("your rolled a " +diceTotal +"! You win $4");
        } else {
                document.getElementById("bet").value = wallet -= 1;
                alert("your rolled a " +diceTotal +"! You lose $1");
            }
        } while (wallet > 0) { 
        }

根据您的代码和变量名称。你可以保持这样的结果......

var rolls = new Array();
var maxMoney = 0;//Max Money
var rollCountMoney = new Array();
var count = 0;

function rollDice() {
  do {
    count++;
    var userInput = parseInt(document.getElementById("bet").value);
    var wallet = userInput;
    var d1 = Math.floor(Math.random() * 6) + 1;
    var d2 = Math.floor(Math.random() * 6) + 1;
    var diceTotal = d1 + d2;
    rolls.push(diceTotal);//keep the roll
    rollCountMoney.push(wallet);//keep the wallet
    if(wallet > maxMoney){
      maxMoney = wallet;//keep the max money
    }
    if (diceTotal === 7) {
      document.getElementById("bet").value = wallet += 4;
      alert("Round:" + count + ",your rolled a " + diceTotal + "! You win $4");
    } else {
      document.getElementById("bet").value = wallet -= 1;
      alert("Round:" + count + ",your rolled a " + diceTotal + "! You lose $1");
    }
  } while (wallet > 0) {}
  var displayMsg = "You have rolled " + count + " times!";
  displayMsg += "<br>Rolls:" + rolls;
  displayMsg += "<br>maxMoney:" + maxMoney;
  document.getElementById("display").innerHTML = displayMsg;


}

<div class="container-fluid">
  <div class="page-head">
    <h1 align="center">Lucky Sevens</h1>
  </div>
</div>
<div class="container" align="center">
  <table style="border: 1px solid black">
    <tr>
      <th>
        <h3 align="center">Lucky Sevens</h3>
      </th>
    </tr>
    <tr>
      <td>
        <form>
          Starting Bet:
          <input id="bet" type="text" />
        </form>
      </td>
    </tr>
    <tr>
      <td align="center">
        <button onclick="rollDice()">Play</button>
      </td>
    </tr>
    <tr>
      <td align="center" id="display"></td>
    </tr>
  </table>
