我被分配了一个创建骰子游戏的任务。游戏的目的是下注一定数量的美元，骰子会不断滚动，直到用户用完钱为止。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 循环来执行掷骰子功能，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。如果能朝正确的方向插入，我们将不胜感激，谢谢!
<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) {
}
}

最佳答案
根据您的代码和变量名称。您可以像这样保留结果...
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;
