javascript - 为什么我的程序会跳过游戏部分？

转载作者：行者123 更新时间：2023-12-03 10:50:20

我写了一个非常基本的刽子手游戏，但它跳过了实际的刽子手部分。它将显示该词有多长的警报，然后按“确定”，然后显示完成消息，没有游戏部分，我不知道为什么请告诉我出了什么问题刽子手

<body>
    <h1>Hangman!</h1>


    <script>
    var words = [
        "javascript",
        "monkey",
        "amazing",
        "pancake",
      ];
      var word = words[Math.floor(Math.random() * words.length)];
      var answerArray = [];
      for (var i = 0; i < word.length; i++) {
        answerArray[i] = "_"
      }

      var remainingLetters = word.length

      while (remainingLetters < 0) {

      alert(answerArray.join(" "));

      var guess = prompt("Guess a letter, or click Cancel to stop playing>");
      if (guess === null) {
            break;
      } else if (guess.length !== 1) {
      alert("Please enter a single letter.");    
      } else {
            //update the game state with a guess
      for (var j = 0; j < word.length; j++) {
        if (word[j] === guess) { 
          answerArray[j] = guess;
          remainingLetters--;
         } 
        }
       }
      }
      alert(answerArray.join(" "));
      alert("Good Job! The answer was " + word);
    </script>

最佳答案

while (remainingLetters < 0) {应该是while (remainingLetters > 0) { .

另外，如Pluto提到它(很好!)，您可以通过一遍又一遍地输入相同的字母来作弊。为了解决这个问题，您可以将猜测的字母存储在字符串中，并检查之前是否猜测过(并且不增加分数)。

另一个调整，如果用户点击取消(想要退出)，我添加了一个 if语句放在最后，这样就不再显示警报。

var words = ["javascript", "monkey", "amazing", "pancake"];
var word = words[Math.floor(Math.random() * words.length)];
var answerArray = [];
// Storing the letters already guessed
var guessedLetters = "";
for (var i = 0; i < word.length; i++) {
    answerArray[i] = "_"
}

var remainingLetters = word.length;

while (remainingLetters > 0) {

    alert(answerArray.join(" "));

    var guess = prompt("Guess a letter, or click Cancel to stop playing>");
    if (guess === null) {
        break;
    } else if (guess.length !== 1) {
        alert("Please enter a single letter.");
    } else {
        // if the letter was already guessed
        if (guessedLetters.indexOf(guess) > -1) {
            // skip
            continue;
        }
        //update the game state with a guess
        for (var j = 0; j < word.length; j++) {
            if (word[j] === guess) {
                answerArray[j] = guess;
                // add the letter to the guessed letters
                guessedLetters += guess;
                remainingLetters--;
            }
        }
    }
}
// if there are no remaining letters (if the user cancelled,
// no need to show these).
if( !remainingLetters) {
    alert(answerArray.join(" "));
    alert("Good Job! The answer was " + word);
}
