Question

我正在编写一个《 Hangman》游戏，即使多次检查都没有发现任何错误，但仍然出现此错误。
我确实在Stack Overflow上阅读了有关此内容的内容，但找不到适合我的特殊情况的解决方案。它不是一个函数，因此应该是一个中断而不是返回。

我的代码：

    <h2>Hangman</h2>    

    <script> 
        // pick our random words for the game & save in an array in a 
        varibale
        var word = [
         "school",
         "teacher", 
         "class", 
         "principal"];

        // use this to pick a random word from the array
        var word = words[Math.floor(Math.random() * words.length)];

        // create an empty array and fill it with underscores to match the number of letters in a word
        var answerArray = [];
            for (var i = 0; i < word.length; i ++) {
            answerArray[i] = "_";
            }
        // variable set to the length of the secret word; use this to keep track of how many letters are left to guess
            var remainingLetters = word.length;

        // we will continue to loop as long as the number of letters is greater than zero; once it is zero they have correctly guessed the word; .join changes an array into a string
            while (remainingLetters > 0) {
            alert(answerArray.join("  "));
            }
        // prompt takes a guess from the player and saves it to the varible guess; now we must handle 4 separate scenarios: the player does not provide a letter, the letter is greater than 1, the player does it correctly
            var guess = prompt("Guess a letter, or click cancel to stop playing.");
        if (guess === null) {
            // exit the game loop
            break;  
        }else if (guess.length !== 1) {
            alert("Please enter a single letter.");

        }else {
            for (var j =0; j < word.length; j++){
                if (word[j] === guess) {
                    answerArray[j] = guess;
                    remainingLetters --;
                }
            }
        }

        alert(answerArray.join(" "));
        alert("Good. The answer was "  + word);

你必须把你的代码放在While循环中……像这样然后中断；会工作，因为它在循环中::::)))

while (remainingLetters > 0) {
    alert(answerArray.join("  "));

    var guess = prompt("Guess a letter, or click cancel to stop playing.");
    if (guess === null) {
        // exit the game loop
        break;
    } else if (guess.length !== 1) {
        alert("Please enter a single letter.");
    } else {
        for (var j =0; j < word.length; j++){
            if (word[j] === guess) {
                answerArray[j] = guess;
                remainingLetters --;
            }
        }
    }
}

alert(answerArray.join(" "));
alert("Good. The answer was "  + word);
