Question

我正在制作这个刽子手游戏时遇到麻烦。我正在添加基本功能，这样如果你猜不出正确的字母，那么guessNumber变量会减1。我使用当前代码时遇到的问题是，当玩家猜到一个不正确的字母时 - 它会完全退出while循环。我是在构建我的while循环还是 guessNumber - 的定位？我一直在修补这段代码大约一个小时，仍然无法解决这个问题！

from django.conf import settings
from django.conf.urls import url
from django.conf.urls.static import static
from . import views

urlpatterns = [
        url(r'^(index\.?[html]{,4})?$', views.index, name='index'),
#       url(r'^index$', views.index, name='index'),
] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

每次循环找不到该字母时，您正在递减guessNumbers。 guessNumbers--需要在循环之外，因此每次输入只会减少猜测次数。

// array of words
var words = [
"trajectory", "symphony", "desire", "antfarm", "dancer", "happiness", "positioning",
"hobbit", "obituary", "cheetah", "sunrise", "antithesis", "wrong", "diamonds",
"partnership", "oblique", "sanctuary"];

// pick a random word

var word = words[Math.floor(Math.random() * words.length)];

// set up the answer array
var answerArray = [];

for (var i = 0; i < word.length; i++) {
    answerArray[i] = "_";
}

var remainingLetters = word.length;

//amount of guesses

var guessNumber = 5;

//the game loop

while (remainingLetters > 0 && guessNumber > 0) {
    //show the player their progress
    alert("Your word is " + answerArray.join(" ") + "and you have " +guessNumber+ " guesses left");

    //get a guess from player
    var guess = prompt("Guess a letter, or click cancel to stop playing.");
    if (guess === null) {
        //exit the loop
        alert("Ok you can quit");
        break;
    } else if (guess.length !== 1) {
        alert("Please enter a single letter.");
    } else {
        //update the game state with the guess
        for (let j = 0; j < word.length; j++) {         
            if (word[j] === guess) {
                answerArray[j] = guess;
                remainingLetters--;
            }
         }
         guessNumber--;
    }
} //end game loop

//alert to congratulate player
alert(answerArray.join(" "));
if (remainingLetters === 0) alert("Good job! The answer was " + word);
else alert("No more guesses! The answer was " + word);
