Question

我想改变这个我制作的刽子手游戏，这样每次按下新游戏时，它都会按照它们所处的确切顺序进行随机操作。

    // constants
    var POSSIBLE_WORDS = ["first", "second", "third"];
    var MAX_GUESSES = 7; // number of total guesses per game

    // global variables
    var word = "?"; // random word user is trying to guess
    var guesses = ""; // letters the player has guessed
    var guessCount = MAX_GUESSES; // number of guesses player has left
    var borderColor = 60;

    // Chooses a new random word and displays its clue on the page.
    function newGame() {
// choose a random word
    var randomIndex = parseInt(Math.random() * POSSIBLE_WORDS.length);
    word = POSSIBLE_WORDS[randomIndex];
    guessCount = MAX_GUESSES;
    guesses = "";
    borderColor = 60;
    document.getElementById("hangmanpic").style.border = "thin none hsla(0,0%,100%,1)";
    document.getElementsByTagName("body")[0].style.backgroundColor = "hsla(0,0%,100%,1)";
    updatePage(); // show initial word clue - all underscores
        }

Answer 1

首先，设置一个计数器变量：

var LAST_INDEX=0;

接下来，在newGame()函数的顶部，选择LAST_INDEX，然后将LAST_INDEX增加1，而不是选择随机索引。

word=POSSIBLE_WORDS[LAST_INDEX];
++LAST_INDEX;

应该这样做。

Answer 2

定义一个变量来保存当前单词的索引：

var currIndex = 0;

然后在newGame中递增计数器而不是生成随机数：

word = POSSIBLE_WORDS[currIndex];

currIndex = (currIndex + 1) % POSSIBLE_WORDS.length;   // for the next round

这将按顺序旋转单词。

如果你不想旋转，那么删除mod部分（%）并只增加currIndex并通过与POSSIBLE_WORDS.length进行比较来检查列表的结尾
