作为我的任务的一部分，我正在制作一个简单的刽子手游戏，用户点击字母字母，然后应该交换正确的字母，否则显示为_。
我知道问题是myWord[i].innerHTML = guess;以及为什么，但我不知道在这里还有什么用。
如果您不想查看整个代码段，那么应该处理它的功能如下：
function wordOnClick() {
var guess = this.innerHTML; //Usikker
this.className = "active";
this.onclick = null;
for (var i=0; i<saveWord.length; i++) {
if (saveWord[i] === guess) {
myWord[i].innerHTML = guess;
var bool = true;
winCounter++;
}
}
if (bool != true) {
counter --;
animateMan();
}
if (counter === 0) {
document.getElementById("buttons").className = "active";
}
if (winCounter === saveWord.length) {
lifePool.innerHTML = "Congratz, you've won!";
hangmanbtn.style.display = "inherit";
}
}
这里的全部代码：
hangmanbtn.onclick = function() {
hangman();
};
/*
* Hangman!
* Runs when you click PLAY!
*/
function hangman() {
hangmanStyle();
createbuttons();
incompleteWord();
/*
* RESET CANVAS ON NEW GAME
*/
var canvas = document.getElementById("hangman");
var ctx = canvas.getContext("2d");
ctx.beginPath();
ctx.clearRect(0, 0, canvas.width, canvas.height);
/*

hangmanbtn.style.display = "none";
hiddenCanvas.style.display = "none";
lifePool.innerHTML = "You have 6 lives";
document.getElementById("buttons").className = "";
/*

var saveWord;

var guess;
var usedGuesses = [];
var getWord;
var myWord = document.getElementById("myWord").innerHTML;

答案 1 :(得分：1)
在line 40文件的.js上，您要将innerHTML ul个myWord个myWord分配给变量ul。您应该做的是分配 var myWord = document.getElementById("myWord").childNodes; //no innerHTML的子节点，如下所示：
return usedGuesses另外，我建议在line 110删除无法访问的返回语句stats -r "$(cat test_file)"。希望有所帮助。
答案 2 :(得分：0)
我想我发现了这个问题。逻辑问题。 myWord是一个字符串变量而不是数组。你在这里定义var myWord = document.getElementById("myWord").innerHTML;。
现在guess也是一个字符串，saveWord也是如此。
当您将saveWord中的每个字符与guess if (saveWord[i] === guess) myWord中的每个字符进行比较并存储在if (saveWord[i] === guess[i])中时，您必须这样做，
myWord[i]= guess[i];和for (var i=0; i<saveWord.length; i++) {
if (saveWord[i] === guess[i]) {
myWord[i] = guess[i];
var bool = true;
winCounter++;
}
所以我的假设解决方案是：
