Question

我是javascript的新手，并且在我的Hangman游戏中显示猜测的字母时出现问题。当用户点击＆＃34;猜测＆＃34;按钮，checkinput（）方法应该启动，这应该运行：

//loop through word and if guess equals the character of the inputted work, replace - with letter. 
    for (i = 0; i < input.length; i++) {
        //if user's guess is matched against one of the letters of the word, this will execute. 
        if (guess == input.substring(i, i + 1)) {
            placeholder = placeholder.substring(0, i) + guess + placeholder.substring(i + 1, placeholder.length);
            spguess.innerHTML = placeholder;
            //if guessed letter is wrong, push into wrongg array
        } else if (guess != input.substring(i, i + 1)){ 
            wrongg.push(guess);
            console.log(wrongg);
            }
        }
    }

其他部分是我遇到问题的地方。我希望能够安装猜测的字母（错误的字母与输入的单词不匹配）。你能指出我正确的方向吗？ https://jsfiddle.net/gdbn47or/是jsfiddle

我觉得你有问题，因为你在你的周期中有你的wrongg.push，所以即使猜测是正确的第四个字母，它仍然会进入错误的数组3甚至更多次，你应该做什么对于每个循环，你应该有一个布尔值（找到），然后将你的if改为：

    if (guess == input.substring(i, i + 1)) {
        placeholder = placeholder.substring(0, i) + guess + placeholder.substring(i + 1, placeholder.length);
        spguess.innerHTML = placeholder;
        found = true;
    }

如果找到的布尔值为假，则只在for循环后执行else if else
