我在整理这个“穷人”刽子手时遇到了一些麻烦，这是我班上的一部分。我已经完成了它，但我有一件事阻止我完成。
我的问题是，我想我的
nextGuess = nextGuess.concat(String.valueOf( guess.charAt(i) ));
正在用空格替换我的“*”占位符。这个词必须用星号掩盖并间隔开，所以“披萨”将是“* * * * *”。
然而，当按下一个字母时，单词中的某些字符会从游戏区域中消失。有任何想法吗？

答案 0 :(得分：1)
这是将模型/数据与演示文稿/视图混合的典型示例
console.log(data.affectedColumns[0].name);
有更多字符，然后guess，但您尝试根据currentWord的索引将guess中的值连接到其中......这是不匹配的。
相反，我只是在currentWord和guess之间保持1-1关系，因此它们具有相同数量的字符，只是改变它的显示方式......
因此，当您致电currentWord时，您需要先格式化文字，例如gameField.setText(guess);
gameField.setText(pad(guess));可能看起来像......
pad只是在每个角色之间注入一个空格。
这也意味着当你这样做时
protected String pad(String value) {
StringJoiner sj = new StringJoiner(" ");
for (char c : value.toCharArray()) {
sj.add(Character.toString(c));
}
return sj.toString();
}
您实际上会获得有效的结果（因为if (guess.equals(currentWord)) {
不等于p i z z a：P）
