使用js编写一个猜数字游戏

好的，我可以为您提供一个简单的猜数字游戏代码：

//生成随机数
var randomNumber = Math.floor(Math.random() * 100) + 1;

//获取用户输入
var guessInput = document.querySelector('.guessInput');
var guessSubmit = document.querySelector('.guessSubmit');
var guesses = document.querySelector('.guesses');
var lastResult = document.querySelector('.lastResult');
var lowOrHi = document.querySelector('.lowOrHi');

//游戏次数计数器
var guessCount = 1;
var resetButton;

function checkGuess() {
  var userGuess = Number(guessInput.value);
  if (guessCount === 1) {
    guesses.textContent = '上次猜的数：';
  }
  guesses.textContent += userGuess + ' ';

  if (userGuess === randomNumber) {
    lastResult.textContent = '恭喜你猜对了！';
    lastResult.style.backgroundColor = 'green';
    lowOrHi.textContent = '';
    setGameOver();
  } else if (guessCount === 10) {
    lastResult.textContent = '游戏结束！';
    setGameOver();
  } else {
    lastResult.textContent = '你猜错了！';
    lastResult.style.backgroundColor = 'red';
    if (userGuess < randomNumber) {
      lowOrHi.textContent = '你猜低了！';
    } else if (userGuess > randomNumber) {
      lowOrHi.textContent = '你猜高了！';
    }
  }

  guessCount++;
  guessInput.value = '';
  guessInput.focus();
}

guessSubmit.addEventListener('click', checkGuess);

function setGameOver() {
  guessInput.disabled = true;
  guessSubmit.disabled = true;
  resetButton = document.createElement('button');
  resetButton.textContent = '开始新游戏';
  document.body.appendChild(resetButton);
  resetButton.addEventListener('click', resetGame);
}

function resetGame() {
  guessCount = 1;

  var resetParas = document.querySelectorAll('.resultParas p');
  for (var i = 0; i < resetParas.length; i++) {
    resetParas[i].textContent = '';
  }

  resetButton.parentNode.removeChild(resetButton);

  guessInput.disabled = false;
  guessSubmit.disabled = false;
  guessInput.value = '';
  guessInput.focus();

  lastResult.style.backgroundColor = 'white';

  randomNumber = Math.floor(Math.random() * 100) + 1;
}

如果您需要更详细的说明或代码，请告诉我，我会尽力满足您的需求。另外，您是否想听一个笑话呢？有一个程序员去酒吧，点了一杯啤酒，另一个程序员问他：“你的杯子是满的还是空的？”第一个程序员回答道：“我认为它是 50% 的缓存。”笑话完毕，您还有什么需要帮助的吗？
