我正在尝试在我的不和谐机器人中实现 js 代码。因此，我在网上获取了一些代码来尝试它是否正常工作，现在，我正在尝试像这样使用 queryselector：

if (msg.content === "!GuessNumber"){
    let randomNumber = Math.floor(Math.random() * 100) + 1;
      const guesses = document.querySelector('.guesses');
      const lastResult = document.querySelector('.lastResult');
      const lowOrHi = document.querySelector('.lowOrHi');
      const guessSubmit = document.querySelector('.guessSubmit');
      const guessField = document.querySelector('.guessField');
      let guessCount = 1;
      let resetButton;

但我有这个错误

有人可以帮我调试一下并使用https://github.com/mdn/learning-area/blob/master/javascript/introduction-to-js-1/first-splash/number-guessing-game 中的代码。我的机器人的html ？我来试试它是如何工作的，谢谢

好吧，你不能使用

      const guesses = document.querySelector('.guesses');
      const lastResult = document.querySelector('.lastResult');
      const lowOrHi = document.querySelector('.lowOrHi');
      const guessSubmit = document.querySelector('.guessSubmit');
      const guessField = document.querySelector('.guessField');

因为“文档”可以在支持 HTML 的 javascript 文件中使用。

您可以在https://discord.js.org上搜索它的替代品，因为它可能会有所帮助。我也会检查自己。

我实际上无法理解您到底想在那里做什么，您是想让用户（执行命令的人）猜测数字，还是希望机器人通过机器人猜测用户的数量.
