javascript - 从数组中生成一个随机单词，然后将其打印到控制台日志中的 javascript 函数中

Question

我正在用 javascript 创建刽子手，我已经(我认为)成功地从函数中的数组生成了一个随机词，以检查它是否有效 我正在尝试将生成的词打印到控制台，但它没有似乎在工作 这是我的函数代码

    var word = function() //Random word is genereated from an array for the user to guess
{
  GameWordArray = new Array(7);
  GameWordArray[0] = "monitor";
  GameWordArray[1] = "program";
  GameWordArray[2] = "application";
  GameWordArray[3] = "keyboard";
  GameWordArray[4] = "javascript";
  GameWordArray[5] = "gaming";
  GameWordArray[6] = "network";
  randno = Math.floor(Math.random() * GameWordArray.length);
  document.write(GameWordArray[randno]);
  console.log(word);
}

提前致谢:)

这是关于 jsfiddle 的例子

var words = ["monitor", "program", "application", "keyboard", "javascript", "gaming", "network"];

var word = words[Math.floor(Math.random() * words.length)];

console.log(word);

document.getElementById("word").textContent = word;

并使其直接与您提供的代码相匹配:

var getRandomWord = function () {
    return words[Math.floor(Math.random() * words.length)];
};
