javascript - 如何从 Javascript 中先前选择的单词和短语列表中生成随机选择的单词或短语？

Question

对于我高中的计算机编程课程，我需要为学期末制作一个程序。目前我正在考虑做一个 Black Ops 2 加载生成器，为此我需要在 Javascript 中生成随机单词。我希望能够从单词列表中生成一个单词。所以如果我的单词列表是这样的：

Horse,
Pig,
Dog,
Cat,
Parrot,
Iguana,

然后我希望能够随机生成其中一个，然后将其显示在文本框中。

Answer 1

1. Put these items in an array. var array = ["Horse", "Pig", "Dog", "Cat", "Parrot", "Iguana"];
2. Generate a random number. var randInt = randomGenerator(0, array.length - 1); ( Generating random whole numbers in JavaScript in a specific range? )
3. Use the random number to get an item from the array. var item = array[randInt];
4. Use document.getElementById to get the textbox you want, and use .value = to set the textbox's value. var textbox = document.getElementById("textbox_id").value = randInt;

Answer 2

You just use Math.random() and index into the array of words.

var words = ['Horse',
'Pig',
'Dog',
'Cat',
'Parrot',
'Iguana'
];
function randomWord(arr) {
    return arr[Math.floor(Math.random() * arr.length)];
}

for(var x=0; x<20; x++)
    console.log(randomWord(words));
