javascript - 从数组中随机选择

Question

我正在尝试创建一个网站，它可以从数组中随机选择一些内容来造句。它应该从 objectArray 中选择一个随机项目，并通过 div 和 document.getElementById()

显示它

代码

<script>
    var objectArray = ["computer", "iphone", "duck", "candle", "oven", "sofa", "curtain", "blanket", "star", "piano", "turtle", "fluffiness", "door", "pillow", "funny face", "lamp", "healthy heart", "rainbow", "lamp", "clock", "coat", "just luck", "stop sign", "window"];
    var randObject = objectArray[Math.floor(Math.random() * objectArray.length)];

    document.getElementById("Objecto").innerHTML = "randObject";    
</script>

<center>
    <div id="Objecto"></div>
</center>

Answer 1

您将元素的 innerHTML 设置为字符串文字 "randObject"，而不是变量 randObject 的内容。改用这个:

document.getElementById("Objecto").innerHTML = randObject;

这是一个完整的片段:

var objectArray = ["computer", "iphone", "duck", "candle", "oven", "sofa", "curtain", "blanket", "star", "piano", "turtle", "fluffiness", "door", "pillow", "funny face", "lamp", "healthy heart", "rainbow", "lamp", "clock", "coat", "just luck", "stop sign", "window"];
var randObject = objectArray[Math.floor(Math.random() * objectArray.length)];

document.getElementById("Objecto").innerHTML = randObject;  

<center>
    <div id="Objecto"></div>
</center>
