Question

我正试图在每次刷新时从列表中生成一个新的引用。出于某种原因，我无法在div中显示引号，我不确定原因。

任何帮助将不胜感激！

<div id="quotes">

<script>
var quotes = new Array();
quotes[0] = "<i>Quote 1</i><br><b>Author</b>";
quotes[1] = "<i>Quote 2</i><br><b>Author</b>";

var random = Math.ceil (Math.random() * quotes.length) - 1;
$('quotes').set('html', quotes[random]);
</script>

</div>

我已经更新了我的代码，感谢大家对此的帮助 -

<div id="quotes"></div>

<script>
var quotes = [
"<i>"Some people feel the rain. Others just get wet."</i><br><b>Bob Marley/b>",
"<i>“Do not pray for an easy life, pray for the strength to endure a                    difficult one.”</i><br><b>Bruce Lee</b>",

];

document.getElementById('quotes').innerHTML = quotes[Math.floor(Math.random() * quotes.length)];
</script>

出于某种原因，div仍在加载，没有任何内容想法。

这是我的报价内部的引用搞砸了。谢谢大家的帮助!!

Answer 1

不再需要任何库，这使得代码变得更加容易。

<div id="quotes"></div>
<script>
var quotes = [
    "<i>Quote 1</i><br><b>Author</b>",
    "<i>Quote 2</i><br><b>Author</b>"
];

document.getElementById('quotes').innerHTML =
                                   quotes[Math.floor(Math.random() * quotes.length)];
</script>

Answer 2

编辑：没关系，似乎MooTools中的$确实应该返回标识为quotes的元素。如果你想在没有框架的情况下做同样的事情，可以使用document.getElementById('quotes').innerHTML = quotes[random]。

您的$正在尝试查找名为<quotes>的元素，而不是ID为“引号”的元素（假设它使用了像jQuery这样的CSS选择器）。使用$('#quotes')应该修复它。

其他一些事情：你可以用更简洁的方式编写数组：

quotes = [
  "<i>Quote 1</i><br><b>Author</b>",
  "<i>Quote 2</i><br><b>Author</b>"
];

此外，您可以使用Math.floor代替Math.ceil作为随机值，然后最后不需要- 1。
