javascript 数组仅在未完全充满内容时才有效

Question

我有一个充满引号的数组，加载时会显示随机引号。我遇到的问题是，当我只加载 2 个引号时，一切正常，但当我添加整个列表时，它不再运行。

这是有效的代码-

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


<script type="text/javascript">

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>

上面的内容按预期工作，但是当我添加其余引号(如下所示)时，脚本不再工作。

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

<script type="text/javascript">
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>

JavaScript 字符串中不能有换行符。您需要更改此设置:

"str part
 the rest"

对此:

"str part\nthe rest"

或

"str part\n"
+ "the rest"

您应该检查 JavaScript 控制台是否有错误；这可以帮助您调试
