Question

这些天我正在学习引导程序。我正在开发主页。但是旋转木马没有用。请检查代码，并告诉我代码中缺少的内容。我只是从w3school复制粘贴轮播代码。我不知道我在哪里。如果有人可以在这方面帮助我，那就太好了。

您可能尚未下载引导程序样式表或javascript资产。该代码很好，因为您提到您直接从w3schools复制并粘贴了代码。

您需要下载以下文件并将其添加到您的文件夹中：

css / bootstrap.min.css js / bootstrap.min.js

OR

您可以将以下内容粘贴到.get(index)标记中：

$()

您可以在<head>标签的末尾添加以下内容：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

希望有帮助！
