有人能帮我吗？我知道这里有一些错误。为什么我必须在页眉的末尾和页面的底部链接bootstrap.min.js。我试过一次使用一个，但它不起作用。下一件事是我希望当我加载页面和单击控制器时，carousel启动;而不仅仅是当我点击控制器的时候。

</body>

        <script type="text/javascript">// <![CDATA[
        var $ = jQuery.noConflict(); $(document).ready(function()  { $('#myCarousel').carousel({ interval: 3000, cycle: true }); });
        // ]]></script>
</html>

我刚刚设置了一个Fiddle，其中包含示例的carousel、jQuery版本2.1.3、bootstrap.js和bootstrap.css作为外部资源，以及用于初始化carousel的脚本

$('#myCarousel').carousel({
  interval: 3000,
  cycle: true
});

并且它正在工作--当页面加载并且控制器也在工作时它就开始了。它不工作可能是在jQuery之前加载 Bootstrap 的问题-- jQuery必须在 Bootstrap 之前包含。要检查是否是这种情况，请查看是否有任何错误/控制台消息，如“错误：Bootstrap的JavaScript需要jQuery”“。此外，您还包括2个不同的jQuery版本- 1.11.1和2.1.3。如果不需要，例如，对于一些依赖于旧jQuery版本的插件，尝试只加载最新版本。
另外，你把script标签放在结束body和html标签之间，这些标签可以工作，但是是无效的--参见link, script tags between and 了解细节。
作为使用不同jQuery版本的参考（如果确实需要），您可以选中http://api.jquery.com/jquery.noconflict/

你可以通过HTML中的data-interval标签来完成，将它插入<div id="myCarousel" class="carousel slide">中，看起来像这样：

<div id="myCarousel" class="carousel slide" data-interval="3000">

3000的值可以调整为较高的数值以降低速度，也可以调整为较低的数值以提高速度。

在包含的carousel div中添加自定义属性data-ride="carousel"。您可以选择添加data-interval="5000"以更改滑块更改持续时间（毫秒）。

这适用于Bootstrap v5.3。请阅读https://getbootstrap.com/docs/5.3/components/carousel/#methods
在carousel div中，将data-bs-ride设置为“carousel”。

<div id="carouselExample" class="carousel slide" data-bs-ride="carousel"> </id>

然后，body标记的所有最后部分写入以下代码：

<body>
      ...
        <script>
        const myCarouselElement = document.querySelector('#carouselExample')

        const carousel = new bootstrap.Carousel(myCarouselElement, {
           interval: 2000,
           touch: false
          })
        </script> 
    </body>
