为什么这个 Bootstrap 手风琴示例无法在我的页面上运行？

问题描述 投票：0回答：2

我是 Twitter Bootstrap 的新手，在尝试实现手风琴时遇到一些问题，如官方文档示例所示：http://getbootstrap.com/javascript/#collapse-example-accordion

我刚刚将之前的 HTML 代码复制并粘贴到我的页面中，我看到了手风琴内容，但我发现第一个面板已展开，其他 2 个面板已折叠。问题是我无法在这些面板上进行交互。如果我单击第一个面板，它不会折叠，如果我单击 2-3 个面板，它不会展开。

所以，这是我的页面内容：

<!DOCTYPE html>
<html>
<head>
<link href="<c:url value="resources/css/style.css" />" rel="stylesheet">

<link href="<c:url value="resources/css/bootstrap.css" />" rel="stylesheet">
<link href="<c:url value="resources/css/bootstrap-theme.css" />" rel="stylesheet">

<script src="<c:url value="resources/js/bootstrap.js" />"></script>

<title>Home</title>
</head>

<body>

    <section>
    <div class="container alignLeft">
    
        <div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true">

                </a>
              </h4>
            </div>
            <div id="collapseOne" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingOne">

    </section>

</body>
</html>

如您所见，我已正确包含 bootstrap.css 文件和 bootstrap.js 文件。

我错过了什么？我怎样才能解决这个问题并获得一个可用的手风琴？

需要在代码中包含实际的 jQuery 库。

将其放入您的 

head
:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

首先你必须包含脚本 jQuery（功能丰富的 JavaScript 库）位于 bootstrap 脚本之前，用于使任何内容都能与 bootstrap 配合使用。

以下是如何通过在 bootstrap 脚本之前包含最新版本的 jQuery 来使其工作。

<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="<c:url value="resources/js/bootstrap.js" />"></script>

您可能还想检查是否要使整个面板可单击，或者只是标题中的标题部分（当前情况）。
