Question

我不确定为什么这不起作用。当我点击链接时，数据假设显示在div中，但由于某种原因没有显示任何内容。任何人都有任何关于为什么这样做的建议？我不确定我的脚本是否设置正确。

我使用了错误的Jquery。我还需要将Jquery脚本放在页面底部。

<!-- Bootstrap core JavaScript

    <!-- Placed at the end of the document so the pages load faster -->

    <script src="http://code.jquery.com/jquery-2.1.3.min.js"></script>

   <script>
$('a').on('click', function() {

Answer 2

此外，为了运行任何您希望在页面完全加载后运行的代码，请养成围绕代码的习惯：

$( document ).ready(function() { ... });

所以对于你的页面，你会想要这个：

<script> $( document ).ready(function() { $('a').on('click', function() { var div_id = $(this).data('id'); $('.toggle_content').hide(); $('#' + div_id).toggle(); }); }); </script>

Answer 3

正如其他海报提到的那样，您需要将JQuery添加到您的项目中。

首先，在网页目录中创建一个名为“jquery”的文件夹。然后下载最新的JQuery js文件并将其保存在“jquery”目录中。

最新的JQuery（发布此评论时准确）就在这里。 http://code.jquery.com/jquery-2.1.3.min.js

之后，将此代码添加到其他链接所在的位置：

<link href="jquery/jquery-2.1.3.min.js" rel="stylesheet">

然后根据您的网页是在您的网站的根目录还是其中一个子目录中，根据需要调整您的href。

单击时尝试获取链接以显示div中的数据？
