我在dash.generalassemb.ly上做了一个教程，在那里我的代码可以工作，但是如果我在记事本++上运行chrome，javascript代码就不能工作

我的代码是：

  $('div').on('click', function() {
    $(this).toggleClass('show-description');

我的想法是，如果我点击一个菜单的内部，它会显示该食物的描述。怎么了？有任何帮助吗？

jquery未加载添加以下内容：

<script src="https://code.jquery.com/jquery-1.12.0.min.js"></script>

我在jsbin中验证了它的有效性

顺便说一句，如果javascript在chrome中不起作用，整个世界可能会陷入停滞，所以我对此表示怀疑。

是否存在/assets/jquery.js？控制台中是否存在任何错误？如果存在，请将script标记底部放到body标记中
