html - 为什么手风琴在单击时不展开或折叠？
问题描述
我已经使用了它，因此我可以在单击 + 号时展开和折叠 div，但事实并非如此。它保持僵硬，不会膨胀或塌陷。我尝试添加和删除每个不需要的脚本，但它仍然不起作用。控制台也有错误：
未捕获的类型错误：$(...).slideReveal 不是函数

解决方案
您可能正在尝试在 DOM 可以安全操作之前执行该方法。根本问题是您已将所有脚本标签放在标签中，head而不是放在正文内容之后。尝试将您的电话包装在以下内容中：
$(function() {
// Handler for .ready() called.
})
参考：https ://api.jquery.com/ready/
与问题无关，但一些反馈是通过捆绑资源来减少页面上请求的资源数量。这会对最终用户的加载时间产生重大影响。
