Mobile Navbar赢得'单击时不显示

Mobile Navbar won't show when clicked

本文关键字：单击 显示 Navbar 赢得 Mobile      更新时间：2023-09-26

当以移动屏幕分辨率查看并选择移动导航图标栏时，什么都不会发生。期望的效果是在移动设备中使用相同的主导航。我已经确保我的数据目标（mobile_nav）匹配，这个标记看起来不错，但对Bootstrap来说是新的。感谢您的帮助！

Bootstrap需要jQuery才能工作，您应该在HTML:中的Bootstrap JS之前包含它

<!-- JQuery -->    
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<!-- Latest compiled and minified JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
