Bootstrap Down - Not Down Down When id in URL
Bootstrap Down - Not Down Down When id in URL
提问于 2020-12-29 05:13:13
在我正在建设的网站上遇到了一个有趣的问题。当我到达一个包含id的url时，一个选项的下拉菜单停止工作。
举个例子，如果我在http://localhost/degs/serpstudentsinclass.php?id=3，如果我点击Admin下拉菜单，什么都不会发生。如果我单击返回到主页http://localhost/degs/index.php，管理下拉菜单开始工作没有问题。
在移动设备上工作时，这也增加了一个额外的问题。一旦你进入http://localhost/degs/serpstudentsinclass.php?id=3，你就完全失去了使用导航菜单的能力(因为现在由于屏幕尺寸的原因，它是一个完整的下拉菜单)。因此，您必须再次返回到index.php，然后菜单将再次开始工作。
有什么想法可以解释为什么会这样吗？
