好吧,我开始写这个网页了,我遇到了一些我无法找到答案的问题。
我所拥有的代码的基本思想是:
- 鼠标在“浏览网页”上时打开菜单
- 鼠标悬停时菜单“链接”突出显示
- 当用户单击菜单项时,菜单将移动到页面顶部,并且“链接”保持突出显示,直到用户单击不同的链接。
- 当菜单移到顶部时,下面会打开一个 div,显示该部分的内容。
我有两个主要问题。首先,每当我单击菜单项时,它都不会保持突出显示(数字 3)。其次,在单击(数字 4)后,div 没有在菜单下方打开。我将不胜感激对这些问题的任何见解。
我包含了我所有的代码,因为我相信它都与我的问题有关。

非常感谢你的帮助。
第二个问题:当指向菜单中的文本时,如何防止光标从指针上改变?
再次感谢!
