在我正在创建的网站上，我有一个侧边栏，用作网站的导航菜单。左上角有一个按钮，可以打开和关闭滚动条。如果侧边栏有太多项目，则会出现滚动条以便滚动侧边栏。我遇到的问题是，打开和关闭的按钮不会与侧边栏一起滚动，而是在我滚动主页时滚动。有没有办法来解决这个问题？这是我迄今为止拥有的 HTML 和 JavaScript。

    transition: 0.2s;
    padding-top: 80px;
    filter: drop-shadow(5px 0px 1px black);
}

编辑 2:找到了一个解决方案 - 发布在下面。不幸的是，我需要 48 小时才能检查自己的解决方案，因此该线程将开放更长的时间。

最佳答案

好吧希望这就是你想要的。当它打开时，您需要在导航栏中有一个单独的滚动按钮，因为第一个按钮是基于整个屏幕的粘性按钮。

除此之外，我将按钮标签更改为 div，这样它们看起来就很漂亮。看看 onclick 函数是如何工作的。您设置按钮的方式正在寻找

函数 openNav(){...} 在你的脚本标签中，但它不在那里，祝你好运。
