javascript - 导航栏立即跳转到顶部

标签 javascript jquery html css

编辑:抱歉,这似乎是离线托管网站的问题。将所有内容转移到域后,我遇到的问题不再是问题。尽管它确实提出了一个问题,即为什么通过将所有文件保存在桌面上的文件夹中而不是通过主机运行它来通过同一浏览器加载不正确。

我正在尝试开发的网站有一个相当奇怪的问题。每当我对页面进行一次更改时,大约 75% 的时间在尝试正常加载它时导航栏都会出错。除非您在浏览器上点击“最大化窗口”按钮两次,否则导航栏将不再保留其预期位置并在滚动时立即跳到顶部。在两次按下最大化窗口按钮后尝试它时,它可以顺利运行。这是我当前的 HTML、CSS 和 JS。请随意忽略我的注释标签中的讽刺,以及该页面大部分不完整的事实。我只是想在继续之前解决一些问题。

您还没有在 href 中指定您的目标链接。

<li><a href="#">Link 1</a></li>
                <li><a href="#">Link 2</a></li>
                <li><a href="#">Link 3</a></li>
                <li><a href="#">Link 4</a></li>
                <li><a href="#">Link 5</a></li>
                <li><a href="#">Link 6</a></li>
                <li><a href="#">Link 7</a></li>
                <li><a href="#">Link 8</a></li>
                <li><a href="#">Link 9</a></li>

href="#"中的 '#' 符号没有指定 id 名称,但有一个相应的位置 - 页面顶部。单击带 href="#"的 anchor 会将滚动位置移动到顶部。

这就是它立即跳到顶部的原因。您必须指定您希望链接将用户引导至何处。
