导航锚标签不起作用，但为什么呢？

Question

所以我有一个两页的网站。主页有一个单页导航，即当单击“about”时，它会向下滚动到“about”div。

第 1 部分 - 关于 index.html

然而，当 'blog' 导航项被点击时，它应该转到 blog.html。在 .header-nav 中，我有以下 <li><a href="blog.html">Blog</a></li> 但不工作。在浏览器中显示 link 被定向到 blog.html 但没有去。

第 2 部分 - 关于 Blog.html

在 blog.html，我已经 从 index.html 复制了 .header-nav 代码 - 但是当我点击 'about' 它时应该转到主页并向下滚动到大约 div - 它不是！ 即使代码在 index.html 页面中运行。 任何想法将不胜感激！

Answer 1

您的 javascript - 特别是此处：

    // prevent anchor tags for working (?)
    e.preventDefault();

正在阻止页面更改。这看起来你正在改编一个 "one page" 网站。

将该部分更改为：

$(".header-nav a.scrollLink").click(function(e) {
    // prevent anchor tags for working (?)
    e.preventDefault();
    var sectionID = e.currentTarget.id + "-View";
    $("html, body").animate({
        scrollTop: $("#" + sectionID).offset().top
    }, 1000)
})

...并将 calss scrollLink 放在您希望平滑向下滚动页面的链接上

导航锚标签不起作用，但为什么呢？

Navigation anchor tags not working, but why?

javascript

html

css

navigation

onepage-scroll
