导航锚标签不起作用，但为什么？答案

【问题标题】：Navigation anchor tags not working, but why?导航锚标签不起作用，但为什么？
【发布时间】：2017-07-22 07:26:42
【问题描述】：

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

第 1 部分 - 关于 index.html

但是，当单击“博客”导航项时，它应该转到博客.html。在.header-nav 我有以下<li><a href="blog.html">Blog</a></li> 但不工作。在浏览器中，它显示链接被定向到 blog.html 但没有去。

第 2 部分 - 在 Blog.html 上

打开，blog.html，我已经从 index.html 复制了 .header-nav 代码 - 但是当我点击“关于”时，应该转到主页并向下滚动到 about div - 不是！ 即使代码在 index.html 页面中运行。 我们将不胜感激任何想法！

【问题讨论】：

标签： javascript html css navigation onepage-scroll

【解决方案1】：

您的 javascript - 特别是这里：

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

正在阻止页面更改。这看起来像您正在改编一个“单页”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 放在您想要平滑向下滚动页面的链接上

【讨论】：

是的，完美运行。但是第 2 部分的问题仍然存在 - 在 blog.html 上，当我单击关于页面时，它应该转到 index.html，然后是 #about-View div。有什么想法吗？
您需要将链接更改为：About - 这会指示浏览器转到索引.html 页面 THEN 到 about-View ID
是的，我已经在 @mayersdesign 尝试过，它指向正确的路径，但是当我点击时不走。
我基本上有这个：
关于

是的，没错，虽然它在到达索引页面时不会滚动（这可能会很烦人） - 它会直接跳转到“关于”部分。
