导航栏美化 | JayHrn

看到了那么多好看的导航栏，感觉Heo的非常的好看，一开始想直接f12取到，但是发现怎么都实现不了，甚至导航栏直接寄了（应该是f12的技能有待提示吧）。没办法，后来也发现了类似的导航栏，借鉴了Eurkon的博客，两者十分的接近，并且实现了。

刚好最近有人问导航栏怎么实现的，那么就开始吧！

教程

修改themes/butterfly/layout/includes/header/nav.pug，直接全部覆盖

nav#nav
  #nav-group
    span#blog_name
      a#site-name(href="/" title="返回博客主页")
        span JAYHRN
    span#page_name
      a#page-name-text(title=_p("rightside.back_to_top") onclick="btf.scrollToDest(0,500)")
        span #[=config.title]

    #menus
      !=partial('includes/header/menu_item', {}, {cache: true})

    #hotkey
      if (theme.algolia_search.enable || theme.local_search.enable)
        #search-button
          a.site-page.social-icon.search(title=_p('search.title'))
            i.ri-search-eye-line
      #randompost-button
        a.site-page(title="随机文章" onclick="toRandomPost()")
          i.ri-subway-fill
      if (theme.darkmode.enable && theme.darkmode.button)
        #mode-button
          a.site-page(title=_p('rightside.night_mode_title') onclick="switchDarkMode()")
            i.ri-sun-fill
      #top-button
        a.site-page(title=_p("rightside.back_to_top") onclick="btf.scrollToDest(0,500)")
          i.ri-plane-fill
      #toggle-menu
        a.site-page
          i.fas.fa-bars.fa-fw

引入导航栏图标，也可以自行换成其他的图标

引入js，实现获取主页标题或文章标题，引入到自定义js文件中，没有可以新建themes/butterfly/source/js/custom/custom.js文件

"" === GLOBAL_CONFIG_SITE.title.replace("JayHrn", "") ? document.getElementById("page-name-text").style.display = "none" : document.querySelector("#page-name-text>span").innerHTML = document.title.split(" | Jayhrn")[0];

其中JayHrn换成自己的网站名称

设置网页阅读进度，下方引入自定义js文件，没有可以新建themes/butterfly/source/js/custom/custom.js文件

var $percent = document.querySelector("#nav #hotkey #top-button a.site-page i");
$percent && window.addEventListener("scroll", (function () {
    let e = document.body.scrollHeight || document.documentElement.scrollHeight,
        t = window.innerHeight || document.documentElement.clientHeight;
    $percent.dataset.percent = ((document.body.scrollTop || document.documentElement.scrollTop) / (e - t) * 100).toFixed(0)
}));
