前言

在写系列博文时对于某一篇文章的寻找过程会比较繁琐(对于博主而言自然会简单些,但是对于访客来讲就没那么轻松),因此参考Akilar的博文弄了一个置顶轮播图。可以把系列博文的链接汇总起来做一个索引,放置在轮播图中。这样既可以展示博主想对外展示的内容,又方便快速进行文章跳转。

效果可以在博客首页查看。

本篇教程会涉及大量源码的改动,对缩进有严格要求。如果需要,可以移步下方链接至Akilar的博客教程去下载源码。

操作

  1. \themes\butterfly\layout\includes路径下创建文件sliderbar.pug,并将以下内容写入该文件:

    1
    2
    3
    4
    5
    6
    7
    8
    9

    .blog-slider.swiper-container-fade.swiper-container-horizontal#swiper_container
    .blog-slider__wrp.swiper-wrapper(style='transition-duration: 0ms;')
    if site.data.slider
    each i in site.data.slider
    .blog-slider__item.swiper-slide(style='width: 750px; opacity: 1; transform: translate3d(0px, 0px, 0px); transition-duration: 0ms;')
    a.blog-slider__img(href=url_for(i.link) alt='')|
    img(width='48' height='48' src=url_for(i.cover) onerror=`this.onerror=null;this.src='` + url_for(theme.error_img.post_page) + `'`, alt='')
    .blog-slider__content
    span.blog-slider__code= i.timeline
    a.blog-slider__title(href=url_for(i.link) alt='')= i.title
    .blog-slider__text= i.description
    a.blog-slider__button(href=url_for(i.link) alt='')= i.button
    .blog-slider__pagination.swiper-pagination-clickable.swiper-pagination-bullets
    script(defer src=url_for(theme.CDN.swiper_js))
    script(defer data-pjax src=url_for(theme.CDN.swiper_init))
  2. 在路径\themes\butterfly\layout修改文件index.pug,添加以下两行代码(注意缩进)引入轮播图板块。

    注意在butterfly_v3.6.0中取消了缓存配置,需要将{cache:theme.fragment_cache}改为{cache: true}

    1
    2
    .recent-post-item(style='height:auto;width:100%;')
    !=partial('includes/sliderbar', {}, {cache:theme.fragment_cache})

  3. \themes\butterfly\source\js路径下,新建文件swiper_init.js,并将以下代码写入:

    1
    2

    var swiper = new Swiper('.blog-slider', {
    passiveListeners: true,
    spaceBetween: 30,
    effect: 'fade',
    loop: true,
    autoplay: {
    disableOnInteraction: true,
    delay: 3000
    },
    mousewheel: false,
    // autoHeight: true,
    pagination: {
    el: '.blog-slider__pagination',
    clickable: true,
    }
    });

    var comtainer = document.getElementById('swiper_container');
    comtainer.onmouseenter = function() {
    swiper.autoplay.stop();
    };
    comtainer.onmouseleave = function() {
    swiper.autoplay.start();
    }
  4. \themes\butterfly\source\css\_layout路径下,创建文件swiperstyle.styl,并将以下代码写入:

  5. 配置CDN依赖项。

    • 修改文件_config.butterfly.yml,在CDN模块下添加如下代码:

      1
      2
      3
      4
      # 首页轮播图
      swiper_js: https://cdnjs.cloudflare.com/ajax/libs/Swiper/4.1.6/js/swiper.min.js
      swiper_css: https://cdnjs.cloudflare.com/ajax/libs/Swiper/4.1.6/css/swiper.min.css
      swiper_init: /js/swiper_init.js

    • 在路径\themes\butterfly\source\css下找到文件index.styl,在最上方添加如下代码:

      1
      @import url(hexo-config('CDN.swiper_css'))

  6. 在路径\source\_data下创建文件slider.yml,在里面填写想要置顶文章的信息

个人觉得还蛮实用的一个修改。
