安知鱼主题默认幻灯片切换的样式美化

作为一个博客也好，网站也罢，个人观点，幻灯片展示内容板块必不可少，安知鱼主题自带一个幻灯片切换效果，需要在主题配置文件中打开。

1.开启 swiper 幻灯片

在安知鱼主题的 _config.yml 配置文件中，搜索 swiper，会找到如下代码

swiper:
  enable: false
  swiper_css: https://npm.elemecdn.com/anzhiyu-theme-static@1.0.0/swiper/swiper.min.css #swiper css依赖
  swiper_js: https://npm.elemecdn.com/anzhiyu-theme-static@1.0.0/swiper/swiper.min.js #swiper js依赖

将里面 false 修改为 true，开启swiper幻灯片

swiper:
  enable: true
  swiper_css: https://npm.elemecdn.com/anzhiyu-theme-static@1.0.0/swiper/swiper.min.css #swiper css依赖
  swiper_js: https://npm.elemecdn.com/anzhiyu-theme-static@1.0.0/swiper/swiper.min.js #swiper js依赖

2.CSS样式修改

在 /themes/anzhiyu/source/css_extra/home_top/ 文件夹中，找到 swiperstyle.css 样式文件，这个文件调控着默认幻灯片的样式，直接复制下面的代码替换掉源代码，就可以实现我的截图效果，不需要额外引入 CSS 样式文件

主要是调整了 swiper 默认 分页器 的位置，原来的幻灯片分页器在右侧边栏上，我给他调整到了幻灯片底部。

3.修改幻灯片调用

默认幻灯片调用代码修改，需要在 /themes/anzhiyu/layout/includes/top/ 文件夹中，修改 top.pug 文件，涉及到文件对缩进有严格要求，可以使用下面的代码整体替换掉文件代码

我调整的调用顺序，是 标题 、时间 、文章简介，大家可以比对代码自己调整修改。

4.当前问题

4.1.基础性改变

仅仅是修改了 分页器 的位置，调整了 标题 、时间 、文章简介 调用顺序。

4.2.缺失弥补

没有添加幻灯片特有的 左右切换箭头 。

4.3.用旧舍新

调用的 swiper 文件都比较老旧，尝试着使用新版本 swiper 的 CSS 和 JS 文件都不成功，水平太菜，本着能跑就用的原则，这一点儿需要注意。

4.4.幻灯片调整的新增功能

主要是为了衬托 swiper 分页器的小圆点，不然显示不出来。

4.4.1.新增了背景颜色渐变

大家注意 pug 文件顶部的代码，如下

1
- const getRandomGradient = () => `linear-gradient(${Math.floor(Math.random()*360)}deg, rgb(${Math.floor(Math.random()*255)},${Math.floor(Math.random()*255)},${Math.floor(Math.random()*255)}), rgb(${Math.floor(Math.random()*255)},${Math.floor(Math.random()*255)},${Math.floor(Math.random()*255)}))`

代码调用为

1
.blog-slider__item.swiper-slide(style=`width: 100%; height: 100%; opacity: 1; transform: translate3d(0px, 0px, 0px); transition-duration: 0ms; background: ${getRandomGradient()};`)
4.4.2.增加了内容简介字数截取

大家注意 pug 文件顶部的代码，如下

1
- const truncateText = (text, maxLength) => !text ? '' : (text.length > maxLength ? text.substring(0, maxLength) + ' ...' : text)

幻灯片调用中，对内容简介的调用代码

1
.blog-slider__text= truncateText(item.description ? item.description : expert, 80)

在这里输入调用的内容简介的字数；

4.4.3.幻灯片调用缩略图当背景图片

无论是采用渐变背景，还是当前文章的缩略图当背景，都是为了衬托 swiper 分页器的小圆点，否则小圆点不突出，当前是 蓝白 搭配。

1
.blog-slider__item.swiper-slide(style=`width: 100%; height: 100%; opacity: 1; transform: translate3d(0px, 0px, 0px); transition-duration: 0ms; ${item.cover ? `background: url('${item.cover}');` : ''}`)

如果仅仅是拿文章的缩略图当做背景图片，不需要显示额外图片，只需要把

1
2
a.blog-slider__img(href=item.path, title=item.title)
  img(width='48' height='48'  src=item.cover alt='图片' onerror=`this.src=` + error_img + `; this.onerror = null;`)

中的 src=item.cover 删除掉就可以，不过我没有测试。后续更新仍然在努力中。

希望技术好的前端帮我解决一个问题，就是如何整合新的 swiper 文件，我测试的时候，如果使用新的 swiper 文件，即刻说说乱套。

5.结束语

最后 Hexo 三板斧，就可以在页面侧边栏查看效果。欢迎大家在评论区给予指正，让我们共同打造快节奏时代，不受算法牵制的属于我们自己的小空间！
