Butterfly 主题自带的 Loading 效果(两个嵌套矩形旋转盒子)略显单调并且不炫酷,今天手动添加几款比较自然好看的加载动画。

本教程参考了文末两位博主,特点在于:

  1. 可以根据配置项内的指定选项加载对应样式。
  2. 不选的样式不加载,有效节省资源。
  3. 优化了代码结构,方便读者融会贯通以后,自行添加其他加载动画。
  4. 内容支持自定义图片(png,jpg,gif均可)作为加载动画

OK,话不多说,魔改开始!

一、修改loading.pug

修改[Blogroot]\themes\butterfly\layout\includes\loading\loading.pug,下面代码中提供了多种款式,算上默认的旋转盒子加载动画,一共有7种,读者可以根据代码结构自行改写移除不需要的内容。

修改前(主题默认旋转盒子):

#loading-box
.loading-left-bg
.loading-right-bg
.spinner-box
.configure-border-1
.configure-core
.configure-border-2
.configure-core
.loading-word= _p('loading')

魔改后:

if theme.preloader.enable
case theme.preloader.load_style
when 'gear'
include ./load_style/gear.pug
when 'ironheart'
include ./load_style/ironheart.pug
when 'scarecrow'
include ./load_style/scarecrow.pug
when 'triangles'
include ./load_style/triangles.pug
when 'wizard'
include ./load_style/wizard.pug
when 'image'
include ./load_style/image.pug
default
include ./load_style/default.pug

此处第一行的if用于判断preloader功能是否打开。下面的casewhen则是根据配置项的内容加载指定的页面元素。default表示默认使用butterfly自带的旋转盒子动画。


二、创建动画结构模板文件夹

新建动画结构模板存放的文件夹,如无特别提示,所有动画模板均存放在[Blogroot]\themes\butterfly\layout\includes\loading\load_style\目录下。

1. default

新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\default.pug

这是之前默认的旋转盒子动画。

@keyframes configure-clockwise
0%
transform: rotate(0)

25%
transform: rotate(90deg)

100%
transform: rotate(360deg)

transform: rotate(-45deg)

50%

if hexo-config('preloader.enable')
if hexo-config('preloader.load_style') == 'gear'
@import './_load_style/gear'
else if hexo-config('preloader.load_style') == 'ironheart'
@import './_load_style/ironheart'
else if hexo-config('preloader.load_style') == 'scarecrow'
@import './_load_style/scarecrow'
else if hexo-config('preloader.load_style') == 'triangles'
@import './_load_style/triangles'
else if hexo-config('preloader.load_style') == 'wizard'
@import './_load_style/wizard'
else if hexo-config('preloader.load_style') == 'image'
@import './_load_style/image'
else
@import './_load_style/default'

几个if的判断机制与loading.pug类似,都是根据配置项来决定加载的样式。且默认使用旋转盒子动画。


四、创建动画样式模板文件夹

新建动画样式模板存放的文件夹,如无特别提示,所有动画样式均存放在[Blogroot]\themes\butterfly\source\css\_load_style\目录下

1. default

新建[Blogroot]\themes\butterfly\source\css\_load_style\default.styl

五、修改layout.pug

修改[Blogroot]\themes\butterfly\layout\includes\layout.pug

以适配接下来需要添加的配置项。

【注意】butterfly主题v3.6.0及之后版本里,该文件代码稍有不同(如下所示),但修改的东西都是一样的。该部分代码在文件的最上方大概10行左右的位置。
红色-代表需删除的代码行
绿色+代表需添加的代码行

  • butterfly_v3.0.0-v3.5.1

    1
    2
    3
    4
        body
    - if theme.preloader
    + if theme.preloader.enable
    !=partial('includes/loading/loading', {}, {cache:theme.fragment_cache})
  • butterfly_v3.6.0+

    1
    2
    3
    4
        body
    - if theme.preloader
    + if theme.preloader.enable
    !=partial('includes/loading/loading', {}, {cache: true})

六、修改var.styl

修改[Blogroot]\themes\butterfly\source\css\var.styl

添加自定义修改背景色的配置项。(大概98行的位置)

1
2
3
4
      // preloader
- $preloader-bg = #37474f
+ $preloader-bg = hexo-config('preloader.enable') && hexo-config('preloader.load_color') ? convert(hexo-config('preloader.load_color')) : #37474f
$preloader-word-color = #fff

七、修改_config.butterfly.yml

修改 [Blogroot]\_config.butterfly.yml 的 preloader 配置项。

有些版本的主题配置文件是[Blogroot]\themes\butterfly\_config.yml

修改前的默认代码:

1
2
# Loading Animation (加載動畫)加载动画
preloader: true #false

需要删改的代码:

1
2
3
4
5
6
7
    # Loading Animation (加載動畫)
- preloader: true
+ preloader:
+ enable: true # true|false
+ load_color: '#000000' # '#37474f'
+ load_style: wizard # default|gear|ironheart|scarecrow|triangles|wizard|image
+ load_image: # url

修改后:

1
2
3
4
5
6
# Loading Animation (加載動畫)加载动画
preloader:
enable: true # true|false
load_color: '#000000' # '#37474f'
load_style: wizard # default|gear|ironheart|scarecrow|triangles|wizard|image
load_image: # url

【配置项参数说明】:

  1. enable:控制加载动画的开关,取值有truefalsetrue开启,false关闭。
  2. load_color:该配置项为自定义加载动画背景颜色。默认值为#37474f,使用时注意用单引号''包起来,不然会被识别成注释符。这个配置项最大的作用是配合load_image使用的图片的背景色,可以用取色器提取自定义图片的主要色调,以达到图片和背景融为一体的效果。
  3. load_style:控制加载动画的样式,目前提供七种类型。预览见步骤2。
    • default是主题原版的盒子加载动画
    • gear是旋转齿轮加载动画
    • ironheart是钢铁侠核心加载动画
    • scarecrow是稻草人跳动加载动画
    • triangles是旋转三角加载动画
    • wizard是巫师施法加载动画
    • image为自定义添加静态图片或gif作为加载动画。
  4. load_image:该配置项的生效前提是load_style设置为image,内容填写图床链接或者本地相对地址。

熟悉魔改思路以后可以自定义添加更多更多样式,按照本教程的思路,在编译时只会加载选择的加载动画的对应样式,所以不用担心资源占用过多的问题。

最后执行 Hexo 命令三连,hexo cleanhexo ghexo s,即可看到效果


八、夜间模式匹配(非必要)

此项为非必要修改项,主要是为了避免使用image主题的加载动画时,切换夜间模式后,背景色被强制覆盖为黑色,。(说白了就是治疗强迫症

修改 [Blogroot]\themes\butterfly\source\css\_mode\darkmode.styl

第10行的 --preloader-bg: darken(#121212, 2)

1
2
3
4
5
6
    --search-input-color: alpha(#FFFFFF, .7)
--search-result-title: alpha(#FFFFFF, .9)
- --preloader-bg: darken(#121212, 2)
+ --preloader-bg: darken(#ca3b3e, -2)
--preloader-color: alpha(#FFFFFF, .7)
--tab-border-color: #2c2c2c

其中#ca3b3e是设置为image主题时,切换为夜间模式后,自定义图片的背景色值。(切换夜间模式时,整个页面会降低色调,所以连带着自定义图片的色值也变暗,需要重新取值。)


九、【问题解答】

(以下解答来源于 Akilar 博客教程评论区)

1. 超时自动结束

很多同学表示添加了加载动画以后加载半天,只能看动画却进不了站。这点主要是因为加载动画的关闭与否是与网站加载状态的load的返回值决定的,而网站加载完成与否这个概念是很暧昧的,如果加装了pwa,清空缓存后再次加载的内容可能比想象的要多。以下提供两种方案,一个超时自动结束,一个手动点击结束。两者兼容,你可以同时使用达到多重保险。

可以给加载动画设置一个settimeout()的函数来达到伪·加载完毕的效果,即超时了自动关闭加载动画,即使页面还在加载。得益于loading-js使用的是原生js,所以可以给script添加async属性实现异步加载,以免阻塞后续HTML渲染。仅仅需要给控制加载动画开关的loading-js.pug添加两行代码即可。

-   script.
+ script(async).
var preloader = {
endLoading: () => {
document.body.style.overflow = 'auto';
document.getElementById('loading-box').classList.add("loaded")
},
initLoading: () => {
document.body.style.overflow = '';
document.getElementById('loading-box').classList.remove("loaded")

}
}
window.addEventListener('load',()=> {preloader.endLoading()})
+ setTimeout(function(){preloader.endLoading();}, 5000);

其中5000的单位是ms,代表你设置的最大容忍时间。可以自行修改。

这样一来,如果网站在五秒内加载完成,则优先执行window.addEventListener(‘load’,()=> {preloader.endLoading()}),如果超过5秒,则执行 setTimeout(function(){preloader.endLoading();}, 5000);,两者互不干扰。可喜可贺,可喜可贺。

2. 手动点击结束

给整个 loading-box 添加一个点击动作,点击动画就能结束。
同样是修改[Blogroot]\themes\butterfly\layout\includes\loading\loading-js.pug

document.getElementById('loading-box').classList.remove("loaded")

}
}
window.addEventListener('load',()=> {preloader.endLoading()})
+ document.getElementById('loading-box').addEventListener('click',()=> {preloader.endLoading()})

3. 去除左右帷幕拉开效果

  • 【问】求助,设置了加载动画,每次转页的时候都会出现一个白色的拉开动画,怎么去除这个左右拉开的动画

  • 【答】Akilar:找到你这个加载动画对应的pug文件,把这两行删了。

    1
    2
    .loading-left-bg

4. 延长动画时间

  • 【问】怎么弄才可以让它至少加载多少秒,我感觉加载一下就进去了,实际上没加载完.

  • 【答】Akilar:看补充内容里的超时自动结束,稍微改写下就好了,因为实质上控制关闭的就是preloader.endloading()这个函数方法,你把动作监听改成计时器就行。

endLoading: () => {
document.body.style.overflow = 'auto';
document.getElementById('loading-box').classList.add("loaded")
},
initLoading: () => {
document.body.style.overflow = '';
document.getElementById('loading-box').classList.remove("loaded")

}
}
- window.addEventListener('load',()=> {preloader.endLoading()})
+ setTimeout(function(){preloader.endLoading();}, 5000);

5. 动画加载太快

  • 【问】按照教程设置了,加载太快 请问如何设置?

  • 【答】Akilar:加载太快不是好事情吗?加载动画的初衷就是为了在页面未加载完全时提供一下遮羞的作用。要是单纯为了多欣赏一会加载动画而去刻意延长时间不是本末倒置了吗

  • 【答】Akilar:如果是指开屏效果太快,在loading.styl里找到这个,1.0s就是开屏的持续时间。但是这个又取决于加载动画完成的时间,要是页面加载太快,他会很快的隐藏到底层,而显现不出效果。说到底没有那个可以延长的必要啊

    transition all 1.0s
    transform translate(-100%, 0)
    .loading-right-bg
    transition all 1.0s
    transform translate(100%, 0)

6. 动画过快,图片还没加载完

  • 【问】我也觉得加载太快了,我不知道加载完成不怎么判定的,但是我的加载动画之后背景图会有一小会儿只显示一半(就跟卡住了一样)。如果我把背景图放到本地,hexo s测试加载本地图片就不会这样。说明还是因为图片没有加载完成。所以有什么办法强制多加载一会儿呢?比如至少加载一两秒之类的

  • 【答】Akilar:这是伪需求啊,图片加载不完是因为图片过大或者网络环境不好。加载动画的绝对时间控制可以用超时函数实现不假,把网页监听动作改成单纯的超时函数就可以,5000的单位是毫秒。

    - window.addEventListener('load',()=> {preloader.endLoading()})
    + setTimeout(function(){preloader.endLoading();}, 5000);

    但是我还是不建议你这么做。这样就失去加载动画的本质意义了。

7. 淡出动画

加载动画淡出效果,让网站更丝滑

script(async).
var preloader = {
endLoading: () => {
document.body.style.overflow = 'auto';
document.getElementById('loading-box').style.transition = 'opacity 3s ease 0s'
document.getElementById('loading-box').style.opacity = '0'
setTimeout(function(){
document.getElementById('loading-box').classList.add("loaded")
}, 3000);
},
initLoading: () => {
document.body.style.overflow = '';
document.getElementById('loading-box').style.transition = '';
document.getElementById('loading-box').style.opacity = '1'
document.getElementById('loading-box').classList.remove("loaded")

}
}
window.addEventListener('load',()=> {preloader.endLoading()})
setTimeout(function(){preloader.endLoading();}, 3000);

百里飞洋:可以在主题配置文件中搜索pjax,将其enable参数设置为true。开启Pjax能够实现页面的局部刷新而非整体重载资源,在一定程度上能够减少网站反复加载重复资源,从而优化访问体验,让网站更丝滑。(当然,由于网站变“快”了,加载动画的出现时间长度会随之减少。所以,如果你不开启Pjax就可以多“收获”1、2秒的动画时间哈哈)


十、【补充动画】

除了上面教程中的那些动画效果,下面我再进行一些补充,想添加的同学请自行添加。需完成上面步骤,才能进行以下补充动画的添加操作

(1)黏性加载动画

新建 [Blogroot]\themes\butterfly\layout\includes\loading\load_style\gooey.pug

}

.blob-2 {
left: 80%;
animation: osc-r 2.5s ease infinite;
background: #0ff;
}
}
}

/* Animations */
@keyframes osc-l {
0% {
left: 20%;
}

50% {
left: 50%;
}

100% {
left: 20%;
}
}

@keyframes osc-r {
0% {
left: 80%;
}

50% {
left: 50%;
}

100% {
left: 80%;
}
}

修改 [Blogroot]\_config.butterfly.yml 的 preloader 配置项。

有些版本的主题配置文件是[Blogroot]\themes\butterfly\_config.yml

# Loading Animation (加載動畫)加载动画
preloader:
enable: true # true|false
load_color: 'radial-gradient(#353c44, #222931)' #'#000000' # '#37474f'
load_style: gooey # default|gear|ironheart|scarecrow|triangles|wizard|image|gooey
load_image: # url

别忘了在loading.pugloading.styl中模仿上面步骤添加对应代码。

最后执行 Hexo 命令三连,hexo cleanhexo ghexo s,即可看到效果
