原教程butterfly主题实现白天夜晚切换动画

写在最前

其实这个动画切换效果不是第一次看到了,最早看到是在一些volantis主题的用户博客那里,比如银河小徐那里,百度了一下也搜到过volantis相关的魔改教程,当时没当回事,直到在今年勇那里想到了相对完善的源码,不过他嵌入的不是很完美,按钮在一个比较尴尬的地方。和我的副标题重合了,js也是依赖于jquery的,和最新版butterfly去jquery的理念相悖,所以心血来潮对这个教程做下完善,顺便去jquery。

魔改步骤

  1. 新建[Blogroot]\themes\butterfly\layout\includes\custom\sun_moon.pug,这部分其实实质上就是一个svg文件,通过js操作它的旋转显隐,淡入淡出实现动画效果。
    svg(aria-hidden='true', style='position:absolute; overflow:hidden; width:0; height:0')
    symbol#icon-sun(viewBox='0 0 1024 1024')
    path(d='M960 512l-128 128v192h-192l-128 128-128-128H192v-192l-128-128 128-128V192h192l128-128 128 128h192v192z', fill='#FFD878', p-id='8420')

  2. 新建[Blogroot]\themes\butterfly\source\css\_layout\sun_moon.styl,
    .Cuteen_DarkSky,
    .Cuteen_DarkSky:before
    content ''
    position fixed
    left 0
    right 0
    top 0
    bottom 0
    z-index 88888888

    .Cuteen_DarkSky
    background linear-gradient(#feb8b0, #fef9db)
    &:before
    transition 2s ease all
    opacity 0
    background linear-gradient(#4c3f6d, #6c62bb, #93b1ed)

    .DarkMode
    .Cuteen_DarkSky
    &:before
    opacity 1

    .Cuteen_DarkPlanet
    z-index 99999999
    position fixed
    left -50%
    top -50%
    width 200%
    height 200%
    -webkit-animation CuteenPlanetMove 2s cubic-bezier(0.7, 0, 0, 1)
    animation CuteenPlanetMove 2s cubic-bezier(0.7, 0, 0, 1)
    transform-origin center bottom


    @-webkit-keyframes CuteenPlanetMove {
    0% {
    transform: rotate(0);
    }
    to {
    transform: rotate(360deg);
    }
    }
    @keyframes CuteenPlanetMove {
    0% {
    transform: rotate(0);
    }
    to {
    transform: rotate(360deg);
    }
    }
    .Cuteen_DarkPlanet
    &:after
    position absolute
    left 35%
    top 40%
    width 9.375rem
    height 9.375rem
    border-radius 50%
    content ''
    background linear-gradient(#fefefe, #fffbe8)

    .search
    span
    display none

    .menus_item
    a
    text-decoration none!important
    //按钮相关,对侧栏按钮做过魔改的可以调整这里的数值
    .icon-V
    padding 5px
  3. 新建[Blogroot]\themes\butterfly\source\js\sun_moon.js,去除了冗余代码,去jquery。感觉源代码做过混淆加密,好多三元运算一层套一层,看昏了都
    function switchNightMode() {
    document.querySelector('body').insertAdjacentHTML('beforeend', '<div class="Cuteen_DarkSky"><div class="Cuteen_DarkPlanet"></div></div>'),
    setTimeout(function() {
    document.querySelector('body').classList.contains('DarkMode') ? (document.querySelector('body').classList.remove('DarkMode'), localStorage.setItem('isDark', '0'), document.getElementById('modeicon').setAttribute('xlink:href', '#icon-moon')) : (document.querySelector('body').classList.add('DarkMode'), localStorage.setItem('isDark', '1'), document.getElementById('modeicon').setAttribute('xlink:href', '#icon-sun')),
    setTimeout(function() {
    document.getElementsByClassName('Cuteen_DarkSky')[0].style.transition = 'opacity 3s';
    document.getElementsByClassName('Cuteen_DarkSky')[0].style.opacity = '0';
    setTimeout(function() {
    document.getElementsByClassName('Cuteen_DarkSky')[0].remove();
    }, 1e3);
    }, 2e3)
    })
    const nowMode = document.documentElement.getAttribute('data-theme') === 'dark' ? 'dark' : 'light'
    if (nowMode === 'light') {
    activateDarkMode()
    saveToLocal.set('theme', 'dark', 2)
    GLOBAL_CONFIG.Snackbar !== undefined && btf.snackbarShow(GLOBAL_CONFIG.Snackbar.day_to_night)
    document.getElementById('modeicon').setAttribute('xlink:href', '#icon-sun')
    } else {
    activateLightMode()
    saveToLocal.set('theme', 'light', 2)
    document.querySelector('body').classList.add('DarkMode'), document.getElementById('modeicon').setAttribute('xlink:href', '#icon-moon')
    }
    // handle some cases
    typeof utterancesTheme === 'function' && utterancesTheme()
    typeof FB === 'object' && window.loadFBComment()
    window.DISQUS && document.getElementById('disqus_thread').children.length && setTimeout(() => window.disqusReset(), 200)
    }
  4. 修改[Blogroot]\themes\butterfly\layout\includes\head.pug,在文件末位加上一行:
      //- global config
    !=partial('includes/head/config', {}, {cache: true})

    include ./head/config_site.pug
    include ./head/noscript.pug

    !=fragment_cache('injectHeadJs', function(){return inject_head_js()})

    !=fragment_cache('injectHead', function(){return injectHtml(theme.inject.head)})
    + include ./custom/sun_moon.pug
  5. 修改[Blogroot]\themes\butterfly\layout\includes\rightside.pug,把原本的昼夜切换按钮替换掉,
      when 'translate'
    if translate.enable
    button#translateLink(type="button" title=_p('rightside.translate_title'))= translate.default
    when 'darkmode'
    if darkmode.enable && darkmode.button
    - button#darkmode(type="button" title=_p('rightside.night_mode_title'))
    - i.fas.fa-adjust
    + a.icon-V.hidden(onclick='switchNightMode()', title=_p('rightside.night_mode_title'))
    + svg(width='25', height='25', viewBox='0 0 1024 1024')
    + use#modeicon(xlink:href='#icon-moon')
  6. 修改[Blogroot]\_config.butterfly.yml,引入一下js,
    inject:
    head:
    bottome:
    - <script src="/js/sun_moon.js" async></script>
  7. 具体效果就自己切换下夜间模式看看吧。
