javascript - 使用 HTML5 和没有图像的 javascript 的 Windows 8 预加载器（加载图标）

Question

在查看 Windows 8 加载屏幕的屏幕时，我注意到一个简单的事情，有一个非常有趣的预加载器（或加载图标），它有一点重力/摇摆效果。我想使用 javascript 和 css 复制相同的内容，但我对 javascript 动画了解不多，因此想知道您是否可以给我一个方向，在那里我可以找到类似的示例。您还可以通过提供具有类似动画类型的代码片段来提供帮助。

任何帮助，将不胜感激。

Answer 1

检查网站CSSload。在这里，您可以在几秒钟内制作您的 CSS 加载器。我已经制作了 Windows 8 加载器，所以你可以在这里看到它。

@keyframes orbit {
   0% {
      opacity: 1;
      z-index:99;
      transform: rotate(180deg);
      animation-timing-function: ease-out;
   }

   7% {
      opacity: 1;
      transform: rotate(300deg);
      animation-timing-function: linear;
      origin:0%;
   }

   30% {
      opacity: 1;
      transform:rotate(410deg);
      animation-timing-function: ease-in-out;
      origin:7%;
   }

   39% {
      opacity: 1;
      transform: rotate(645deg);
      animation-timing-function: linear;
      origin:30%;
   }

   70% {
      opacity: 1;
      transform: rotate(770deg);
      animation-timing-function: ease-out;
      origin:39%;
   }

   75% {
      opacity: 1;
      transform: rotate(900deg);
      animation-timing-function: ease-out;
      origin:70%;
   }

   76% {
      opacity: 0;
      transform:rotate(900deg);
   }

   100% {
      opacity: 0;
      transform: rotate(900deg);
   }
}

或者，试试这个代码示例......

Answer 2

这是我没有 Javascript 的纯 CSS3 实现，其中我结合了 CSSload和Jan Rubio 的 codepen技术，以实现最少的标记和没有 id 选择器：

HTML：

<div class="loader">
   <div class="circle"></div>
   <div class="circle"></div>
   <div class="circle"></div>
   <div class="circle"></div>
   <div class="circle"></div>
</div>

CSS：

.loader { position: relative; width: 64px; height: 64px; }
.loader .circle { position: absolute; width: 61px; height: 61px; opacity: 0; -moz-transform: rotate(225deg); -moz-animation: orbit 7.15s infinite; -webkit-transform: rotate(225deg); -webkit-animation: orbit 7.15s infinite; -ms-transform: rotate(225deg); -ms-animation: orbit 7.15s infinite; -o-transform: rotate(225deg); -o-animation: orbit 7.15s infinite; transform: rotate(225deg); animation: orbit 7.15s infinite; }
.loader .circle:after { content:''; position: absolute; width: 8px; height: 8px; background: #04C5DE; left: 0px; top: 0px; -moz-border-radius: 8px; -webkit-border-radius: 8px; -ms-border-radius: 8px; -o-border-radius: 8px; border-radius: 8px; }

    100% { opacity: 0; -webkit-transform: rotate(900deg); }

Answer 3

我不确定，但也许这就是你想要的：

<progress style="color: white;" class="win-medium win-ring"></progress>

Answer 4

这是对 CSS3 中 Modern UI ProgressRing 动画的另一种看法。它基于已经提到的 Jan Rubio 的解决方案，并进行了一些调整（但仍需要调整）。

如果 codepen 不可用，请观看现场示例或使用以下代码：

HTML

<div class='progress-ring'>
  <div class='progress-ring__wrap'>
    <div class='progress-ring__circle'></div>
  </div>
  <div class='progress-ring__wrap'>
    <div class='progress-ring__circle'></div>
  </div>
  <div class='progress-ring__wrap'>
    <div class='progress-ring__circle'></div>
  </div>
  <div class='progress-ring__wrap'>
    <div class='progress-ring__circle'></div>
  </div>
  <div class='progress-ring__wrap'>
    <div class='progress-ring__circle'></div>
  </div>
</div>

CSS（少，无前缀）

body {background:#111}
@t:4000ms;
@d:40px;
@color:#ffffff;
.progress-ring {
  position: relative;
  padding-top: @d/5;
  width: @d;
  height: @d;
  margin: auto;

  .progress-ring__wrap {
    position: absolute;
      width: @d - 2;
      height: @d - 2;

    .progress-ring__circle {
      transform: rotate(225deg);
      animation-iteration-count: infinite;
      animation-name: orbit;
      animation-duration: @t;
      width: @d - 2;
      height: @d - 2;

      opacity: 0;

      &:after {
      content: '';
        position: absolute;
        width: @d/8;
        height: @d/8;
        border-radius: @d/8;
        box-shadow: 0px 0px 5% @color;
        background: @color; /* Pick a color */
      }
    }


    @r:-14deg;
    @m:30;
    &:nth-child(2) {
      transform:rotate(@r);
      .progress-ring__circle {  animation-delay: @t/@m; }
    }
    &:nth-child(3) {
      transform:rotate(@r*2);
      .progress-ring__circle {  animation-delay: @t/@m*2; }
    }
    &:nth-child(4) {
      transform:rotate(@r*3);
      .progress-ring__circle {  animation-delay: @t/@m*3; }
    }
    &:nth-child(5) {
      transform:rotate(@r*4);
      .progress-ring__circle {  animation-delay: @t/@m*4; }
    }
  }
}

@keyframes orbit { 
  0%   { transform:rotate(225deg); opacity: 1;
         animation-timing-function: ease-out; } 

  7%   { transform:rotate(345deg);
         animation-timing-function: linear; }

  35%   { transform:rotate(495deg);
          animation-timing-function: ease-in-out; }

  42%   { transform:rotate(690deg);
          animation-timing-function: linear; }

  70%   { transform:rotate(835deg); opacity: 1; 
         animation-timing-function: linear; }

  76% {opacity: 1;}

  77%   { transform:rotate(955deg);
         animation-timing-function: ease-in; }

  78% { transform:rotate(955deg); opacity: 0; }
  100% { transform:rotate(955deg); opacity: 0; } 
}

不确定 javascript，但您可以从http://preloaders.net/en/search/windows8下载

Answer 6

我发现你可以在 and 上找到一个类似的脚本C:\Windows\WinStore\WinStore.css，WinStore.htm只要打开Winstore.htm，你就会发现一个类似的环形加载动画，由 提供IE10，如果有人可以从 Windows Shell 转储动画信息...如果你用记事本看到，WinStore.css你会看到一些东西像这样：

splashProgress::-ms-fill
{
    animation-name: **-ms-ring**;
}

该变量是存储在 Windows Shell 中某处的动画信息吗？？？

我测试了在 Chrome 和 Firefox 中加载 HTML 页面，什么都没有，只是一个正常的加载栏。

对不起，我的英语不好。我来自阿根廷。
