我有一个需求，需要动态加载js文件，并通过SVG图标显示加载文件的进度。SVG图标将作为进度条，从下到上线性填充一种颜色。

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="79.36px" height="93.844px" viewBox="0 0 79.36 93.844">

  <path fill="transparent" stroke="black" d="M50,2C30-4,8,7,2,28c-6,20,5,42,26,48h0l-4,15l33-18c0-0,0-0,1-0l0-0l-0-0c8-4,15-12,17-22C83,30,71,8,50,2z" />
</svg>

我计划让这个图标独立，这样我只会动态传递百分比值。

不知何故，我能够完成动画，但不能保持svg的边框或轮廓。这是code。

#progressMove {
  transition: .3s y;
}
#progressMove:hover {
  y: 60%;
}

<svg id="kenseoProgress" width="79.36px" height="93.844px" viewBox="0 0 79.36 93.844">
  <defs>
    <mask id="bubbleKenseo">
      <path fill="red" stroke="black" d="M50,2C30-4,8,7,2,28c-6,20,5,42,26,48h0l-4,15l33-18c0-0,0-0,1-0l0-0l-0-0c8-4,15-12,17-22C83,30,71,8,50,2z" />
    </mask>
  </defs>
  <g x="0" y="0" width="79.36px" height="93.844px" mask="url(#bubbleKenseo)" height="100">
    <rect id="progressMove" x="0" y="0%" width="100%" height="100%" fill="blue" stroke="black" />
  </g>
</svg>

所以，我遇到的问题是：

无法维护SVG
的边框，无论我添加什么颜色都有某种我无法保持浏览器兼容性的不透明度: IE11+，chrome，safari和firefox

附言:我不想使用SMIL动画。

css

svg

css-shapes

svg-animate

首先，您要使用clip-path，或者将mask填充设置为白色以获得100%的不透明度：mask用作灰度alpha通道，红色填充颜色会导致不透明度发生变化。

至于笔划，您希望将其添加为不受剪切影响的单独元素。(您可以在defs和use__中重用该路径，我只是在这里复制粘贴了它)

#progressMove {
  transition: .3s y;
}
#progressMove:hover {
  y: 60%;
}

<svg id="kenseoProgress" width="79.36px" height="93.844px" viewBox="0 0 79.36 93.844">
  <defs>
    <clipPath id="bubbleKenseo">
      <path d="M50,2C30-4,8,7,2,28c-6,20,5,42,26,48h0l-4,15l33-18c0-0,0-0,1-0l0-0l-0-0c8-4,15-12,17-22C83,30,71,8,50,2z" />
    </clipPath>
  </defs>
  <path stroke="black" stroke-width="1" fill="transparent" d="M50,2C30-4,8,7,2,28c-6,20,5,42,26,48h0l-4,15l33-18c0-0,0-0,1-0l0-0l-0-0c8-4,15-12,17-22C83,30,71,8,50,2z" />
  <g x="0" y="0" width="79.36px" height="93.844px" clip-path="url(#bubbleKenseo)" height="100">
    <rect id="progressMove" x="0" y="0%" width="100%" height="100%" fill="blue" stroke="black" />
  </g>
</svg>

CHROME/SAFARI解决方案

使用CSS属性transform和counter-increment，您可以实现填充和数字递增。

代码片段

for (var i = 0; i < 100; i++) {
  setTimeout(function() {
    $(".progress-container p").append("<span>");
  }, i * 20);
}

pattern #progressMove {
  transform: translateY(100%);
  color: purple;
  animation: progressBar 2s steps(100, end) forwards;
}
@keyframes progressBar {
  to {
    transform: translateY(0);
  }
}
.progress-container {
  margin: 0;
  display: inline-block;
  position: relative;
  counter-reset: progress;
}
.progress-container figcaption {
  position: absolute;
  top: 40%;
  left: 50%;
  transform: translate(-40%, -50%);
}
.progress-container p {
  margin: 0;
  font-weight: bold;
}
.progress-container span {
  counter-increment: progress;
}
.progress-container p::after {
  content: counter(progress)"%";
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<figure class="progress-container">
  <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="79.36px" height="93.844px" viewBox="0 0 79.36 93.844">
    <pattern id="progress" x="0" y="0" width="79.36" height="93.844" patternUnits="userSpaceOnUse">
      <rect id="progressMove" x="0" y="0" width="100%" height="100%" stroke="none" fill="currentColor" />
    </pattern>
    <path fill="url(#progress)" stroke="#000" d="M50,2C30-4,8,7,2,28c-6,20,5,42,26,48h0l-4,15l33-18c0-0,0-0,1-0l0-0l-0-0c8-4,15-12,17-22C83,30,71,8,50,2z" />
  </svg>
  <figcaption>
    <p>

    </p>
  </figcaption>
</figure>

注意：

如果我能给出一个更好的解决方案来覆盖浏览器支持，我会更新。

编辑：

根据 answer，您还必须将背景的颜色更改为其父背景的颜色。

整个组件将是figure元素，遗憾的是，spritesheet中的符号仅用于提供路径和背景。

注意:此版本中删除了jQuery。

for (var i = 0; i < 100; i++) {
  setTimeout(function() {
    var progressCounter = document.querySelector(".progress__counter"),
      number = document.createElement("span");
    progressCounter.appendChild(number);
  }, i * 20);
}

#spritesheet {
  display: none;
}
.icon {
  display: inline-block;
  width: 1em;
  height: 1em;
}
.icon-bubble {
  font-size: 7em;
  color: white;
}
.progress-container {
  margin: 0;
  display: inline-block;
  position: relative;
  counter-reset: progress;
  overflow: hidden;
  line-height: 0;
}
.progress__inner {
  position: absolute;

具有模式和y转换的SVG：

svg:hover pattern #fillshape {
  y: 0%;
}
pattern #fillshape {
  transition: y 1s;
  y: 100%;
}

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="79.36px" height="93.844px" viewBox="0 0 79.36 93.844">
    <pattern id="pattern1"
           x="0" y="0" width="79.36" height="93.844"
           patternUnits="userSpaceOnUse" >

      <rect id="fillshape" x="0" y="0" width="100%" height="200%" stroke="none" fill="purple" />

  </pattern>
  <path fill="url(#pattern1)" stroke="black" d="M50,2C30-4,8,7,2,28c-6,20,5,42,26,48h0l-4,15l33-18c0-0,0-0,1-0l0-0l-0-0c8-4,15-12,17-22C83,30,71,8,50,2z" />
</svg>

现在，这在火狐或边缘中不起作用。它不会将x和y识别为CSS属性...

这是一个在svg形状后面使用div的解决方案。这种解决方案的缺点是svg形状得到了一个背景，例如。如果只想要形状，则必须将形状的背景色与页面的背景色相匹配。

svg {
  position: relative;
} 
.spesial {
  width: 90px;
  height: 0px;
  display: inline-block;
  background-color: purple;
  margin-left: -100px;
  transition: height 1s;
}
svg:hover + .spesial {
  height: 100px;
}

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="100" height="100" viewBox="0 0 75 90">
  <path stroke="black" fill="gray" d="M-10,-10 100,-10 100,100 -10,100 -10,-10  50,2C30-4,8,7,2,28c-6,20,5,42,26,48h0l-4,15l33-18c0-0,0-0,1-0l0-0l-0-0c8-4,15-12,17-22C83,30,71,8,50,2z" />

<div class="spesial">
