SVG进度条

我有一个要求,我需要动态加载js文件并显示通过SVG图标加载文件的进度。 SVG图标将作为进度条,从底部到顶部线性填充颜色。

这是codepen

<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>

我打算让这个图标独立,这样我才会动态传递百分比值。

我能以某种方式完成动画,但无法保持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
  • 无论我添加的颜色是什么,都有某种不透明度,我无法删除。
  • 修改:浏览器兼容性:IE11 +,Chrome,safari和firefox

PS:我不想使用SMIL动画。

CHROME / SAFARI SOLUTION

使用CSS属性transformcounter-increment可以实现填充和数字增量。

注意:

如果我能提供更好的解决方案来支持浏览器支持,将会更新。

编辑:

根据Persijn回答,您还必须将背景颜色更改为其父颜色。

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

  

注意:此版本中删除了jQuery。

带有模式和y过渡的SVG:

&#13;
&#13;
svg:hover pattern #fillshape {
  y: 0%;
}
pattern #fillshape {
  transition: y 1s;
  y: 100%;
}
&#13;
<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>
&#13;
&#13;
&#13;

现在这不适用于 Firefox或Edge 。它不能将x和y识别为CSS属性......

这是一个使用svg形状后面的div的解决方案。 这个解决方案的缺点是svg形状有背景,例如。如果你只想要形状,你必须将形状的背景颜色与页面背景颜色相匹配。

&#13;
&#13;
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;
}
&#13;
<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">

首先,您要使用clip-path,或将mask填充设置为白色以获得100%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的变化。

对于笔划,您希望将其添加为不受剪裁影响的单独元素。 (您可以重复使用defsuse的路径,我只需将其复制粘贴在此处)

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

/*prDom.setAttributeNS(null, 'y', '0');*/

var cTimer = setInterval(function() {

  if (prValue >= 100) {

#progressMove {
  transition: transform 0.20s linear;
}
#progressMove.prHover {
  transform: translateY(40%) !important;
