是否有相当于 CSS 的动画填充模式的 SVG：转发？答案

【问题标题】：Is there an SVG equivalent of CSS' animation-fill-mode: forwards?是否有相当于 CSS 的动画填充模式的 SVG：转发？

【问题描述】：

我想为形状设置动画并防止它们在起点处重置。

我想使用 animation-fill-mode:forwards;，但我不确定它是否适用以及在我的标签中放置它的位置。

Here 可以看到我的圆圈被重新定位在左上角，而我想让它停留在它的运动路径结束的地方，在六边形的顶点。

【解决方案1】：

使用fill="freeze" 作为animateMotion 的属性，如下所示：

<svg width="400" height="400" viewBox="0 0 200 200"
        xmlns="http://www.w3.org/2000/svg" version="1.1"
        xmlns:xlink="http://www.w3.org/1999/xlink" style="background:aquamarine">



        <circle cx="50%" cy="50%" r="1" fill="firebrick"  />

        <path id="theMotionPath" d="m 100,100 -0.000003,-52.916668 45.82718,26.458333 0,52.916665" stroke-width="5px" stroke="antiquewhite" fill="none" stroke-linecap="round" stroke-linejoin="round" />

        <path id="theMotionPath2" d="m 100,100 -0.000003,-52.916668 45.82718,26.458333 0,52.916665" stroke-width="5px" stroke="aqua" fill="none" style="transform-origin:50%;transform: rotate(120deg);" stroke-linecap="round" stroke-linejoin="round" />

        <path id="theMotionPath3" d="m 100,100 -0.000003,-52.916668 45.82718,26.458333 0,52.916665" stroke-width="5px" stroke="azure" fill="none" style="transform-origin:50%;transform: rotate(240deg);" stroke-linecap="round" stroke-linejoin="round" />

        <circle cx="0" cy="0" r="5" fill="#333333">
          <animateMotion dur="0.45s" repeatCount="once" fill="freeze">
            <mpath xlink:href="#theMotionPath3"/>
          </animateMotion>
        </circle>

        <g style="transform-origin:50%;transform: rotate(120deg);">
          <circle cx="0" cy="0" r="5" fill="#333333">
            <animateMotion dur="0.45s" repeatCount="once" fill="freeze">
              <mpath xlink:href="#theMotionPath3"/>
            </animateMotion>
          </circle>
        </g>

        <g style="transform-origin:50%;transform: rotate(240deg);">
          <circle cx="0" cy="0" r="5" fill="#333333">
            <animateMotion dur="0.45s" repeatCount="once" fill="freeze">
              <mpath xlink:href="#theMotionPath3"/>
            </animateMotion>
          </circle>
