这是一种从头开始重新启动 SVG 元素中的 <animate> 的方法吗?

Is here a way to restart from the beginning the <animate> in a SVG element?

只需要知道我们如何重新启动 <svg> 中的元素序列。谢谢。

        <animate attributeName="cy" dur="1s" repeatCount="indefinite" calcMode="spline" keySplines="0.45 0 0.9 0.55;0 0.45 0.55 0.9" keyTimes="0;0.5;1" values="23;77;23"></animate>

    <button onclick="RestartAnimate();">Restart Animate</button>
  </body>
  <script>
    function RestartAnimate() {
        // Do something...
    }
  </script>
</html>

<button onclick="RestartAnimate();"> 你必须去掉分号

分配动画标识符<animate id="an"

赋值begin="indefinite"

在下面的示例中,循环在按下按钮后重复三次 Restart Animate
