点击时的心脏动画答案

【问题标题】：Heart Animation on click点击时的心脏动画
【发布时间】：2020-06-23 23:58:45
【问题描述】：

所以我想创建一个动画，在其中单击心脏，心脏周围有一个圆圈，该圆圈按比例放大然后逐渐消失。我试图给 SVG 一个边框，但什么也没显示？老实说，我不确定我在这里做错了什么。任何帮助将不胜感激。我希望它类似于 Twitter 心脏，但当你点击它时心脏周围没有圆点。这是我的代码笔的链接https://codepen.io/Brushel/pen/MEEYgQ

(function() {
  var animatedHeart, heartanimation, heartanimationthree;

  animatedHeart = document.getElementById('heart1');

  heartanimation = document.getElementById('heart2');

  heartanimationthree = document.getElementById('heart3');

  animatedHeart.addEventListener('click', function() {
    return animatedHeart.classList.toggle('fill');
  });

  heartanimation.addEventListener('click', function() {
    return heartanimation.classList.toggle('fillup');
  });

  heartanimationthree.addEventListener('click', function() {
    return heartanimationthree.classList.toggle('heartscale');
  });

}).call(this);

【问题讨论】：

所以你想在一颗心周围加上一个边框？
是的，但我不希望边框触动人心。我知道我可以使用 stoke: {} 但我想让边框根本不触及心脏。如果这有任何意义@tomsmithweb

【解决方案1】：

最后一个看起来很接近！我认为在 css 中有一种更简单（更简单）的方法。

Nicolas Escoffer 在这里有一篇很棒的文章：

代码笔： https://codepen.io/OxyDesign/pen/avXVbo

否则我会建议使用您创建的圆形 div 的边框创建一个关键帧动画。确保将圆形 div 设置在 heart .svg 之外，这样它就不会包裹元素：

我根据你原来的 codepen 在下面为你做了一个例子：

#HTML:

<body>
  <div class="container">
    <div class="col-12">
      <h2>&nbsp;</h2>
      <br>
      <div id="circle" class="circle"></div>
       <svg class="mo-icon__svg" x="0px" y="0px"
     viewBox="0 0 200 200" style="enable-background:new 0 0 200 200;" xml:space="preserve" id="heart4">
<g id="icon_x5F_wishlist">
    <g transform="translate(0,-952.36218)">
        <path class="st0" id="st0" d="M15.33293,980.7616c-19.11968,19.8092-19.10147,51.68518,0,71.51379l84.61456,87.86926
