如何在SVG脉冲中制作圆/g/路径元素

【问题标题】：How to make circle / g / path element in SVG pulse如何在SVG脉冲中制作圆/g/路径元素
【发布时间】：2022-01-19 05:18:23
【问题描述】：

我有以下地图的SVG：

在地图上，您会注意到橙色圆点。我想让这些点像这样跳动：

.pulse {
  margin:100px;
  display: block;
  width: 22px;
  height: 22px;
  border-radius: 50%;
  background: #cca92c;
  box-shadow: 0 0 0 rgba(204,169,44, 0.4);
  animation: pulse 2s infinite;
}

@-webkit-keyframes pulse {
  0% {
    -webkit-box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
  }
  70% {
      -webkit-box-shadow: 0 0 0 10px rgba(204,169,44, 0);
  }
  100% {
      -webkit-box-shadow: 0 0 0 0 rgba(204,169,44, 0);
  }
}
@keyframes pulse {
  0% {
    -moz-box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
    box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
  }
  70% {
      -moz-box-shadow: 0 0 0 10px rgba(204,169,44, 0);
      box-shadow: 0 0 0 10px rgba(204,169,44, 0);
  }
  100% {
      -moz-box-shadow: 0 0 0 0 rgba(204,169,44, 0);
      box-shadow: 0 0 0 0 rgba(204,169,44, 0);
  }
}
<span class="pulse"></span>

挑战：

  1. html 标记不能在 svg 中使用，因此不能使用 span 作为上面的演示。
  2. 为了确保点的位置仍然正确，我添加了父 g 元素并将子 transform 属性移到父元素上。

这是原始（简化）地图：

</div>

如您所见，没有任何反应。

然后我想也许效果需要发生在path而不是circle上并尝试了：

&lt;path class="map--pulse" id="Ellipse_160-2" data-name="Ellipse 160" cx="9.5" cy="9.5" r="9.5" fill="#ff7c81"/&gt;

代替：

&lt;circle class="map--pulse" id="Ellipse_160-2" data-name="Ellipse 160" cx="9.5" cy="9.5" r="9.5" fill="#ff7c81"/&gt;

但这一切只是隐藏了我的橙色circle。

这里可以产生脉冲效应吗？

    选项使用*.png 格式的地图

    使用&lt;image&gt;标签添加地图图像

    这将允许您在地图顶部放置标记并将它们链接到地图上的某些位置。无论缩放和使用任何小工具，地图上标记和地点的相对位置都将保持不变。

    【讨论】：

      【解决方案2】：

      在这个例子中，我有两个独立的 SVG 元素（但它可能只有一个）。在第一个中，我定义了一个带有阴影和动画圆的&lt;symbol&gt;。第一个 SVG 不占用空间（宽高均为 0）。

      在第二个 SVG 中，您可以找到地图。除了宽度，我没有在这里改变任何东西。通过使用&lt;use&gt;，我现在可以在地图上放置脉动圆圈。 &lt;use&gt; 的好处是它有自己的 viewBox。因此，符号中定义的大小将根据&lt;use&gt; 元素使用的大小进行缩放。像这样：

      <use href="#pulse" width="4" height="4" x="21" y="27"/>

      这将根据 viewBox viewBox="0 0 37.013 41.348" 放置点（从左上角开始的 21,27）。

      我已经制作的两个点是两种不同的大小——大小可以根据viewBox进行调整。这里棘手的部分是使用变换/翻译将点放置在正确的位置。我无法看到您对&lt;g&gt; 所做的所有转换/翻译。所以，这里有一个实验的问题。

      更新

      要调整“脉动”，您可以使用动画元素上的属性 value、keyTimes 和 dur。该值是属性将在持续时间 (dur) 范围内具有的值的列表。它将有两个或多个值。如果有两个以上的值（如下例中 r 的动画），可以使用 keyTimes 属性来设置中间步速。所以这里的值在 0 秒时为 0，在 1.5 秒后为 1 (0.75)，在 2 秒后为 0 (1)。

      <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 10 10" width="300">
  <symbol id="pulse" viewBox="0 0 4 4">

    <circle  cx="2" cy="2" r="1" fill="orange">
      <animate attributeName="r" values="1;2;1" keyTimes="0; 0.75; 1" dur="2s" repeatCount="indefinite" />
      <animate attributeName="opacity" values="1;0" keyTimes="0;1" dur="2s" repeatCount="indefinite" />
    </circle>

      【讨论】：

      • 嗨，这是一种非常不同的方法，看起来很有趣！您的&lt;use&gt; 元素中的一个问题是，您如何确定transform value？例如，在你的第一个&lt;use&gt; 中，你有transform="translate(18 5)"，在我原来的演示中，我没有transform="translate(18 5)" 的任何东西？
      • @Freddy 我更新了我的答案。关于转换/翻译的事情尚不清楚。我稍微调整了符号的大小，然后改用 &lt;use&gt; 上的 x 和 y 属性。这使得点的放置方式更加清晰（我希望......）。
      • 啊，我明白了，设法在我更大的地图中实现use :) 另一个问题，在您的演示中，点跳动然后重置（它们隐藏了一微秒，然后重新出现），是那是一种让它更流畅，让它不隐藏的方法？
      • @Freddy 我做了第二个例子，只是用符号和一个小解释。可能有不同的方法来获得更流畅的动画。自己试试吧。
