如何在SVG脈沖中制作圓/g/路徑元素

2022-01-19 10:04:48 前端設計

我有SVG以下地圖:

如何在SVG脈沖中制作圓/g/路徑元素

在地圖上,您會注意到橙色點。我想讓這些點像這樣跳動:

.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>

挑戰

  1. html標記不能在svg's 中使用,因此不能使用span上面的演示。
  2. 為了確保點的位置仍然正確,我添加了父g元素并將子transform屬性移動到父元素上。

這是原始(簡化)地圖:

如您所見,沒有任何反應。

然后我想也許效果需要發生在 apath而不是circle并嘗試過:

<path id="Ellipse_160-2" data-name="Ellipse 160" cx="9.5" cy="9.5" r="9.5" fill="#ff7c81"/>

代替:

<circle id="Ellipse_160-2" data-name="Ellipse 160" cx="9.5" cy="9.5" r="9.5" fill="#ff7c81"/>

但這一切只是隱藏了我的橙色circle

這里有可能產生脈沖效應嗎?

uj5u.com熱心網友回復:

在此示例中,我有兩個單獨的 SVG 元素(但它可能只有一個)。在第一個中,我定義了一個<symbol>帶有陰影和一個影片圓的 a。第一個 SVG 不占用空間(寬度和高度為 0)。

在第二個 SVG 中,您可以找到地圖。除了寬度,我沒有在這里改變任何東西。通過使用<use>,我現在可以在地圖上放置脈動圓圈。<use>好處是它有自己的viewBox 因此,符號中定義的大小將根據<use>元素使用的大小進行縮放。像這樣:

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

這將根據 viewBox 放置點(從左上角開始的 21,27)viewBox="0 0 37.013 41.348"

我已經制作的兩個點是兩種不同的大小——大小可以根據viewBox進行調整。這里棘手的部分是使用變換/翻譯將點放置在正確的位置。我無法看到您對<g>'s 所做的所有轉換/翻譯。所以,這里有一個實驗的問題。

要調整“脈動”,您可以在影片元素上使用屬性valuekeyTimesdur 。該值是屬性在持續時間 ( dur ) 范圍內將具有的值串列。它將有兩個或多個值。如果有兩個以上的值(例如下例中r的影片),則可以使用keyTimes屬性來設定中間配速。所以這里的值在 0 秒時為 0,在 1.5 秒后為 1 (0.75),在 2 秒后為 0 (1)。
