Google 高级标记动画不起作用

问题描述 投票：0回答：1

我正在尝试将我的自定义地图标记迁移到新的高级标记库，似乎动画选项不再可用，它给了我这个错误：

AdvancedMarkerElement 的未知属性“动画”

我检查了文档，动画选项仍然存在，但没有提到如何迁移动画选项。

谷歌标记文档

newMarker = new google.maps.marker.AdvancedMarkerElement({
    position: markerOpposto,
    map: map,
    content: imageIcon,
    title: "New position",
    animation: google.maps.Animation.BOUNCE 
})
javascript google-maps google-api migration google-maps-markers

使用 CSS 动画进行高级标记

我们需要了解的关于高级标记的第一件事是，与传统标记不同，它不再是MVC对象。旧标记上存在的 

Animation contants
（
BOUNCE
和 
DROP
）不再可用。

这是因为，根据文档，高级标记类现在扩展了

HTMLElement
。这意味着要为高级标记设置动画，您现在应该使用 CSS 动画，如此处的高级标记示例中所示：https://developers.google.com/maps/documentation/javascript/examples/advanced -标记动画

话虽如此，要重现有点类似的弹跳动画，您首先需要使用关键帧和变换在 CSS 中定义一个 

.bounce
（您可以随意命名）类：

.bounce {
    animation: bounce 2s infinite;
    -webkit-animation: bounce 2s infinite;
    -moz-animation: bounce 2s infinite;
    -o-animation: bounce 2s infinite;
}
 
@-webkit-keyframes bounce {
    0%, 20%, 50%, 80%, 100% {-webkit-transform: translateY(0);} 
    40% {-webkit-transform: translateY(-30px);}
    60% {-webkit-transform: translateY(-15px);}
}
 
@-moz-keyframes bounce {
    0%, 20%, 50%, 80%, 100% {-moz-transform: translateY(0);}
    40% {-moz-transform: translateY(-30px);}
    60% {-moz-transform: translateY(-15px);}
}
 
@-o-keyframes bounce {
    0%, 20%, 50%, 80%, 100% {-o-transform: translateY(0);}
    40% {-o-transform: translateY(-30px);}
    60% {-o-transform: translateY(-15px);}
}
@keyframes bounce {
    0%, 20%, 50%, 80%, 100% {transform: translateY(0);}
    40% {transform: translateY(-30px);}
    60% {transform: translateY(-15px);}
}

然后在地图初始化函数中，您可以使用以下代码将类 

.bounce
添加到标记元素：

marker.content.classList.add("bounce")

然后动画应该可以工作了。

这里有一个概念证明片段供您检查：

  // Request needed libraries.

  // initialize the map
  const map = new Map(document.getElementById("map"), {
    center: { lat: 37.4239163, lng: -122.0947209 },
    zoom: 14,

  const marker = new AdvancedMarkerElement({

  // add the class "bounce" for your css configuration to apply
