marker-animate-unobtrusive 初始化报错

import SlidingMarker from 'marker-animate-unobtrusive'

初始化:

SlidingMarker.initializeGlobally()

报错:

解决方法

因为SlidingMarkerextends google.maps.Marker类需要首先加载GoogleMaps JavaScript API库，一个选择是通过index.html文件添加引用：

<script src="https://maps.googleapis.com/maps/api/js?key=--KEY-GOES-HERE--"></script>

另一种选择是利用异步 JavaScript加载程序，例如scriptjs。加载GoogleMaps JavaScript API和marker-animate-unobtrusive模块的示例如下所示：

created: function(){
  get("https://maps.googleapis.com/maps/api/js?key=", () => {

    const SlidingMarker = require('marker-animate-unobtrusive')
    SlidingMarker.initializeGlobally()

    const map = new google.maps.Map(document.getElementById('map'), this.mapOptions);

    const marker = new SlidingMarker({
        position: this.mapOptions.center,
        map: map,
        title: 'Im sliding marker'
    });
 });

}

这是一个演示供您参考

更新资料

与vue-google-maps库 marker-animate-unobtrusive插件可以这样集成：

<template>
  <div>
    <GmapMap :center="center" :zoom="zoom" ref="mapRef"></GmapMap>
  </div>
</template>

<script>

/* global google */

export default {
  data() {
    return {
      zoom: 12,
      center: { lat: 51.5287718, lng: -0.2416804 },
    };
  },
  mounted: function() {
     this.$refs.mapRef.$mapPromise.then(() => {
        this.initSlidingMarker(this.$refs.mapRef.$mapObject)
    })
  },
  methods: {
    initSlidingMarker(map){
       const SlidingMarker = require('marker-animate-unobtrusive')
       SlidingMarker.initializeGlobally()


       const marker = new SlidingMarker({
            position: map.getCenter(),
            map: map,
            title: 'Im sliding marker'
       });

       google.maps.event.addListener(map, 'click', (event) => {
          marker.setDuration(1000);
          marker.setEasing('linear');
          marker.setPosition(event.latLng);
       });
    }
  }
}
</script>

.vue-map-container {
