如何在vue js应用程序中使用bing maps api来显示地图?

注意

这是我的模板

<template>
   <div id="map"></div>
</template>

这是我的风格

<style lang="scss" scoped>
   #map {
      height: 300px;
      width: 500px;
   }
</style>

mounted() {
   let mapElement: HTMLElement = <HTMLElement>document.getElementById("map")
   var map = new Microsoft.Maps.Map(mapElement, {
     credentials: [API_KEY]
   });
}

我是如何从我的应用程序内包括这个脚本。经过一番研究,我发现并尝试了以下两种选择

<!-- index.html -->
...
<head>
   ...
   <script src="https://www.bing.com/api/maps/mapcontrol?key=[API_KEY]" async defer></script>
</head>

选项2:我在mounted方法中从我的组件在文档中注入programmatical脚本,如下所示

mounted() { 
   // Add programmaticaly the external Bing maps api script
   var scriptTag = document.createElement("script");
   scriptTag.src = "https://www.bing.com/api/maps/mapcontrol";
   scriptTag.id = "bingApiMaps";
   // Inject the dynamic script in the DOM
   document.head.appendChild(scriptTag);
   ...
}

在这两种情况下,我都有以下错误,我不明白为什么:

[Vue warn]: Error in mounted hook: "ReferenceError: Microsoft is not defined"

在经历了很多麻烦之后,我明白了。 Bing映射api是异步加载的。所以微软/Microsoft.Maps对象不直接可用。

我决定保留解决方案2来加载脚本(这样脚本就不会全局加载)。这是我最后的解决方案

<template>
  <div id="map" ref="map"></div>
</template>

<script lang="ts">
// Vue
import { Vue, Component } from "vue-property-decorator";

@Component
export default class AppMap extends Vue {
  mounted() {
    if (document.getElementById("scriptBingMaps")) {
      return; // already loaded
    }

    // Add a global function for the callback from Bing Maps api
    (<any>window).OnLoadBingMapsApi = () => this.InitMap();

    // Add programmaticaly the external Bing maps api script
    var scriptTag = document.createElement("script");
    scriptTag.src = "https://www.bing.com/api/maps/mapcontrol?callback=OnLoadBingMapsApi";
    scriptTag.id = "scriptBingMaps";
    // Inject the dynamic script in the DOM
    document.head.appendChild(scriptTag);
  }

  private InitMap(): void {
    let mapElement: HTMLElement = <HTMLElement>this.$refs.map;
    var map = new Microsoft.Maps.Map(mapElement, {
      credentials: [API_KEY]
    });
  }
}
</script>

<style lang="scss" scoped>
/* ==========================================================================
   Map
  ========================================================================== */
#map {
  height: 300px;
  width: 500px;
}
</style>

等等!:)

mounted: function() {

    return; // already loaded

  // Add a global function for the callback from Bing Maps api
  window.OnLoadBingMapsApi = () => this.InitMap();

  // Add programmaticaly the external Bing maps api script
  var scriptTag = document.createElement("script");
  scriptTag.src = "https://www.bing.com/api/maps/mapcontrol?callback=OnLoadBingMapsApi&key=[BING_API_KEY]";
  scriptTag.id = "scriptBingMaps";

  // Inject the dynamic script in the DOM
  document.head.appendChild(scriptTag);
},
methods: {
  InitMap: function() {
    var mapElement = this.$refs.myMap;

    this.map = new Microsoft.Maps.Map(mapElement, {
      mapTypeId: Microsoft.Maps.MapTypeId.aerial,
      zoom: 15,
      maxZoom: 21,
      //minZoom: 15,
      center: new Microsoft.Maps.Location(52.7759872, -1.5119702),
      maxNetworkLinkDepth: 3
    });
  }
