Angular-google-maps: 问题：MarkerManager.getNativeMarker()

我找到了解决方案

对于其他对该解决方案感兴趣的人，您必须创建一个新指令，并将其嵌套在 sebm-google-map 组件中。 将 MarkerManager 对象注入到此组件中，然后使用 Output 属性将其发出以将其传递给父组件。 例如：

<my-parent-component>
    <sebm-google-map>
        <get-map-objects (markerManager)="setMarkerManager($event)">
            <sebm-google-map-marker ... ></sebm-google-map-marker>
        </get-map-objects>
    </sebm-google-map>
</my-parent-component>

然后指令看起来像这样：

import { Directive, Output, EventEmitter, AfterViewInit, ContentChildren, QueryList } from '@angular/core';
import { GoogleMapsAPIWrapper, MarkerManager, SebmGoogleMapMarker } from 'angular2-google-maps/core';

@Directive({
  selector: 'get-map-objects',
})
export class GetMapObjectsDirective implements AfterViewInit {

  /**
   * Get native map object
   */
  private _map: any = null;
  @Output('map') mapChanged: EventEmitter<any> = new EventEmitter<any>();
  set map(val){
    this._map = val;
    this.mapChanged.emit(val);
  }
  get map(){
    return this._map;
  }

  /**
   * Get marker manager
   */
  private _markerManager: any = null;
  @Output('markerManager') markerManagerChanged: EventEmitter<MarkerManager> = new EventEmitter<MarkerManager>();
  set markerManager(val){
    this._markerManager = val;
    this.markerManagerChanged.emit(val);
  }
  get markerManager(){
    return this._markerManager;
  }

  /**
   * Get sebm markers
   */
  private _markers: any = null;
  @Output('markers') markersChanged: EventEmitter<SebmGoogleMapMarker[]> = new EventEmitter<SebmGoogleMapMarker[]>();
  set markers(val){
    this._markers = val;
    this.markersChanged.emit(val);
  }
  get markers(){
    return this._markers;
  }
  @ContentChildren(SebmGoogleMapMarker) markerChildren: QueryList<SebmGoogleMapMarker>;

  constructor(
    private googleMapsWrapper: GoogleMapsAPIWrapper,
    private googleMarkerManager: MarkerManager
  ) { }

  ngAfterViewInit() {
    // get native map
    this.googleMapsWrapper.getNativeMap().then(map => {
      this.map = map;
    }, error => {
      throw error;
    })

    // get marker manager
    this.markerManager = this.googleMarkerManager;

    // get markers
    this.markerChildren.changes.subscribe(markers => {
      this.markers = markers._results;
    })
  }
}

最后在您的父组件中，像这样使用标记管理器（和标记）：

setMarkerManager(markerManager: MarkerManager){
    this.markerManager = markerManager;
  }

  /**
   * Sets the markers, used by spidifier
   */
  setMarkers(markers: SebmGoogleMapMarker[]){
    this.markers = markers;
    for(let marker of markers){
      this.markerManager.getNativeMarker(marker).then(marker => {
        this.overlappingMarkerSpidifier.addMarker(marker);
      });
    }
  }

嗨@maxmumford
这正是我想要的，
太感谢了。

@maxmumford
我还有一个问题。
我想在标记悬停时手动添加信息窗口。
请为此发送一些示例吗？
