Angular 9和Google Map Marker单击事件无法正常工作

问题描述

下面是我的代码，用于初始化地图并添加聚类和标记。一切工作正常，但是标记单击的行为很奇怪，就像事件立即被触发并点击API一样，但是全局变量在几秒钟后，几分钟后就会更新。

  renderMap() {

    window['initMap'] = () => {
      this.loadMap();
    };
    if (!window.document.getElementById('google-map-script')) {
      const s = window.document.createElement('script');
      s.id = 'google-map-script';
      s.type = 'text/javascript';
      s.src = 'https://maps.googleapis.com/maps/api/js?key=' + environment.GOOGLE_MAP_API_KEY + '&callback=initMap';

      window.document.body.appendChild(s);
    } else {
      this.loadMap();
    }
  }

  loadMap() {
    const map = new window['google'].maps.Map(this.mapElement.nativeElement,{
      center: {lat: this.center.lat,lng: this.center.lng},zoom: this.zoom
    });
    const markers = this.markers.map((location,i) => {
      const marker = new google.maps.Marker({
        position: {lat: location.lat,lng: location.lng},label: location.label,icon: 'assets/img/marker_.png',title: location.title,clickable: true
      });

      marker.addListener('click',() => {
        const m = location;
        this.customer = m;
        this.showLocation = true;
        this.loading = true;
        this.center = {
          lat: m.lat,lng: m.lng
        };
        this.companyService.company(m.company_id).subscribe((company: any) => {
          this.company = company;
          this.loading = false;
        },error => {
          this.loading = false;
          console.log(error);
        });
      });
      return marker;
    });

    const markerCluster = new MarkerClusterer(map,markers,{imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'});

  }

  ngOnInt(){
    this.renderMao();
  }

解决方法

您可能需要在NgZone中运行click回调

constructor(private zone: NgZone)


marker.addListener('click',() => {
    this.zone.run(() => { 
     ...
});
