use*_*108 8 angular-google-maps ngfor angular
我对角度很新,我认为这是一个基本问题.
我创建我的地图
<agm-map [latitude]="lat" [longitude]="lng">
<agm-marker [latitude]="location.lat" [longitude]="location.lng" *ngFor="let location of locations; let i=index">
<agm-snazzy-info-window [maxWidth]="200" [closeWhenOthersOpen]="true">
<ng-template>
<strong>{{location.title}}</strong>
<p>adresse</p>
</ng-template>
</agm-snazzy-info-window>
</agm-marker>
</agm-map>

当我手动设置标记时,一切正常,但是当我*ngFor用来遍历我的列表时,会创建标记的html,但显然在地图的脚本查找标记之后,所以没有标记被渲染(地图本身就是) .
从我的控制器:
export class LocationMapComponent implements OnInit {
lat: number = 51.678418;
lng: number = 7.809007;
locations: Location[];
async ngOnInit() {
}
public async getLocations() {
this.locations = await this._locationService.getLocations();
}
constructor(private _locationService:LocationService, private _coreCOMService: CoreCOMService, private _coreLanguageService: CoreLanguageService, private _coreLogService: CoreLogService, private _componentFactoryResolver: ComponentFactoryResolver, private _coreSystemService: CoreSystemService) {
this.getLocations();
}

}
这些位置是从一个从远程数据库中获取它们的服务加载的.我确实认为问题是在执行ngFor循环之前渲染了地图,我不确定如何确保首先执行循环或者如何告诉地图仅在循环之后(重新)渲染标记已经完成了.
如上所述,这可能是非常基本的,但我现在感到茫然,谢谢.
