因此,我必须更新以前使用setTimeout而不是Callbacks编写的一些TypeScript代码,问题是我无法使其正常工作。
使用settimeouts的函数可以正常工作,因此没有理由与配置相关(库=场所等)。另外,我可以在日志中看到它确实在工作,但是我的地图是纯灰色的。
map_initialize(callback) {
navigator.geolocation.getCurrentPosition((position) => {
this.directionsService = new google.maps.DirectionsService();
this.localizacaoAtual = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var mapOptions = {
zoom: 8,
center: this.localizacaoAtual
}
if (this.origem == "atual") {
this.origem = this.localizacaoAtual;
}
callback({ mapOptions: mapOptions })
});
}
现在我要调用函数initialize
if (this.origem != null && this.destino != null) {
this.map_initialize((callback) => {
if (this.tipoMapa == "rota") {
this.map_calcRoute(callback);
} else if (this.tipoMapa == "radius") {
this.map_radius(callback);
}
});
}
如果要调用的第一个函数是路线图,它实际上是有效的。但是,如果我将“ this.tipoMapa”值更改为“ radius”,则不会加载。
map_radius(mapOptions: any) {
this.map = new google.maps.Map(document.getElementById('map'), mapOptions);
let service = new google.maps.places.PlacesService(this.map);
let start = this.origem;
let end = this.destino;
this.request = {
location: start,
radius: '1500',
name: ['something here']
}
service.nearbySearch(this.request, (results, status) => {
if (status === google.maps.places.PlacesServiceStatus.OK) {
var stepDisplay: any = new google.maps.InfoWindow();
for (var i = 0; i < results.length; i++) {
this.createMarker(results[i], stepDisplay);
}
}
this.entrada = { mensagem: status, origem: this.origem, destino: this.destino, instrucoes: this.instrucoes };
this.conversationService.sendMessage(this.entrada, this.context).subscribe(
data => {
this.conv_tratarRetorno(data);
}, error => { }
)
});
};
然后我有了我的createMarker函数。
createMarker(place, stepdisp) {
var marker = new google.maps.Marker({
map: this.map,
position: place.geometry.location
});
google.maps.event.addListener(marker, 'click', function () {
stepdisp.setContent(place.name);
stepdisp.open(this.map, marker);
});
}
因此,基本上,当我调用route函数时,它确实可以工作,但是如果我调用radius函数,它将返回灰色地图,但带有正确的日志。
谢谢!

解决了!我正在调用“ mapOptions”,却忘记了调用mapOptions.mapOptions。愚蠢的我...
