示例1: getLocation
getLocation(){
this.geolocation.getCurrentPosition().then(pos =>{
this.latitude = pos.coords.latitude;
this.longitude = pos.coords.longitude;
console.log('lat: ' + pos.coords.latitude + ', lon: ' + pos.coords.longitude);
});
let watch = this.geolocation.watchPosition().subscribe(pos =>{
console.log('lat: ' + pos.coords.latitude + ', lon: ' + pos.coords.longitude);
});
watch.unsubscribe();
}示例2: ionViewDidLoad
ionViewDidLoad() {
console.log('ionViewDidLoad GpsLocationPage');
this.geolocation.getCurrentPosition().then((resp) => {
// resp.coords.latitude
// resp.coords.longitude
console.log("LAT :",resp.coords.latitude);
console.log("LOG :",resp.coords.longitude);
}).catch((error) => {
console.log('Error getting location', error);
});
let watch = this.geolocation.watchPosition();
watch.subscribe((data) => {
// data can be a set of coordinates, or an error (if an error occurred).
// data.coords.latitude
// data.coords.longitude
console.log("Data LAT :",data.coords.latitude);
console.log("Data LOG :",data.coords.longitude);
});
}示例3: mapSetUp
/*
here is where the map object is initialized
it is centered and zoomed in to an appropriate level and
contained in the appropriate bounds
and populated with all the markers
*/

//here is where the phone's geolocation is first defined
//there is also an error function just incase the setup was unsuccessful
//var userLoc = undefined;

});
//here is where the map is initialized, if the user's geolocation is defined and within mapBounds,
//then it is the map's center, otherwise the default center is used

zoom: 17,
mapTypeId: google.maps.MapTypeId.ROADMAP
}

//marker accordingly

.filter((p) => p.coords !== undefined)
.subscribe(position => {
let newUserLoc = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
