谷歌地图API当前位置不断更新

Question

我正在将Google Maps API集成到应用程序中，而Google Maps API需要我当前的位置。

我可以按预期提供我的当前位置，但如何用我的实时位置动态更新它？

这是我的代码：

@push('scripts')
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=&libraries=places&callback=initMap" async defer></script>
<script>
// Loading in google maps
function initMap() {
let spain = {lat: 40.4637, lng: -3.7492};
map = new google.maps.Map(document.getElementById('map'), {
zoom: 16,
center: spain
});
let infoWindow = new google.maps.InfoWindow;
let markers = {!! $markers->toJson() !!};
let hotspotLoc = {
lat: Object.values(markers)[0].lat,
lng: Object.values(markers)[0].lng
};
map.setCenter(hotspotLoc);
// Loading in Markers from the database
$.each(markers, function (key, marker) {
let id = marker.id;
let name = marker.name;
let addres = marker.addres;
let lesson = 0;
if (marker.lesson && marker.lesson.length > 0) {
lesson = marker.lesson[0].id;
}
let lat = marker.lat;
let lng = marker.lng;
let type = marker.type;
let markerLatlng = new google.maps.LatLng(parseFloat(lat), parseFloat(lng));
let mark = new google.maps.Marker({
position: markerLatlng,
map: map,
lesson: lesson,
});

new google.maps.event.trigger(markers, 'click');
mark.setMap(map);
});
}
function handleLocation(browserGeoLocation, infoWindow, pos) {
infoWindow.setPosition(pos);
infoWindow.setContent(browserHasGeoLocation ? 'Error: The Geolocation service has failed!' :
'Error: Your browser doesn/t support Geolocations!');
infoWindow.open(map);
}
function disableLesson() {
const listOfLesson = $(".lockLesson:not(.disabled)").slice(1);
listOfLesson.each(function() {
$(this).addClass('disabled');
//$(this).find('.d-flex .btn-dark').append('<div class="fas fa-lock fa-lg mx-2"></div>');
$(this).find('.d-flex .d-none').removeClass("d-none");
});
}
$(() => {
disableLesson();
});
</script>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAtqWsq5Ai3GYv6dSa6311tZiYKlbYT4mw&callback=initMap">
</script>

希望有人知道如何使其可更新，以便我可以继续我的项目。

你必须使用 setInterval javascript 函数

// call funtion to get and set location
setInterval(function () {
// Call function get and set location
}, 5000);
