//this code to get current location
if(!!navigator.geolocation) {
var map;
var mapOptions = {
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'), mapOptions);
navigator.geolocation.getCurrentPosition(function(position) {
var geolocate = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: geolocate,
content:"<b>Posisi Kamu Sekarang</b>"
});
var title = "<b>Posisi Kamu Sekarang</b>";
var tanda = new google.maps.Marker({
map: map,
position: geolocate
});
google.maps.event.addListener(tanda, 'click', function() {
infoWindow.setContent(title);
infoWindow.open(map, tanda);
});
markers.push(tanda);
map.setCenter(geolocate);
});
<script async defer

</script>
//此代码用于获取当前位置
如果(!!navigator.geolocation){
var映射;
变量映射选项={
缩放:15,
mapTypeId:google.maps.mapTypeId.ROADMAP
};
map=new google.maps.map(document.getElementById('map'),mapOptions);
navigator.geolocation.getCurrentPosition(函数(位置){
var geologite=new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
var infowindow=new google.maps.infowindow({
地图:地图,
位置:地理定位,
内容:“Possi Kamu Sekarang”
});
var title=“Posisi Kamu Sekarang”;
var tanda=新的google.maps.Marker({
地图:地图,
位置:地理定位
});
google.maps.event.addListener(tanda,'click',function(){
infoWindow.setContent(标题);
打开(地图,坦达);
});
推(坦达);
地图设置中心(地理定位);
});
当我使用公共网络加载此代码时。它成功加载,标记和地图显示我在“kudus”的当前位置。但当我在家尝试时,使用我的Redmi 4x的热点连接。我的当前位置生成“三宝垄”。
如何使当前位置精确到我现在的位置?我希望这对您有用 请提供API密钥并运行此代码
