我一直在整个网络上寻找解决方案，但我仍然无法找到任何解决方案，我一直在谷歌自己的自由中找到这个问题。
我想要从 GPS 中提取坐标作为我的谷歌地图的中心，这样当你在 fx.在哥本哈根 Kongs nytorv，您将获得中锋的位置。
我的 map 有一些选项:
var myOptions = {
center: new google.maps.LatLng(55.674, 12.403),
zoom: 10,
disableDefaultUI: true,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: false,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR,
position: google.maps.ControlPosition.BOTTOM_CENTER
},
panControl: true,
panControlOptions: {
position: google.maps.ControlPosition.TOP_RIGHT
},
zoomControl: true,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.LARGE,
position: google.maps.ControlPosition.LEFT_CENTER
},
scaleControl: false,
scaleControlOptions: {
position: google.maps.ControlPosition.BOTTOM_CENTER
},
streetViewControl: true,
streetViewControlOptions: {
position: google.maps.ControlPosition.BOTTOM_CENTER
}
};
现在我有一个作为中心的静态位置。
但我找不到从哪里获取信息
我继续尝试解决这个问题，以便我们都能找到可能的解决方案
