我一直在网上搜索解决方案，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。

我想要从 GPS 中提取的坐标用作我的谷歌地图的中心，所以当你在 fx 中时。在 Kongs nytorv 的哥本哈根，你会得到那个位置作为中心。

我的地图有一些选项： 

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
        }
    };

现在我有一个静态位置作为中心。
但我找不到从哪里获取信息

我一直在尝试解决这个问题，所以如果可能的话，我们都会找到解决问题的方法

这是来自谷歌文档的示例
