Question

我一直在网上寻找解决方案，我仍然无法找到任何解决方案，iv在googles自己的libery中找到了这个。

我希望提取坐标，从GPS用作我的谷歌地图的中心所以当你在fx。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无法找到从哪里提取信息

我一直试图解决这个问题，所以我们都可以解决问题，如果可能的话

以下是google docs的示例

这是代码，如果此链接断开：
