地理位置地图 JS.

在网址中：https://developers.google.com/maps/documentation/javascript/examples/map-geolocation您可以从函数句柄看到行图.setCenter（options.position）的NoGeolocation;

这是我设置中心地图的功能，纬度，lng和缩放级别，默认缩放级别= 7。

function SetCenterMap(lat, lng, zoom) {
    if (typeof (zoom) === 'undefined')
        zoom = 7;
    var center = new google.maps.LatLng(lat, lng);
    map.setZoom(zoom);
    map.setCenter(center);
}

试试这个，希望能帮到你:)

不起作用，地图不显示在客户端的当前位置！

这是我的js文件：
