推荐答案

您可以使用地理编码查找国家的纬度/经度。

查看 sample from Google。

You could use Geocoding to lookup the Lat/Lng of the country.
Take a look at this sample from Google.

基本上你需要做像这样：

Basically you need to do something like this:

var country = "Germany";
var geocoder;

geocoder.geocode( {'address' : country}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
        map.setCenter(results[0].geometry.location);
    }
});

在初始化函数中，您需要设置geocoder对象的值，如下所示：

In your initialize function you'll need to set the value of the geocoder object, like this:

geocoder = new google.maps.Geocoder();

您需要制定适当的缩放级别，然后设置以地图为中心。

You'd need to workout what an appropriate zoom level would be, and then set that after you have centered the map.
