使用Google Maps API的可点击国家/地区

Question

我刚刚开始涉足谷歌地图API,但我已经陷入困境.我正在寻找一种方法来使用谷歌地图重新创建这种类型的地图.我需要删除所有标签,获得一个空白背景(我尝试使用地图样式,但这对我不起作用,下面的代码示例)并在我将鼠标悬停在它们上时点亮这些国家/地区.

在我的搜索中是否有任何我可能错过的教程可以帮助我,或者任何人都可以指出我正确的方向？:)

var _mapstyle = [
  {
    featureType: "all",
    elementType: "labels",
    stylers: [
      { visibility: "off" }
    ]
  }
];

function create_map()
{
    _map = new google.maps.Map(document.getElementById("eyewebz-map"), 
    {
        zoom: 2,
        center: new google.maps.LatLng(20, 0), 
        navigationControl: true,
        navigationControlOptions: {
            style: google.maps.NavigationControlStyle.DEFAULT
        },
        mapTypeControl: true,
        mapTypeControlOptions: {
            style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
        },
        scaleControl: true, 
        mapTypeIds: ['_mapstyle']
    });

    _display.setMap(_map);
    _display.setPanel(document.getElementById("NavigationText"));
}

编辑 这是地图将用于:我已经走了一段时间,并期望做更多的事情.自从我第一次出访以来,我一直在博客上.我现在已经开发了一个新的博客,我想让我可以点击的国家/地区点击后点击一个网址.理想的情况是,当我点击某个国家/地区时,会将我带到一个页面,其中只有该特定国家/地区会显示在带有某些标记的地图中(访问的地点).单击这些标记后,它应显示特定的帖子/某些信息.

这样的东西还可以吗？复制并粘贴到HTML页面主体(这里是JSFiddler).

这是此Fusion Tables Layer示例:Mouseover Map样式的修改版本 .

您还应该看看Styled Maps.
