google-maps - 使用 Google map API 的可点击国家/地区

Question

我刚刚开始涉足 Google Maps API，但我已经陷入困境。我正在寻找一种重新创建 this 的方法谷歌地图的 map 类型。我需要删除所有标签，获得空白背景(我尝试使用 map 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国家/地区上方时点亮它们。

我在搜索中似乎错过了任何可以帮助我的教程，或者有人可以为我指出正确的方向吗？ :)

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"));
}

编辑这就是 map 的用途:我一生中旅行过一些地方，并希望能做更多的事情。自从我第一次长途旅行以来，我一直在写博客。我现在开发了一个新博客，我想让我去过的国家/地区可点击，并在点击后跟踪一个网址。理想的情况是，当我单击一个国家/地区时，它会将我带到一个页面，其中 map 中仅显示该特定国家/地区，并带有一些标记(要访问的地点)。单击这些标记后，它应该显示特定的帖子/一些信息。

这样的事情可以吗？复制并粘贴到 HTML 页面正文 ( JSFiddler here ) 中。
