【问题描述】：
由于需要葡萄牙地图，用户可以点击选择地区，我关注了this example 和this one。问题是我使用 KML 文件将每个区域绘制为多边形，而不是使用 KML 绘制所有区域多边形。
已经在这里搜索了很多问题，还尝试更改 useTheData() 回调函数以包含一个额外的 for 循环，如下所示，但没有成功......
function useTheData(doc) {
var sidebarHtml = '<table><tr><td><a href="javascript:showAll();">Show All</a></td></tr>';
for (var j = 0; j < doc.length ; j++) {
...
}
sidebarHtml += "</table>";
document.getElementById("map_barralateral").innerHTML = sidebarHtml;
};
在地图上悬停区域可以正常工作，但是当单击侧边栏上的突出显示链接时，它默认突出显示使用列表的最后一个 KML 文件创建的多边形...
有没有办法解决这个问题？
