我已经用我的多边形(kml 文件)设置了地图 api v3,但现在我想将标记放在同一张地图上。标记(lat、lang)直接来自 MySQL 数据库。
这是我的页面的代码:

我将此代码添加到函数 initialize()
<?
$query = mysql_query("SELECT * FROM poi_example");
while ($row = mysql_fetch_array($query)){
$name=$row['name'];
$lat=$row['lat'];
$lon=$row['lon'];
$desc=$row['desc'];
echo ("addMarker($lat, $lon,'<b>$name</b><br/>$desc');\n");
}
?>
center = bounds.getCenter();
并添加了您可以在上面的代码中看到的函数 addMarker
代码中的错误或缺少什么?
