ポリゴン (kml ファイル) を使用してマップ API v3 をセットアップしましたが、マーカーを同じマップに配置したいと考えています。マーカー (lat、lang) は、MySQL データベースから直接取得されます。

これが私のページのコードです：

このコードを関数 initialize() に追加しました

<?
$query = mysql_query("SELECT * FROM poi_example");
while ($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();

そして、上記のコードでわかる関数 addMarker を追加しました

コードのどこが間違っているか、何か不足していますか?

同じマップ上にポリゴンとマーカーを配置することは確かに可能です。

  1. 生成された HTML を質問への「回答」として追加しないでください。質問を編集して追加する必要があります。
  2. JavaScript エラーがあります
    • 関数 makeLink はありません
    • 境界は定義されていません。
  3. addMarkers 関数はアイコンを定義していません。

kmlは良いです：

これらのエラーを修正すると、うまくいきます
