私の目標は、マーカーの 4 つの異なるグループを作成することです (各グループで 3 つの異なる色を使用できます)。マップの上部にあるチェックボックスに基づいてオン/オフできるようにする必要があります: グループ 1、2、3、4 と、これらのグループを色でフィルタリングする方法 (例: グループ 1、グループ 2、グループ 3、グループ 4 & 赤、黄、緑)。私はもともとこれをプルダウンリスト用に設定していました。現在、これらのクリックイベントに応答するチェックボックスを取得する際に問題が発生しています。私は経験豊富な開発者ではないので、これを正しく説明していない場合は事前にお詫び申し上げます。アドバイスをいただければ幸いです。以下のコード:
