現在、私は現在、ユーザーが Google フュージョン テーブル オーバーレイを使用して別のマップ ビューに変更できる JavaScript メニューを持つマップを作成しています。私の最初のドロップダウン メニューは魅力的に機能します。ただし、2 番目のドロップダウン メニューは他のドロップダウン メニューでは機能しません。二人で頑張ってほしいです。たとえば、誰かが「動物」と「機会」を選択すると、「動物」と「機会」のセル データを含む場所が表示されます。

これは私の Google マップの HTML ページです。

ここに解決策があります-Chromeでテストされました;）-新しいボタン、refreshFusionメソッド、および2つの選択要素のid属性に注意してください。
