私はGoogleマップにPamela Foxの「スマート情報ウィンドウ」コードを実装しようとしていますが、これを動作させることはできません。マーカーが正しく配置された状態で地図が表示されます。しかし、私がマーカーをクリックしても何も起きませんが、エラーメッセージが表示されず、これで少し失われることを認めなければなりません。スマート情報ウィンドウとGoogleマップマーカー
どこが間違っていますか？

こんにちは、私の投稿に返信する時間を取るための多くのおかげでは、当然のです。私はあなたが示唆したようにコーディングを変更しましたが、マーカーをクリックすると次のエラーが表示されます。メッセージ：タイプの不一致。行：151文字：1コード：0 URI：http：//websitename/js/SmartInfoWindow.js 私はJavascriptを使いました。＆そのHTMLファイルとの間にスペルの違いはありません。私はまた、ファイルのパスがcoorectされていることを確認しましたが、何もそこに紛れているようです。あなたは問題が何であるかについてあなたに何かアイデアを教えてください。多くのありがとうと親切に感謝します。クリス – IRHM
私はそうは確信していませんが、このスマート情報ウィンドウのコンストラクタでは、私はウィンドウの内容（this.content_ = opts.content;）への割り当てを参照してください - これは、あなたの3番目の引数あなたが入力したようにhtmlではないcontentという名前のフィールドから呼び出す）。私の推測は、変更することです： var infobox = new SmartInfoWindow（{position：point、map：map、html：html}）; into： var infobox = new SmartInfoWindow（{position：point、map：map、content：html}）; 希望に役立ちます。 – slawekwin
こんにちは、私にこれを手伝ってくれてありがとう。私はhttp://code.google.com/p/gmaps-samples-v3/source/browse/trunk/smartinfowindow/smartinfowindow.html?r=63でGoogleサイトのコーディング＆デモに戻りましたデモを見ると、あなたが言ったようにコンテンツは、私のhtml同義語だと言われています。私はあなたが示唆したようにコードを変更しました＆私はまたデモに一致するように私のコードで 'var html'を変更しました。コードはある程度機能しますが、フレームと閉じるボタンが正しくレンダリングされず、情報ウィンドウがマップから外れている、つまりマーカーに接続されていません。アイデアはありますか？よろしくお願いします。 – IRHM
