Google Maps APIを使用しているかどうかを確認する方法

Question

私はタクシーの予約アプリケーションで働いています。これは、検索対象のGoogleマップも表示されています。とdrop locationがあり、の中にconditionが入っています。この周囲。 Googleでこのアドレスを検索すると、赤色のポリゴンが表示されます。しかし、私は、ユーザーの宛先がこの境界線の内側かこの境界線の外側にあるかどうかを調べるためにGoogleでヘルプを見つけられませんでした。

ヒントがあれば大丈夫です。リクエストと誰がコメントを捧げた人に

Check the map here, i want this area cordinates, i want to know if searched location lies inside this area or outside this area

Answer 1

感謝。私は問題を解決し、私はちょうど完全なコードを追加しています、ここに誰かがそれを必要とするかもしれません。

オートコンプリートアドレス用の2つの入力ボックス、場所の検索、およびスクリプトが、選択した場所がポリゴンの内側にあるかどうかを検索します。ポリゴンはユーザーには表示されません。私はそれを望んでいないので、表示する場合は、この行のコメントを削除してくださいpolygon.setMap(map)。スクリプトは経路と期間を表示します。悪い英語で申し訳ありません。
