私はsencha touch 2を使用してストアを見つけることに取り組んでおり、このリンクをたどります https://developers.google.com/maps/articles/phpsqlsearch_v3

今、私はいくつかのJavascript + htmlファイルのコードを以下のように示しています:-

 <script type="text/javascript">

ほとんどすべてのコードを sencha touch に変換しましたが、代わりに機能しません。ここに私のコードがあります

だから、私に何ができるか提案させてください。どんな助けでも大歓迎です

マップの例を機能させてください:マップの例

その出発点から、必要な機能を追加できるはずです。

Sencha-Touch マップ オブジェクトを使用してマップをセットアップする必要があります。
