正しいログイン後に次のビューにスライドする単純なログインフォームがあります。私が見つけた2つの例の組み合わせ。MVC パターンを使用して、このログインを複数のファイルに分割したいと考えています。私が Web で見た多くの例では、これは Sencha Touch 2 のケーキです。何を試しても、うまくいきません。私は Flex、Java、ActionScript、Php でプログラミングすることに慣れていますが、Sencha jSon はまったく別の球技です。誰でもこれで私を助けることができますか?モデル、ストア、ビュー、およびコントローラーのパッケージを、推奨されるフォルダー構造に配置したいと考えています。

-app
  -controller
    -Controller.js
  -model
    -Model.js
  -store
    -Store.js
  -view
    -Main.js
    -Login.js
    -SecondView.js
-app.js
-app.css
-index.html

これは、ログイン要求に応答する単純な php スクリプト (login.php) です。

Sencha Touch 2 の MVC アプリケーションについて理解するには、このビデオをご覧になることを強くお勧めします。

このビデオには、状況に応じて適用できるフォームの処理の例があります。

MVC の要点は、ロジックを分解することです。問題の app.js にすべてのロジックを保持することの何が問題なのかはわかりません。しかし、さまざまな例を見た後、app.js は大きなファイルではなく短いファイルであることがわかりました。ロジック部分を他のさまざまなファイル (Controller ロジックから controller.js など) に移動して、もう一度やり直してください。
私がすぐに指摘できる1つの例は、次のコードです

var formBase = {
    url: 'login.php',
    standardSubmit: false,
    title:"Login",
    items: [
        {
            xtype: 'fieldset',
            title: 'MyCompony',
            instructions: 'Log in with username and password.',
            defaults: {
                ...
            },
            items: [
                {
                    xtype: 'textfield',
                    ...
                },
                {
                    xtype: 'passwordfield',
                    ...
                }
            ]
        },
        {
            xtype: 'toolbar',
            ...
            items: [
                {xtype: 'spacer'},
                {
                    ...
                },
                {
                    text: 'Login',
                    ...
                    handler: function() {
                        ...
                    }
                }
            ]
        }
    ],

view.js にあるはずです。これがMVCの意味です。それがあなたの質問に答えることを願っています。
