私は初心者の Sencha ユーザーです。タブ パネルをコーディングし、各テーブル内にフォームを配置します。mainForm 変数を定義して 2 タブに配置しようとしましたが、2 タブ ボタンをクリックすると空白のパネルが返されました....

私が間違っていることは何ですか？ありがとうございました。

あなたはそれを間違ってやっています。

それを配列mainForm内にネストしています。items[]そうであってはなりません。

代わりに、各項目を個別に作成し、TabPanel の項目配列に追加します。

デモ ： -

Ext.Loader.setConfig({
    enabled: true
});

Ext.application({
    name: 'SenchaFiddle',

    launch: function() {
         var mainForm = Ext.create('Ext.form.Panel', {
            fullscreen: true,
            title:'2-tab',
            items: [
                {
                    xtype: 'textfield',
                    name : 'name',
                    label: 'Name'
                },
                {
                    xtype: 'emailfield',
                    name : 'email',
                    label: 'Email'
                },
                {
                    xtype: 'passwordfield',
                    name : 'password',
                    label: 'Password'
                }
            ]
        });

        var htmlForm1 = Ext.create('Ext.form.Panel',{
              title: '1-tab',

              //next we give it some simple html
              items: {
                 html: '1',
                 centered: true
              },

              //then a custom cls so we can style it
              cls: 'card1'
         });

         var htmlForm3 = Ext.create('Ext.form.Panel',{
             title: '3-tab',

              //next we give it some simple html
             items: {
                html: '3',
                centered: true
             },

             //then a custom cls so we can style it
             cls: 'card3'
         });

        Ext.Viewport.add({
            //first we define the xtype, which is tabpanel for the Tab Panel component
            xtype: 'tabpanel',

            //next we define the items that will appear inside our tab panel
            items: [htmlForm1,mainForm,htmlForm3]
        });
    }
});
