Sencha-touch 2 - 在標籤面板內形成

Question

我是新手Sencha用戶。我會編寫一個tab面板，並在每張表格中放入一個表格。 我嘗試定義MainForm的變種，並把2標籤，但如果我點擊2選項卡上的按鈕，我已經回到一個空白麪板....

我做錯了嗎？ 謝謝。

你做得不對。

您正在將mainForm嵌套在items[]陣列中。它不應該是這樣。

而是分別創建每個項目並添加到TabPanel的項目數組中。

演示： -

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] 
     }); 
    } 
});
