Question

当我尝试在窗口（Ext.Window）中组合不同的组件（下拉列表，网格，按钮等）时，不显示网格。以下是代码：

    <script type="text/javascript">

Ext.onReady(function () {
    Ext.define('SuperUser', {
        extend: 'Ext.data.Model',
        fields: [
            { name: 'fname', type: 'string' },
            { name: 'lname', type: 'string' },
            { name: 'email', type: 'string' },
            { name: 'uid', type: 'string' },
            { name: 'isSup', type: 'boolean' },
            { name: 'upDate', type: 'string' },
            { name: 'upBy', type: 'string' }
        ]
    });

    var win=new Ext.Window({
        title: 'Super User Access Management',
        border:false,
          items       : [  
          {
          xtype      : 'combo',
          fieldLabel : 'Module',
          value: 'Super Admin' ,
          store: ['Super Admin', 'Partner Contact Management', 'Partner Trainning Management'],
          listeners: {
              select: function(){
               alert('Hello module!');
              }
            }        
            },
            { 
                xtype: 'gridpanel',
                border: false,
                store: Ext.create('Ext.data.Store', {
                    storeId: 'supUserStore',
                    pageSize: 3,
                    model:'SuperUser',
                    data: [
                            { fname: 'Jane',lname:'Smith',email: 'j.smith@netapp.com', uid: 'jsmith',isSup:false,upDate:'11-19-2012',upBy:'aaron@netapp.com' },

                            { fname: 'Jim',lname:'Smith',email: 'jm.smith@netapp.com', uid: 'jmsmith',isSup:true,upDate:'11-23-2012',upBy:'aaron@netapp.com'}
                        ],
                    proxy: { type: 'memory', reader: { type: 'json', root: 'data',totalProperty:10} }
                }),
                selModel: Ext.create('Ext.selection.CheckboxModel'),
                columns: [
                          { header: 'First Name', dataIndex: 'fname' },
                          { header: 'Last Name', dataIndex: 'lname' },
                          { header: 'Email', dataIndex: 'email' },
                          { header: 'User ID', dataIndex: 'uid' },
                          { header: 'Super Admin', dataIndex: 'isSup' },
                          { header: 'Updated Date', dataIndex: 'upDate' },
                          { header: 'Updated By', dataIndex: 'upBy' }
                      ],
                      dockedItems: [{
                          xtype: 'pagingtoolbar',
                          store: Ext.data.StoreManager.lookup('supUserStore'),   
                          dock: 'bottom',
                          displayInfo: true
                      }],
                      initComponent: function () {
                          this.callParent(arguments);

                      }
                }

            ]
    });
    win.show();

}); 
    </script>
</head>
<body>

</body>
</html>

请告诉我，我做错了。或者让我知道，我如何在EXTJS中组合不同的组件。我不想在html体中的div标签中呈现不同的组件。

删除网格配置中的initComponent方法。如果您需要覆盖现有方法，请使用Ext.define创建子类，以便callParent按预期工作。

关于您的代码的几条评论（与您的问题无关）：

创建商店并在同一配置对象中引用它是iffy。您应该在配置之外创建商店并使用store: "supUserStore"而不是自己进行StoreManager查找。
网格列上的header属性已弃用一段时间。首选属性称为text。
您可以使用win.show()配置，而不是在创建窗口后调用autoShow: true。
