javascript - 选项卡式工具栏中的 Sencha Touch 列表组件

Question

我正在使用 Sencha 触摸框架和列表项组件。我现在只用了大约两周的时间，我不知道如何让“onItemDisclosure”打开“detailPanel”。我试图遵循这个例子:http://vimeo.com/19245335 。我已将我的代码粘贴在下面。很感谢任何形式的帮助。

    GoW3Guide.views.detailPanel = Ext.extend(Ext.Panel, {
        id: 'detailpanel',
        tpl: 'Hello, {firstName}!',
        dockedItems: [
            {
                xtype: 'toolbar',
                items: [{
                    text: 'back',
                    ui: 'back',
                    handler: function() {
                        GoW3Guide.Viewport.setActiveItem('disclosurelist', {type:'slide', direction:'right'});
                    }
                }]
            }
        ]
    });

    Ext.reg('detailPanel', GoW3Guide.views.detailPanel);


    GoW3Guide.views.listPanel = Ext.extend(Ext.List, {
        id: 'disclosurelist',
        store: GoW3Guide.ListStore,
        itemTpl: '<div class="contact">{firstName} {lastName}</div>',
        grouped: true,
        onItemDisclosure: function(record, btn, index) {
            GoW3Guide.views.detailPanel.update(record.data);
            GoW3Guide.views.Guidescard.setActiveItem('detailpanel');
        }
    });

    Ext.reg('listPanel', GoW3Guide.views.listPanel);



    GoW3Guide.views.Guidescard = Ext.extend(Ext.Panel, {
        fullscreen: true,
        layout: 'card',
        cardSwitchAnimation: 'slide',
        initComponent: function() {
            Ext.apply(this, {
                items: [GoW3Guide.views.listPanel, GoW3Guide.views.detailPanel]
            });
            GoW3Guide.views.Guidescard.superclass.initComponent.apply(this, arguments);
        }
    });
    Ext.reg('guidescard', GoW3Guide.views.Guidescard);

您遇到任何 JavaScript 错误吗？

根据文档，setActiveItem 需要一个组件实例、一个数字(卡片索引)或一个配置对象，例如{xtype:'detailPanel'}

如果您想激活新的详细信息面板，请尝试

GoW3Guide.views.Guidescard.setActiveItem({xtype:'detailpanel'});

或

GoW3Guide.views.Guidescard.setActiveItem(new GoW3Guide.views.detailPanel());
