Main.js代码

    Ext.namespace('Envato', 'Envato.AudioJungle', 'Envato.AudioJungle.Previewer', 'Envato.Stores');
    Ext.setup({
        onReady: function() {
            Envato.AudioJungle.Previewer.displayPanel.render(Ext.getBody()).doComponentLayout();
        }
    })

在移动设备（iphone和ipad）上，工具栏可以很好地渲染，但列表在我更改设备方向之前不会渲染

在chrome上，渲染效果很好。是否有人看到任何可能导致此问题的突出内容？

通过将面板声明为全屏：true，它将在创建时（即在onReady之前）自动呈现到文档正文

不完全确定这是如何解决问题的。你能告诉我零钱是多少吗？就我所见，Envato.AudioJungle.Previewer.displayPanel已经有了“全屏：真”这就是重点。该类是用fullscreen:true声明的，这意味着它将尝试在实例化后立即呈现到文档体。在这种情况下，它在onReady之外。

    Ext.namespace('Envato', 'Envato.AudioJungle', 'Envato.AudioJungle.Previewer', 'Envato.Stores');
    Ext.setup({
        onReady: function() {
            Envato.AudioJungle.Previewer.displayPanel.render(Ext.getBody()).doComponentLayout();
        }
    })

Ext.setup({
    onReady: function(){
        Ext.regModel('Item', {
            fields: ['text']
        });

        new Ext.Panel({
            fullscreen: true,
            layout: 'fit',
            dockedItems: [{
                xtype: 'toolbar',
                items: {
                    text: 'I am a button'
                }
            }],
            items: {
                xtype: 'list',
                itemTpl: '{text}',
                store: new Ext.data.Store({
                    model: 'Item',
                    data: [{
                        text: 'Foo'
                    }]
                })
            }
        });
    }
});
