如果有任何 ExtJS 方式可以加载存储数据并且加载后我可以在主面板中创建其他我的组件(自定义面板)以我的特定方式显示该数据,我会徘徊吗?

我想用我的自定义组件在面板中显示数据
你有两个选择:
要复制 dataview 的文档示例(选项 1):
Ext.define('Image', {
    extend: 'Ext.data.Model',
    fields: [
        { name:'src', type:'string' },
        { name:'caption', type:'string' }
    ]
});
Ext.create('Ext.data.Store', {
    id:'imagesStore',
    model: 'Image',
    data: [
        { src:'http://www.sencha.com/img/20110215-feat-drawing.png', caption:'Drawing & Charts' },
        { src:'http://www.sencha.com/img/20110215-feat-data.png', caption:'Advanced Data' },
        { src:'http://www.sencha.com/img/20110215-feat-html5.png', caption:'Overhauled Theme' },
        { src:'http://www.sencha.com/img/20110215-feat-perf.png', caption:'Performance Tuned' }
    ]
});
var imageTpl = new Ext.XTemplate(
    '<tpl for=".">',
        '<div style="margin-bottom: 10px;" class="thumb-wrap">',
          '<img src="{src}" />',
          '<br/><span>{caption}</span>',
        '</div>',
    '</tpl>'
);
Ext.create('Ext.view.View', {
    store: Ext.data.StoreManager.lookup('imagesStore'),
    tpl: imageTpl,
    itemSelector: 'div.thumb-wrap',
    emptyText: 'No images available',
    renderTo: Ext.getBody()
});
