我正在 sencha touch 中开发一个应用程序，我是这项技术的新手首先看我的代码

查看-->Main.js

Ext.define('DealsList.view.Main', {
    extend: 'Ext.Container',
    xtype: 'mainlist',
    requires: [
        'Ext.TitleBar',
        'Ext.Toolbar'

    ],
    config: {
        fullscreen:true,
        scrollable:false,
        layout: {
            // type:'fit'

                function(buttonId) {
                    if (buttonId === 'yes') {
                        window.location.reload();
                    }
                }
            );
        }
    });

在我的应用程序的第一个屏幕中，我有一个开始按钮。当我单击此按钮时，它会显示一个列表（listpage.js），我的问题是，当我单击一个列表项时，数据不会移动到下一页（DealsDescription.js）。我的要求是数据移动到下一页并附加到该页面xtype:label（DealsDescription.js 屏幕）

我们大多数人都设置了单页应用程序。因此，您无需刷新页面而是切换卡片（或标签等等......）。这样，您始终可以通过 javascript 获取数据。向上或向下导航组件树。

上：

mycomponent.up() //go up one level
mycomponent.up(selector) //go up till you reach the component meeting the criteria

下：

mycomponent.query(someComponentQuery) //go down and find all components meeting the criteria
mycomponent.getComponent(componentId) //get the (direct) child with given Id

如果你确实想加载一个新页面，你需要一个全新的应用程序。所以你可以使用会话或本地存储在页面之间传输数据。（在您的商店/模型上使用 sessionstorageProxy 或 localstorageProxy）。

基本上，您必须在视图的配置中声明一个数据持有者变量，并且在创建此视图时，您可以使用所需的任何数据对其进行初始化。

var myView = Ext.create('DealsList.view.DealsDescription', {
  rec : someData //this would contain all data
});

然后在初始化时你可以这样访问rec：

var data = this.config.rec;

然后您可以创建所有内部组件并添加到此视图的容器中。

var items = [{
  xtype:'toolbar',
  docked:'top',
  title:'SampleDeals',
  items:[
      {
      xtype:'button',
      id:'backbutton',
      ui:'back',
      text:'back'

      }
  ]
  },
  {
  xtype:'label',
  html: '<h1>'+data.subcategoryname+'</h1>'
  }];
  this.setItems(items);
