我无法在我编写的以下 sencha-touch 代码中找出问题所在。它没有显示任何错误，但是当我运行它时，它仍然不起作用。应用程序还需要更多文件或类吗？我正在使用 linux 机器在 chrome 上运行它。
var App = new Ext.application({
requires: [
'Ext.tab.Panel' ,'Ext.List', 'Ext.data.Store', 'Ext.data.Model'
],

Ext.regModel('note',{
idProperty:'id',

{name : 'narrative' , type:'string'}],

{type: 'presence', field: 'title'} ]
});
Ext.regStore('notestore', {

var notelist= new Ext.List({
