本例没有采用Sencha的mvc模式。只是一个简单的读取加载本地Json数据示例。
文档结构如下:
app.js代码如下:
Ext.require([‘Ext.form.Panel‘, ‘Ext.data.Store‘, ‘Ext.data.reader.Json‘, ‘Ext.dataview.DataView‘]); Ext.application({ name:‘MyApp‘, icon:‘images/icon.png‘, glossOnIcon:false, phoneStarupScreen:‘images/starUp.png‘, tabletStartupScreen:‘images/tablet.png‘, launch:function(){ Ext.define(‘User‘,{ extend:‘Ext.data.Model‘, config:{ fields:[ {name:‘id‘,type:‘string‘}, {name:‘name‘,type:‘string‘}, {name:‘img‘,type:‘string‘}, {name:‘age‘,type:‘string‘}, {name:‘url‘,type:‘string‘}, {name:‘email‘,type:‘string‘}, {name:‘info‘,type:‘string‘} ] } }); var userStore=Ext.create(‘Ext.data.Store‘,{ model:‘User‘, autoLoad:true, proxy:{ type:‘ajax‘, url:‘userInfo.json‘, reader:{ type:‘json‘, rootProperty:‘users‘ } } }); var userTemplate = new Ext.XTemplate( ‘<tpl for=".">‘, ‘<div class="user_img"><img src="{img}" width="50" height="50" />编号:{id}<br/>姓名:{name}<br/>年龄:{age}<br/>主页:{url}<br/>邮件:{email}<br/>个人信息:{info}</div>‘, ‘</tpl>‘ ); var dataview=Ext.create(‘Ext.DataView‘,{ store:userStore, itemTpl:userTemplate, listeners:{ itemtap:function( ok, index, target, record, e, eOpts){ alert(record.get("name")); } } }); Ext.Viewport.add(dataview); } });
index.html文件如下:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>index.html</title> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <link rel="stylesheet" type="text/css" href="sencha-touch.css"> <script type="text/javascript" src="sencha-touch-all-debug.js"></script> <script type="text/javascript" src="app.js"></script> </head> <body> </body> </html>
userInfo.json文件如下:
{ "success":true, "users":[{ "id":"1", "name":"张三", "img":"images/user.jpg", "age":"23", "url":"http://zahngsan.com", "email":"waj@163.com", "info":"a good boy" },{ "id":"2", "name":"李四", "img":"images/user.jpg", "age":"23", "url":"http://lisi.com", "email":"waj@163.com", "info":"a good boy" },{ "id":"3", "name":"王五", "img":"images/user.jpg", "age":"23", "url":"http://henghui.com", "email":"waj@163.com", "info":"a good boy" },{ "id":"4", "name":"赵六", "img":"images/user.jpg", "age":"23", "url":"http://henghui.com", "email":"waj@163.com", "info":"a good boy" },{ "id":"5", "name":"钱七", "img":"images/user.jpg", "age":"23", "url":"http://henghui.com", "email":"waj@163.com", "info":"a good boy" }] }然后再web.xml中配置好默认首页为index.html。
直接打开index.html或者使用服务器方式访问。
