使用Sencha Touch加载本地Json数据

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:

mamicode.com,码迷

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。
