一、什么是Sencha Touch？

Sencha Touch是一个应用手持移动设备的前端js框架，与extjs是同一个门派的，它继承了extjs的优点和缺点。功能很强大，效果很炫丽，效率不高。

二、例子来了

效果图：Sencha touch官方一个list的example

PS：模拟器访问本地server的地址是10.0.2.2:8080，而不是127.0.0.1:8080

1、导入touch的相关js，css以及资源文件

2、index.html

   1: <!DOCTYPE html>
   2: <html>
   3: <head>
   4:     <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
   5:     <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=0;" />
   6:     <title>Sencha Touch List Example</title>
   7:     <!-- import touch css and js -->
   8:     <link rel="stylesheet" href="touch/resources/css/sencha-touch.css" type="text/css">
   9:     <script type="text/javascript" src="touch/sencha-touch-debug.js"></script><script type="text/javascript" src="src/index.js"></script>
  10: </head>
  11: <body></body>
  12: </html>

3、index.js
