extjs最新版，可从http://www.extjs.com/官方网下载，下载包解压后docs目录里，就是API文档，samples目录里是示例
今天接触了下ExtJs，确实不错，先来一个最经典的Hello World.

var fHelloWorld = function (){
Ext.MessageBox.show({
title: " ExtJs Study " ,
msg: " Hello World " ,
width: 200 ,
buttons: Ext.MessageBox.OK
});
}
// 这就是Ext获取页面元素的方法，简单吧
var oBtnHello = Ext.get( " btnHello " );
// 将元素居中
oBtnHello.center();
// 为元素动态增加Click事件
oBtnHello.on( " click " , fHelloWorld)
});

解释:
所有功能都是在Ext.onReady中完成的，用了几个简单的方法，Ext.get取页面指定ID的元素,center()将对象居中,MessageBox.show显示对话框
最后运行效果如下:
