Ext
我刚开始学Ext，为什么不行啊。什么都出不来啊。
<link rel="stylesheet" type="text/css" href="ext-3.0-rc1.1/ext-3.0-rc1.1/resources/css/ext-all.css"/>
<script type="text/javascript" src="ext-3.0-rc1.1/ext-3.0-rc1.1/ext-all.js"></script>
<script type="text/javascript" src="ext-3.0-rc1.1/ext-3.0-rc1.1/adapter/ext/ext-base.js"></script>
<script>
  Ext.onReady(function(){
  var win=new Ext.Window({
  title:"第一个Ext应用",
  width:400,
  height:300,
  buttons:[{text:"确定"},{text:"取消"}]
  })
  win.show();
  })
</script>

------解决方案--------------------
<script type="text/javascript" src="ext-3.0-rc1.1/ext-3.0-rc1.1/ext-all.js"> </script>
<script type="text/javascript" src="ext-3.0-rc1.1/ext-3.0-rc1.1/adapter/ext/ext-base.js"> </script> 
这2个加载顺序换一下试试
