支持extjs3版本的uploadPanel请在http://czpae86.iteye.com/里面找。
一，注意：
1，服务端上传成功返回:
{success:true}{success:false}3，使用方法：
Ext.create('Ext.ux.uploadPanel.UploadPanel',{
title : 'UploadPanel for extjs 4.0',
addFileBtnText : '选择文件...',
uploadBtnText : '上传',
removeBtnText : '移除所有',
cancelBtnText : '取消上传',
file_size_limit : 10000,//MB
upload_url : 'upload.do'
});4，截图：
