1 Struts2+jQuery+JSON实现异步交互

2? 主题：[原创]Struts2 + JQuery + JSON实现AJAX
http://www.iteye.com/topic/560638
说明:主要参考了 Struts2+jQuery+JSON实现异步交互 文章,只不过原作者使用Struts2版本是是:2.1.8及json-lib.2.1.jar,在Struts2中的插件: struts2-json-plugin-2.2.1.1.jar已经不在需要json-lib.jar了,Jquery为1.5.1,在此表示向你感谢!学会了Struts2+jQueryJSON
一 环境:XP+Myeclipse6.6+WebLogic92+JDK1.5
二 具体步骤如下:
所需要的jar文件为:struts2-json-plugin-2.2.1.1.jar加入WEB-INF/lib下
所有代码引用Struts2+jQuery+JSON实现异步交互的代码,请理解!
