相应的xml配置：
</package>
<package name="ajax" extends="json-default">
<action name="rv" class="com.niit.action.RegisterValidate">
<result type="json"></result>
<param name="root">msg</param>
</action>
</package>
其中usermanager.vUser(username)没有问题，因为可以输出"username ok"，但就是不执行 alert(data);

你反回的是 return SUCCESS; 这个
配置却是这样
<package name="ajax" extends="json-default">
<action name="rv" class="com.niit.action.RegisterValidate">
<result type="json"></result>
<param name="root">msg</param>
</action>
</package>
你不觉得奇怪么
