ps:如果把action的方法名改为execute，把struts.xml配置文件里的method="check"去掉，则可以运行，不报错。

可能是因为你data对象中的 userName 值为null所致


  data:{

     'userName' : userName

  },

使用struts2动态方法
<!-- 动态方法 -->
<constant name="struts.enable.DynamicMethodInvocation" value="true" />

通过checkName!check.do访问。

不清楚 url:"checkName.check.do", 是什么意思
struts2默认处理的是后缀为.action 的请求，用.do要在配置文件中配置

public String jsonAction() {

      PrintWriter writer = response.getWriter();

      String json= 组织json字符串();

      writer.write(json);

      return null;

}

配置文件action里不用配置<result>
直接写<action XXX></action>
action类里把你需要的json对象用字符串拼接起来 然后write到页面
return null 就可以了

我觉得是你 传参有问题
在JavaScript里面 自己多调试下 看看吧

应该在你的struts.xml配置出错了吧.检查一下CheckNameAction 中的result

你的这个url:"checkName.check.do",
应该把.check去掉吧
你已经配置了checkName调用的方法是check了

[Quote=引用 1 楼 allyzhou 的回复:]

No result defined for action com.xpow.hodo.web.action.ajax.CheckNameAction and result success
没有为CheckNameAction 配置success的路径，去struts.xml中看看为CheckNameAction 配置的结果界面吧
[/Quote]

返回的是json值，不跳转、转发页面的！
