struts2 radio标签 取值

Question

<s:radio list="#{'nickname':'昵称','stdNo':'学号','fileNo':'文件 } name="searchCondition" value="'nickname'" />
<s:submit value="查找" onclick="listFiles(searchCondition.value,searchKey.value)"/>通过alert();显示searchCondition的值发现是undefined，请问各位应该如何从radio标签中取值？

Answer 1

用document.forms[0]. searchCondition.value取值！

Answer 2

用ID<s:radio list="#{'nickname':'昵称','stdNo':'学号','fileNo':'文件 } name="searchCondition" value="'nickname'"  id="searchCondition"/> 
document.forms[0]. searchCondition.value

Answer 3

仍旧不行，这次都不弹出alert()了，直接跳转到我的项目的登录页面了
