Action中：
public ActionForward selectAll(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
MovieDetailForm mdf=new MovieDetailForm();
String county=request.getParameter("county");
String movieName=request.getParameter("movie_name");
System.out.println(county+"%%%%%"+movieName);
}
JSP中部分代码：
<script type="text/javascript">
function search(){
var moviename=document.getElementById("movieName").value;
var County=document.getElementById("county2").value;
alert(moviename);
alert(County);
document.getElementById("county2").value=county;
document.getElementById("movieName").value=movie_name;
document.formx1.submit();
}
</script>

------解决思路----------------------
你把那个form里的2个隐藏域显示出来测试看看，看提交时是否有值。
我看那2个都没给设置id,也没赋值进去。
