关于JS与JSP的传值问题
<%@ page language="java" contentType="text/html; charset=GB2312"
  pageEncoding="GB2312"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB2312">
<script language="JavaScript">
<!-- //
var startTime = new Date();//这里的new Date()换成你后台传递的时间
var EndTime=startTime.getTime()+60*1000;//这个设置倒计时的时间,按毫秒算,也即60*1000就是一分钟
function GetRTime(){
var NowTime = new Date();
var nMS =EndTime - NowTime.getTime();

var nS=Math.floor(nMS/1000) % 60;
 document.getElementById("RemainS").innerHTML=nS;
ns=
setTimeout("GetRTime()",1000);
}
window.onload=GetRTime;
// -->
</script>
<title>Insert title here</title>
</head>
<body>
<div id="CountMsg">倒计时还有:<strong id="RemainS">XX</strong>秒</div>


我想在这里加判断语句
假如时间到了0秒。打印出“OK”!

</body>
</html>




怎么把JS的值传到jsp中啊。。而且要打印出“ok”!

HTML code
<HTML> 
<HEAD> 
<TITLE>   New   Document   </TITLE> 
</HEAD> 
<BODY> 
<html:form   action= "/XXXAction "> 
<table   width= "100% "   height= "230 "   border= "0 "   cellpadding= "0 "   cellspacing= "0 "> 
    <tr> 
        <td> name: <html:text   property= "name "/> </td> 
    </tr> 
    <tr> 
        <td> <input   type= "set "   value= "set "   onclick= "set(); "> </td> 
    </tr> 
</table> 
</BODY> 
</html:form> 
  <script   language= "javascript "> 
        function   set(){ 
            document.XXXForm.name.value= "ok "; 
            return   true; 
        } 
    </script> 
</HTML>

设置全局变量啊


var nS;
function GetRTime(){
var NowTime = new Date();
var nMS =EndTime - NowTime.getTime();
nS=Math.floor(nMS/1000) % 60;
if(nS == 0){
alert("OK")}
 document.getElementById("RemainS").innerHTML=nS;
ns=
setTimeout("GetRTime()",1000);
}
