谁知道怎么在javascript里调用jsp参数啊？

Question

<%String para1="abc" ;
  String para2="def" ;%>
<script>
function window.onload(){
   alert(document.f.h1.value) ;
   alert(document.f.h2.value) ;
}
</script>
<form name=f>
<input type=hidden name=h1 value=<%=para1%>>
<input type=hidden name=h2 value=<%=para2%>>
</form>

<input type = "hidden" name = "txtDate" id = "txtDate" value = "<%=request.getParameter("p_Date")%>">or
<script>
var today="<%=request.getParameter("p_Date")%>";
.
.
</script>

Answer 2

<%jspValue=request.getAttribute("result");%>
<script>
var jsValue=<%=jspValue%>
</script>

Answer 3

谢谢老兄!不过我还有疑问:
<script lanugage="javascript">
function linktopage()
{
  IDCARD=document.form1.test1.value;
  pageCount=document.from1.pageCount.value;
  sqlcount=document.form1.sqlcount.value;
  currPage=document.form1.currPage.value;
   document.form1.submit();
}
</script>
<script lanugage="javascript">
function form2()
{
  IDCARD=document.form2.test1.value;
  pageCount=document.form2.pageCount.value;
  sqlcount=document.form2.sqlcount.value;
  currPage=document.form2.currPage.value;
    currPage=currPage-1+2;
}
</script>
 <%if(currPage>1){%>
  <a href="javascript:form1()">上一页</a> 
  <%}%>
  <%if(currPage<pageCount){%>
  <a href="javascript:form2()"> 
  下一页</a> 
  <%}%>
为什么点下一页好用?上一页错误:不支持此方法呢?还有,为什么必须用 window.location="mytest.jsp?IDCARD="+IDCARD+"&page="+page+"&sqlcount="+sqlcount+"";可用?而document.form.submit();却查不到信息呢?
其实我用form的目的就是隐藏参数,如果用window.location的话就失去意义了!急!!!!
