海上灾难电影2022:javascript 里是否有个PageForm内置对象？

<%@ page contentType="text/html; charset=GBK"%>
<script language="JavaScript">
<!--
function Jumping(){
document.PageForm.submit();
return ;
}

function gotoPage(pagenum){
document.PageForm.jumpPage.value = pagenum;
document.PageForm.submit();
return ;
}

-->
</script>

<table bgcolor="#C4E669" border="0" cellspacing="2" cellpadding="0" align="center" width="92%">
<tr align="center"><td align="center">
<%=pageBean.getRowsPerPage()%>个记录每页||
总记录:<%=pageBean.getMaxRowCount()%>||
当前页:<%=pageBean.getCurPage()%>||
总页数:<%=pageBean.getMaxPage()%>||

<%if(pageBean.getCurPage()==1){
out.print("<img height=19 align=absMiddle border=0 src=\"/mvc/images/goFirst.gif\"> <img height=19 border=0 align=absMiddle src=\"/mvc/images/goPrev.gif\">");
}else{ %>
<A HREF="javascript:gotoPage(1)"><img border=0 height=19 src="/mvc/images/goFirst.gif" align=absMiddle class="img_btn"></A>
<A HREF="javascript:gotoPage(<%=pageBean.getCurPage()-1%>)"><img height=19 src="/mvc/images/goPrev.gif" align=absMiddle border=0 class="img_btn"></A>
<%}%>

<%if(pageBean.getCurPage()==pageBean.getMaxPage()){
out.print("<img border=0 align=absMiddle height=19 src=\"/mvc/images/goNext.gif\"> <img border=0 align=absMiddle height=19 src=\"/mvc/images/goLast.gif\">");
}else{ %>
<A HREF="javascript:gotoPage(<%=pageBean.getCurPage()+1%>)"><img height=19 src="/mvc/images/goNext.gif" border=0 class="img_btn" align=absMiddle ></A>
<A HREF="javascript:gotoPage(<%=pageBean.getMaxPage()%>)"><img height=19 src="/mvc/images/goLast.gif" border=0 class="img_btn" align=absMiddle ></A>
<%}%>

跳到第 <SELECT name="jumpPage" onchange="Jumping()">
<%for(int i=1;i<=pageBean.getMaxPage();i++) {
if (i== pageBean.getCurPage()){
%>
<OPTION selected value=<%=i%>><%=i%></OPTION>
<%}else{%>
<OPTION value=<%=i%>><%=i%></OPTION>
<%}
}%>
</SELECT>页
</td></tr>

我明白了，不好意思，我少下了个jsp,不过二楼的我说的是javascript 不是jsp.
