-- [求助]其实是非常简单的问题，哪位高手帮忙调试下。感激不尽
书上的例子。怎么都说我这一行有错误 objbook没有定义。但先显示书本信息再翻页就没有问题。 哪位高手帮忙调试下错误到底出在哪里？
if((pageno)<(objbook.RecordCount)/tblbook.dataPageSize) 源代码： <XML id="XMLDSO" src="code7_6.xml"></XML>
<html>
<head>
<title>分页分条显示书本信息</title>
</head>
<script language=JavaScript>
var pageno=1;
function SelectRecord(Element)
{
//获取记录号
RecordNo = Element.parentElement.rowIndex;
objbook = XMLDSO.recordset;
objbook.absoluteposition = RecordNo+(pageno-1)*tblbook.dataPageSize;
title.innerHTML =objbook("title").value;
bookcategory.innerHTML = objbook("bookcategory").value;
ISBN.innerHTML = objbook("ISBN").value;
author.innerHTML = objbook("author").value;
publisher.innerHTML = objbook("publisher").value;
price.innerHTML = objbook("price").value;
remain.innerHTML = objbook("remain").value;
}
function pre_page()
{
if (pageno>1)
{ tblbook.previousPage();
pageno=pageno-1;}
}
function next_page()
{
if((pageno)<(objbook.RecordCount)/tblbook.dataPageSize)
{ tblbook.nextPage();
pageno=pageno+1;}
}
