ASP实现静态无刷新分页效果

关注+2009-11-02作者：

在WIN200+ACCESS可以正常运行
最近在网站看到AJAX分页效果很少，多数不能直接用，现将这给分享大家，请大家多指教。

建一个文件list.htm

<html>
<head>
<title>新闻列表简化型</title>
<script language="javascript">
<!--
//ajax 控件也可以做成单独文件方便到其它地方调用
function Ajax()
{
var xhrObj=null;
if(window.XMLHttpRequest)
{
xhrObj=new XMLHttpRequest();
}
else if(window.ActiveXObject)
{
try{
xhrObj=new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e1)
{
try{
xhrObj=new ActiveXObject("MSXML2.XMLHTTP");
}
catch(e2){
try{
xhrObj=new ActiveXObject("MSXML3.XMLHTTP");
}
catch(e3){
alert("创建Ajax失败："+e3)
}
}
}
}
else
{
alert("未能识别的浏览器");
}
return xhrObj;
}

function $(id)
{
return document.all[id];
}

</script>
<script language="javascript" defer>
   var xhr=new Ajax();
   var page=0;
   var icount=0;   //当前页数
   var pagecount; //总页数
   var count=0;
   var ipagecount=0;
   var ipagesize=5;; //每页显示记录数
   var pp=0;
   var ipage=0;
   var Dom=null;

   function $showList()
   {
var html="";
var items=Dom.selectNodes("//item");
icount=Dom.selectNodes("//item").length;                    //数量
count=Dom.selectSingleNode("//data").getAttribute("count"); //总数量
      ipagecount=parseInt((icount-1)/ipagesize)+1;
pagecount=parseInt((count-1)/ipagesize)+1;
startPosition=(page-1)*ipagesize;
endPosition=(page*ipagesize)
if(endPosition>count)endPosition=count
for(var i=startPosition;i<endPosition;i++)
{
     html+="<div id=\"title\"><a href=\""+items[i].selectSingleNode("htmlurl").text+"\">"+items[i].selectSingleNode("hits").text+"</a></div>";
}
$("newsList").innerHTML=html;

   function nextPage()
   {
      if(page<ipagecount)
{
      getList(page+1);
}
else
{
     alert("已经到最后一页了");
}
   }

   function turnPage(p)
   {
           getList(p);
   }

getList(1);
</script>
</head>
<body>
<div id="newsList"></div>
<div id="pagestatus"></div>
</body>
</html>

建一个文件data.asp
注：这里我用的是ACCESS数据库，库名叫data.mdb，当然这个自己可以定义，库中表名为info字段分别是id(自动编号)、a、b、c、d(日期类型)

<%@ Language="VBSCRIPT" codepage="936" %>
<%
response.cachecontrol="no-cache"
response.addHeader "pragma","no-cache"
response.expires=-1
response.expiresAbsolute=now-1
response.contentType="text/xml"
'SQL数据库 Set conn=server.CreateObject("adodb.connection")
'sconn="driver={sql server};server=(local);uid=**;pwd=**;database=***"
'conn.open sconn
set conn=server.CreateObject("adodb.connection")
file=server.mappath("data.mdb")
conn.Open "driver={microsoft access driver (*.mdb)};"&"dbq="&file%>
<?xml version="1.0" encoding="gb2312" ?>
<%
dim iPagesize,rs,sSQL,iCurPage,ipresize,icount,ipagecount

icurpage=trim(request.QueryString("curpage"))

iPagesize=500 '页大小
set rs=server.createObject("adodb.recordset")
'rs.open "select count(id) from ca_news where status=1",conn,1,1
rs.open "select count(id) from info",conn,1,1
icount=rs(0) '总记录数
rs.close

ipagecount=int((icount-1)/iPagesize)+1 '总页数
if icurpage="" then
    icurpage=1
else
    icurpage=cint(icurpage)
end if
if icurpage<1 then
   icurpage=1
end if

if icurPage>ipagecount then icurpage=ipagecount
ipreSize=(iCurPage-1)*ipagesize
if ipresize=0 then
sSQL="select * from info order by id desc"
else
' sSQL="select top "&ipagesize&" id,title,postdate,hits,htmlurl from news where status=1 and id not in (select top "&ipresize&" id from news where status=1 order by id asc) order by id asc"
sSQL="select top "&ipagesize&" * from info id not in (select top "&ipresize&" id from info order by id desc) order by id desc"
end if
rs.open sSQL,conn,1,1

%>
<data count="<%=icount%>" pagesize="<%=ipagesize %>" pagecount="<%=ipagecount%>">
<%
   while not rs.eof
%>
    <item id="<%=rs("id")%>">
        <title><![CDATA[<%=rs("a")%>]]></title>
<htmlurl><![CDATA[<%=rs("b")%>]]></htmlurl>
        <postdate><%=DateValue(rs("d")) %></postdate>
        <hits><%=trim(rs("c")) %></hits>
    </item>
<%
   rs.movenext
wend
%>
</data>
<%
rs.close
set rs=nothing
conn.close
set conn=nothing
%>
