这个功能在很多小说站，图片站经常用到，大家可以留意一下，此教程源自于论坛热心网友提供，下面来讲讲具体的修改操纵：

首先我们打开 include/arc.archives.class.php 查找到以下代码：

$this->PreNext['pre'] = "上一篇：<a href='$mlink'>{$preRow['title']}</a> ";

替换成以下代码：

$this->PreNext['pre'] = "$mlink ";
$this->PreNext['next'] = "下一篇：<a href='$mlink'>{$nextRow['title']}</a> ";

这样php代码就修改完了可以保存，接下来我们在内容页用js进行调用．把以下代码：

<script type="text/javascript" language="javascript">
< !--document.onkeydown = nextpage;
var prevpage = '{dede:prenext get='pre '/}';
var nextpage = '{dede:prenext get='next '/}';
var index_page = "index.html";
//var bookpage="index.html";
function nextpage(event) {
eventevent = event ? event: (window.event ? window.event: null);
//if (event.keyCode==13) location=bookpage
if (event.keyCode == 13) location = index_page
if (event.keyCode == 37) {
if (prevpage != '' && prevpage != '上一篇：没有了 ') location = prevpage;
else alert('这是第一页');
}
if (event.keyCode == 39) {
if (nextpage != '' && nextpage != '下一篇：没有了 ') location = nextpage;
else alert('已经是最后一页了');
}
}
//-->
function getElement(aID) {
return (document.getElementById) ? document.getElementById(aID) : document.all[aID];
}
function makeRequest(url) {
http_request = false;
if (window.XMLHttpRequest) { //Mozilla,Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
}
} else if (window.ActiveXObject) { //IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch(e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {}
}
}
if (!http_request) {
alert('Giving up:(Cannot create an XMLHTTP instance)');
return false;
}
return http_request;
}
</script>
