Dedecms實(shí)現(xiàn)鍵盤(pán)上下翻頁(yè)的功能，圖片站經(jīng)常用到，大家可以留意一下，此教程源自于dede論壇熱心網(wǎng)友提供，下面來(lái)講講具體的修改操縱：
首先我們打開(kāi) include/arc.archives.class.php
查找到以下代碼：
$this->PreNext['pre'] = “上一篇：<a href=’$mlink’>{$preRow['title']}</a> “;
替換成以下代碼：
$this->PreNext['pre'] = “$mlink “;
$this->PreNext['next'] = “下一篇：<a href=’$mlink’>{$nextRow['title']}</a> “;
這樣php代碼就修改完了可以保存，接下來(lái)我們?cè)趦?nèi)容頁(yè)用js進(jìn)行調(diào)用．現(xiàn)把以下代碼：
<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：沒(méi)有了 ‘)
location=prevpage;
else
alert(‘這是第一頁(yè)’);
}
if (event.keyCode==39)
{
if (nextpage!=” && nextpage!=’下一篇：沒(méi)有了 ‘)
location=nextpage;
else
alert(‘已經(jīng)是最后一頁(yè)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>
加到<body>之前的位置．這樣就全部修改完了，之后我們更新文檔看看效果
