Dedecms实现键盘上下翻页的功能,图片站经常用到,大家可以留意一下,此教程源自于dede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.现把以下代码:
<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>
加到<body>之前的位置.这样就全部修改完了,之后我们更新文档看看效果
