DEDECMS实现按键盘方向键实现上一篇下一篇翻页

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>
