织梦CMS实现键盘翻页效果

对于小说站、文献站点而言，支持鼠标翻页能大大提高用户体验。那么，织梦cms怎样实现键盘翻页呢？

<script type="text/javascript" language="javascript">
<!--
document.onkeydown=nextpage;
var prevpage='{dede:prenextget='pre'/}';
var nextpage='{dede:prenextget='next'/}';
var index_page="index.html";
//varbookpage="index.html";
functionnextpage(event)
{
event=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=newXMLHttpRequest();
if(http_request.overrideMimeType){
http_request.overrideMimeType('text/xml');
}
}elseif(window.ActiveXObject){//IE
try{
http_request=newActiveXObject("Msxml2.XMLHTTP");
}catch(e){
try{
http_request=newActiveXObject("Microsoft.XMLHTTP");
}catch(e){}
}
}
if(!http_request){
alert('Givingup:(CannotcreateanXMLHTTPinstance)');
returnfalse;
}
returnhttp_request;
}
</script>
