织梦系统实现按键盘方向键实现上一篇下一篇翻页

<SCRIPT language=>
document.onkeydown = pageEvent;
var prevpage="http://www.111cn.net/";
var nextpage="http://www.111cn.net/";
function pageEvent(evt){
evt = evt ||window.event;
var key=evt.which||evt.keyCode;
if (key == 37) location = prevpage
if (key == 39) location = nextpage
};
</SCRIPT>

<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;

alert('这是第一页');
}
if (event.keyCode==39)

function getElement(aID)
