上下左右键翻页
<SCRIPT language=javascript>
document.onkeydown = pageEvent;
var prevpage="http://www.offid.cn/";
var nextpage="http://www.offid.com/";
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 language="javascript">
document.onkeydown=keypage
var prevpage="bencandy.php?fid=$backdb[fid]&id=$backdb[aid]"
var nextpage="bencandy.php?fid=$nextdb[fid]&id=$nextdb[aid]"
function keypage() {
if (event.keyCode==37) location=prevpage
if (event.keyCode==39) location=nextpage
}
</script>
上下翻页：
<script language="javascript">
document.onkeydown=keypage
var prevpage="bencandy.php?fid=$backdb[fid]&id=$backdb[aid]"
var nextpage="bencandy.php?fid=$nextdb[fid]&id=$nextdb[aid]"
function keypage() {
if (event.keyCode==38) location=prevpage
if (event.keyCode==40) location=nextpage
}
</script>

可以把这段代码加bencandy.htm
<!--
<?php
$backdb[subject] || ($backdb[subject]="没有了") && ($backdb[click]="return false;");
$nextdb[subject] || ($nextdb[subject]="没有了") && ($nextdb[click]="return false;");
