这个是由asp二级侧拉菜单改的
复制代码 代码如下:
<script language="javascript">
// JavaScript Document
startList = function() {
if (document.all && document.getElementById) {
navRoot = document.getElementById("nav");
for (i=0; i<navRoot.childNodes.length; i++) {
node = navRoot.childNodes[i];
if (node.nodeName=="LI") {
node.onmouseover=function() {
this.className+=" over";
}
node.onmouseout=function() {
this.className=this.className.replace(" over", "");
}
}
}
}
}
window.onload=startList;
</script>
<style type="text/css">
<>
</style>
<table width="200" cellspacing="0" cellpadding="0" border="0" align="center">
<tr>
<td align="left">
<ul id="nav">
<?php
require('../Connections/lr.php');
mysql_select_db($database_lr, $lr);
$query = mysql_query("SELECT * FROM bigclass order by sort");
$j=0;
while($row=mysql_fetch_array($query))
{$j=$j+1;
$bigclassid=$row['bigclassid'];
$bigclassname_leftmenu=$row['bigclassname'];
if ($htmlname==1){
$bigclass_htmlname_leftmenu=$bigclassname_leftmenu;//大类名称
if (substr_count($bigclass_htmlname_leftmenu," ")>0){
$bigclass_htmlname_leftmenu= str_replace(" ","-",$bigclass_htmlname_leftmenu);
}
}
if ($htmlname==0){
$bigclass_htmlname_leftmenu=$bigclassid;
}
?>
<li><a href=""><?php echo $row['bigclassname']?></a>
<ul>
<?php
mysql_select_db($database_lr, $lr);
$query_small = mysql_query("SELECT * FROM smallclass where bigclassid='$bigclassid' order by sort");
while($rs=mysql_fetch_array($query_small))
{
$smallclassid_small_leftmenu=$rs['smallclassid'];
$smallclassname_small=$rs['smallclassname'];//小类名称
if ($htmlname==1){
$smallclass_htmlname=$smallclassname_small;
if (substr_count($smallclass_htmlname," ")>0){
$smallclass_htmlname= str_replace(" ","-",$smallclass_htmlname);
}
}
if ($htmlname==0){
