用dTree改造dedeeims产品目录
客户反映：点击产品目录其中一个分类后自动返回到一级分类，要求实现点击后产品信息更新但目录结构不变，其实就是局部刷新功能。
解决：
两个方案
１.AJAX技术实现网页无闪自动局部刷新
２.直接用JS实现
下面就介绍用dTree来做
dTree优点有（作者的网站 http://destroydrop.com/javascripts/tree/）
1.无限级分类
2.可用于内嵌框架
3.自动记录状态(跳转页面后目录仍然保持最后状态不会还原成全部折叠)
4.可在一个页面上存在多个DTREE
5.支持所有常用浏览器
√Internet Explorer 5+
√Netscape 6+
√Opera 7+
√Mozilla FireFox
6.符合XHTML 1.0
7.可替换图片
修改cattree.lib.php标签(加粗部分为更改过)，
if(!defined('DEDEINC')) exit("Request Error!");
function lib_cattree(&$ctag,&$refObj)
{
global $dsql,$cfg_df_lang;
//属性处理
//属性 showall 在空或不存在时，强制用产品模型id；如果是 yes 刚显示整个语言区栏目树；为其它数字则是这个数字的模型的id
//typeid 指定顶级树 id ，指定后，前一个属性将无效
$attlist="showall|,catid|0";
FillAttsDefault($ctag->CAttribute->Items,$attlist);
extract($ctag->CAttribute->Items, EXTR_SKIP);

用你的这个方法成功了。。。用动态访问 鼠标点击栏目的下面的背景色包括点开的子类不会错误。。但如果我生成静态那就不行了，虽然还能调出来，但点击某一个栏目却打开的是其他的栏目。。这是为何呀？你知道吗？
