很好很强大,,帮你贴出来dh20156 发表于：2007-11-28 08:31:28 楼主
dhCode集合，包含了dh20156风之石在平时写过的一些比较有价值的WEB应用，希望可以为大家的WEB开发提供一定的参考！ dhCode集合包含了以下部分内容：
1）dhATV，dhAjaxTreeView以及无限节点前后台实现方式；
2）dhcombobox，可输入、匹配的下拉选择框；
3）dhdatagrid，数据表格控件；
4）dhkeyboard，WEB软键盘，包含五笔、拼音、英文输入法；
5）dhLayer，提供IE及FF下都可以盖住FLASH，SELECT等控件的内容容器；
6）dhtabstrip，标签页控件，内置windows经典，XP及126邮箱等多种皮肤；
7）dhxmltreeview，比较早前写的一个通过加载XML文档生成的树；
8）dhadshow，广告轮显；
9）dhScroll系列，几种无缝滚动的实现；下载地址:http://download.csdn.net/source/295810
