相信大家做网页的时候都会用到菜单。最近在CSDN上答题的时候，问动态菜单的还是比较多。这次就整3个动态菜单给同学们玩玩。方便刚入门的小鸟速度掌握。
正所谓天下文章大家抄，抄来抄去有提高.去百度一个JS+CSS菜单。CSS菜单
效果还算一般。我们把它抄袭下来 以后留用.
先来看看HTML

其中有定义的JS和CSS 不会不要紧。因为我们可以抄. OK开工。新建一个页面.讲这些代码复制进去 不解释.
仔细观察一下。 DIV的ID为MENU的貌似是父菜单。而下面那个DIV是加载上去的。那我们就从后台返回两个字符串用于页面绑定。一个也可以搞定。

其中有几个字段不需要。具体是干嘛的。下一篇会用到。。
采用拼接字符串。就像我经常CSDN解答的那样。
前台<%=str %>
后台public static string str=string.Empty;
建立个页面开整

效果 :
193行代码 其实我们可以优化的。
比如在一个FOR循环中拼接父节点和子节点的HTML。
也可以写一个递归的方法来用。这里用简单的DataTable.来拼接的html.其实代码不是最重要的。重要的是一种思想。
有兴趣的小鸟们可以练习练习。也可以去网上抄袭几个留着以后用.
下篇 来个实战。练练抄袭的功力.
