  1.   

     XML+ JS创建树形菜单 http://www.blueidea.com/tech/web/2004/1642.asp
      

  2.   

    简单说明:思路:
    从数据岛menuXML中读取数据,从树的根节点开始分析树,
    利用 hasChildNodes() [方法:是否含有子节点 ] 判断当前
    节点是否有子节点,如果有子节点继续向下分析 childNodes
    [对象:子节点对象集合] ,否则返回当前分析结果(树结点对象)。主要的函数: 
    createTree(thisn /*树结点*/ , sd/*树深度*/)
