js实现无限级树形导航列表的相关文章

利用多叉树实现Ext JS中的无限级树形菜单（一种构建多级有序树形结构JSON的方法）

一.问题研究的背景和意义 目前在Web应用程序开发领域,Ext JS框架已经逐渐被广泛使用,它是富客户端开发中出类拔萃的框架之一.在Ext的UI控件中,树形控件无疑是最为常用的控件之一,它用来实现树形结构的菜单.TreeNode用来实现静态的树形菜单,AsyncTreeNode用来实现动态的异步加载树形菜单,后者最为常用,它通过接收服务器端返回来的JSON格式的数据,动态生成树形菜单节点.动态生成树有两种思路:一种是一次性生成全部树节点,另一种是逐级加载树节点(利用AJAX,每次点击节点时查询下

【JS 设计模式 】用组合模式来实现树形导航--代码结构思路分析（一）

树导航效果图: 组合模式的描述: 将对象组合成树形结构以表示"部分-整体"的层次结构,组合模式使得用户对单个对象和组合对象的使用具有一致性. 我们把部分用Leaf表示, 把整体用Composite表示.组合模式是有一定规律的,在实现树导航的情况下,Composite需要包含一个以上Leaf,也可以包含一个以上Leaf和一个以Composite,为什么说要包含一个以上的,如果Composite不包含任何子child的话那么它就是Leaf,Leaf表示是最后一层结节. 树形导航代码片段:
