问题描述:JS处理树状结构的增删改查
最近在开发一个后台管理系统的权限管理模块,涉及到各种树状结构的数据处理逻辑,例如:增,删,改,查等;相比普通的数组结构数据,树状结构的处理就没有数组那么的直观,但是也没那么复杂,需要多一步——递归查找来对数据进行深度遍历操作,那么这里呢,博主也将开发过程中总结出来的方法分享给大家,一文带你吃透JS树装结构数据处理:
数据结构示例
解决方案:
1、新增节点
查找树装结构的指定节点,新增子节点,代码如下:
2、删除节点
查找树装结构的指定节点,删除节点,代码如下
3、修改节点
递归查找并修改某个节点的状态,代码如下:
4、查找节点
递归查找树形节点的某个节点,代码:
总结
本文介绍了js如何处理树装数据结构的增删改查,掌握以上函数,基本可以应对同样业务类型的数据处理,更多js处理数据问题方面的疑难杂症,推荐查看博主之前总结的文章,喜欢博主的朋友可以给博主点个关注,点关注,不迷路,博主带你上高速~~
