LayUi 树形组件tree 实现懒加载模式，展开父节点时异步加载子节点数据

LayUi框架中树形组件tree官方还在持续完善中,目前最新版本为v2.5.5 官方树形组件目前还不支持懒加载方式,之前我修改一版是通过reload重载实例方法填充子节点数据方式,因为递归页面元素时存在效率问题,最终放弃升级. 本次重新star了官方最新tree.js源码,在其基础上扩展了子节点懒加载模式方法,data数据参数中增加了lazy: true,开启懒加载模式,需要配合spread事件使用. 部分源码修改截图: 调用例子: <!DOCTYPE html> <html> &

『左偏树 Leftist Tree』

新增一道例题左偏树 Leftist Tree 这是一个由堆(优先队列)推广而来的神奇数据结构,我们先来了解一下它. 简单的来说,左偏树可以实现一般堆的所有功能,如查询最值,删除堆顶元素,加入新元素等,时间复杂度也均相等,与其不同的是,左偏树还可以在$O(log_2n)$的时间之内实现两个堆的合并操作,这是一般的堆无法做到的. 特点当然,左偏树是一个树形数据结构,我们需要像线段树一样使用一个结构体来记录每一个节点上的若干信息,以便于进行查询,合并等操作,具体如下: 1.$val$值,代
