先上图来一波 支持无限层级,支持新增子级时自动打开父级,支持编辑时自动打开父级,执行操作时自带动画效果,支持初始化时设置全部打开或者关闭,支持一键展开与关闭丝滑般的无延迟 由于基于el-table扩展的,所以当然能够使用el-table的所有功能 下面上代码: 1,核心JS,格式化数据源 'use strict' import Vue from 'vue' export default function treeToArray(data, expandAll, parent = null, le

上一篇介绍了DataTable,这一篇在DT的基础之上再使用jquery的一款插件:treegrid,官网地址:http://maxazan.github.io/jquery-treegrid/ 一.使用treegrid,需要以下支持 jquery.min.js+jquery.treegrid.min.js 二.后端提供树状列表格式的集合数据,借助前端的DT的配置控制,来在页面上输出满足treegrid格式要求的html 前台: @using Model @{ Layout = null; Us

一.TreeView介绍 TreeView组件是一个树状结构和表格的结合体.第一列是树状结构,后几列是列表.每一行表示一个item,树的item可以分级,每个item有子item,名称对应text标签.每一行的值用values元组里的值表示. item有5个标签,分别是:text,image,values,open,tags. 二.参数说明 1.TreeView参数: 参数 作用 columns   值是一个列表.列表里每个元素代表一个列标识符的名称.列表的长度为列的长度. displaycol

在日常项目开发中,树状下拉框的需求还是比较常见的,但是element并没有这种组件以供使用.在这里,小编就基于element如何封装一个树状下拉框做个详细的介绍. 通过这篇文章,你可以了解学习到一个树状下拉框组件是如何一步一步封装成功的. 话不多说,先看效果图: 封装组件 该组件主要基于element的select组件.tree组件及input组件进行二次封装的.组件布局 首先我们需要基于这几个组件对我们的组件进行布局,话不多说直接上代码: <template> <el-select r

树状结构Java模型.层级关系Java模型.上下级关系Java模型与html页面展示 一.业务原型:公司的组织结构.传销关系网 二.数据库模型 很简单,创建 id 与 pid 关系即可.(pid:parent_id) 三.Java模型 (我们把这张网撒在html的一张表里.其实用ul来展示会简单N多,自己思考为什么LZ会选择放在表里) private class Table {        private Long id; // 当前对象的id         private int x; /

D. Iahub and Xors   Iahub does not like background stories, so he'll tell you exactly what this problem asks you for. You are given a matrix a with n rows and n columns. Initially, all values of the matrix are zeros. Both rows and columns are 1-based

大家都知道使用NPOI导出Excel格式数据 很简单,网上一搜,到处都有示例代码. 因为工作的关系,经常会有处理各种数据库数据的场景,其中处理Excel 数据导出,以备客户人员确认数据,场景很常见. 一个系统开发出来,系统要运行起来,很多数据要初始化,这个时候也是需要客户提供各种业务的基础数据.客户提供的数据中,其中除了word.pdf,最常见的就是Excel. 废话不多说,直接上图上代码: 如图, 左侧三列,作为 一个系统 所有菜单的树状结构. 其他列 以用户的信息(如用户名.登录名) 作为表

树状数组求逆序对   转载http://www.cnblogs.com/shenshuyang/archive/2012/07/14/2591859.html 转载: 树状数组,具体的说是 离散化+树状数组.这也是学习树状数组的第一题. 算法的大体流程就是: 1.先对输入的数组离散化,使得各个元素比较接近,而不是离散的, 2.接着,运用树状数组的标准操作来累计数组的逆序数. 算法详细解释: 1.解释为什么要有离散的这么一个过程? 刚开始以为999.999.999这么一个数字,对于int存储类型来
