描述 TreeTo 是一个 JavaScript 对于树形结构的转换以及操作查询的工具库

GitHub:https://github.com/nuts-cake/treeTo npm:https://www.npmjs.com/package/treeto

$ npm install treeto

$ yarn add treeto

内容

toTreeFnNoIdp 无 id/pId 树形数据-平行数据
toTreeFnHasIdp 又 id/Pid 树形数据-平行数据
treeCreateKey 树形数据-内部-创造-新参数
treeDeleteKey 树形数据-内部-删除-无用参数
queryAllPid 树形数据查询-查找全部父级节点 id
queryOneNode 树形数据查询-查找单条节点
queryPidLine 树形数据查询-查出整条祖先链 id

版本预告

不同情况下:平行数据->树形数据
更多常用查询功能
优化代码

toTreeFnNoIdp

使用递归将平行数据结构转换成树形数据结构(无 id 情况下)

# import { toTreeFnNoIdp} from 'treeto'
 let list = [
    {
      college: "梦想的学院",
      grade: "一年级",
      clazz: "1班",

    {
      college: "嗷嗷叫学院",
      grade: "二年级",
      clazz: "1班",
      id: "xxx",
    },
    {
      college: "嗷嗷叫学院",
      grade: "一年级",

    },
  ];
  const winCondition = ["college", "grade", "clazz"];
  const newList = toTreeFnNoIdp(list,winCondition);

output log:

queryAllPid

查找全部父级节点 id ( 分别找出[xx,xx]的单层父节点 )

# import { queryAllPid } from 'treeto'
const pidList = queryAllPid(treeData,[131,1231])

output log:

 [131,1231,123,13]

queryOneNode(treeData,131)

查找单条节点

# import { queryOneNode } from 'treeto'
const node = queryOneNode(treeData,131)

output log:

 {"id":131,"pid":13,"name":"子公司2-1"}

queryPidLine (treeData,131)

查出整条祖先链-id

# import { queryPidLine } from 'treeto'
const node = queryPidLine(treeData,131)
