table-tree 表格树、树形数据处理、数据转树形数据

前言

公司想搞个表格树的展示页面，看着element有个表格树，还以为可以用。

用出来只用表格没有树，研究半天没研究个所以然，只能从新找个

npm里找到一个：vue-table-with-tree-grid

正文

element的坑

element：http://element-cn.eleme.io/#/zh-CN/component/table

 

 

然后一模一样的代码用在项目中，标点符合都没改：

 

 

 

emmmmmmmm。。。。最前面的箭头不见了。。。换了好几个系统试了一下。居然都没有。。

毫不犹豫投入了vue-table-with-tree-grid的怀抱

vue-table-with-tree-grid

npm中它的地址：https://www.npmjs.com/package/vue-table-with-tree-grid

安装

npm i vue-table-with-tree-grid -S
Or use yarn:

yarn add vue-table-with-tree-grid

 

导入

import Vue from 'vue'
import ZkTable from 'vue-table-with-tree-grid'
 
Vue.use(ZkTable)
Or

import Vue from 'vue'
import ZkTable from 'vue-table-with-tree-grid'
 
Vue.component(ZkTable.name, ZkTable)

　　

示例：

显示效果：

 

 

 

递归处理树形数据

用树形数据的时候经常会需要为树形数据修改值，增加值之类的

示例

respose.data // 我是树形数据

//遍历

for (let i = 0, len = respose.data.length; i < len; i++) {

readTree(respose.data[i])

}

 

const readTree = function(node) {

node.flag === '0' ? node.flag1 = '我是flag1的值1' : node.flag1 = '我是flag1的值2'

node.label = 我是label 的新值

if (node.children && node.children.length > 0) {

for (let i = 0, len = node.children.length; i < len; i++) {

readTree(node.children[i])

}

}

}

 

原始数据转树形数据

//data为原始数据，root最大的根节点，idTxt为本身标识, pidTxt为父级标识, pushTxt为子级标识

getTree(data, root, idTxt, pidTxt, pushTxt) {

// 递归方法

function getNode(id) {

var node = []

for (var i = 0; i < data.length; i++) {

if (datai === id) {

datai = getNode(datai)

node.push(data[i])

}

}

if (node.length === 0) {

return

} else {

return node

}

}

// 使用根节点

return getNode(root)

}
//原始数据：

{"id":1,"pId":0,"name":"父节点1 - 展开","open":true},
  {"id":11,"pId":1,"name":"父节点11 - 折叠"},
  {"id":12,"pId":1,"name":"父节点12 - 折叠"},
  {"id":13,"pId":1,"name":"父节点13 - 没有子节点"},
  {"id":2,"pId":0,"name":"父节点2 - 折叠"},
  {"id":21,"pId":2,"name":"父节点21 - 展开","open":true},
  {"id":22,"pId":2,"name":"父节点22 - 折叠"},
  {"id":23,"pId":2,"name":"父节点23 - 折叠"},
  {"id":3,"pId":0,"name":"父节点3 - 没有子节点"}
`

`

//处理后的数据

[
  {
    "id": 1,
    "pId": 0,
    "name": "父节点1 - 展开",
    "open": true,
    "children": [
      {
        "id": 11,
        "pId": 1,
        "name": "父节点11 - 折叠"
      },
      {
        "id": 12,
        "pId": 1,
        "name": "父节点12 - 折叠"
      },
      {
        "id": 13,
        "pId": 1,
        "name": "父节点13 - 没有子节点"
      }
    ]
  },
  {
    "id": 2,
    "pId": 0,
    "name": "父节点2 - 折叠",
    "children": [
      {
        "id": 21,
        "pId": 2,
        "name": "父节点21 - 展开",
        "open": true
      },
      {
        "id": 22,
        "pId": 2,
        "name": "父节点22 - 折叠"
      },
      {
        "id": 23,
        "pId": 2,
        "name": "父节点23 - 折叠"
      }
    ]
  },
  {
    "id": 3,
    "pId": 0,
    "name": "父节点3 - 没有子节点"
  }
]

完结 ，撒花
