VUE使用vue-tree-color组件实现组织架构图并可以动态更新数据的效果

# use npm
npm install vue-tree-color

npm install --save-dev less less-loader

import Vue from 'vue'
import Vue2OrgTree from 'vue-tree-color'
Vue.use(Vue2OrgTree)

<vue2-org-tree :data="data"/>
...
 datas:{
        id:0,
        label:'一级',
        children:[
          {
            id:11,
            label:'二级1'
          }
        ]
      }

# 只需要加上 horizontal 即可
<vue2-org-tree :data="datas" :horizontal="true" />

 <vue2-org-tree :data="data" :horizontal="true" collapsable @on-expand="onExpand" />
...
methods: {
    collapse(list) {
        var _this = this
        list.forEach(function(child) {
            if (child.expand) {
                child.expand = false
            }
            child.children && _this.collapse(child.children)
        })
    },
    onExpand(e, data) {
        if ('expand' in data) {
            data.expand = !data.expand
            if (!data.expand && data.children) {
                this.collapse(data.children)
            }
        } else {
            this.$set(data, 'expand', true)
        }
    }
}

<vue2-org-tree :data="data" :horizontal="true" collapsable @on-expand="onExpand" @on-node-click="onNodeHandle" />
...
onNodeHandle(e, data) {
    // e是节点数据
    console.log(e)
    // data是渲染在节点上的数据
    console.log(data)
