大家好！先上图看看本次案例的整体效果。

**浪奔，浪流，万里涛涛江水永不休。如果在jq时代来实这个功能简直有些噩梦了，但是自从前端思想发展到现在的以MVVM为主流的大背景下，来实现一个这样繁杂的功能简直不能容易太多。下面就手把手带您一步步拨开这个案例的层层迷雾。**

实现步骤如下：

1. api构建部门和员工信息接口，vuex全局存放部门list和员工list数据信息。

api：

export default { getEmployeeList () {  return {   returncode: 0,   message: '',   result: [    {     id: 1,     employeeName: '吴亦凡',     departmentId: 44    },    {     id: 2,     employeeName: '鹿晗',     departmentId: 45    },    {     id: 3,     employeeName: '孙红雷',     departmentId: 44    },    {     id: 4,     employeeName: '周杰伦',     departmentId: 45    },    {     id: 5,     employeeName: '张国荣',     departmentId: 45    },    {     id: 6,     employeeName: '陈百强',     departmentId: 45    },    {     id: 7,     employeeName: '谭咏麟',     departmentId: 41    },    {     id: 8,     employeeName: '谷村新司',     departmentId: 45    },    {     id: 9,     employeeName: '中岛美雪',     departmentId: 46    },    {     id: 10,     employeeName: '周润发',     departmentId: 47    },    {     id: 14,     employeeName: '周慧敏',     departmentId: 58    },    {     id: 13,     employeeName: '张学友',     departmentId: 58    }   ]  } }, getDepartmentList () {  return {   returncode: 0,   message: '',   result: [    {     id: 40,     name: '研发一部',     parentId: 37,     sequence: 2    },    {     id: 41,     name: '研发二部',     parentId: 37,     sequence: 4    },    {     id: 43,     name: '市场',     parentId: 0,     sequence: 6    },    {     id: 44,     name: '销售',     parentId: 0,     sequence: 4    },    {     id: 45,     name: '财务',     parentId: 0,     sequence: 5    },    {     id: 46,     name: '研发三部',     parentId: 37,     sequence: 1    },    {     id: 47,     name: '研发四部',     parentId: 37,     sequence: 3    },    {     id: 37,     name: '研发',     parentId: 0,     sequence: 5    },    {     id: 58,     name: '研发一部',     parentId: 57,     sequence: 1    },    {     id: 59,     name: '测试',     parentId: 0,     sequence: 5    },    {     id: 60,     name: '测试一部',     parentId: 59,     sequence: 1    },    {     id: 61,     name: '测试二部',     parentId: 59,     sequence: 2    },    {     id: 62,     name: '研发二部',     parentId: 57,     sequence: 2    }   ]  } }}

store:

import dataApi from '@/api/data.api.js'const state = { employeeList: [], departmentList: []}const getters = { employeeList: state => state.employeeList, departmentList: state => state.departmentList}const mutations = { SetEmployeeList (state, { employeeList }) {  state.employeeList = employeeList }, SetDepartmentList (state, { departmentList }) {  state.departmentList = departmentList }}const actions = { getEmployeeList ({ commit }) {  let employeeResult = dataApi.getEmployeeList()  if (employeeResult.returncode === 0) {   commit('SetEmployeeList', { employeeList: employeeResult.result })  } }, getDepartmentList ({ commit }) {  let departmentResult = dataApi.getDepartmentList()  if (departmentResult.returncode === 0) {   commit('SetDepartmentList', { departmentList: departmentResult.result })  } }}export default { state, getters, mutations, actions, namespaced: true}

2. vue.$set为员工对象增加响应式属性checked控制是否选中，methods中创建选中方法如下：

selectEmployee () {   var self = this   if (self.employee.checked === undefined) {    this.$set(self.employee, 'checked', true)   } else {    self.employee.checked = !self.employee.checked   }  }

3. computed计算属性监控文本框输入字段searchKey的变化实现左侧员工列表实时检索功能。

searchEmployeeList () {   var self = this   if (self.searchKey.trim() === '') {    console.log(self.employeeList)    return self.employeeList.filter(item => item.checked === undefined || !item.checked)   } else {    return self.employeeList.filter(item => (item.employeeName.indexOf(self.searchKey.trim()) !== -1) && (item.checked === undefined || !item.checked))   }  }

4. 构建组织结构树的部门组件，部门下可能存在子部门和员工，所以组件内部再调用部门组件和员工组件，以达到循环递归的效果。

5. 结构树之员工组件

6. 和上面员工的选中原理类似，控制部门节点的展开和合并也通过$set方法扩展一个响应式的expand属性。

expandTree () {   var self = this   if (self.department.expand === undefined) {    self.$set(self.department, 'expand', true)   } else {    self.department.expand = !self.department.expand   }  }
