【Vue.js实战案例】- Vue.js递归组件实现组织架构树和选人功能


         大家好!先上图看看本次案例的整体效果。

 

 完整版实战课程附demoVue.js递归组件实现多层级菜单结构树+仿QQ建群选人功能

 

       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
            }
          ]
        }
      }
    }
    View Code

    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。
    <template>
      <li @click.stop="expandTree()">
        <a :class="lvl|level">
          <span class="expand-tree-icon">
            <i class="fa fa-caret-right" :class="{'active':department.expand}"></i>
          </span>
          <span>
            <i class="lcfont lc-department-o"></i>
          </span>
          <span class="title">
            <span>{{department.name}}</span>
            <span class="title-desc">({{allChildEmployeeList.length}}人 )</span>
            <i class="lcfont lc-add" @click.stop="selectDepartmentEmployees()" title="添加整个部门成员"></i>
          </span>
        </a>
        <ul v-show="department.expand">
          <child-employee
            v-for="(employee,index) in childEmployeeList"
            :employee="employee"
            :lvl="lvl+1"
            :key="index"
          ></child-employee>
          <child-department
            v-for="(department,index) in childDepartmentList"
            :department="department"
            :employeeList="employeeList"
            :departmentList="departmentList"
            :lvl="lvl+1"
            :key="index"
          ></child-department>
        </ul>
      </li>
    </template>

     

  5. 结构树之员工组件
    <template>
      <li v-on:click.stop="selectEmployee()">
        <a class="member-item" v-bind:class="lvl|level" href="javascript:;">
          <div class="lc-avatar flex-se1" name="true" size="30">
            <div class="lc-avatar-30" :title="employee.employeeName">
              <span class="lc-avatar-def" style="background-color: rgb(112, 118, 142);">
                <div>{{employee.employeeName}}</div>
              </span>
              <div class="lc-avatar-name">{{employee.employeeName}}</div>
            </div>
          </div>
          <i class="lcfont" v-bind:class="{'lc-check':employee.checked}"></i>
        </a>
      </li>
    </template>

     

  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
          }
        }
