浪奔，浪流，萬里濤濤江水永不休。如果在jq時代來實這個功能簡直有些噩夢了，但是自從前端思想發展到現在的以MVVM為主流的大背景下，來實現一個這樣繁雜的功能簡直不能容易太多。下麵就手把手帶您一步步撥開這個案例的層層迷霧。
實現步驟如下：
- api構建部門和員工信息介面，vuex全局存放部門list和員工list數據信息。
api：
export default { getEmployeeList () { return { returncode: 0, message: '', result: [ { id: 1, employeeName: '吳亦凡', departmentId: 44 }, { id: 2, employeeName: '鹿晗', departmentId: 45 }, { id: 3, employeeName: '孫紅雷', departmentId: 44 }, { id: 4, employeeName: '周傑倫', departmentId: 45 }, { id: 5, employeeName: '張國榮', departmentId: 45 }, { id: 6, employeeName: '陳百強', departmentId: 45 }, { id: 7, employeeName: '譚詠麟', departmentId: 41 }, { id: 8, employeeName: '谷村新司', departmentId: 45 }, { id: 9, employeeName: '中島美雪', departmentId: 46 }, { id: 10, employeeName: '周潤發', departmentId: 47 }, { id: 14, employeeName: '周慧敏', departmentId: 58 }, { id: 13, employeeName: '張學友', departmentId: 58 } ] } }, getDepartmentList () { return { returncode: 0, message: '', result: [ { id: 40, name: '研發一部', parentId: 37, sequence: 2 }, { id: 41, name: '研發二部', parentId: 37, sequence: 4 }, { id: 43, name: '市場', parentId: 0, sequence: 6 }, { id: 44, name: '銷售', parentId: 0, sequence: 4 }, { id: 45, name: '財務', parentId: 0, sequence: 5 }, { id: 46, name: '研發三部', parentId: 37, sequence: 1 }, { id: 47, name: '研發四部', parentId: 37, sequence: 3 }, { id: 37, name: '研發', parentId: 0, sequence: 5 }, { id: 58, name: '研發一部', parentId: 57, sequence: 1 }, { id: 59, name: '測試', parentId: 0, sequence: 5 }, { id: 60, name: '測試一部', parentId: 59, sequence: 1 }, { id: 61, name: '測試二部', parentId: 59, sequence: 2 }, { id: 62, name: '研發二部', parentId: 57, sequence: 2 } ] } } }
View Codestore:
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 }
- vue.$set為員工對象增加響應式屬性checked控制是否選中，methods中創建選中方法如下：
selectEmployee () { var self = this if (self.employee.checked === undefined) { this.$set(self.employee, 'checked', true) } else { self.employee.checked = !self.employee.checked } }
- computed計算屬性監控文本框輸入欄位searchKey的變化實現左側員工列表實時檢索功能。
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)) } }
- 構建組織結構樹的部門組件，部門下可能存在子部門和員工，所以組件內部再調用部門組件和員工組件，以達到迴圈遞歸的效果。
<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="添加整個部門成員"></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> - 結構樹之員工組件
<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> - 和上面員工的選中原理類似，控制部門節點的展開和合併也通過$set方法擴展一個響應式的expand屬性。
expandTree () { var self = this if (self.department.expand === undefined) { self.$set(self.department, 'expand', true) } else { self.department.expand = !self.department.expand } }
以上就是核心步驟的整體思路，歡迎討論。
