SPA项目开发之动态树+数据表格+分页
目录
一、树形菜单功能实现
思路：
1.要确定静态树形菜单的排版
2.要获取树形节点的数据 this.axious.post
3.通过拿到的数据，渲染树形节点
v-for 渲染节点
定义渲染节点的变量
注意：今天实现和数据库的数据交互，所以要将前端的项目运行起来
用用户表中的用户信息进行登录
LeftNav.vue
- <el-menu router :default-active="$route.path" class="el-menu-vertical-demo" background-color="#334157"
- text-color="#fff" active-text-color="#ffd04b" :collapse="collapsed" >
- <div class="logobox">
- <img class="logoimg" src="../assets/img/logo.png" alt="">
- div>
- <el-submenu v-for="m in menus" :key="'id_'+m.treeNodeId">
- <template slot="title">
- <i :class="m.icon">i>
- <span >{{m.treeNodeName}}span>
- template>
- <el-menu-item v-for="m2 in m.children" :key="'id_'+m2.treeNodeId" :index="m2.url">
- <i :class="m2.icon">i>
- <span >{{m2.treeNodeName}}span>
- el-menu-item>
- el-submenu>
- el-menu>
- template>
- <script>
- export default {
- data(){
- return {
- collapsed:false,
- menus:[]
- }
- },
- created(){
- this.$root.Bus.$on("collapsed-side", (v)=>{
- this.collapsed= v ;
- });
- //向后台拿树形节点的数据
- let url = this.axios.urls.SYSTEM_MENU_TREE;
- this.axios.post(url, {})
- .then(resp => { //代表成功 箭头函数 jdk8的语法
- console.log(resp);
- //debugger
- this.menus = resp.data.result;
- }).catch(function() { //代表失败
- });
- }
- }
- script>
- <style>
- .el-menu-vertical-demo:not(.el-menu--collapse) {
- width: 240px;
- min-height: 400px;
- }
- .el-menu-vertical-demo:not(.el-menu--collapse) {
- border: none;
- text-align: left;
- }
- .el-menu-item-group__title {
- padding: 0px;
- }
- .el-menu-bg {
- background-color: #1f2d3d !important;
- }
- .el-menu {
- border: none;
- }
- .logobox {
- height: 40px;
- line-height: 40px;
- color: #9d9d9d;
- font-size: 20px;
- text-align: center;
- padding: 20px 0px;
- }
- .logoimg {
- height: 40px;
- }
- style>
index.js
- import Vue from 'vue'
- import Router from 'vue-router'
- import HelloWorld from '@/components/HelloWorld'
- import AppMain from '@/components/AppMain'
- import LeftNav from '@/components/LeftNav'
- import TopNav from '@/components/TopNav'
- import Login from '@/views/Login'
- import Reg from '@/views/Reg'
- import Articles from '@/views/sys/Articles'
- Vue.use(Router)
- export default new Router({
- routes: [{
- path: '/',
- name: 'Login',
- component: Login
- },
- {
- path: '/Login',
- name: 'Login',
- component: Login
- },
- {
- path: '/Reg',
- name: 'Reg',
- component: Reg
- },
- {
- path: '/AppMain',
- name: 'AppMain',
- component: AppMain,
- children: [{
- path: '/LeftNav',
- name: 'LeftNav',
- component: LeftNav
- },
- {
- path: '/TopNav',
- name: 'TopNav',
- component: TopNav
- }
- ,{
- path: '/sys/Articles',
- name: 'Articles',
- component: Articles
- }
- ]
- }
- ]
- })
二、书籍列表查询
Articles.vue
- <div>
- <el-form :inline="true" :model="formInline" class="user-search">
- <el-form-item label="搜索：">
- <el-input size="small" v-model="formInline.title" placeholder="输入文章标题">el-input>
- el-form-item>
- <el-form-item>
- <el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索el-button>
- el-form-item>
- el-form>
- <el-table size="small" :data="listData" element-loading-text="拼命加载中" style="width: 100%;">
- <el-table-column align="center" type="selection" min-width="1">
- el-table-column>
- <el-table-column sortable prop="id" label="文章ID" min-width="1">
- el-table-column>
- <el-table-column sortable prop="title" label="文章标题" min-width="3">
- el-table-column>
- <el-table-column sortable prop="body" label="文章内容" min-width="5">
- el-table-column>
- el-table>
- <el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
- :current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="100" layout="total, sizes, prev, pager, next, jumper"
- :total="total">
- el-pagination>
- div>
- <script>
- export default {
- data() {
- return {
- listData: [],
- formInline: {
- page: 1,
- rows: 10,
- title: ''
- },
- total: 0
- };
- },
- methods: {
- handleSizeChange(rows) {
- this.formInline.page = 1;
- this.formInline.rows = rows;
- this.search();
- },
- handleCurrentChange(page) {
- this.formInline.page = page;
- this.search();
- },
- doSearch(params) {
- let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
- // let url = 'http://localhost:8080/T216_SSH/vue/userAction_login.action';
- this.axios.post(url, params).then((response) => {
- console.log(response);
- this.listData = response.data.result;
- this.total = response.data.pageBean.total;
- }).catch(function(error) {
- console.log(error);
- });
- },
- search(){
- this.doSearch(this.formInline);//按照条件进行查询
- }
- },
- created() {
- this.doSearch({});
- }
- }
- script>
- <style>
- style>
要实现点击文章管理跳转到Articles.vue的组件上，一定要记得写锚点
总结文章的查询功能的实现
1.el_table 列表组件
2.利用axious调用后台的文章查询接口 -->created
3.el-pagination 列表组件
size-change 页面大小改变调用的事件
current-change 页码改变调用的事件
4.优化 将后台的文章查询接口的代码进行封装，便于复用
5.el-form查询的筛选条件 传参
效果：
输入之
不输
