SPA项目开发之动态树+数据表格+分页

目录

一、左侧动态树形菜单

二、文章管理实现数据表格$分页

---

一、左侧动态树形菜单

思路：

1.要确定静态树形菜单的排版

2.要通过后台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

 LeftNav.vue：

<template>
	<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>

 二、文章管理实现数据表格$分页

        我们接下来实现点击文章管理绑定数据：

①创建组件

创建一个组件用来放置我们的文章管理的内容

Articles.vue

 ②定义绑定组件与路由的关系

index.js:

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import AppMain from '@/vue/AppMain'
import LeftNav from '@/vue/LeftNav'
import TopNav from '@/vue/TopNav'
import Login from '@/views/Login'
import Reg from '@/views/Reg'
import Articles from '@/vue/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
				}
      ]
    }
  ]
})

Articles.vue：

<template>
 <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>
template>
 
<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);
			}
		},
		created() {
			this.doSearch({});
		}
	}
script>
 
<style>
