ElementUI之动态数据+数据表格+分页
- 一、准备工作
-
- 1. 修改dev.env.js的配置
- 2. 修改mockjs之前的假数据
- 3. 测试画面展示
- 二、将菜单栏的静态数据改为动态数据
-
- 1. 新增api/action.js的接口
- 2. 菜单栏（LeftNav.vue）代码修改
- 3. 新增BookList.vue和AddBook.vue
- 4. 修改AppMain中的内容
- 5. 新增BookList.vue和AddBook.vue的路由
- 三、书籍数据显示
一、准备工作
1. 修改dev.env.js的配置
在config/dev.env.js将MOCK的值修改为false
'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')
module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
MOCK: 'false'
})
2. 修改mockjs之前的假数据
doSubmit: function () {
let params = {
username: this.username,
password: this.password
};
console.log(params);
let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
this.axios.post(url, params).then(response => {
console.log(response);
if (response.data.success) {
this.$message({
message: response.data.msg,
type: 'success'
})
this.$router.push({path:'/appMain'});
} else {
this.$message({
message: response.data.msg,
type: 'error'
})
}
}).catch(error => {
console.log(error);
});
3. 测试画面展示
二、将菜单栏的静态数据改为动态数据
1. 新增api/action.js的接口
/**
* 对后台请求的地址的封装，URL格式如下：
* 模块名_实体名_操作
*/
export default {
'SERVER': 'http://localhost:8080/ssm', //服务器
'SYSTEM_USER_DOLOGIN': '/user/userLogin', //用户登陆
'SYSTEM_MENU': '/module/queryRootNode', //系统菜单
'BOOK_LIST': '/book/queryBookPager', //数据查询
'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用
return this.SERVER + this[k];
}
}
2. 菜单栏（LeftNav.vue）代码修改
<template>
<el-menu router :default-active="$route.path" default-active="2" class="el-menu-vertical-demo"
background-color="#334157" text-color="#fff" active-text-color="#ffd04b" :collapse="collapsed">
<!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->
<div class="logobox">
<img class="logoimg" src="../assets/img/logo.png" alt="">
</div>
<el-submenu v-for="m in menus" :index="'index_' + m.id" :key="'key_' + m.id">
<template slot="title">
<i :class="m.icon"></i>
<span>{{m.text}}</span>
</template>
<el-menu-item v-for="m2 in m.modules" :index="m2.url" :key="'key_' + m2.id">
<i :class="m2.icon"></i>
<span>{{m2.text}}</span>
</el-menu-item>
</el-submenu>
</el-menu>
</template>
<script>
export default {
data() {
return {
collapsed: false,
menus: []
}
},
created() {
this.$root.Bus.$on('doCollapsed', v => {
//v指的是topNav传递过来的this.collapsed
this.collapsed = v;
});
//通过axios获取后端数据
let url = this.axios.urls.SYSTEM_MENU;
this.axios.get(url, {}).then(response => {
console.log(response);
this.menus = response.data.rows;
}).catch(error => {
});
}
}
</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>
3. 新增BookList.vue和AddBook.vue
- BookList.vue
<template>
<div>书籍管理</div>
</template>
<script>
}
</script>`在这里插入代码片`
<style scoped>
</style>
- AddBook.vue
<template>
<div>书籍新增</div>
</template>
<script>
</script>
<style scoped>
</style>
4. 修改AppMain中的内容
在AppMain.vue中添加router-view
<el-main class="main-center">
<router-view></router-view>
</el-main>
5. 新增BookList.vue和AddBook.vue的路由
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Login from '@/views/Login'
import Register from '@/views/Register'
import AppMain from '@/components/AppMain'
import LeftNav from '@/components/LeftNav'
import TopNav from '@/components/TopNav'
import AddBook from '@/views/book/AddBook'
import BookList from '@/views/book/BookList'
Vue.use(Router)
export default new Router({
routes: [{
path: '/',
name: 'Login',
component: Login
},
{
path: '/HelloWorld',
name: 'HelloWorld',
component: HelloWorld
},
{
path: '/Register',
name: 'Register',
component: Register
},
{
path: '/appMain',
name: 'AppMain',
component: AppMain,
children: [{
path: '/TopNav',
name: 'TopNav',
component: TopNav
}, {
path: '/leftNav',
name: 'LeftNav',
component: LeftNav
},
{
path: '/book/AddBook',
name: 'AddBook',
component: AddBook
},
{
path: '/book/BookList',
name: 'BookList',
component: BookList
}
]
}
]
})
三、书籍数据显示
BookList.vue代码展示：
<template>
<div style="padding: 20px">
<!--搜索框-->
<el-form :inline="true" class="form-search">
<el-form-item label="书本名称">
<el-input v-model="bookname" placeholder="请输入书本名称"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" icon="el-icon-search" @click="onSubmit()">查询</el-button>
</el-form-item>
</el-form>
<!-- 数据表格 -->
<el-table :data="tableData" style="width: 100%">
<el-table-column prop="id" label="书籍编号" width="180"></el-table-column>
<el-table-column prop="bookname" label="书籍名称" width="180"></el-table-column>
<el-table-column prop="price" label="价格" width="180"></el-table-column>
<el-table-column prop="booktype" label="书籍类别"></el-table-column>
</el-table>
<!-- 分页条 -->
<el-pagination background
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page="page"
:page-sizes="[10, 20, 30, 40]"
:page-size="rows"
layout="total, sizes, prev, pager, next, jumper"
:total="total">
</el-pagination>
</div>
</template>
<script>
export default {
name: "BookList",
data() {
return {
bookname: '',
tableData: [],
page: 1,
rows: 10,
total: 0
}
},
created() {
let params = {
bookname: this.bookname
}
this.query(params);
},
methods: {
query(params){
//搜索方法
let url = this.axios.urls.BOOK_LIST;
this.axios.get(url, {params: params}).then(resp => {
this.tableData = resp.data.rows;
this.total = resp.data.total;
}).catch(err=>{
});
},
onSubmit() {
let params = {
bookname: this.bookname
}
this.query(params);
},
handleSizeChange(r) {
let params = {
bookname: this.bookname,
rows: r
}
this.query(params)
},
handleCurrentChange(p) {
let params = {
bookname: this.bookname,
page: p
}
this.query(params)
}
}
}
</script>
<style scoped>
</style>
