Element-Ul是饿了么前端团队推出的一款基于Vue.js 2.0 的桌面端UI框架,一套为开发者、设计师和产品经理准备的基于 Vue 2.0 的桌面端组件库,手机端有对应框架是Mint UI 。
中文文档:http://element-cn.eleme.io/#/zh-CN github地址:https://github.com/ElemeFE/element
端开发框架和环境都是需要 Node.js ,先安装node.js开发环境,vue的运行是要依赖于node的npm的管理工具来实现,下载https://nodejs.org/en/,安装完成之后,打开cmd开始输入命令。(我用的是win10系统,所以需要管理员权限,右键点击以管理员身份运行cmd),不然会出现很多报错。
下载好node之后,以管理员身份打开cmd管理工具,,输入 node -v ,回车,查看node版本号,出现版本号则说明安装成功。
输入命令: node -v
由于npm是国外的,使用起来比较慢,我们这里使用淘宝的cnpm镜像来安装vue. 淘宝的cnpm命令管理工具可以代替默认的npm管理工具。
输入命令:npm install -g cnpm --registry=https://registry.npm.taobao.org
淘宝镜像安装成功之后,我们就可以全局vue-cli脚手架,输入命令:cnpm install --global vue-cli 回车;验证是否安装成功,在命令输入vue,出来vue的信息,及说明安装成功;
输入命令:cnpm install --global vue-cli
我这里是在d盘里面新建一个项目,先用d:
的命令,回车键进入d盘;回车键默认创建项目信息。
vue init webpack itemname
出现这样的提示,初始化成功
运行初始化demo,输入命令npm run dev;运行一下初始后的demo,弹出访问地址,如果没有问题则进行安装elementUI;准备好好之后,开始引入饿了么elementUI组件。
npm i element-ui -S
快捷键ctrl+c,终止批处理操 作吗(Y/N),在输入命令npm i element-ui -S
注意:安装过程中出现这样的bug的时候,需要解决
解决办法:尝试 删除项目中的 package-lock.json 文件 和 node_modules 文件夹,然后再尝试 npm install.
成功安装组件显示如下
- <template>

npm run dev 运行,浏览器显示如下,实现了一个简单的时间选择器
点击按钮的时候,元素会呈现一个出现和隐藏的动画功能。

导航菜单效果如下所示
## 导航栏跳转路由
### 1:components 新建页面
### 2:打开app.vue写代码
- <template>
- <div>
- <el-col :span="2">
- <el-menu
- :default-active="this.$route.path"
- router mode="horizontal"
- class="el-menu-vertical-demo"

- <template slot="title">
- <i class="el-icon-s-platform"></i>
- <span> {{ item.navItem }}</span>
- </template>
-

- </el-col>
-
- <router-view class="menu-right"/>
-
- </div>
- </template>
- <script>
- export default {
- data() {
- return {
- navList:[
- {name:'/components/ServiceHall',navItem:'服务大厅'},
- {name:'/components/Management',navItem:'权限管理'},
- {name:'/components/User',navItem:'用户管理'},
- {name:'/components/Personnel',navItem:'人员数据'},
- {name:'/components/Alarm',navItem:'报警中心'},
- ] }
- },
- methods: {
- handleOpen(key, keyPath) {
- console.log(key, keyPath);
- },
- handleClose(key, keyPath) {
- console.log(key, keyPath);
- }
- }
- }
- </script>
-
- <style>
- .menu-right{
- margin-left:200px;
- }
-
- </style>
- import Vue from 'vue'
- import Router from 'vue-router'
- import HelloWorld from '@/components/HelloWorld'
- import ServiceHall from '@/components/ServiceHall'
- import Management from '@/components/Management'
- import User from '@/components/User'
- import Personnel from '@/components/Personnel'
- import Alarm from '@/components/Alarm'
-
- Vue.use(Router)
-
- export default new Router({
- routes: [
- {
- path: '/',
- name: 'HelloWorld',
- component: HelloWorld
- },
- {
- path: '/components/ServiceHall',
- name: 'ServiceHall',
- component: ServiceHall

- component: Management
- },
- {
- path: '/components/User',
- name: 'User',
- component: User
- },{
- path: '/components/Personnel',
- name: 'Personnel',
- component: Personnel
- },{
- path: '/components/Alarm',
- name: 'Alarm',
- component: Alarm
- }
- ]
- })
- <template>
- <div>
- 我是权限管理页面
- </div>
- </template>
- <script>
- </script>
- <style>
- </style>
npm install axios --save
import axios from 'axios'
自己写了一个json数据,放在服务器上,现在要通过vue项目调用数据 http://www.intmote.com/test.json
在config/index.js 里面找到proxyTable :{} ,然后在里面加入以下代码
proxyTable: { '/api': { target: 'http://www.intmote.com',//设置你调用的接口域名和端口号 别忘了加http changeOrigin: true,//允许跨域 pathRewrite: { '^/api': '' //这个是定义要访问的路径,名字随便写 } } },
methods: { getData() { axios.get('/api/test.json').then(response => { console.log(response.data); }, response => { console.log("error"); }); } }
User.vue参考代码:
- <template>
- <div id="app">
- </div>
- </template>
- <script>
- import axios from "axios";
- export default {
- name: "app",
- data() {
- return {
- itemList: []
- }
- },
- mounted() {
- this.getData();
- },
- methods: {
- getData() {
- axios.get('/api/test.json').then(response => {
- console.log(response.data);
- }, response => {
- console.log("error");
- });
- }
- }
- }
- </script>
这个时候,我们可以看见,请求的数据
test.json:
- {
- "first":[
-
- {"name":"520","nick":"我爱你"},
-
- {"name":"521","nick":"我愿意"},
-
- {"name":"1314","nick":"一生一世"}
- ]
-
- }
- // mock code
- const express = require('express')
- const app = express()
- const posts = require('../mock/test.json')
- const routes = express.Router()
- app.use('/api', routes)
-
- // 如果是post请求,那么将get改为post即可
- devServer: {
- ...
- before(app){
- app.get('/api/test', (req, res) => {
- res.json(posts)
- })
-
- }
- }
成功看到模拟数据
- methods: {
- getData() {
- axios.get('http://localhost:8080/api/test').then(response => {
- console.log(response.data);
- }, response => {
- console.log("error");
- });
- }
- }
vue页面代码参考
- <template>
- <div id="app">
- </div>
- </template>
- <script>
- import axios from "axios";
- export default {
- name: "app",
- data() {
- return {
- itemList: []
- }
- },
- mounted() {
- this.getData();
- },
- methods: {
- getData() {
- axios.get('http://localhost:8080/api/test').then(response => {
- console.log(response.data);
- }, response => {
- console.log("error");
- });
- }
- }
- }
- </script>
5:在浏览器里面,我们可以看到,mock里面的数据请求成功显示如下
其实步骤很简单,代码如下
- <template>
- <div id="app">
- <div v-for="item in itemList">
- <span>{{item.name}}</span>
- <span>{{item.nick}}</span>
- </div>
- </div>
- </template>
- <script>
- import axios from "axios";
- export default {
- name: "app",
- data() {
- return {
- itemList: []
- }
- },
- mounted() {
- this.getData();
- },
- methods: {
- getData() {
- axios.get('http://localhost:8080/api/test').then(response => {
- console.log(response.data);
- this.itemList =response.data.first;
- }, response => {
- console.log("error");
- });
- }
- }
- }
- </script>
打开界面,既可以看到,所需要的数据一家展示在前端的界面了
接着之前的项目继续写,打开一个vue界面,在里面写如下代码:
- <template>
- <div>
- <el-table :data="tableData.slice((currentPage-1)*pagesize,currentPage*pagesize)" style="width: 100%">
- <el-table-column prop="id" label="日期" width="180">
- </el-table-column>
- <el-table-column prop="name" label="姓名" width="180">
- </el-table-column>
- <el-table-column prop="price" label="地址">
- </el-table-column>
- </el-table>
- <div class="pagination">
- <el-pagination
- @size-change="handleSizeChange"
- @current-change="handleCurrentChange"
- :current-page="currentPage"
- :page-sizes="[5, 10, 20, 40]"
- :page-size="pagesize"
- layout="total, sizes,prev, pager, next"
- :total="tableData.length"
- prev-text="上一页"
- next-text="下一页">
- </el-pagination>
- </div>
- </div>
- </template>
- <script>
- import axios from "axios";
- export default {
- name: "app",
- data() {
- return {
- currentPage: 1, //默认显示页面为1
- pagesize: 5, // 每页的数据条数
- tableData: [], //需要data定义一些,tableData定义一个空数组,请求的数据都是存放这里面
- }
- },
- mounted() {
- this.getData();
- },
- methods: {
- getData() {
- axios.get('http://localhost:8080/api/test').then(response => {
- console.log(response.data);
- this.tableData = response.data;
- }, response => {
- console.log("error");
- });
- },
- //每页下拉显示数据
- handleSizeChange: function(size) {
- this.pagesize = size;
- /*console.log(this.pagesize) */
- },
- //点击第几页
- handleCurrentChange: function(currentPage) {
- this.currentPage = currentPage;
- /*console.log(this.currentPage) */
- },
-
- }
- }
- </script>
test.json
- [
- {
- "id": 0,
- "name": "Item 0",
- "price": "徐家汇"
- },
- {
- "id": 1,
- "name": "Item 1",
- "price": "$1"
- },
- {
- "id": 2,
- "name": "Item 2",
- "price": "$2"
- },
- {
- "id": 3,
- "name": "Item 3",
- "price": "徐家汇"
- },
- {
- "id": 4,
- "name": "Item 4",
- "price": "徐家汇"
- },
- {
- "id": 5,
- "name": "Item 5",
- "price": "$5"
- },
- {
- "id": 6,
- "name": "Item 6",
- "price": "$6"
- },
- {
- "id": 7,
- "name": "Item 7",
- "price": "$7"
- },
- {
- "id": 8,
- "name": "Item 8",
- "price": "徐家汇"
- },
- {
- "id": 9,
- "name": "Item 9",
- "price": "$9"
- },
- {
- "id": 10,
- "name": "Item 10",
- "price": "$10"
- },
- {
- "id": 11,
- "name": "Item 11",
- "price": "$11"
- },
- {
- "id": 12,
- "name": "Item 12",
- "price": "徐家汇"
- },
- {
- "id": 13,
- "name": "Item 13",
- "price": "$13"
- },
- {
- "id": 14,
- "name": "Item 14",
- "price": "$14"
- },
- {
- "id": 15,
- "name": "Item 15",
- "price": "$15"
- },
- {
- "id": 16,
- "name": "Item 16",
- "price": "徐家汇"
- },
- {
- "id": 17,
- "name": "Item 17",
- "price": "$17"
- },
- {
- "id": 18,
- "name": "Item 18",
- "price": "$18"
- },
- {
- "id": 19,
- "name": "Item 19",
- "price": "徐家汇"
- },
-
- {
- "id": 20,
- "name": "Item 20",
- "price": "$20"
- }
- ]
效果如下
到这里就成功的实现了一个表格和分页了,数据是用mock模拟的,实际中换成后端的接口就可以了 。
