前一篇已经安装好了Element UI环境,现在开始来实际操作框架提供的一些组件的运用了。
在准备好以下文章里面的内容之后,可以打开test.vue文件,开始写代码了。Vue框架Element UI教程-安装环境搭建(一)https://www.jianshu.com/p/ab3c34a95128
打开test.vue文件,开始写代码
<template>
<div>
<el-time-picker
is-range
v-model="value"
range-separator="-"
start-placeholder="开始时间"
end-placeholder="结束时间"
placeholder="选择时间范围">
</el-time-picker>
</div>
</template>
<script>
export default {
data() {
return {
value: [new Date(2016, 9, 10, 8, 40), new Date(2016, 9, 10, 9, 40)],
};
}
}
</script>
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
出现和隐藏动画
Vue框架Element UI教程-安装环境搭建(一)https://www.jianshu.com/p/ab3c34a95128
今天继续写组件的运用相关例子
点击按钮的时候,元素会呈现一个出现和隐藏的动画功能。
<template>
<div>
<el-button @click="show = !show">点击按钮</el-button>
<div style="display: flex; margin-top: 20px; height: 100px;">
<transition name="el-fade-in-linear">
<div v-show="show" class="transition-box">我会消失在人海之中</div>
</transition>
</div>
</div>
</template>
<script>
export default {
data: () => ({
show: true
})
}
</script>
<style>
.transition-box {
margin-bottom: 10px;
width: 300px;
height: 100px;
border-radius: 4px;
background-color: #42B983;
text-align: center;
color: #fff;
padding: 40px 20px;
box-sizing: border-box;
margin-left: 520px;
}
</style>
效果大家可以自行尝试。

在用Element UI框架的时候
<template>
<div>
<el-row class="tac">
<el-col :span="4">
<el-menu
default-active="2"
class="el-menu-vertical-demo"
@open="handleOpen"
@close="handleClose"
background-color="#545c64"
text-color="#fff"
active-text-color="#ffd04b">
<el-submenu index="1">
<template slot="title">
<i class="el-icon-s-platform"></i>
<span>服务大厅</span>
</template>
<el-menu-item-group>
<el-menu-item index="1-1">在场服务</el-menu-item>
<el-menu-item index="1-2">历史服务</el-menu-item>
</el-menu-item-group>
</el-submenu>
<el-submenu index="2">
<template slot="title">
<i class="el-icon-s-tools"></i>
<span>系统设置</span>
</template>
<el-menu-item-group>
<el-menu-item index="1-1">权限管理</el-menu-item>
<el-menu-item index="1-2">角色管理</el-menu-item>

</el-menu-item-group>
</el-submenu>
</el-menu>
</el-col>
</el-row>
</div>
</template>
<script>
export default {
methods: {
handleOpen(key, keyPath) {
console.log(key, keyPath);
},
handleClose(key, keyPath) {
console.log(key, keyPath);
}
}
}
</script>
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"
@open="handleOpen"
@close="handleClose"
background-color="#545c64"
text-color="#fff"
active-text-color="#ffd04b">
<el-menu-item v-for="(item,i) in navList" :key="i" :index="item.name">
<template slot="title">
<i class="el-icon-s-platform"></i>
<span> {{ item.navItem }}</span>
</template>
</el-menu-item>
</el-menu>
</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>
3:路由index.js
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
}, {
path: ‘/components/Management‘,
name: ‘Management‘,
component: Management
},
{
path: ‘/components/User‘,
name: ‘User‘,
component: User
},{
path: ‘/components/Personnel‘,
name: ‘Personnel‘,
component: Personnel
},{
path: ‘/components/Alarm‘,
name: ‘Alarm‘,
component: Alarm
}
]
})
4:新页面的内容,我写的比较简单,需要自己写下功能需求所在的代码
<template>
<div>
我是权限管理页面
</div>
</template>
<script>
</script>
<style>
</style>
5:效果就可以看了
axios请求数据
1:进入项目,npm安装
npm install axios --save
2.在main.js下引用axios
import axios from ‘axios‘
3:准备json数据
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
4:跨域问题,设置代理,利用proxyTable属性实现跨域请求
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
}
}
},
5:打开一个界面User.vue,开始写请求数据的方法
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>
6:再次运行
npm run dev
这个时候,我们可以看见,请求的数据
Mock的使用
1:在项目里面新建一个mock文件夹,在mock文件夹里面新建一个test.json文件
test.json:
{
"first":[
{"name":"520","nick":"我爱你"},
{"name":"521","nick":"我愿意"},
{"name":"1314","nick":"一生一世"}
]
}
2:在build目录下找到webpack.dev.conf.js文件,编写以下代码
// 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)
})
}
}
3:浏览器输入http://localhost:8080/api/test
成功看到模拟数据
4:使用第三方http请求库axios进行ajax请求,这里不会,可以从参考上一篇文章内容。
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

页面渲染
写了那么多,最终的数据都是要展示在前端的界面,才算是完成工作。
Element UI手册:https://cloud.tencent.com/developer/doc/1270
中文文档:http://element-cn.eleme.io/#/zh-CN
github地址:https://github.com/ElemeFE/element
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

axios表格分页
今天来写一个分页,表格分页在实际项目中经常用到,之前也写过关与bootstrap table 里面的表格分页,道理都差不多一样的,Element UI也有自己的组件可以用,话不多说,直接上代码了。
Element UI手册:https://cloud.tencent.com/developer/doc/1270
中文文档:http://element-cn.eleme.io/#/zh-CN
github地址:https://github.com/ElemeFE/element
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。
