Vue创建首页
一、创建后台页面1.在前台components里创建loyout.vue组件，作为后台管理页面
·
上图是要实现的首页界面
一、创建首页页面
1.在前台components里创建Layout.vue组件，作为首页页面。
<template>
<div>首页</div>
</template>
<script>
export default {
}
</script>
<style>
</style>二、配置路由
1.去router下的index.js文件中去配置路由地址
{
path: "/",
name: "layout",
component: Layout,
}2.把Layout.vue组件引入到router下的index.js文件中
import Layout from "../components/Layout.vue";
三、搭建首页页面结构
1.搭建首页页面结构
<template>
<div>
<div class="header">头</div>
<div class="navbar">左</div>
<div class="main">主</div>
</div>
</template>
<script>
export default {
name: "Layout"
}
</script>
<style>
.header {
position: absolute;
line-height: 50px;
background-color: cornflowerblue;
padding: 0px;
top: 0px;
width: 100%;
}
.navbar {
position: absolute;
width: 230px;
top: 50px;
left: 0px;
background-color: rgb(182, 243, 39);
height: 100%;
}
.main {
position: absolute;
top: 50px;
left: 230px;
padding: 10px;
background-color: pink;
width: 100%;
height: 100%;
}
</style>2.把Layout.vue作为父组件，把头部，左侧，主体都抽离出来
在前台components文件夹下创建AppHeader文件夹，在此文件夹下，创建index.vue文件作为头部的组件，
<template>
<div>
<div class="header">头</div>
</div>
</template>
<script>
export default {
}
</script>
<style>
</style>在前台components文件夹下创建AppMain文件夹，在此文件夹下，创建index.vue文件作为主体的组件
<template>
<div>
<div class="main">zhuti</div>
</div>
</template>
<script>
export default {
}
</script>
<style>
</style>在前台components文件夹下创建AppHeader文件夹，在此文件夹下，创建index.vue文件作为头部的组件。
<template>
<div>
<div class="navbar">左边</div>
</div>
</template>
<script>
export default {
}
</script>
<style>
</style>3.抽离完Layout.vue的代码应该是这样：
<template>
<div>
<AppHeader />
<AppMain />
<AppNavbar />
</div>
</template>
<script>
import AppHeader from "./AppHeader/index.vue";
import AppMain from "./AppMain/index.vue";
import AppNavbar from "./AppNavbar/index.vue";
export default {
name: "Layout",
components: {
AppHeader,
AppMain,
AppNavbar
}
}
</script>
<style>
.header {
position: absolute;
line-height: 50px;
background-color: cornflowerblue;
padding: 0px;
top: 0px;
width: 100%;
}
.navbar {
position: absolute;
width: 230px;
top: 50px;
left: 0px;
background-color: rgb(182, 243, 39);
height: 100%;
}
.main {
position: absolute;
top: 50px;
left: 230px;
padding: 10px;
background-color: pink;
width: 100%;
height: 100%;
}
</style>四、布局实现
1.头部布局，AppHeader文件夹下的index.vue文件,去element官网找下拉菜单样式：
<template>
<div class="header">
<a href="#">
<img src="@/assets/logo.png" class="logo" alt="" />
<span class="company">学员管理系统</span>
</a>
<el-dropdown trigger="click" @command="handleCommand">
<span class="el-dropdown-link">
下拉菜单<i class="el-icon-arrow-down el-icon--right"></i>
</span>
<el-dropdown-menu slot="dropdown">
<el-dropdown-item icon="el-icon-plus" command="a">黄金糕</el-dropdown-item>
<el-dropdown-item icon="el-icon-circle-plus" command="b">狮子头</el-dropdown-item>
<!-- <el-dropdown-item icon="el-icon-circle-plus-outline">螺蛳粉</el-dropdown-item>
<el-dropdown-item icon="el-icon-check">双皮奶</el-dropdown-item>
<el-dropdown-item icon="el-icon-circle-check">蚵仔煎</el-dropdown-item> -->
</el-dropdown-menu>
</el-dropdown>
</div>
</template>
<script>
export default {
methods: {
handleCommand(command) {
this.$message('click on item ' + command);
}
}
};
</script>
<style scoped>
.logo{
vertical-align: middle;
width: 30px;
height: 30px;
padding: 0 10px 0 50px;
}
.company{
color:white;
}
a{
text-decoration: none;
}
.el-dropdown{
float: right;
margin-right: 40px;
cursor: pointer;
color: white;
}
</style>2.左侧导航栏布局，AppNavbar文件夹下的index.vue文件：
<template>
<div class="navbar">
<el-menu
:router="true"
:default-active="msg"
class="el-menu-vertical-demo"
background-color="#545c64"
text-color="#fff"
active-text-color="#ffd04b"
>
<el-menu-item index="/home">
<i class="el-icon-menu"></i>
<span slot="title">首页</span>
</el-menu-item>
<el-menu-item index="/teacher">
<i class="el-icon-apple"></i>
<span slot="title">老师</span>
</el-menu-item>
<el-menu-item index="/students">
<i class="el-icon-cloudy-and-sunny"></i>
<span slot="title">学生</span>
</el-menu-item>
</el-menu>
</div>
</template>
<script>
export default {
data () {
return {
msg:this.$route.path//默认选中当前路由路径
}
}
};
</script>
<style>
</style>3. 导航组件实现：el-menu 标签上有个 router="true" 属性开启导航路由功能，开启后 el-menu-item 的 index 属性指定路由地址。default-active 属性默认选中哪个菜单, 注意 v-bind:default-active 才可以指定表达式
五、所有菜单路由配置
1. 在 src\views 目录下创建 home、teacher、students 目录，并且每个目录下创建一个index.vue
2. 配置所有菜单路由信息，在 router文件下的index.js 中配置如下：先采用 import 导入组件。再路由引用组件，当成子集路由来使用。
import Vue from "vue";
import VueRouter from "vue-router";
import Register from "../views/register/index.vue";
import login from "../views/login/index.vue"
import layout from "../components/layout.vue"
import home from "../views/home/index.vue"
import teacher from "../views/teacher/index.vue"
import students from "../views/students/index.vue"
Vue.use(VueRouter);
const routes = [{
path: "/register",
name: "register",
component: Register,
}, {
path: "/login",
name: "login",
component: login,
}, {
path: "/",
name: "layout",
component: layout,
redirect: "/home",
children: [{ path: "/home", meta: { title: "首页" }, component: home }]
},
{
path: "/teacher",
name: "teacher",
component: layout,
children: [{
path: "/",
name: "teacher",
meta: { title: "老师管理" },
component: teacher,
}]
},
{
path: "/students",
name: "students",
component: layout,
children: [{
path: "/",
meta: { title: "学生管理" },
component: students,
}]
},
];
const router = new VueRouter({
routes,
});
export default router;3.因为他是一个子路由，所以要在AppMain下的index.vue里给个视口：
<template>
<div class="main">
<router-view></router-view>
</div>
</template>
<script>
export default {};
</script>
<style>
</style>六、右侧主区域实现
功能：当点击左侧菜单项后，对应路由组件渲染在右侧主区域中。所以要在右侧指定组件渲染出口。
1.主区域中除了 首页没有 横向指示导航，其他模块中都有，所以先渲染出面包屑,在AppMain文件夹下的index.vue文件。(在 Layout.vue 中的移除右侧主区域背景色， .main 中指定的。)
<template>
<div class="main">
<el-breadcrumb separator="/">
<el-breadcrumb-item :to="{ path: '/' }">首页</el-breadcrumb-item>
</el-breadcrumb>
<!-- 子路由渲染出口 -->
<router-view></router-view>
</div>
</template>
<script>
export default {};
</script>
<style scoped>
.el-breadcrumb{
height: 10px;
padding: 20px;
border-radius: 4px;
width: 100%;
box-shadow: 0 2px 12px 0 rgba(0,0,0,0.2 );
}
.el-breadcrumb_inner{
cursor: pointer !important;
}
</style>2. 将 横向指示导航 抽取为子组件 AppMain\Link.vue ，其中获取导航名称使用 $route.meta.title , 路由地址使用 $route.path
<template>
<div>
<el-breadcrumb separator="/">
<el-breadcrumb-item :to="{ path: $route.path }"
>{{$route.meta.title}}</el-breadcrumb-item>
</el-breadcrumb>
</div>
</template>
<script>
export default {};
</script>
<style scoped>
.el-breadcrumb{
height: 10px;
padding: 20px;
border-radius: 4px;
width: 100%;
box-shadow: 0 2px 12px 0 rgba(0,0,0,0.2 );
}
.el-breadcrumb_inner{
cursor: pointer !important;
}
</style>3.父组件，AppMain文件夹下的index.vue文件：
<template>
<div class="main">
<linka></linka>
<router-view></router-view>
</div>
</template>
<script>
import linka from './link.vue';
export default {
components: {
linka
}
};
</script>
<style>
</style>提示：我们在给组件命名时，不能和html标签的名字重复，如input命名组件的名字，会报错：
4. 在 AppMain\index.vue 中导入 Link.vue使用 v-show 判断路由为 /home 时不显示横向指示导航。
<template>
<div class="main">
<linka v-show="$route.path!=='/home'"></linka>
<router-view></router-view>
</div>
</template>
<script>
import linka from './link.vue';
export default {
components: {
linka
}
};
</script>
<style>
</style>5.我们让右上角显示用户的名字，回到AppHeafer\index.vue，我们将存储在localStorage里的用户昵称拿到，显示在页面上：
<template>
<div class="header">
<a href="#">
<img src="@/assets/bg.jpg" class="logo" alt="" />
<span class="company">学员管理系统</span>
</a>
<el-dropdown @command="handleCommand">
<span class="el-dropdown-link">
hi {{ userInfo }}<i class="el-icon-arrow-down el-icon--right"></i>
</span>
<el-dropdown-menu slot="dropdown">
<el-dropdown-item command="a">黄金糕</el-dropdown-item>
<el-dropdown-item command="b">狮子头</el-dropdown-item>
<el-dropdown-item command="c">螺蛳粉</el-dropdown-item>
<el-dropdown-item command="d" disabled>双皮奶</el-dropdown-item>
<el-dropdown-item command="e" divided>蚵仔煎</el-dropdown-item>
</el-dropdown-menu>
</el-dropdown>
</div>
</template>
<script>
export default {
name: "AppHeader",
data() {
return {
userInfo: ''
}
},
mounted() {
this.userInfo = JSON.parse(localStorage.getItem('sms-user')).nickname
console.log(this.userInfo);
},
};
</script>
稍微调整一下首页的样式，在App.vue里：
body {
// margin: 0;
margin: 0px auto;
overflow: hidden;
}
首页样式的实现——echarts
目前效果是这样的：
我想实现这样：这样首页看起来好看点，要用到echarts，这个工作中也常接触到，面试也会涉及一点，我们刚好熟悉一下，暂时先用假数据把他显示出来，后面我们自己在后台写点数据，模拟真实从后台请求数据，用echarts展示在页面上
一、首先引入Echarts
1.Echarts,一个基于 JavaScript 的开源可视化图表库 ,来布局一下Home页，在home的index.vue文件中，对了，得先下载
npm install echarts --save
2.然后在home的index.vue文件中添加如下：
<template>
<div>
<h1>欢迎访问教学管理系统</h1>
<div id="main"></div>
</div>
</template>
<script>
//这里是在当前home组件引入了echarts ，别的组件要想使用，还要再引入echarts
import * as echarts from 'echarts';
export default {
name: "Home",
mounted() {
this.showData()
},
methods: {
showData() {
// 基于准备好的dom，初始化echarts实例
var myChart = echarts.init(document.getElementById('main'));
// 绘制图表
myChart.setOption({
title: {
text: 'ECharts 入门示例'
},
tooltip: {},
xAxis: {
data: ['衬衫', '羊毛衫', '雪纺衫', '裤子', '高跟鞋', '袜子']
},
yAxis: {},
series: [
{
name: '销量',
type: 'bar',
data: [5, 20, 36, 10, 10, 20]
}
]
});
}
}
}
</script>
<style scoped>
h1 {
text-align: center;
color: #fff;
}
#main {
width: 500px;
height: 500px;
}
</style>注：如果想让所有组件可以使用echarts，我们把home下的index.vue中的引入命令剪切走，放到main.js中，在main.js中加入下面两行代码：
import * as echarts from 'echarts';// 让所有组件可以使用echarts
Vue.prototype.echarts=echarts//挂到原型上那么我们home下的index.vue中的echarts.init，就不能直接用echarts了，应该是this.echarts.init
var myChart = this.echarts.init(document.getElementById('main'));这样就能展示echarts图形了，如果引用多个，就要具备多个有大小的容器，下面是我做的效果，现在数据还是一份一份的，代码量较多，不好看，但是我现在还不会把他们抽离出来放到data里，以后我学会了，我再来修改这里，这是目前我做的效果图：
大家可以自己去echarts官网选自己喜欢的图形，这里是home的index.vue文件代码如下：
代码太长了，不好看，我分段给大家展示哈：

mounted() {
this.showData1()
this.showData2()
this.showData3()
this.showData4()
},这里是methods的showData1函数：
showData1() {
// 基于准备好的dom，初始化echarts实例
var myChart1 = this.echarts.init(document.getElementById('main1'), 'dark');
// 绘制图表
var option1 = {
legend: {
orient: 'vertical',

{ value: 135, name: 'D' },
{ value: 1548, name: 'E' }
]
}
]
};
myChart1.setOption(option1)
},这里是methods的showData2函数：

var myChart2 = this.echarts.init(document.getElementById('main2'), 'dark');
var xAxisData = [];

var data2 = [];
for (var i = 0; i < 100; i++) {
