Bootstrap

Vue创建首页

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:

HTML部分:

<template>
    <div>
        <h1>欢迎访问教学管理系统</h1>
        <div class="home-container">
            <div id="main1"></div>
            <div id="main2"></div>
        </div>
        <div class="home-container">
            <div id="main3"></div>
            <div id="main4"></div>
        </div>
    </div>
</template>

CSS部分:

<style scoped>
h1 {
    text-align: center;
    color: #fff;
}

#main1,
#main2,
#main3,
#main4,
html,
body {
    width: 90%;
}

#main1,
#main2,
#main3,
#main4 {
    width: 700px;
    height: 400px;
}

.text {
    font-size: 14px;
}

.item {
    margin-bottom: 18px;
}

.clearfix:before,
.clearfix:after {
    display: table;
    content: "";
}

.clearfix:after {
    clear: both
}

.box-card {
    width: 480px;
}

.home-container {
    display: flex;
    justify-content: space-around;
}
</style>

JS部分:

先放个图片,这里是js全部。一下子复制过来太太太长了,给大家看下整体结构,按图片复制,别复制错了

  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',
                    x: 'left',
                    data: ['A', 'B', 'C', 'D', 'E']
                },
                series: [
                    {
                        type: 'pie',
                        radius: ['50%', '70%'],
                        avoidLabelOverlap: false,
                        label: {
                            show: false,
                            position: 'center'
                        },
                        labelLine: {
                            show: false
                        },
                        emphasis: {
                            label: {
                                show: true,
                                fontSize: '30',
                                fontWeight: 'bold'
                            }
                        },
                        data: [
                            { value: 335, name: 'A' },
                            { value: 310, name: 'B' },
                            { value: 234, name: 'C' },
                            { value: 135, name: 'D' },
                            { value: 1548, name: 'E' }
                        ]
                    }
                ]
            };
            myChart1.setOption(option1)
        },

 这里是methods的showData2函数:

showData2() {
            var myChart2 = this.echarts.init(document.getElementById('main2'), 'dark');
            var xAxisData = [];
            var data1 = [];
            var data2 = [];
            for (var i = 0; i < 100; i++) {
                xAxisData.push('A' + i);
                data1.push((Math.sin(i / 5) * (i / 5 - 10) + i / 6) * 5);
                data2.push((Math.cos(i / 5) * (i / 5 - 10) + i / 6) * 5);
            }
            var option2 = {
