vue3后台管理系统之顶部tabbar组件搭建

1.1静态页面搭建

javascript 复制代码

<template>
    <div class="tabbar">
        <div class="tabbar_left">
            <!-- 面包屑 -->
            <Breadcrumb />
        </div>
        <div class="tabbar_right">
            <!-- 设置 -->
            <Setting />
        </div>
    </div>
</template>

<script setup lang="ts">
import Breadcrumb from './breadcrumb/index.vue'
import Setting from './setting/index.vue'
</script>
<script lang="ts">
export default {
    name: 'Tabbar',
}
</script>
<style scoped lang="scss">
.tabbar {
    width: 100%;
    height: 100%;
    display: flex;
    justify-content: space-between;
    // background-image: linear-gradient(to right, rgb(232, 223, 223), rgb(201, 178, 178), rgb(197, 165, 165));

    .tabbar_left {
        display: flex;
        align-items: center;
        margin-left: 20px;
    }

    .tabbar_right {
        display: flex;
        align-items: center;
    }
}
</style>

面包屑

javascript 复制代码

<template>
  <!-- 顶部左侧静态 -->
  <el-icon style="margin-right: 10px" @click="changeIcon">
    <!-- <component :is="LayOutSettingStore.fold ? 'Fold' : 'Expand'" /> -->
  </el-icon>
  <!-- 左侧面包屑 -->
  <el-breadcrumb separator-icon="ArrowRight">
    <!-- 面包动态展示路由名字与标题 -->
    <el-breadcrumb-item v-for="(item, index) in $route.matched" v-show="item.meta.title" :key="index" :to="item.path">
      <!-- 图标 -->
      <el-icon>
        <component :is="item.meta.icon" />
      </el-icon>
      <!-- 面包屑展示匹配路由的标题 -->
      <span>{{ item.meta.title }}</span>
    </el-breadcrumb-item>
  </el-breadcrumb>
</template>

<script setup lang="ts">
import { useRoute } from 'vue-router'

// //获取layout配置相关的仓库
// const LayOutSettingStore = useLayOutSettingStore()
//获取路由对象
const $route = useRoute()
console.log($route.matched, '111')

//点击图标的方法
const changeIcon = () => {
  //图标进行切换
  LayOutSettingStore.fold = !LayOutSettingStore.fold
}
</script>
<script lang="ts">
export default {
  name: 'Breadcrumb'
}
</script>

<style scoped></style>

1.2菜单折叠效果实现

javascript 复制代码

//小仓库:layout组件相关配置仓库
import { defineStore } from 'pinia'

const useLayOutSettingStore = defineStore('SettingStore', {
    state: () => {
        return {
            fold: false, //用户控制菜单折叠还是收起控制
            refsh: false, //仓库这个属性用于控制刷新效果
        }
    },
})

export default useLayOutSettingStore

动态判断菜单是否折叠，然后情况修改样式

javascript 复制代码

<template>
    <div class="layout_container">
        <!-- 左侧导航 -->
        <div
            class="layout_slider"
            :class="{ fold: LayOutSettingStore.fold ? true : false }"
        >
            <Logo />
            <!-- 展示菜单 -->
            <!-- 滚动组件 -->
            <el-scrollbar class="scrollbar">
                <!-- 菜单组件-->
                <el-menu
                    :collapse="LayOutSettingStore.fold ? true : false"
                    :default-active="$route.path"
                    background-color="#001529"
                    text-color="white"
                    active-text-color="yellowgreen"
                >
                    <!-- 根据路由动态生成菜单 -->
                    <Menu :menuList="userStore.menuRoutes"></Menu>
                </el-menu>
            </el-scrollbar>
        </div>
        <!-- 顶部导航 -->
        <div
            class="layout_tabbar"
            :class="{ fold: LayOutSettingStore.fold ? true : false }"
        >
            <Tabbar></Tabbar>
        </div>
        <!-- 内容展示区 -->
        <div
            class="layout_main"
            :class="{ fold: LayOutSettingStore.fold ? true : false }"
        >
            <router-view></router-view>
        </div>
    </div>
</template>
<script setup lang="ts">

            left: $base-menu-min-width;
            background-color: #fff;
        }
    }

    .layout_main {

            left: $base-menu-min-width;
        }
    }
}
</style>

1.3面包屑的实现

javascript 复制代码

<template>
    <!-- 顶部左侧静态 -->
    <el-icon style="margin-right: 10px" @click="changeIcon">
        <component
            :is="LayOutSettingStore.fold ? 'Fold' : 'Expand'"
        ></component>
    </el-icon>
    <!-- 左侧面包屑 -->
    <el-breadcrumb separator-icon="ArrowRight">
        <!-- 面包动态展示路由名字与标题 -->
        <el-breadcrumb-item
            v-for="(item, index) in $route.matched"
            :key="index"
            v-show="item.meta.title"
            :to="item.path"
        >
            <!-- 图标 -->
            <el-icon>
                <component :is="item.meta.icon"></component>
            </el-icon>
            <!-- 面包屑展示匹配路由的标题 -->
            <span>{{ item.meta.title }}</span>
        </el-breadcrumb-item>
    </el-breadcrumb>
</template>

<script setup lang="ts">
import { useRoute, useRouter } from 'vue-router'
import useLayOutSettingStore from '@/store/moudules/setting'
//获取layout配置相关的仓库
let LayOutSettingStore = useLayOutSettingStore()
//获取路由对象
let $route = useRoute()
console.log($route)
console.log($route.matched, '111')
let $router = useRouter()
console.log($router, '111')

//点击图标的方法
const changeIcon = () => {
    //图标进行切换
    LayOutSettingStore.fold = !LayOutSettingStore.fold
}
</script>
<script lang="ts">
export default {
    name: 'Breadcrumb',
}
</script>

<style scoped></style>

1.4刷新业务的实现

设置一个全局变量

javascript 复制代码

//获取骨架的小仓库
import useLayOutSettingStore from '@/store/modules/setting'
const layoutSettingStore = useLayOutSettingStore()
//刷新按钮点击回调
const updateRefsh = () => {
  layoutSettingStore.refsh = !layoutSettingStore.refsh
}

javascript 复制代码

<template>
    <!-- 路由组件出口的位置 -->
    <router-view v-slot="{ Component }">
        <transition name="fade">
            <!-- 渲染layout一级路由组件的子路由 -->
            <component :is="Component" v-if="flag" />
        </transition>
    </router-view>
</template>

<script setup lang="ts">
import { watch, ref, nextTick } from 'vue'
import useLayOutSettingStore from '@/store/moudules/setting'
let layOutSettingStore = useLayOutSettingStore()

//控制当前组件是否销毁重建
let flag = ref(true)

//监听仓库内部数据是否发生变化,如果发生变化，说明用户点击过刷新按钮
watch(
    () => layOutSettingStore.refsh,
    () => {
        //点击刷新按钮:路由组件销毁
        flag.value = false
        nextTick(() => {
            flag.value = true
        })
    },
)
</script>
<script lang="ts">
export default {
    // eslint-disable-next-line vue/no-reserved-component-names
    name: 'Main',
}
</script>

<style scoped>
.fade-enter-from {
    opacity: 0;
    transform: scale(0);
}

.fade-enter-active {
    transition: all 0.3s;
}

.fade-enter-to {
    opacity: 1;
    transform: scale(1);
}
</style>

1.5全屏功能的实现

javascript 复制代码

//全屏按钮点击的回调
const fullScreen = () => {
  //DOM对象的一个属性:可以用来判断当前是不是全屏模式[全屏:true,不是全屏:false]
  const full = document.fullscreenElement
  //切换为全屏模式
  if (!full) {
    //文档根节点的方法requestFullscreen,实现全屏模式
    document.documentElement.requestFullscreen()
  } else {
    //变为不是全屏模式->退出全屏模式
    document.exitFullscreen()
  }
}

1.6获取用户信息

javascript 复制代码

//获取用户信息方法
        async userInfo() {
            //获取用户信息进行存储仓库当中[用户头像、名字]

            const result: userInfoReponseData = await reqUserInfo()
            console.log(result)
            //如果获取用户信息成功，存储一下用户信息
            if (result.code == 200) {
                this.username = result.data.checkUser.username
                this.avatar = result.data.checkUser.avatar
            }
        },

javascript 复制代码

import axios from 'axios'
import { ElMessage } from 'element-plus'
//引入用户相关的仓库
import useUserStore from '@/store/modules/user'
//创建axios实例
const request = axios.create({
  baseURL: import.meta.env.VITE_APP_BASE_URL,

  timeout: 5000
})
//请求拦截器
request.interceptors.request.use((config) => {
  //获取用户相关的小仓库:获取仓库内部token,登录成功以后携带给服务器
  const userStore = useUserStore()
  if (userStore.token) {
    config.headers.token = userStore.token
  }
  //config配置对象,headers属性请求头,经常给服务器端携带公共参数
  //返回配置对象
  return config
})
//响应拦截器
request.interceptors.response.use(
  (response) => {
    return response.data
  },
  (error) => {
    //处理网络错误
    let msg = ''
    const status = error.response.status
    switch (status) {
      case 401:
        msg = 'token过期'
        break
      case 403:
        msg = '无权访问'
        break
      case 404:
        msg = '请求地址错误'
        break
      case 500:
        msg = '服务器出现问题'
        break
      default:
        msg = '无网络'
    }
    ElMessage({
      type: 'error',
      message: msg
    })
    return Promise.reject(error)
  }
)
export default request

1.7退出登录业务

javascript 复制代码

// 存储
export const SET_TOKEN = (token: string) => {
  localStorage.setItem('TOKEN', token)
}
// 读取
export const GET_TOKEN = () => {
  return localStorage.getItem('TOKEN')
}
// 移除token
export const REMOVE_TOKEN = () => {
  localStorage.removeItem('TOKEN')
}

javascript 复制代码

userLogout() {
            this.token = ''
            this.username = ''
            this.avatar = ''
            REMOVE_TOKEN()
        },

javascript 复制代码

//退出登录点击回调
const logout = async () => {
    //第一件事情:需要向服务器发请求[退出登录接口]******
    //第二件事情:仓库当中关于用于相关的数据清空[token|username|avatar]
    //第三件事情:跳转到登录页面
    //跳转到登录页面
    userStore.userLogout()
    $router.push({ path: '/login', query: { redirect: $route.path } })
}

再设置一个退出登录再登录返回原来的路由
