Vue3实现简约型侧边栏的示例代码

作者:帅龍之龍

本文主要介绍了Vue3实现简约型侧边栏的示例代码,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧

有时遇到一些需求,需要实现左边侧边栏为父级菜单,右侧内容区的顶部为子级菜单,以及其底部为子级菜单对应的模块内容。

如此,简单实现如下:

1、首先配置好路由地址

【如:/src/router/index.ts】

import { createRouter, createWebHashHistory, RouteRecordRaw } from 'vue-router'
const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    redirect: '/xxxxxx'
  },
  {
    path: '/xxxxxx',
    name: '帅龍之龍',
    component: () => import('@/views/XXXXXX/index.vue'),
    children: [
      {
        path: '/xxxxxx/aaaaaa',
        name: '赤龍神帝',
        components: { AAAAAA: () => import('@/views/XXXXXX/AAAAAA/index.vue') },
        children: []
      },
      {
        path: '/xxxxxx/bbbbbb',
        name: '待定栏目',
        components: { BBBBBB: () => import('@/views/XXXXXX/BBBBBB/index.vue') },
        children: [],
      },
    ]
  }
]
const router = createRouter({
  history: createWebHashHistory(),
  routes
})
export default router

2、然后实现页面入口

【如:/src/views/XXXXXX/index.vue】

<template>
  <div class="index-page">
    <div class="index-page-navbar">
      <div class="index-page-navbar-item" :class="activePage == 'AAAAAA' ? 'index-page-navbar-active' : ''" @click="handleNavbarItemClick('AAAAAA')">
        <span>赤龍神帝</span>
      </div>
      <div class="index-page-navbar-item" :class="activePage == 'BBBBBB' ? 'index-page-navbar-active' : ''" @click="handleNavbarItemClick('BBBBBB')">
        <span>待定栏目</span>
      </div>
    </div>
    <div class="index-page-content">
      <router-view name="AAAAAA" v-if="activePage == 'AAAAAA'" />
      <router-view name="BBBBBB" v-if="activePage == 'BBBBBB'" />
    </div>
  </div>
</template>
<script>
export default {
  data () {
    return {
      // 当前激活的页面
      activePage: '',
    }
  },
  watch: {
  },
  created() {
    this.init()
  },
  mounted() {
    // 设置页面标题
    document.title = '帅龍之龍'
  },
  methods: {
    /**
     * 获取初始化参数
     */
    async init() {
      this.activePage = 'AAAAAA'
      const query = this.$route.query
      this.handleMatchRouter(this.activePage)
    },
    /**
     * 激活页面句柄
     */
    handleActivePageChange(activePage) {
      // 点击 el-tab 页面时,将 this.$route.query 置为 {}
      this.$route.query = {}
      this.handleMatchRouter(activePage)
    },
    /**
     * 激活页面句柄
     */
    handleMatchRouter(activePage) {
      const path = this.$route.path
      const b = path.toLowerCase().includes(activePage.toLowerCase())
      if (activePage == 'AAAAAA') {
        if (!b) {
          this.$router.push({
            path: '/xxxxxx/aaaaaa',
            query: this.$route.query,
          }) 
        }
      } else if (activePage == 'BBBBBB') {
        if (!b) {
          this.$router.push({
            path: '/xxxxxx/bbbbbb',
            query: this.$route.query,
          })
        }
      }
    },
    /**
     * 点击侧边导航栏
     */
    handleNavbarItemClick(item) {
      this.activePage = item
      this.$route.query = {}
      this.handleMatchRouter(item)
    },
  }
}
</script>
<style lang="less" scoped>
  .index-page {
    display: flex;
    flex-direction: row;
    width: 100%;
    height: 100%;
    position: relative;
    background-color: #fff;
    .index-page-navbar {
      flex: none;
      width: 40px;
      height: 100%;
      border-right: 1px solid #dfe1e6;
      .index-page-navbar-item {
        display: grid;
        width: 100%;
        height: 150px;
        background-color: #fff;
        border-bottom: 1px solid #dfe1e6;
        writing-mode: tb-rl;
        text-align: center;
        align-items: center;
        user-select: none;
        cursor: pointer;
        transition: all ease 0.3s;
        span {
          color: #303133;
          font-size: 14px;
          letter-spacing: 1.5px;
        }
      }
      .index-page-navbar-active {
        background-color: #5e7ce0;
        span {
          color: #fff;
        }
      }
    }
    .index-page-content {
      flex: 1;
      position: relative;
      height: 100%;
      margin: 0;
      padding: 0;
      overflow: hidden;
    }
  }
</style>

3、然后实现AAAAAA和BBBBBB页面

【如:/src/views/XXXXXX/AAAAAA/index.vue    /src/views/XXXXXX/BBBBBB/index.vue】

<template>
  <div style="width: 100%; height: 100%; display: grid; align-items: center; text-align: center">
    <span style="color: #303133; font-size: 14px;">HelloWorld!...</span>
  </div>
</template>

4、效果如下:~
