基于vue2.x实现的即时通讯程序仿微信聊天3配置tabbar以

• 打开permission.js，将首页的页面path填写到白名单whiteList里

const whiteList = ['/login','/home'] // no redirect whitelist

• 然后访问首页路径

http://localhost:9020/#/home

• 下面配置tabbar，打开src/views/layouts/index.vue，修改tabbars数组

 tabbars: [
        {
          title: '通讯录',
          to: {
            name: 'Home'
          },
          icon: 'chat-o'
        },
        {
          title: '群聊',
          to: {
            name: 'GroupChat'
          },
          icon: 'friends-o'
        },
        {
          title: '我的',
          to: {
            name: 'About'
          },
          icon: 'user-o'
        }
      ]

• tabbar配置好了，下面删除src/views/home/index.vue中的代码

<template>
  <div>首页</div>
</template>

<script>
export default {}
</script>

<style lang="scss" scoped>
</style>

• 先来开发顶部的navbar和搜索框和滚动通告，需要用到vant组件库的NavBar 导航栏和Search 搜索和NoticeBar 通知栏

• 首先先引入NavBar 导航栏和Search 搜索
• 打开src/plugins/vant.js，引入这三个组件

import { NavBar, Search, NoticeBar } from 'vant';

Vue.use(NavBar);
Vue.use(Search);
Vue.use(NoticeBar);

• 开始编码开发这三个模块

<template>
  <div>
    <van-nav-bar title="回信（0）" left-text="">
      <template #right>
        <van-icon name="add-o" size="20" color="#333" />
      </template>
    </van-nav-bar>
    <van-search v-model="value" placeholder="请输入搜索关键词" />
    <van-notice-bar left-icon="volume-o" text="在代码阅读过程中人们说脏话的频率是衡量代码质量的唯一标准。" />
  </div>
</template>
<script>
export default {
  data() {
    return {
      value: ''
    }
  }
}
</script>
<style lang="scss" scoped>
</style>

• 开发完成

• html

<div class="cell">
      <ul>
        <li v-for="(item,index) in 12" :key="index">
          <div class="left">
            <van-image
              fit="cover"
              class="avatar"

            />
          </div>
          <div class="right">
            <div class="top">
              <span>钱多多 </span>
              <span></span>
              <span>12:00</span>
            </div>
            <div class="bottom">你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友你好啊，小朋友</div>
          </div>
        </li>
      </ul>
    </div>
