uniapp踩坑之项目：简易版不同角色显示不一样的tabbar和页面-编程知识

1.

pages下创建三个不同用户身份的“我的”页面。

显示第几个tabbar，0是管理员 1是财务 2是司机

2.

在uni_modules文件夹创建底部导航cc-myTabbar文件夹，在cc-myTabbar文件夹创建components文件夹，在components文件夹创建cc-myTabbar.vue组件

3.

在utils文件夹创建tabBar.js

4.

pages.json里指定路径

5.

在单页面引入底部导航组件

//cc-myTabbar.vue 底部导航组件
<template><view class="page-total"><view class="tab-list"><view class="list" v-for="(item,index) in TabBarList" @click="onTabBar(item,index)" :style="{marginTop: (item.name == '') ?  '-88rpx' : '0px'}" :key="item.index"><image :src="item.acImg" mode="widthFix" v-show="tabBarShow ===index" :style="{width: (item.name == '') ?  '100rpx' : '54rpx',borderRadius: (item.name == '') ?  '24rpx' : '0rpx'}"></image><image :src="item.img" mode="widthFix" v-show="tabBarShow != index" :style="{width: (item.name == '') ?  '100rpx' : '54rpx',borderRadius: (item.name == '') ?  '24rpx' : '0rpx'}"></image><text :class="{'action':tabBarShow===index}">{{item.name}}</text></view></view></view>
</template><script>
