uniapp 根据角色控制页面显示

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

 

  1. //cc-myTabbar.vue 底部导航组件
  2. <template>
  3.   <view class="page-total">
  4.     <view class="tab-list">
  5.       <view class="list" v-for="(item,index) in TabBarList" @click="onTabBar(item,index)" :style="{marginTop: (item.name == '') ?  '-88rpx' : '0px'}" :key="item.index">
  6.         <image :src="item.acImg" mode="widthFix" v-show="tabBarShow ===index" :style="{width: (item.name == '') ?  '100rpx' : '54rpx',borderRadius: (item.name == '') ?  '24rpx' : '0rpx'}"></image>
  7.         <image :src="item.img" mode="widthFix" v-show="tabBarShow != index" :style="{width: (item.name == '') ?  '100rpx' : '54rpx',borderRadius: (item.name == '') ?  '24rpx' : '0rpx'}"></image>
  8.         <text :class="{'action':tabBarShow===index}">{{item.name}}</text>
  9.       </view>
  10.     </view>
  11.   </view>
  12. </template>
  13.  
  14. <script>
  15. import tabBar from "@/utils/tabBar.js"
  16. // 判断当前登陆用户角色
  17. // 0 为管理员
  18. // 1 为财务

  22. // var user_type = uni.getStorageSync("userType")
