tabbar的封装 当然方法也很多,懒得写了直接贴代码吧

<template>
  <div id="table-bar" class="border-top-1px">
    <div class="items" @click='switchTab("Home")'
      :class="$route.path.indexOf('Home') !== -1? 'active' : ''">
      <div class="icon">
        <img v-if="$route.path.indexOf('Home') !== -1" 
          src="../images/icon_shouye.png" alt='active'/>
        <img v-else src="../images/icon_shouye2.png" alt="normal">
      </div>
      <div class="text">
        首页
      </div>
    </div>
    <div class="items" @click='switchTab("Order")'
      :class="$route.path.indexOf('Order') !== -1? 'active' : ''">
      <div class="icon">
        <img v-if="$route.path.indexOf('Order') !== -1" 
          src="../images/icon_dingdan.png" alt='active'>

      <div class="text">
        订单
      </div>
    </div>
    <div class="items" @click='switchTab("Mine")'
      :class="$route.path.indexOf('Mine') !== -1? 'active' : ''">
