bug:
    因为通过router-link跳转,所以只能点击文字跳转,将router-link换成其他标签,然后设置跳转事件能改变这一bug
    
    因为非引入static内的图片,得用require引入

效果:

代码示例:

<template>
      <div class='foot'>
        <div class='nav'>
          <img :src="$route.path=='/home'?require('../../assets/tabs/1.png'):require('../../assets/tabs/2.png')" alt="">
          <router-link :to="{name:'home'}" :class="{colo:$route==='/home'}">外卖</router-link>
        </div>
        <div class='nav'>
          <img :src="$route.path=='/search'?require('../../assets/tabs/3.png'):require('../../assets/tabs/4.png')" alt="">
          <router-link :to="{name:'search'}">搜索</router-link>
        </div>
        <div class='nav'>
          <img :src="$route.path=='/order'?require('../../assets/tabs/5.png'):require('../../assets/tabs/6.png')" alt="">
          <router-link :to="{name:'order'}">订单</router-link>
        </div>
        <div class='nav'>
          <img :src="$route.path=='/person'?require('../../assets/tabs/7.png'):require('../../assets/tabs/8.png')" alt="">
          <router-link :to="{name:'person'}">我的</router-link>
        </div>
    
      </div>
    </template>
    
    <script>
      export default{ 
        data()
        { 
          return{ 
    
          }
        },
         methods:{ 
    
         }
      }
    </script>
    
    <style scoped>
     .foot>div>a{ 
        color: #bfbfbf;
        text-decoration: none;
    
      }
     .foot>div>a.active{ 
        color:#42af08;
      }
      .foot{ 
        height: 50px;
        width: 100%;
        position: absolute;
        bottom: 0;
        display: flex;
      }
      .foot>div{ 
        text-align: center;
        flex:1;
      }
      .foot>div>img{ 
        height: 30px;
        width: 30px;
        display: block;
        margin: 0 auto;
      }
    </style>
