最近vue不是特别火，自己想写一个vue 的底部菜单栏，然后试着开始写，起来还是听痛苦的，但是还是写出来，这个过程重查询了一些资料和看了一些视频。

1 写好界面

这是我写好的四个界面

2 在router.js重定义路由

在一级路由下面定义自己tabbr的子路由。

routes: [
  {
   path: '/',
   name: 'index',
   component:()=>import('./views/index'), //懒加载引入，路由
   children:[
    {path:'',redirect:'/charts'},//重定项
    {path:'/charts',name:'charts',component:()=>import('./views/charts.vue')},
    {path:'/adiscover',name:'adiscover',component:()=>import('./views/adiscover.vue')},
    {path:'/ybutton',ybutton:'ybutton',component:()=>import('./views/ybutton.vue')},
    {path:'/me',name:'me',component:()=>import('./views/me.vue')}
   ]
  },
]

3 封装tabbar底部菜单栏组件

<template>
<!-- <div class="footbar">
   <router-link to='/' tag='div'>
     <span>      <img :src="this.$route.path=='/charts'?'https://ss0.baidu.com/6ONWsjip0QIZ8tyhnq/it/u=3100024767,29226190&fm=58':'https://ss0.baidu.com/6ONWsjip0QIZ8tyhnq/it/u=3993527673,913427098&fm=58'" alt="">
     </span>
     <span>资产</span>
   </router-link>
   <router-link to='/adiscover' tag='div'>
     <span>      <img :src="this.$route.path=='/adiscover'?'https://10.url.cn/qqcourse_logo_ng/ajNVdqHZLLAcYPom22osQf2IIdMD25ofYUibd1USSQFHdiaUIiavicpAibgSReIqCky8gqY8ku5qdXsc/356':'https://ss0.baidu.com/6ONWsjip0QIZ8tyhnq/it/u=3993527673,913427098&fm=58'" alt="">
     </span>
     <span>商城</span>
   </router-link>
   <router-link to='/ybutton' tag='div'>
     <span>      <img :src="this.$route.path=='/ybutton'?'https://10.url.cn/qqcourse_logo_ng/ajNVdqHZLLAcYPom22osQf2IIdMD25ofYUibd1USSQFHdiaUIiavicpAibgSReIqCky8gqY8ku5qdXsc/356':'https://ss0.baidu.com/6ONWsjip0QIZ8tyhnq/it/u=3993527673,913427098&fm=58'" alt="">
     </span>
     <span>交易</span>
   </router-link>
   <router-link to='/me' tag='div'>
     <span>      <img :src="this.$route.path=='/me'?'https://10.url.cn/qqcourse_logo_ng/ajNVdqHZLLAcYPom22osQf2IIdMD25ofYUibd1USSQFHdiaUIiavicpAibgSReIqCky8gqY8ku5qdXsc/356':'https://ss0.baidu.com/6ONWsjip0QIZ8tyhnq/it/u=3993527673,913427098&fm=58'" alt="">
     </span>
     <span>我的</span>
   </router-link>
  </div> -->
<div class="footer">
    <router-link v-for="(item,index) in data" :key="index" :to="item.path">
      <div class="divs" @click="tab_click(item.path)">
        <i :class="item.icon==true?'red':'bloack'">1</i>
        <i>{{item.title}}</i>  
      </div>  
    </router-link>    
</div>
</template>
<script>
import { constants } from 'crypto';
export default {
  props:{
    data:Array
  },
  data(){
    return{ 
      datai:this.data
    }
  },
  created(){
  },
  mounted(){
    console.log(this.data)
  },
  methods:{
    tab_click(path){
      const that=this;
      let datary=this.data;
        for(let i=0;i<datary.length;i++){ 
            datary[i].icon=false;
          if(datary[i].path==path){ 
            datary[i].icon=true;
             console.log('---------',datary[i].path)
          }
        }    
      this.datai=datary;
      console.log(datary)      
    }
  }   
}
</script>
<style scoped>
.footer{
  position: fixed;
  bottom:0px;
  left:0px;
  width:100%;
  display:flex;
  justify-content: space-between;
}
.footer .divs{padding:10px;}
.red{color:red;font-size:14px;}
.bloack{font-size:14px;color:black;}
/* ---------------- */
 .footbar{
  width: 100%;
  height: 2.613333rem;
  position: fixed;
  bottom: 0;
  display: flex;
  align-items: center;
  background: white;
  border-top: 1px solid #eeeeee;
  color: #999999;
}
.footbar span{
  display: block;
  font-size: .64rem;
}
.footbar div{
  flex: 1;
  text-align: center;
}
.footbar img{
  height: 1.066667rem;
}
.footbar .router-link-exact-active{
  color: #2F83C3;
}
.footbar .active{
  color: #2F83C3;
}
</style>

4 显示底部菜单栏的界面引入tabbar 组件

<template>
  <div class="index">
    主页
    <router-view></router-view>
    <tabbar :data="tabbarData"/>
  </div>
</template>
<script>
import tabbar from '../components/tabbaer'
export default {
name:'index',
data() {
  return {
    tabbarData:[
      {title:'微信',icon:true,path:'/charts'},
      {title:'通讯录',icon:false,path:'/adiscover'},
      {title:'发现',icon:false,path:'/ybutton'},
      {title:'我的',icon:false,path:'/me'},
      ]
  }
},
components:{
  tabbar,
},
}
</script>
<style scoped>
  .index{
    width:100%;
    height:100%;
    overflow: hidden;
    padding:16px;
    box-sizing:border-box;
    }   
</style>
