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，

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>

5 这就是最终结果
