vue如何实现自定义底部菜单栏

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: 'https://www.jb51.net/', 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> <router-link to='https://www.jb51.net/' 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> <router-link v-for="(item,index) in data" :key="index" :to="item.path"> <div @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> 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
