一个通过使用tabbar切换路由的组件

 

点击下面的tab，跳转到指定的路由，注意每次该页面激活时需要根据页面的路由来设置对应 的tab为激活状态，否则，再某一页面刷新后可能会出现tab和显示的路由不匹配的问题

<template>
  <div class="tabs">
    <div v-for="tab,index in tabs" :key="index">
      <div class="tab" @click="changeTab(tab,index)">
        <!--:style="'background-image: url('+tab.base+');background-size:100% 100%'" class="tab"-->
        <img :src="cur_index==index ? tab.active : tab.base" alt="" class="tab-img">
        <span class="tab-name" :style="cur_index==index ? 'color: #1296db':'color:rgb(111,111,111)'">{{tab.name}}</span>
      </div>
    </div>
  </div>
</template>

<script>
  export default {
    name: "tab",
    data() {
      return {
        cur_index: 0,
        tabs: [

          },

      next() {

        this.$router.push(this.tabs[this.cur_index].path)

    mounted() {
      // 避免刷新后tab 显示的高亮按钮与路由对不上
      var test = window.location.href.split('#')[1];
