vue 封装tarbar组件

1。新建index.vue。引入tarbar组件

<template>
  <div class="index">
    <router-view></router-view>
    <TabBar :data="tabbarData"/>
  </div>
</template>

<script>
import TabBar from "../components/TabBar";
export default {
  name: "index",
  data() {
    return {
      tabbarData: [
        { title: "首页", icon: "home", path: "/home" },
        { title: "订单", icon: "file-text-o", path: "/order" },
        { title: "我的", icon: "user", path: "/me" }
      ]
    };
  },
  components: {
    TabBar
  }
};
</script>

<style scoped>
.index {
  width: 100%;
  height: calc(100% - 45px);
}
</style>

2.新建tabar组件

<template>
  <div class="tabbar">
    <router-link
      class="tab-item"
      v-for="(item,index) in data"
      :key="index"
      :to="item.path"
      active-class="is-selected"
    >
      <div class="tab-item-icon">
        <i :class="'fa fa-' + item.icon"></i>
      </div>
      <div class="tab-item-label">{{item.title}}</div>
    </router-link>
  </div>
</template>

<script>
export default {
  name: "tabbar",
  props: {
    data: Array
  }
};
</script>

<style scoped>
.tabbar {
  height: 45px;
  box-sizing: border-box;
   100%;
  position: fixed;
  bottom: 0;
  background-image: linear-gradient(
    180deg,
    #d9d9d9,
    #d9d9d9 50%,
    transparent 0
  );
  background-size: 100% 1px;
  background-repeat: no-repeat;
  background-position: 0 0;
  background-color: #fafafa;
  display: flex;
  text-align: center;
}
.tab-item {
  display: block;
  padding: 3px 0;
  flex: 1;
}
.tab-item-icon {
   20px;
  height: 20px;
  margin: 0 auto 5px;
}
.tab-item-icon i {
  font-size: 16px;
}
.tab-item-label {
  color: inherit;
  font-size: 10px;
  line-height: 1;
}
a {
  text-decoration: none;
  color: #999;
}
.is-selected {
  color: #009eef;
}
</style>

　　。在router.js

import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
export default new Router({
  routes: [
    {
      path: '/',
      // name: 'index',
      component: () => import('@/components/index.vue'),
            children:[
        {
          path: '',
          redirect: '/home'
        },
        {
          path: '/home',
          name: 'home',
          component: ()=>import('@/components/home')
        },
        {
          path: '/order',
          name: 'order',
          component: ()=>import('@/components/order')
        },
        {
          path: '/me',
          name: 'me',
          component: ()=>import('@/components/My')
        },
      ]
    }

  ],

})

最后引入公共的css

<link

rel="stylesheet"
/>
