TabBar实现思路

实现代码

TabBar.vue

<template>
  <div class="tab-bar">     
      <slot></slot>
  </div>
</template>

<script>
export default {
  name: 'TabBar',
  data() { 
    return {
    }
  }
 }
</script>

<style scoped>
.tab-bar{
  display: flex;
  background-color: #f6f6f6;
  
  position: fixed;
  left: 0;
  right: 0;
  bottom: 0;

  box-shadow: 0 -3px 1px rgba(100, 100, 100, 0.1);
}

</style>

TabBarItem.vue

<template>
  <div class="tab-bar-item" @click="itemClick()">
      <div v-if = "!isActive"><slot name = "item-icon"></slot></div>
      <div v-else><slot name = "item-icon-active"></slot></div>
      
      <div :style="activeStyle"><slot name = "item-text"></slot></div>
      
    <!-- <img src = "../../assets/img/tabbar/home.svg" alt="">
    <div>首页</div> -->
  </div>
</template>

<script>
export default {
  name: 'TabBarItem',
  props: {
    path: String,
    activeColor:{
      type: String,
      default: 'red',
    }
  },
  data() { 
    return {
        // isActive: false
    }
  },
  computed:{
    isActive(){
      return this.$route.path.indexOf(this.path) !== -1
    },
    activeStyle(){
      return this.isActive ? {color:this.activeColor}:{}
    }
  },
  methods:{
    itemClick(){
      if(this.$route.path != this.path)
       { this.$router.replace(this.path)}
    }
  }
 }
</script>

<style scoped>
.tab-bar-item{
  flex: 1;
  text-align: center;
  height: 49px;
}
.tab-bar-item img{
    width:24px;
    height: 24px;
    margin-top: 3px;
    vertical-align: middle;
}
.active{
    color: blueviolet;
}
</style>

MainTabBar.vue

<template>
  <div class="main-tab-bar">
          <tab-bar>
  
      <tab-bar-item path="/home" activeColor="blue">
        <img slot="item-icon" src = "~assets/img/tabbar/home.svg">
        <img slot="item-icon-active" src = "~assets/img/tabbar/home-active.svg">
        <div slot="item-text">首页</div>
      </tab-bar-item>

      <tab-bar-item path="/category" activeColor="blue">
        <img slot="item-icon" src = "~assets/img/tabbar/category.svg">
        <img slot="item-icon-active" src = "~assets/img/tabbar/category-active.svg">
        <div slot="item-text">分类</div>
      </tab-bar-item>
      <tab-bar-item path="/shopcart" activeColor="blue">
        <img slot="item-icon" src = "~assets/img/tabbar/shopcart.svg">
        <img slot="item-icon-active" src = "~assets/img/tabbar/shopcart-active.svg">
        <div slot="item-text">购物车</div>
      </tab-bar-item>
      <tab-bar-item path="/profile" activeColor="blue">
        <img slot="item-icon" src = "~assets/img/tabbar/profile.svg">
        <img slot="item-icon-active" src = "~assets/img/tabbar/profile-active.svg">
        <div slot="item-text">我的</div>
      </tab-bar-item>
    </tab-bar>
    
  </div>
</template>

<script>
import TabBar from 'components/tabbar/TabBar';
import TabBarItem from 'components/tabbar/TabBarItem';
export default {
  name: 'MainTabBar',
  data() { 
    return {

    }
  },
    components: {
    TabBar,
    TabBarItem
  }
 }
</script>

<style lang="" scoped>
</style>

App.vue

<template>
  <div id="app">
    <router-view></router-view>
    <main-tab-bar></main-tab-bar>
  </div>
</template>

<script>
import MainTabBar from './components/MainTabBar'
export default {
  name: 'App',
  components: {
    MainTabBar
  }
}
</script>

<style scoped>
@import "./assets/css/base.css";

</style>
