第二种

<template>
  <div class="tool-bar">
    <div
      class="tool-bar-item"
      v-for="(item, index) in toolBarData"
      :key="index"
      @click="onChangeFragement(item, index)"
    >
      <img
        class="tool-bar-item-img"
        :src="[index === selectItemIndex ? item.hIcon : item.nIcon]"
      />
      <div
        class="tool-bar-item-name"
        :class="{'tool-bar-item-name-h' : index === selectItemIndex}"
      >
        {
     {
     item.name}}
      </div>
    </div>
  </div>
</template>

<script>
export default {
     
  data() {
     
    return {
     
      toolBarData: [
        {
     
          // 这个是 vue 里面配置的别名,只要路径正确即可
          nIcon: require("@img/home-n.svg"),
          hIcon: require("@img/home-h.svg"),
          name: "首页",
          componentName: "home",
        },
        {
     
          nIcon: require("@img/shopping-n.svg"),
          hIcon: require("@img/shopping-h.svg"),
          name: "购物车",
          componentName: "shopping",
        },
        {
     
          nIcon: require("@img/my-n.svg"),
          hIcon: require("@img/my-h.svg"),
          name: "我的",
          componentName: "my",
        },
      ],
      selectItemIndex: 0,
    }
  },
  methods: {
     
    onChangeFragement(item, index) {
     
      this.selectItemIndex = index
      this.$emit('onChangeFragement', item.componentName)
    }
  },
}
</script>

<style lang="scss" scoped>
.tool-bar {
     
  width: 100%;
  height: px2rem(46);
  display: flex;
  justify-content: space-around;
  background-color: #fff;
  box-shadow: 0 0 16px 0 rgba(0, 0, 0, 0.2);
  border-top: 1px solid #e5e5e5;

  &-item {
     
    text-align: center;
    padding: px2rem(4) px2rem(12);
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;

    &-img {
     
      width: px2rem(22);
      height: px2rem(22);
    }

    &-name {
     
      font-size: 14px;
      margin-top: px2rem(4);

      &-h {
     
        color: #d81e06;
      }
    }
  }
}
</style>


(里面的 px2rem() 是为了做适配设置,
配置方法可以看这篇文章https://blog.csdn.net/qq_43477721/article/details/108235590)
(如果不想这样配置,可以将 px2rem() 这个函数里面的值提取出来,加上 px 就可以使用了,)

调用组价处
<template>
  <div class="main">
    <component :is="curentComponent"></component>
    <toolBar @onChangeFragement="onChangeFragement"></toolBar>
  </div>
</template>

<script>
import toolBar from '@c/currency/ToolBar.vue'
export default {
     
  components: {
     
    toolBar,
    'home': () => import('@c/Home'),
    'shopping': () => import('@c/Shopping'),
    'my': () => import('@c/My')
  },
  data() {
     
    return {
     
      curentComponent: 'home'
    }
  },
  methods: {
     
    onChangeFragement(componentName) {
     
      this.curentComponent =componentName
    }
  },
}
</script>

<style lang="scss" scoped>
.main {
     
  width: 100%;
  height: 100%;
  display: flex;
  flex-direction: column;
}
</style>
