代码演示

基础用法

v-model默认绑定选中标签的索引值，通过修改v-model即可切换选中的标签

<van-tabbar v-model="active">
  <van-tabbar-item icon="home-o">标签</van-tabbar-item>
  <van-tabbar-item icon="search">标签</van-tabbar-item>
  <van-tabbar-item icon="friends-o">标签</van-tabbar-item>
  <van-tabbar-item icon="setting-o">标签</van-tabbar-item>
</van-tabbar>

export default {
  data() {
    return {
      active: 0
    }
  }
}

通过名称匹配

在标签指定name属性的情况下，v-model的值为当前标签的name

<van-tabbar v-model="active">
  <van-tabbar-item name="home" icon="home-o">标签</van-tabbar-item>
  <van-tabbar-item name="search" icon="search">标签</van-tabbar-item>
  <van-tabbar-item name="friends" icon="friends-o">标签</van-tabbar-item>
  <van-tabbar-item name="setting" icon="setting-o">标签</van-tabbar-item>
</van-tabbar>

export default {
  data() {
    return {
      active: 'home'
    }
  }
}

显示徽标

<van-tabbar v-model="active">
  <van-tabbar-item icon="home-o">标签</van-tabbar-item>
  <van-tabbar-item icon="search" dot>标签</van-tabbar-item>
  <van-tabbar-item icon="friends-o" info="5">标签</van-tabbar-item>
  <van-tabbar-item icon="setting-o" info="20">标签</van-tabbar-item>
</van-tabbar>

自定义图标

通过 icon 插槽自定义图标，可以通过 slot-scope 判断标签是否选中

<van-tabbar v-model="active">
  <van-tabbar-item info="3">
    <span>自定义</span>
    <img
      slot="icon"
      slot-scope="props"
      :src="props.active ? icon.active : icon.normal"
    >
  </van-tabbar-item>
  <van-tabbar-item icon="search">标签</van-tabbar-item>
  <van-tabbar-item icon="setting-o">标签</van-tabbar-item>
</van-tabbar>

export default {
  data() {
    return {
      active: 0,
      icon: {
        normal: '//img.yzcdn.cn/icon-normal.png',
        active: '//img.yzcdn.cn/icon-active.png'
      }
    }
  }
}

自定义颜色

<van-tabbar
  v-model="active"
  active-color="#07c160"
  inactive-color="#000"
>
  <van-tabbar-item icon="home-o">标签</van-tabbar-item>
  <van-tabbar-item icon="search">标签</van-tabbar-item>
  <van-tabbar-item icon="freinds-o">标签</van-tabbar-item>
  <van-tabbar-item icon="setting-o">标签</van-tabbar-item>
</van-tabbar>

路由模式

标签栏支持路由模式，用于搭配vue-router使用。路由模式下会匹配页面路径和标签的to属性，并自动选中对应的标签

<router-view />
<van-tabbar route>
  <van-tabbar-item
    replace
    to="/home"
    icon="home-o"
  >
    标签
  </van-tabbar-item>
  <van-tabbar-item
    replace
    to="/search"
    icon="search"
  >
    标签
  </van-tabbar-item>
</van-tabbar>
