Radio 单选框

引入

import Vue from 'vue';
import { RadioGroup, Radio } from 'vant';
Vue.use(Radio);
Vue.use(RadioGroup);

代码演示

基础用法

通过v-model绑定值当前选中项的 name

<van-radio-group v-model="radio">
  <van-radio name="1">单选框 1</van-radio>
  <van-radio name="2">单选框 2</van-radio>
</van-radio-group>

export default {
  data() {
    return {
      radio: '1',
    };
  },
};

水平排列

将direction属性设置为horizontal后，单选框组会变成水平排列

<van-radio-group v-model="radio" direction="horizontal">
  <van-radio name="1">单选框 1</van-radio>
  <van-radio name="2">单选框 2</van-radio>
</van-radio-group>

禁用状态

通过disabled属性禁止选项切换，在Radio上设置disabled可以禁用单个选项

<van-radio-group v-model="radio" disabled>
  <van-radio name="1">单选框 1</van-radio>
  <van-radio name="2">单选框 2</van-radio>
</van-radio-group>

自定义形状

将shape属性设置为square，单选框的形状会变成方形

<van-radio-group v-model="radio">
  <van-radio name="1" shape="square">单选框 1</van-radio>
  <van-radio name="2" shape="square">单选框 2</van-radio>
</van-radio-group>

自定义颜色

通过checked-color属性设置选中状态的图标颜色

<van-radio-group v-model="radio">
  <van-radio name="1" checked-color="#07c160">单选框 1</van-radio>
  <van-radio name="2" checked-color="#07c160">单选框 2</van-radio>
</van-radio-group>

自定义大小

通过icon-size属性可以自定义图标的大小

<van-radio-group v-model="radio">
  <van-radio name="1" icon-size="24px">单选框 1</van-radio>
  <van-radio name="2" icon-size="24px">单选框 2</van-radio>
</van-radio-group>

自定义图标

通过icon插槽自定义图标，并通过slotProps判断是否为选中状态

<van-radio-group v-model="radio">
  <van-radio name="1">
    单选框 1
    <template #icon="props">
      <img class="img-icon" :src="props.checked ? activeIcon : inactiveIcon" />
    </template>
  </van-radio>
  <van-radio name="2">
    单选框 2
    <template #icon="props">
      <img class="img-icon" :src="props.checked ? activeIcon : inactiveIcon" />
    </template>
  </van-radio>
</van-radio-group>
<style>
  .img-icon {
    height: 20px;
  }
</style>

export default {
  data() {
    return {
      radio: '1',
      activeIcon: 'https://img.yzcdn.cn/vant/user-active.png',
      inactiveIcon: 'https://img.yzcdn.cn/vant/user-inactive.png',
    };
  },
};

禁用文本点击

设置label-disabled属性后，点击图标以外的内容不会触发单选框切换

<van-radio-group v-model="radio">
  <van-radio name="1" label-disabled>单选框 1</van-radio>
  <van-radio name="2" label-disabled>单选框 2</van-radio>
</van-radio-group>

与 Cell 组件一起使用

此时你需要再引入Cell和CellGroup组件

<van-radio-group v-model="radio">
  <van-cell-group>
    <van-cell title="单选框 1" clickable @click="radio = '1'">
      <template #right-icon>
        <van-radio name="1" />
      </template>
    </van-cell>
    <van-cell title="单选框 2" clickable @click="radio = '2'">
      <template #right-icon>
        <van-radio name="2" />
      </template>
    </van-cell>
  </van-cell-group>
</van-radio-group>
