在一组备选项中进行单选

基础用法

由于选项默认可见，不宜过多，若选项过多，建议使用 Select 选择器。

要使用 Radio 组件，只需要设置v-model绑定变量，选中意味着变量的值为相应 Radio ​label​属性的值，​label​可以是​String​、​Number​或​Boolean​。

<template>
  <div>
    <el-radio v-model="radio1" label="1">备选项1</el-radio>
    <el-radio v-model="radio1" label="2">备选项2</el-radio>
  </div>
  <div>
    <el-radio v-model="radio2" label="1" size="medium">备选项1</el-radio>
    <el-radio v-model="radio2" label="2" size="medium">备选项2</el-radio>
  </div>
  <div>
    <el-radio v-model="radio3" label="1" size="small">备选项1</el-radio>
    <el-radio v-model="radio3" label="2" size="small">备选项2</el-radio>
  </div>
  <div>
    <el-radio v-model="radio4" label="1" size="mini">备选项1</el-radio>
    <el-radio v-model="radio4" label="2" size="mini">备选项2</el-radio>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        radio1: '1',
        radio2: '1',
        radio3: '1',
        radio4: '1',
      }
    },
  }
</script>

禁用状态

单选框不可用的状态。

只要在el-radio元素中设置disabled属性即可，它接受一个Boolean，true为禁用。

<template>
  <el-radio disabled v-model="radio" label="禁用">备选项</el-radio>
  <el-radio disabled v-model="radio" label="选中且禁用">备选项</el-radio>
</template>

<script>
  export default {
    data() {
      return {
        radio: '选中且禁用',
      }
    },
  }
</script>

单选框组

适用于在多个互斥的选项中选择的场景

结合el-radio-group元素和子元素el-radio可以实现单选组，在el-radio-group中绑定v-model，在el-radio中设置好label即可，无需再给每一个el-radio绑定变量，另外，还提供了change事件来响应变化，它会传入一个参数​value​。

<template>
  <el-radio-group v-model="radio">
    <el-radio :label="3">备选项</el-radio>
    <el-radio :label="6">备选项</el-radio>
    <el-radio :label="9">备选项</el-radio>
  </el-radio-group>
</template>

<script>
  export default {
    data() {
      return {
        radio: 3,
      }
    },
  }
</script>

按钮样式

按钮样式的单选组合。

只需要把​el-radio​元素换成​el-radio-button​元素即可，此外，​Element Plus​ 还提供了size属性。

<template>
  <div>
    <el-radio-group v-model="radio1">
      <el-radio-button label="上海"></el-radio-button>
      <el-radio-button label="北京"></el-radio-button>
      <el-radio-button label="广州"></el-radio-button>
      <el-radio-button label="深圳"></el-radio-button>
    </el-radio-group>
  </div>
  <div style="margin-top: 20px">
    <el-radio-group v-model="radio2" size="medium">
      <el-radio-button label="上海"></el-radio-button>
      <el-radio-button label="北京"></el-radio-button>
      <el-radio-button label="广州"></el-radio-button>
      <el-radio-button label="深圳"></el-radio-button>
    </el-radio-group>
  </div>
  <div style="margin-top: 20px">
    <el-radio-group v-model="radio3" size="small">
      <el-radio-button label="上海"></el-radio-button>
      <el-radio-button label="北京" disabled></el-radio-button>
      <el-radio-button label="广州"></el-radio-button>
      <el-radio-button label="深圳"></el-radio-button>
    </el-radio-group>
  </div>
  <div style="margin-top: 20px">
    <el-radio-group v-model="radio4" disabled size="mini">
      <el-radio-button label="上海"></el-radio-button>
      <el-radio-button label="北京"></el-radio-button>
      <el-radio-button label="广州"></el-radio-button>
      <el-radio-button label="深圳"></el-radio-button>
    </el-radio-group>
  </div>
</template>
<script>  export default {
    data() {
      return {
        radio1: '上海',
        radio2: '上海',
        radio3: '上海',
        radio4: '上海',
      }
    },
  }
</script>

带有边框

设置border属性可以渲染为带有边框的单选框。

<template>
  <div>
    <el-radio v-model="radio1" label="1" border>备选项1</el-radio>
    <el-radio v-model="radio1" label="2" border>备选项2</el-radio>
  </div>
  <div style="margin-top: 20px">
    <el-radio v-model="radio2" label="1" border size="medium">备选项1</el-radio>
    <el-radio v-model="radio2" label="2" border size="medium">备选项2</el-radio>
  </div>
  <div style="margin-top: 20px">
    <el-radio-group v-model="radio3" size="small">
      <el-radio label="1" border>备选项1</el-radio>
      <el-radio label="2" border disabled>备选项2</el-radio>
    </el-radio-group>
  </div>
  <div style="margin-top: 20px">
    <el-radio-group v-model="radio4" size="mini" disabled>
      <el-radio label="1" border>备选项1</el-radio>
      <el-radio label="2" border>备选项2</el-radio>
    </el-radio-group>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        radio1: '1',
        radio2: '1',
        radio3: '1',
        radio4: '1',
      }
    },
  }
</script>
