Radio单选框

用于在多个备选项中选中单个状态。
和 Select 的区别是，Radio 所有选项默认可见，方便用户在比较中选择，因此选项不宜过多。

最简单的用法。

一组互斥的 Radio 配合使用。


const RadioGroup = Radio.Group;
class App extends React.Component {
  state = {
    value: 1,
  };
  onChange = e => {
    console.log('radio checked', e.target.value);
    this.setState({
      value: e.target.value,
    });
  };
  render() {
    return (
      <RadioGroup onChange={this.onChange} value={this.state.value}>
        <Radio value={1}>A</Radio>
        <Radio value={2}>B</Radio>
        <Radio value={3}>C</Radio>
        <Radio value={4}>D</Radio>
      </RadioGroup>
    );
  }
}
ReactDOM.render(<App />, mountNode);

通过配置 options 参数来渲染单选框。

import { Radio } from 'antd';
const RadioGroup = Radio.Group;
const plainOptions = ['Apple', 'Pear', 'Orange'];
const options = [
  { label: 'Apple', value: 'Apple' },
  { label: 'Pear', value: 'Pear' },
  { label: 'Orange', value: 'Orange' },
];
const optionsWithDisabled = [
  { label: 'Apple', value: 'Apple' },
  { label: 'Pear', value: 'Pear' },
  { label: 'Orange', value: 'Orange', disabled: false },
];
class App extends React.Component {
  state = {
    value1: 'Apple',
    value2: 'Apple',
    value3: 'Apple',
  };
  onChange1 = e => {
    console.log('radio1 checked', e.target.value);
    this.setState({
      value1: e.target.value,
    });
  };
  onChange2 = e => {
    console.log('radio2 checked', e.target.value);
    this.setState({
      value2: e.target.value,
    });
  };
  onChange3 = e => {
    this.setState({
      value3: e.target.value,
    });
  };
  render() {
    return (
      <div>
        <RadioGroup options={plainOptions} onChange={this.onChange1} value={this.state.value1} />
        <RadioGroup
          options={optionsWithDisabled}
          onChange={this.onChange3}
          value={this.state.value3}
        />
      </div>
    );
  }
}
ReactDOM.render(<App />, mountNode);

单选组合 - 配合 name 使用

可以为 RadioGroup 配置 name 参数，为组合内的 input 元素赋予相同的 name 属性，使浏览器把 RadioGroup 下的 Radio 真正看作是一组（例如可以通过方向键始终在同一组内更改选项）。

实色填底的单选按钮样式。

import { Radio } from 'antd';
ReactDOM.render(
  <div>
    <div>
      <Radio.Group defaultValue="a" buttonStyle="solid">
        <Radio.Button value="a">Hangzhou</Radio.Button>
        <Radio.Button value="b">Shanghai</Radio.Button>
        <Radio.Button value="c">Beijing</Radio.Button>
        <Radio.Button value="d">Chengdu</Radio.Button>
      </Radio.Group>
    </div>
    <div style={{ marginTop: 16 }}>
      <Radio.Group defaultValue="c" buttonStyle="solid">
        <Radio.Button value="a">Hangzhou</Radio.Button>
        <Radio.Button value="b" disabled>
          Shanghai
        </Radio.Button>
        <Radio.Button value="c">Beijing</Radio.Button>
        <Radio.Button value="d">Chengdu</Radio.Button>
      </Radio.Group>
    </div>
  </div>,
  mountNode,
);

不可用

import { Radio, Button } from 'antd';
class App extends React.Component {
  state = {
    disabled: true,
  };
  toggleDisabled = () => {
    this.setState({
      disabled: !this.state.disabled,
    });
  };
  render() {
    return (
      <div>
        <Radio defaultChecked={false} disabled={this.state.disabled}>
          Disabled
        </Radio>
        <br />
        <Radio defaultChecked disabled={this.state.disabled}>
          Disabled
        </Radio>
        <div style={{ marginTop: 20 }}>
          <Button type="primary" onClick={this.toggleDisabled}>
            Toggle disabled
          </Button>
        </div>
      </div>
    );
}
ReactDOM.render(<App />, mountNode);

垂直的 RadioGroup，配合更多输入框选项。

按钮样式

按钮样式的单选组合。

import { Radio } from 'antd';
const RadioButton = Radio.Button;
const RadioGroup = Radio.Group;
  console.log(`radio checked:${e.target.value}`);
}
ReactDOM.render(
  <div>
    <div>
      <RadioGroup onChange={onChange} defaultValue="a">
        <RadioButton value="a">Hangzhou</RadioButton>
        <RadioButton value="b">Shanghai</RadioButton>
        <RadioButton value="c">Beijing</RadioButton>
        <RadioButton value="d">Chengdu</RadioButton>
      </RadioGroup>
    </div>
    <div style={{ marginTop: 16 }}>
      <RadioGroup onChange={onChange} defaultValue="a">
        <RadioButton value="a">Hangzhou</RadioButton>
        <RadioButton value="b" disabled>
          Shanghai
        </RadioButton>
        <RadioButton value="c">Beijing</RadioButton>
        <RadioButton value="d">Chengdu</RadioButton>
      </RadioGroup>
    </div>
    <div style={{ marginTop: 16 }}>
      <RadioGroup disabled onChange={onChange} defaultValue="a">
        <RadioButton value="a">Hangzhou</RadioButton>
        <RadioButton value="b">Shanghai</RadioButton>
        <RadioButton value="c">Beijing</RadioButton>
        <RadioButton value="d">Chengdu</RadioButton>
      </RadioGroup>
    </div>
  </div>,
  mountNode,
);

大中小三种组合，可以和表单输入框进行对应配合。

import { Radio } from 'antd';
const RadioButton = Radio.Button;
const RadioGroup = Radio.Group;
ReactDOM.render(
  <div>
    <div>
      <RadioGroup defaultValue="a" size="large">
        <RadioButton value="a">Hangzhou</RadioButton>
        <RadioButton value="b">Shanghai</RadioButton>
        <RadioButton value="c">Beijing</RadioButton>
        <RadioButton value="d">Chengdu</RadioButton>
      </RadioGroup>
    </div>
    <div style={{ marginTop: 16 }}>
      <RadioGroup defaultValue="a">
        <RadioButton value="a">Hangzhou</RadioButton>
        <RadioButton value="b">Shanghai</RadioButton>
        <RadioButton value="c">Beijing</RadioButton>
        <RadioButton value="d">Chengdu</RadioButton>
      </RadioGroup>
    </div>
    <div style={{ marginTop: 16 }}>
      <RadioGroup defaultValue="a" size="small">
        <RadioButton value="a">Hangzhou</RadioButton>
        <RadioButton value="b">Shanghai</RadioButton>
        <RadioButton value="c">Beijing</RadioButton>
        <RadioButton value="d">Chengdu</RadioButton>
      </RadioGroup>
    </div>
  </div>,
  mountNode,
