何时使用

代码演示

基本使用

请确保Radio具有相同的name属性以实现单选功能。

import { Radio } from 'choerodon-ui/pro';
function handleChange(value) {
  console.log('[basic]', value);
}
ReactDOM.render(
  <div>
    <Radio name="base" value="A" onChange={handleChange} defaultChecked>A</Radio>
    <Radio name="base" value="B" onChange={handleChange}>B</Radio>
    <Radio name="base" value="C" onChange={handleChange}>C</Radio>
  </div>,
  mountNode
);

绑定数据源

绑定数据源

import { DataSet, Radio } from 'choerodon-ui/pro';
function handleDataSetChange({ value, oldValue }) {
  console.log('[dataset newValue]', value, '[oldValue]', oldValue);
}
const data = [{ bind: 'A' }];
class App extends React.Component {
  ds = new DataSet({
    data,
    fields: [
      { name: 'bind' },
    ],
    events: {
      update: handleDataSetChange,
    },
  });
  render() {
    return (
      <div>
        <Radio dataSet={this.ds} name="bind" value="A">A</Radio>
        <Radio dataSet={this.ds} name="bind" value="B">B</Radio>
        <Radio dataSet={this.ds} name="bind" value="C">C</Radio>
      </div>
    );
  }
}
ReactDOM.render(
  <App />,
  mountNode
);

按钮显示效果

import { Radio } from 'choerodon-ui/pro';
function handleChange(value, oldValue) {
  console.log('[button]', value, '[oldValue]', oldValue);
}
ReactDOM.render(
  <div>
    <Radio mode="button" name="base" value="A" onChange={handleChange} defaultChecked>A</Radio>
    <Radio mode="button" name="base" value="B" onChange={handleChange}>B</Radio>
