html引用外部文件单独定义react组件

<script type="text/babel" src="DryRadio.js"></script>
<script type="text/babel">
ReactDOM.render(<DryRadio/>, document.getElementById('root'));
</script>

```

其中`DryRadio.js`文件内容如下

```
const Radio = antd.Radio;

const options = [
    {value: '1', label: '语文'},
    {value: '2', label: '数学'},
    {value: '3', label: '英语'}
];

class DryRadio extends React.Component
{
    state = {value: '2'};

onChange = e => {
        this.setState({value: e.target.value});
    };

render(){
        return (
            <div>
                <Radio.Group name="test" options={options} onChange={this.onChange} value={this.state.value}/>
            </div>
        );
    }
}

1.组件名称必须首字母大写

2.onChange函数需要使用箭头函数，否则this含义不一样
