value 和 onChange 需要配合使用。
## en-US
`Value` and `onChange` should be used together,
````jsx
import { TimePicker } from 'antd';
const Test = React.createClass({
getInitialState() {
return {
value: null,
};
},
onChange(time) {
console.log(time);
this.setState({ value: time });
},
render() {
return <TimePicker value={this.state.value} onChange={this.onChange} />;
},
});
ReactDOM.render(<Test />, mountNode);
