import { Popover, Button } from 'antd';

const App = React.createClass({
  getInitialState() {
    return {
      visible: false,
    };
  },
  hide() {
    this.setState({
      visible: false,
    });
  },
  handleVisibleChange(visible) {
    this.setState({ visible });
  },
  render() {
    const content = (
      <div>
        <a onClick={this.hide}>关闭卡片</a>
      </div>
    );
    return (
      <Popover content={content} title="标题" trigger="click"
        visible={this.state.visible} onVisibleChange={this.handleVisibleChange}
      >
        <Button type="primary">点击弹出卡片</Button>
      </Popover>
    );
  },
});

ReactDOM.render(<App />, mountNode);
