Make it pop up under some conditions.

````jsx
import { Popconfirm, Switch, message } from 'parkball';

class App extends React.Component {
  state = {
    visible: false,
    condition: true, // Whether meet the condition, if not show popconfirm.
  }

  changeCondition = (value) => {
    this.setState({ condition: value });
  }

  confirm = () => {
    this.setState({ visible: false });
    message.success('Next step.');
  }

  cancel = () => {
    this.setState({ visible: false });
    message.error('Click on cancel.');
  }

  handleVisibleChange = (visible) => {
    if (!visible) {
      this.setState({ visible });
      return;
    }
    // Determining condition before show the popconfirm.
    console.log(this.state.condition);
    if (this.state.condition) {
      this.confirm(); // next step
    } else {
      this.setState({ visible }); // show the popconfirm
    }
  }

  render() {
    return (
      <div>

          title="Are you sure delete this task?"
          visible={this.state.visible}
