使用按钮和关闭图标关闭 React Semantic UI 模式

Question

我有一个模态框，用户需要在其中填写一些表格并保存通过模态框中的按钮填写的所有内容。当用户保存时，我希望模式关闭。我可以通过在 Modal 组件上使用 open 道具来完成这项工作。但是如果我这样做，当我尝试通过 closeIcon 这样做时，模态不会关闭。

我该怎么做才能让用户通过这两种方法关闭模态框？

这是我当前的模态代码：

  handleCreateButton (evt) {
    evt.preventDefault()
    // ...
    // code to save whatever was typed in the form
    // ...

    this.setState({showModal: false})
  }

  renderModalForm () {
    const {
      something,
      showModal
    } = this.state

    // if I have the open props, I get to close the Modal after the button is clicked
    // however, when using the icon or clicking on dimmer it wont work anymore.
    return (
      <Modal closeIcon closeOnDimmerClick open={showModal} trigger={<Button onClick={() => this.setState({showModal: true})}><Icon className='plus'/>New Challenge</Button>}>
        <Modal.Header>My Modal</Modal.Header>
        <Modal.Content>
          <Form>
            <Form.Input
              label='Something'
              value={something}
              onChange={(evt) => this.handleChangeForms('something', evt.target.value)}
            />
            <Button onClick={(evt) => this.handleCreateButton(evt)}>Save</Button>
          </Form>
        </Modal.Content>
      </Modal>
    )
  }

当您使用 open 道具时，您还需要使用 onClose 处理程序道具。
顺便说一下，closeOnDimmerClick 默认设置为 true。

这是一个运行示例：

const { Modal, Form, Button, Icon } = semanticUIReact;

class App extends React.Component {

  constructor(props) {
    super(props);
    this.state = {
      something: '',
      showModal: false
    }
  }

  handleChangeForms = (e, { value }) => {
    this.setState({ something: value });
  }

  handleCreateButton(evt) {
    evt.preventDefault()
    this.closeModal();
  }

  closeModal = () => {
    this.setState({ showModal: false })
  }

  render() {
    const {
      something,
      showModal
    } = this.state

    return (
      <Modal closeIcon onClose={this.closeModal} open={showModal} trigger={<Button onClick={() => this.setState({ showModal: true })}><Icon className='plus' />New Challenge</Button>}>
        <Modal.Header>My Modal</Modal.Header>
        <Modal.Content>
          <Form>
            <Form.Input
              label='Something'
              value={something}
              onChange={this.handleChangeForms}
            />
            <Button onClick={(evt) => this.handleCreateButton(evt)}>Save</Button>
          </Form>
        </Modal.Content>
      </Modal>
    )
  }
}

ReactDOM.render(<App />, document.getElementById("root"));
