我在React中有一个带有onChange事件的组件.在下面的代码中,我需要声明在调用时调用正确的方法

this.props.onChangeImage()

在Gallery组件中调用.

export class Form extends React.PureComponent {

  componentDidMount = () => {
    this.props.getUser();
    this.props.getImages();
    this.props.getBoards();
  }

  render() {
    if (this.props.pin === null) {
      let boards = [];
      boards = this.props.boards;
      boards = boards.data.map(
        (item) => <MenuItem key={item.id.toString()} value={item.name} primaryText={item.name} />
      );
      return (
        <div>
          <Helmet
            title="Form"
            meta={[
              { name: 'description', content: 'Description of Form' },
            ]}
          />
          <Gallery images={this.props.images} onChange={this.props.onChangeImage} />
        </div>
      );
    }
    return (<div className="spinner-container"><CircularProgress /></div>);
  }
}

下面,在onChangeImage方法中,我试图断言调用sendEventToParentWindow方法.

function mapDispatchToProps(dispatch) {
  return {

    onChangeImage: (event) …
