reactjs - typescript 中的 react 模态

Question

我正在使用 react-modal 在 Typescript React 设置中制作模态。

这是模态文件:

import * as React from 'react';
import * as ReactModal from 'react-modal';

class MyModal extends React.Component<any, any> {
  constructor () {
    super();
    this.state = {
      showModal: false
    };

    this.handleOpenModal = this.handleOpenModal.bind(this);
    this.handleCloseModal = this.handleCloseModal.bind(this);
  }

  handleOpenModal () {
    this.setState({ showModal: true });
  }

  handleCloseModal () {
    this.setState({ showModal: false });
  }

  public modalState () {
    const stateRef = this.state;
    return stateRef["showModal"];
  }

  render () {
    return (
      <div>
        <button onClick={this.handleOpenModal}>Trigger Modal</button>
        <ReactModal
          isOpen={this.modalState()}
          contentLabel="Minimal Modal Example"
        >
          <button onClick={this.handleCloseModal}>Close Modal</button>
        </ReactModal>
      </div>
    );
  }
}

这就是我使用它的方式:

import * as React from 'react';
import {UndoRedo} from './undo-redo';
import * as MyModal from './my-modal';

export class Header extends React.PureComponent<any, {}> {
  public render() {
    return (
      <header className="header">
        Header
        <UndoRedo/>
        <MyModal/>
      </header>
    );
  }
}

这是我遇到的错误:

ERROR in ./src/components/header/index.tsx (11,10): error TS2604: JSX element type 'MyModal' does not have any construct or call signatures.

我环顾四周，没有看到任何采用基于类的方法解决相同问题的方法。我所看到的似乎是基于缺少的渲染功能。我确实尝试过公开渲染，但没有帮助。

该错误消息表示您导入不正确。你应该导出你的类并正确导入它

export default class MyModal extends .... 

然后当你导入它的时候

import MyModal from './my-modal';
