在点击响应中打开新窗口中的组件 [英] Open a component in new window on a click in react

问题描述

我有一个显示数据的组件。我必须在新窗口中单击父组件的按钮/链接打开此组件。

I have a component which displays a data. I have to open this component in a new window on clicking a button/ link from a parent component.

export default class Parent extends Component {
    construtor(props) {
        super(props);
    }

    viewData = () => {
        window.open('childcomponent.js','Data','height=250,width=250');
    }

    render() {
        return (
            <div> <a onclick={this.viewData}>View Data</a></div>
        )
    }
}

我不知道如何调用另一个组件并将其显示在指定的新大小窗口中。

I dont know how to invoke another component and also display it in a new size specified window.

实际上我需要向该子组件发送一个道具，用它从数据库中获取数据并渲染它。

Actually I need to send a props to that child component with which it will fetch me the data from database and render it.

推荐答案

您可以使用 ReactDOM .createPortal 在新窗口中呈现组件 David Gilbertson 在他的发布：

class MyWindowPortal extends React.PureComponent {
  constructor(props) {
    super(props);
    // STEP 1: create a container <div>
    this.containerEl = document.createElement('div');
    this.externalWindow = null;
  }

  render() {
    // STEP 2: append props.children to the container <div> that isn't mounted anywhere yet
    return ReactDOM.createPortal(this.props.children, this.containerEl);
  }

  componentDidMount() {
    // STEP 3: open a new browser window and store a reference to it
    this.externalWindow = window.open('', '', 'width=600,height=400,left=200,top=200');

    // STEP 4: append the container <div> (that has props.children appended to it) to the body of the new window
    this.externalWindow.document.body.appendChild(this.containerEl);
  }

  componentWillUnmount() {
    // STEP 5: This will fire when this.state.showWindowPortal in the parent component becomes false
    // So we tidy up by closing the window
    this.externalWindow.close();
  }
}
