在React-Router中通过Link传递道具 [英] passing props with Link in React-Router

问题描述

您好，我正在尝试使用来自React Router的链接组件将道具传递给Details组件.我不想在页面上显示Detail组件，单击按钮时它应该呈现，但是当新组件呈现时，URL看起来也应该像这样的"/details/KvhNJecsqr6JFMSRTS".

Hello i'm trying to pass Props to a Details Component with the Link Component from React Router. I don't want to display the Detail Component on the page, it should render when a button is clicked but also the url should look like this '/details/KvhNJecsqr6JFMSRTS' when the new Component renders.

 class  Card extends Component {
                    render(props){
                    return(
                   <Col xs={12} md={4}>
                    <Thumbnail src="./someiamge">
                      <h3>{this.props.cardHeading}</h3>
                      <p>{this.props.cardDesc}</p>
                        <Button bsStyle="primary">Mieten</Button>&nbsp;
                        <Button bsStyle="default"><Link to='/details' params={{cardId: this.props.cardId}} 'here i wanna pass some props how i do this ?' >Details</Link></Button>
                    </Thumbnail>
                  </Col>

                    )
                  }
                }

export default Card

这是我的路由器的东西

<BrowserRouter>
          <div>
              <Route name='details' path='/details/:cardId' component={Details}/>
            </div>
          </div>
</BrowserRouter>

hier是我的Details组件:

hier is my Details Component:

    class Details extends Component {
      render() {
        return (
          <div >
            <div style={{textAlign: "left"}}>
              <h3>{this.props.cardHeading}</h3>
              <p>{this.props.cardDesc}</p>
              .......
            </div>
          </div>
        );
      }
    }

    export default Details;

推荐答案

如果希望您的新路由类似于/details/:cardId，那么我想这应该就足够了:

If want your new route to be like /details/:cardId, then I guess this should be enough:

<Link to={`/details/${this.props.cardId}`} />

但是，如果您想添加一些额外的属性，请按照文档，您可以在location.state中传递它们:

But, if you want to add some extra properties, then according to documentation, you could pass them in the location.state:

<Link to={{
  pathname: `/details/${this.props.cardId}`,
  state: { 
    cardHeading: 'This is a heading',
    cardDesc: 'Description'
  }
}}/>

然后，为了访问组件中的此状态，可以使用this.props.location.state或this.props.history.location.state

Then, in order to access this state in your component, you can use the this.props.location.state or this.props.history.location.state
