javascript - 用于动态创建组件的 React v4 路由

Question

我有一个用于创建 ReportCard 组件的对象列表。当用户单击这些 ReportCard 之一时，我希望它路由到 ReportDetail 组件，获取通过 URL 参数传递的 ReportCard 的 ID 属性。问题是 ReportDetail 组件接收到的 Match.Params 对象返回参数:{id: ":id"}。我认为我创建这些组件的方式是导致问题的原因。

我尝试更改 ReportCard 组件的生成方式。通过更改位置和标签的级别。

1. 报表区域组件根据报表对象的数量创建报表卡组件。
2. 每个 ReportCard 组件都有一个链接标记。
3. 所有 ReportCard 组件都有 1 个路线标记。
4. 我想将 ReportCard 中的 report.id 传递到 ReportDetail 的路由 URL 参数中。

感谢任何帮助，对所有代码表示抱歉。

报告卡组件:

  export default class ReportCard extends React.Component<DetailsProps, 
    any> {
    props: any;
    constructor(props: DetailsProps) {
    super(props);
    }
  public render() {
      const match = this.props.match
      return (
      <div>
      <Card className="subPanel" key={this.props.id}>
        <CardImg className="imagesec" src="https://via.placeholder.com/150"

报告详细信息组件:

 interface DetailParams {
    id: string;
  }

  interface DetailsProps {
    required: string;
    match?: match<DetailParams>;
  }

export default class ReportDetail extends React.Component<DetailsProps,any> 
  {
   props: any;

   constructor(props: DetailsProps) {
     super(props);

  }

  public render() {
     const {match} = this.props;

        </h2>

        }

Answer 1

问题是<Link to = "/reports/:id"> 。此语法正是您想要的 Route 的语法，但对于链接，您应该拥有实际的 id。像这样的东西:

const path = "/reports/" + report.id;
return <Link to = {path}>...
