[英]React js : import component to route
I have class like this in reactjs 我在reactjs中有这样的类
class Topics extends React.Component {
constructor(props){
super(props);
this.state ={
url:props.match.url,
path:props.match.path
}
}
render(){
return (<div>
<h2>Topic</h2>
<ul>
{topics.map(({ name, id }) => (
<li key={id}>
<Link to={`${this.state.url}/${id}`}>{name}</Link>
</li>
))}
</ul>
<Route path={`${this.state.path}/:topicId`} component={TopicDetails}/>
</div>)
}
}
I am trying to load TopicDetails
component in a route.The TopicDetails
我试图加载TopicDetails
组件在route.The TopicDetails
topicDetails.js topicDetails.js
const TopicDetails = ({match}) => {
const topic = topics.find(({ id }) => id === match.params.topicId);
return (<div>
<h2>Details</h2>
<h2>{topic.name}</h2>
<p>{topic.description}</p>
</div>
)
}
export default TopicDetails;
My question is how can properly add the component which is imported?? 我的问题是如何正确添加导入的组件?
Since you are exporting TopicDetails as default export you can import it like 由于您将TopicDetails导出为默认导出,因此您可以像导入它一样
import TopicDetails from './TopicDetails'; //here specify the correct path of TopicDetails functional component
Complete code is here 完整的代码在这里
import TopicDetails from './TopicDetails';
class Topics extends React.Component {
constructor(props){
super(props);
this.state ={
url:props.match.url,
path:props.match.path
}
}
render(){
return (<div>
<h2>Topic</h2>
<ul>
{topics.map(({ name, id }) => (
<li key={id}>
<Link to={`${this.state.url}/${id}`}>{name}</Link>
</li>
))}
</ul>
<Route path={`${this.state.path}/:topicId`} component={TopicDetails}/>
</div>)
}
}
