1.x에서 2.x 로의 업그레이드 안내서에서 :
<Link to>, onEnter 및 isActive 사용 위치 설명자
<Link to>문자열 외에도 위치 설명자를 사용할 수 있습니다. 쿼리 및 상태 소품은 더 이상 사용되지 않습니다.
// v1.0.x
<Link to="/foo" query={{ the: 'query' }}/>
// v2.0.0
<Link to={{ pathname: '/foo', query: { the: 'query' } }}/>
// 2.x에서 여전히 유효
<Link to="/foo"/>
마찬가지로 onEnter 후크에서 경로 재 지정에도 위치 디스크립터가 사용됩니다.
// v1.0.x
(nextState, replaceState) => replaceState(null, '/foo')
(nextState, replaceState) => replaceState(null, '/foo', { the: 'query' })
// v2.0.0
(nextState, replace) => replace('/foo')
(nextState, replace) => replace({ pathname: '/foo', query: { the: 'query' } })
사용자 지정 링크와 같은 구성 요소의 경우 router.isActive, 이전 history.isActive에도 동일하게 적용됩니다.
// v1.0.x
history.isActive(pathname, query, indexOnly)
// v2.0.0
router.isActive({ pathname, query }, indexOnly)
/ideas/${this.props.testvalue}}> {this.props.testvalue} </ Link>
