react路由传参(3种方式)
1、params传参(刷新页面后参数不消失,参数会在地址栏显示)
路由页面:<Route path='/demo/:id' component={Demo}></Route> //注意要配置 /:id
路由跳转并传递参数:
链接方式:<Link to={'/demo/'+'6'}>XX</Link>
或:<Link to={{pathname:'/demo/'+'6'}}>XX</Link>
js方式:this.props.history.push('/demo/'+'6')
或:this.props.history.push({pathname:'/demo/'+'6'})
获取参数:this.props.match.params.id //注意这里是match而非history
1、params传参(多个动态参数)
state={
id:88,
name:'Jack',
}
路由页面:<Route path='/demo/:id/:name' component={Demo}></Route>
路由跳转并传递参数:
链接方式:<Link to={{pathname:`/demo/${this.state.id}/${this.state.name}`}}>XX</Link>
js方式:this.props.history.push({pathname:`/demo/${this.state.id}/${this.state.name}`})
获取参数:this.props.match.params //结果 {id: "88", name: "Jack"}
2、query传参(刷新页面后参数消失)
路由页面:<Route path='/demo' component={Demo}></Route> //无需配置
路由跳转并传递参数:
链接方式:<Link to={{pathname:'/demo',query:{id:22,name:'dahuang'}}}>XX</Link>
js方式:this.props.history.push({pathname:'/demo',query:{id:22,name:'dahuang'}})
获取参数: this.props.location.query.name
3、state传参( 刷新页面后参数不消失,state传的参数是加密的,比query传参好用)
注:state 传参的方式只支持Browserrouter路由,不支持hashrouter
路由页面:<Route path='/demo' component={Demo}></Route> //无需配置
路由跳转并传递参数:
链接方式: <Link to={{pathname:'/demo',state:{id:12,name:'dahuang'}}}>XX</Link>
js方式:this.props.history.push({pathname:'/demo',state:{id:12,name:'dahuang'}})
获取参数: this.props.location.state.name
