router动态传值

1.设置规则

 <Route path="/list/:id"  component={List}/>
            {/* 1.规则 */}

2.传值（或在地址栏自己设置）

 <li><Link to="/list/123">列表</Link></li>

3.接收值

import React, { Component } from 'react'


class List extends Component{
    constructor(props){
        super(props);
        this.state={}
    }
    render(){
        return(<h2>6666666666666666- {this.state.id}</h2>)
    }
    componentDidMount(){
        console.log(this.props)
        //接收router传的值
        let tempId=this.props.match.params.id
        this.setState({id:tempId})
    }
}
export default List

 

 模拟个人博客跳转

import React, { Component } from 'react'
import {Link} from 'react-router-dom'


class Index extends Component{
    constructor(props){
        super(props);
        this.state={
            list:[
                {cid:123,title:'Simoon的个人博客1'},
                {cid:456,title:'Simoon的个人博客2'},
                {cid:789,title:'Simoon的个人博客3'}
            ]
        }
    }
    render(){
        return(
            <>
        <h2>Simoon</h2>
        <ul>
            {
                this.state.list.map((item,index)=>{
                    return(
                        <li key={index}>
                            <Link to={'/list/'+item.cid}>{item.title}</Link></li>
                    )
                })
            }
        </ul>
        </>
        )
    }
}
export default Index
