react-router與react-redux跳轉後保存store數據(基於"react-router": "^2.8.0")

1.router引入

import { Route, IndexRoute, Router, hashHistory, browserHistory } from 'react-router';
<Router routes={routes} history={browserHistory}/>

假設store結構以下,分別是主頁home,詳情頁detail,評論頁comment

{
    comment: {
        comments:[],
        leng:0
    }
    detail: {
        content: "xxx"
    }
    home: {
        loading: false,
        pos: 0,
        stories: []
    }
}

2.在主頁home跳到詳情頁detail時,在主頁實現獲取詳情頁的請求數據,並賦予store,這樣store就保留home,

//在home裏面跳轉是觸發fetchDetailData
<Link to={ '/detail/'+item.id}  onClick={this.props.fetchDetailData.bind(this,item.id) }>

獲取完詳情數據後,這樣store數據就成如下結構 react

{
    comment: {
        comments:[]
        leng:0
    }
    detail: {
        content:"xxx"
    }
    home: {
        loading:false
        pos:29228
        stories:Array(201)
    }
}

3.在詳情頁detail跳到評論頁comment時,在詳情頁detail實現獲取評論頁comment的請求數據,並賦予store,這樣store就保留home,detail的數據了

//在詳情頁detail裏面跳轉是觸發fetchCommentData
<Link to={ '/comment/'+this.articleId}  onClick={this.props.fetchCommentData.bind(this, this.articleId) }>評論</Link>

獲取完評論數據後,這樣store數據就成如下結構 webpack

{
    comment: {
        comments:Array(20)
        leng:20
    }
    detail: {
        content:"xxx"
    }
    home: {
        loading:false
        pos:29228
        stories:Array(201)
    }
}

4.這樣,當要返回是時還原狀態就能夠從本地緩存的store裏面取數據渲染。

//在返回主頁home時,在主頁作判斷,回到最初的最初點擊跳轉時的位置 componentDidMount () { if(this.props.stories.length === 0 ){ this.props.fetchHomeData(this.s) }else{ console.log(this.props.route.component.displayName) if(this.props.route.component.displayName == "Connect(Home)"){ window.scrollTo(0,this.props.pos); } this.s() } }
